Topic: Let's discuss Blüthner

A lot of discussions about D4, and nothing about Bluthner To tell the truth, for me there is still a lot of job for Modartt about catching Steinway’s (D4) timbre and adding hammer/strings interaction moments. But Blüthner... is my love. Marvelous model, especially v5. Before I never used basic presets, but after the last release standard Bluthner presets often sound during the day in my room.

Here I created a demo from midi: Yulianna Avdeeva plays Brahms. Blüthner + few plug-s.
http://www.forum-pianoteq.com/uploads.p...vdeeva.mp3
Wonderful, isn’t it?

Still, in my opinion, treble range isn't perfect (though in this recording I tried to fix it by different plugs and PT preset): a little bit long sound, much high overtones and a lack of hammer hit. This range, IMO, is the last Bluthner weak point, which is not brought to mind. Unfortunately, “Direct sound duration” and “Impedance” influence not only sustain but also attack. And increasing of “hammer noises” don’t give needed result, though slightly improves situation.

Let's compare the middle part of this Intermezzo.
1.    Pianoteq Bluthner. Studio Recording AB, without any additional effects and plug-s.
http://www.forum-pianoteq.com/uploads.p...eva%29.mp3
2.    Real studio recording, Emil Gilels. From 1m1s:
http://youtu.be/4dXz0Csfmsc?t=1m1s
3.    Galaxy Vintage D playing the same midi excerpt.
http://www.forum-pianoteq.com/uploads.p...eva%29.mp3

Though comparing is not clear (it would be better to use D4 among other Steinways), but you can notice that the sound of recorded piano is not so “flying” and “open” as in PT audio: real one has much round, woody and short character with clearer hammer hits. Hope, that Modartt will continue to improve treble range (D4, by the way, has the same problem) in next versions, as it was improved from 4 to 5.

Nevertheless, I am confident, Pianoteq's Bluthner is the best success in piano physical modelling!)

Was just playing on the blüthner right now, i really like its majestic, slightly metallic tone.

Re: Let's discuss Blüthner

During V4, i liked Bluthner very much, and was not convinced by D4.
With V5 D4 has made huge improvments and Bluthner.... not so much. The Bluthner has a "metalic" overtone that is too much "pianoteqish" for me.
Also, like always it's a bit of an illusion to think you can correct its defaults with the settings, only a new version can do that.

That's the aliquot stringing doing that, I'm pretty sure. Not Pianoteq's fault IMHO

Hard work and guts!

Re: Let's discuss Blüthner

All in all the Blüthner piano still is my favorite Pianoteq instrument (and yes, I have started 'collecting' a few). In fact it was the reason I bought Pianoteq (that, and the flexibility of a modelling instrument). The Blüthner Model One is one of the most beautiful virtual instruments I know, and at least from my point of view quite without serious competition.

(Also let's not forget we are complaining on an extremely high level nowadays... and sampled instruments are neither more 'perfect' by definition nor is the approach without serious drawbacks.)

I hear this high overtones in D4 model too. But may be different ears and different equipment.
Here is high range of
1. D4 2. Bluthner 3. Vintage D
http://www.forum-pianoteq.com/uploads.p...s_high.mp3
For me, in this example only Vintage D has naturaly souding recorded high notes - round and without ringing overtones. Both D4 and Bluthner are "pianoteqish" in treble

Me too: decided to buy Pianoteq after Bluthner add-on was released

It's a good sign, that we compare PT sound now with best recorded sampled pianos and real recordings. And still we hear, that timbre is not natural enough: something about attack/sustain, overtones, and high notes, I think. We must discuss it, for Modartt to see different opinions and criticism, not only praise. It will help them to move forward and develop our lovely PT. And of course, sampled pianos are imperfect, especially in playability, where they certainly lose in battle with pianoteq.
P.S. Somewhere on pianoworld one man wrote, that he don't hear surpassing playability of PT over sampled pianos. "only 5 milliseconds or something like that.", - he said

The problem with sampled libraries is that trying to make them 'perfect' is a losing game, actually. If you want responsiveness and low latency, you have to limit their size quite severely, which in turn limits detail quite drastically.

Some numbers: let's say we sample only with 44/16, which is physiologically as 'perfect' as it gets without unnecessary overhead (i.e., let's not start the 192/24 debate here), and we still get into trouble. We have 88 notes on a grand piano. The attack sample size has to be at least 30 seconds in the bass, 15 seconds in the treble notes before looping just to sound 'decent'. In other words that is still actually rather short (i.e. will lead to unnatural behaviour in very long chords, for example). But let's say we have attack samples of 20 seconds on average, and 10 velocity layers. This means 88x20x10=17600 seconds of audio, or almost 5 hours of high quality samples. Meaning... an uncompessed size of 3GB, or at least 300MB when quite heavy lossy compression is being used. And these are rather conservative estimates.

The problem with strong compression in memory is that it takes lots of time. Also most formats introduce quite high latencies all by themselves (e.g. MP3 and Vorbis about 100ms, FLAC still minimally around 5-10). On the other hand, you can't really expect to be able to hold 3GB of samples in memory. Reading them on demand from disk is also out of the question.

There are good reasons most 'hardware' pianos employ quite drastic measures to keep sample sizes reasonably small (and they can at least use ROM memory which incurs virtually no latency), like: lower sample quality, less layers, shorter attack sample sizes and such, which all lose lots of details. Then velocity morphing and DSP effects are used to mask that lack of detail. Even in the case of a very large sampled instrument with lots of layers, you still have to employ velocity morphing or you effectively end up with just 10-20 actual velocities, which is something people with good hearing will notice, and the larger your samples, the more work it is.

...and all these points still leave out the basic fact that certain details simply cannot be sampled properly: like sympathetic string resonances, for example. I.e. those are either actually 'modelled' even in a sampled library, or the result is just pathetic. That said, most current high-quality sample libraries are very cool indeed... but they are compromises, as every practical piece of software always is. And I would really be surprised if a sample library actually manages an effective latency of less than say, 50ms or so. Pianoteq's latency is certainly not zero, but I guess it might win that contest at least quite easily.

Thanks for your post, good written! And I can say moreover - latency must be present for natural response. Nearly 10-20ms (depends on keyboard). Cause real piano has complicated mechanism, which doesn't respond instantly. I remember one discussion in Internet, where latency was debated. One sample library company decided to include this natural latency in their samples. And only after user's disturbance (as equipment and software give it's own latency + this recorded) they cut out pauses in the begining of notes.

That is why I was joking about "only 5 milliseconds or something like that". Cause when we talk about playability, we mainly mean not latency (it must be appropriate, comfortable and nothing else; most libraries can ensure it on modern computers). What we mean is natural behavior: firstly, continuous dynamic range, that allows to intonate long melodies; resonances, true pedalling, staccatos and other piano nuances, which are inflexible in sampled libraries; opportunity to make legato and cantilena. There are composers particularly sensitive to playability. For example Chopin, because he had long melodies with a lot of nuances and melisms. Playing few nocturnes or slow etudes with Acoustic grand, Pianoteq and sampled piano, shows all the difference. Pop-music and other genres (with a lot of arpeggio, chords and short, simple melodies) are not so sensitive and in many cases can afford themself libraries with 10-20 layers.

But there is already a lot said about physical/sampling and doubt we will say something new .

With Kontakt Player and Vintage D, the asio driver is set to 2ms, but the actual latency reported by Kontakt is indeed 40ms+, which is probably one of the reason you feel less "connected" with software samplers.

Re: Let's discuss Blüthner

Well remambered.

It's importante to be aware of each piano own characteristics before blame pianoteq.

It's strange... someones complained about bass.. other people about trebble, and other about midle range.

Everyone will compare pianoteq tone with the real piano models or even digital pianos they were used to play.

I would call that the 'hybrid' approach: cache parts of the samples in memory and only load the rest on demand. Also, with ever increasing memory sizes and CPU speeds, there will be a time when caching 'everything' in RAM will probably not be a challenge anymore. But we are not there yet.

Re: Let's discuss Blüthner

I really am into the Pianoteq Bluthner as well. The Bluthner Daily preset is my go-to piano.

Yet while we're talking about improvements, another un-piano like characteristic that I mentioned in another thread is a subtle phase-shifting effect that I hear when I play closed chords. With P4, I heard what someone else said was a whooshing sound when playing chords with the pedal down. This has largely disappeared with P5 but not entirely.

Outside of this, there is nothing else for me that strongly betrays the Bluthner as not a piano. I don't care if it sounds like a real Bluthner, but I do care that it sounds pleasing to the ear and real.

This would depend on the convolution reverb effect - it has several different latency modes, including a zero latency mode. I assume that Galaxy didn't set up the convolution reverb unit/s to that zero latency mode.

I thought I'd try out Galaxy's Vintage D and Synthogy's Ivory II:
http://www.try-sound.com/detail.asp/galaxy_vintage_d/en

Although these were played over the internet the connection was good and I could get the general sense of the software. I'd say the Ivory sounded better than the Galaxy, but both seems to have shorter notes than Pianoteq. The Galaxy sounded flat and a bit stifled. Ivory's sound was silky and smoother, but lack the depth of what I hear when ever I hear a real acoustic grand. Maybe the having the actual software loaded gives them more depth. When I hear acoustic grand pianos they all have bright and metallic quality in the sound.

Here are a few links, listen to the brightness of the Steinway in these tutorials:
https://www.youtube.com/watch?v=CC6bgBA8en8

https://www.youtube.com/watch?v=aKVLXDS4De0
https://www.youtube.com/watch?v=fAzwviInwoU

The Bluethner seems to need less tweaking, maybe this is because Modartt worked in collaboration with Bluethner to produce it. Where as the D4 v5 (Steinway) seems a good piano to create other sounds from. I tried tweaking the Bluethner, but always felt the pre-sets weren't really improved upon.

Its subjective.
Hear's an interesting talk:

Re: Let's discuss Blüthner

Hm. When I think about metallic or 'brassy' sound and/or exceeding brightness, I mostly think about Yamaha pianos (both grands and uprights). I suppose it depends on what you are looking for. Yamaha grands are actually praised for being able to push through better in certain types of mix.

Thanks for combining a rather bold statement with an ad hominem insult to anyone not sharing your opinion.

I am a bad player. I will give you that. But I am also a physicist, and knowing how a piano action works, I would be very interested in hearing how a 'good' player can influence the sound of the instrument just by playing, i.e. just by changing the way they press the keys. It is, in my very humble opinion, simply impossible.

Let's think about it for a minute: the piano is purely a mechanical device. You create sound by pushing buttons and pressing pedals; usually you never touch the strings directly (yes, there are some jazz players... but that's beside the point). The main parameter is the velocity with which the hammer hits the string. And since the hammer in that moment is not even in contact with the key at all, it really is 'just' the hammer velocity. The player can control the velocity before the hammer escapes, and also the release velocity, but the latter is a rather subtle effect on how quickly the sound is damped.

Apart from attack and release velocity, there is only the pedals. And yes, dropping the dampers quickly or slowly of course makes a difference. But this is actually something modern electronic pianos simulate quite nicely. I am sorry, but I just don't see any magical part of the player's "touch" that cannot be captured by today's sensors, especially when I think of a good tri-sensor controller that transmits key-on/-off velocities as well as continuous sustain pedal values.

What you say about the physical sound of the piano, that is, as measured as opposed to heard, is of course correct.  But those who assert the opposite, while they seem to be arguing for something magical, are also pointing, inexactly, to something real.  Sound as we hear it as human beings is is a complex perceptual phenomenon, and the control of touch and other parameters, for combinations of piano sounds, can have significant changes on sounds as we perceive them.  Pianists often talk about this as the creation of illusion; but "illusion" suggests that there is a kind of hearing available to us that is free from it, so that isn't quite right.  It is, however, a way of hacking our perceptual apparatus to achieve certain combinatorial effects -- for instance, the use of timing and contrast to call attention to different phases of the piano sound's decay.  When a pianist says that s/he makes the sound, not the piano, this is the skill that is meant, and it is really true, if by sound you mean, not the measurements made by simple unbiased non-biological instruments, but those made by our own highly biased faculties.  All the pianist really knows is that they have a certain sound in mind, and they make some small adjustments so that it comes back at them, more or less.  There is no way in practice to fully know what those adjustments are; they are deeply internalized.

I don't think this is very different than saying that a great painter can create a sense of color and light that is unique and personal, even though all the paint used came out of factory-made tubes.

I largely agree with your points, though I very often think a lot of it is akin to a placebo effect, or more correctly termed 'confirmation bias'. That is, someone expects some specific result and this in itself changes their perception. However, the claim I was critising was it being allegedly dependent on the player how bright or 'metallic' a piano sounds. And that is something I still don't believe: either the harsh overtones are present or they are not, end of story. The piano tuner can change that, not the player.

Its true that there are a variety of standards, from absolute beginners to performing a piano concerto at the highest level. I wasn't really addressing someone's playing ability, I was simply saying what I generally hear in grand pianos. The clips showed what I was getting at. The range that they have, from a low percussive sound to an ear piercing shrill, from soft playing to the attack and every thing in between. The piano has the capability of being all these.
Thanks for the video clip . The recording was a bit muffled and most probably cut out some of the tonal range of the performance, but I could still hear a bright sound in that piano. I would imagine that the pianist in the clip had it tuned to the concert he was going to perform. I have different headphones (six) with varying frequencies. Some of them omit sounds in Pianoteq that are present in others.
When I tried the Galaxy and Ivory I thought they both sounded good. If you owned either of them and just played them at home you should be satisfied with them. Its only when you start to compare them with the detailed sound that acoustic pianos have, then you'll be disappointed, or not quite satisfied.
The piano software developers have all done a tremendous job in allowing us to have a grand piano in are houses. I think Pianoteq produces sound and depth very close to what real pianos produce. Though there's always room for improvement. I'm sure healthy and constructive criticism will always be welcomed.

A Steinway D Hamburg?

Hello, kalessin! Sorry, if I was too harsh in my words: sometimes it's just no time to use more smiles or to write IMHO one more time

Glad to get acquainted with you! I am not physician, but musician and (my second education) psycho-physiologist (the perception of music is my theme). As for the piano teacher, meeting different pupils on one instrument in one day - it's not surprising for me that one piano can have different timbre. I hear it every day. Moreover, this effect is preserved even with one pupil - when his arms are at the begining and after a year, when we made a lot of work about sound and his arms.
And good pianist can show, how many paints and variants of timbre can be extracted from one instrument. Of course, we can't strongly change the sound and of course we largely depend on piano we have: it's sound, it's quality, it's opportunities (as one have great variety of paints in itself, and one is blankly). But though our influence is not too big, sound can be changed.

Magic? Placebo? No, I don't think so. I am not physicist, as I said, but understand that sound is complex and can be achieved by different ways: by the speed of an arm, by the deepness of touch, and more complex - we say "by the weight of an arm". And all this become a hammer characteristics. Combining this parametres in different ways, we achieve changes in sound. In my opinion, understanding and hearing of this effect depends on musical experience: how many piano music you've heard (jazz, academical, pop and etc. Different pianists, piano models), how many acoustic pianos you've played and how long, what did you played (improvising a real piano - good way to find it). Though, I am convinced, there are still good pianists, who will not share my opinion. And it's normal, and i'am glad that you think (and has your own evidence) different.

Small addition: hitting the strings by an arm is not what only jazz players do - yes, academical composers use it too, and for more then century

Re: Let's discuss Blüthner

Still, i agree with kalessin that from a mechanical point of view, for each note, other than playing it soft or loud (and the pedals) there's not 56 different ways of playing it: you press down on a key, and then you release the key.

Re: Let's discuss Blüthner

I half remember an anecdote about Cortot.  Apparently a pupil was appalled at the state of Cortot's piano (a Pleyel, I think) and could not get anything pleasing out of it.  When Cortot sat down to demonstrate a passage, the pupil was amazed at the beautiful sounds coming out of it. Now, Cortot was an exceptional pianist and he was very accustomed to his own piano, but it does indicate that there is more to creating a beautiful sound than appears possible from the mechanics.  When I come to think of it, the piano is technically a percussive instrument and it can of course be played as one, but composers from JSB onwards have written music for fortepiano/piano requiring a singing tone and the voice is not a percussive instrument.  So we are all in some way creating an illusion, right from our first lesson.

Re: Let's discuss Blüthner

The funny thing is, when the hammer hits the string, it has already 'escaped' the key (hence the 'escapement' in the mechanics of the action). That is, it is swinging freely in that moment, and literally the only remaining parameter is the speed with which it hits the string.

Of course there are other influences: timing plays an important role, and maybe even very slight variations of a few milliseconds can subtly change the impression. Normally it is estimated that anything below 5ms cannot be perceived at all, but MIDI is dangerously close to that threshold even under optimal conditions. However, a human player would still need to play this precise, and that's a wholly different story. I still think those effects (if existing at all) would be rather small, however, and I would very much like some blinded test for that. The problem of course being that a really blind comparison between the real thing and an electronic keyboard is virtually impossible.

Re: Let's discuss Blüthner

Interesting,

The problem is the gap between what pianists say or feel and the fact that the piano is indeed a mechanical instrument.
My piano's teacher speeks about colors, tones... I don't understand all what he says but I think he is probably right: there must be a lot more than only the mechanical aspects. But all these subtle nuances represent maybe 5% of the piano sound, and require a high level to be expressed, IMO... I don't know...

The fact is that I can't imagine in what a subtle nuance with my finger (other than speed or strenght) could result in any effect on the hammer

Re: Let's discuss Blüthner

I do remember seeing a Swedish TV documentary a both Jan Johansson.
http://en.wikipedia.org/wiki/Jan_Johansson_(musician)
Most famous for this one I guess: https://www.youtube.com/watch?v=LMgitKv-78I
STV tested people on the street, playing 1,2 or 3 notes from Visa Från Utanmyra. Several people needed only one note to recognise the player…
Not top science I know, but sure colours and tones.

Re: Let's discuss Blüthner

Hm. You mean, they recognised the piece, and associated that with Mr Johansson. I very much doubt that most 'people on the street' can do more than that, as actual musicians are a minority. And if they really could recognise at least 3 different players, then there of course is the whole rhythm and dynamics thing that no one really doubted is an important factor. In other words: I would find it quite believable that a pianist has a certain acoustic 'thumbprint' that is recognisable... but it probably is recognisable completely independent of the actual piano. And since the recent discussion was started over the question whether the pianist can actually modify the sound of the instrument just by hitting the keys differently, we are talking about different things.

Thank you for putting so well, from another amateur pianist and ex-physics student.

I remember those arguments from my youth -- say, 50 years ago.  Acoustic pianos haven't changed much, digitals have gotten _much_ better, and the arguments _haven't changed at all_.

It's a classic "religious argument":

. . . there's no compelling evidence for either side;
. . . opinions are held very strongly;
. . . nobody changes his mind.

PS -- If you look at Rachel Jimenez' blog, one or two posts back, she discusses this problem of "expectations" and non-objective factors in perception.   It's a very complicated issue.

Re: Let's discuss Blüthner

I uploaded a little audio with Avdeeva playing Brahms on Youtube. 2 Fantasien. One of them was in the beginning of this topic before.
Intrested in your comments about sound and realness/unrealness of Bluthner. Did the sound of original Bluthner modell become better after modifications, or not? I tried to reach atmospere of classical recording by tweaking PT and using different plug-s in Cubase. Do you like this sound, or it seems not real/"tasty" enough? All opinions are appreciated!

Re: Let's discuss Blüthner

Interesting discussion.  I haven't read everything but will throw in my opinion.  I have a VPC1 and have played around with the velocity curves a bit.

With pianoteq v5, my opinion is that the bass is better on the D4, but the the treble is better on the Bluthner.  The bass strings need to have a bite when played loudly, and this is lacking on the Bluthner.  On the D4, the bass sounds quite good, but when you get in the treble, it starts to sound cheap.  Anyway, pianoteq keeps getting better.

Re: Let's discuss Blüthner

Kridlatec,

Your recording sounds very good. There's a sense of formality--the piano is kept slightly away from us--but it still has force, and the piano is entirely convincing. I can't imagine anyone hearing anything other than a real piano.

Re: Let's discuss Blüthner

Very nice Brahms pieces, Kridlatec. I like the recording sound and the Blüthner is very appropriate for these rather dark and meditative pieces. The only restriction (for me) is that the long singing notes in the second piece sound a bit static. I guess you enhanced the soundboard resonance a bit to get this long sustain, but I would suggest adding some "bloom" to the sound by detuning the unisons a tiny bit. The tuning in this case is slightly too "perfect".

Re: Let's discuss Blüthner

Just wanted to chime in on the debate as to whether a player can change the timbre of a note via any means other than velocity. This comes up regularly on the piano teachers' facebook groups (I fall firmly in the "No" camp), and is always in relation to the "digital vs acoustic" argument.

The main point I want to make is that no one (in the "Yes" camp) seems to take into account the fact that skilled players can also make any digital piano sound much better than a lesser player can, and that this is largely a matter of technique.

I think that players who think they can influence the timbre of a single note independently of velocity are being misled by the way they listen to the sound. What I have seen is that these players have learned to listen for the sweet-spots in the piano's timbre, not by how loud the sound is, but by how the harmonics bloom. This makes good sense, as it encourages the player to judge their dynamics by quality of tone. I suspect that the way this is perceived from the resonance of a real acoustic grand is mostly impossible to recreate with amp+speakers, and as such, the player's expectations will not be met.

Another thing I have seen is that some teachers with this anti-digital attitude encourage their students to set the volume of their digital pianos to full, as they think that this more closely matches the sound of a real grand. I'm sure most of us would agree that this is very likely to end up making for a very unpleasant experience for home players, as the highest settings are only really necessary for playing in larger rooms, such as school halls. This, again, suggests that players who are privileged enough to teach/play on grands have not had the opportunity or inclination to spend sufficient time with a digital for their expectations to adjust accordingly.

Re: Let's discuss Blüthner

Ben,
What an interesting and thoughtful - and plausible - response to the puzzle of how pianists create different timbres. Wouldn't pianoteq work in the same way? With different velocities of touch producing different patterns of harmonic 'bloom' in the sound?
Clive.

Re: Let's discuss Blüthner

Yes, Clive, I think it does this very well - but would still require such a player to adjust, as the effect of an entire grand piano, resonating as one entity (but also interacting with the room acoustics), cannot be effectively reproduced by a couple of cones and tweeters, IMO. The other problem - that of the sheer volume of sound that a grand creates - is also difficult to address for the same reasons as I outlined above, namely that to achieve that sense of immersion from speakers, you will likely end up with them being uncomfortably loud.

Re: Let's discuss Blüthner

Can we change the timbre – and Bluthner?

Thank you,Ben, and all others in this ”Lets discuss Bluthner”! Thank you for sharing your knowledge and ideas. This is really a forum giving useful advise and thoughts.
When I was a child, my friends changed timbre with thumbtacks on hammers (which was not good). Then I saw, that when I pressed the key, the hammer moved towards the strings. But, before it contacted the string I had no more control from the key - it was disconnected.  I had kind of no  contact . So, in that way, the timbre is set by the velocity of the hammer. Anyway to, maybe, bring one new thing to this, if we play f or ff, it make the hammers ”freetime” shorter, so I think a  pianist know this and can this way use it to change the timbre. At the end , changing timbre,  seems to me,  to be a combination of  keytouch,  velocity of hammers, and talented pianists. But that we already knew – or did we? This said from ”not a pianist ”point of view.
I have always liked to experiment vid sounds/timbre myself, and now I have Pianoteq/Bluthner, and can change the sound as I like. What makes Ptq/Bluthner outstanding? I can not at all dive so deep in the understanding of all technological terms as all of you in this forum, but, as someone said – I do not know how it works, why it works – but it is the feeling. All my life, I have been searching for good pianosounds, but I was never satisfied. I played once in TV with my orchestra years ago, music in radio, and those sampled pianosounds was used(Roland, Korg among others).  Now I have Ptq, and sampled sounds feels sterile and cold (some of them good though).  ”Make large and small adjustments everywhere. You can create almost any sound that a piano can create, and more”(this from Pianoteq manual). That is something fantastic for me. I enjoy playing Ptq, Bluthner, and waiting for Modartt making Pianoteq better and better. This ”soundarea” is of course, in my opinion, something that will never be completed, and that is the way it has to be – continued development. And – thank you all, for diving so deep in these discussions in the forum. You have so much talent and knowledge. Reading forum is learning.
And, thank you, Modartt.

Re: Let's discuss Blüthner

In last patch 5.1.3 Bluthner was revoiced. I think, attack became more clear. And shorter, more precise notes in treble range. For me Bluthner model became better once more. What do you think, guys, do you hear changes?)

Re: Let's discuss Blüthner

Pianos make sound.  Pianists make music.  The problem with "Pianoman Chuck" reviews of digital pianos is that he doesn't really play with much expression or color.  Great pianist really can't play well on a poor quality piano, because the piano itself is too limiting.  In contrast a poor player is not of much use even on the finest piano.  In the end it is the emotional response of the listener that counts.  Creating music is all about creating a mood or feeling within the listener.  It requires subtlety, emotion, and surprise.  Since this thread is about the PT Blüthner, it's the voice to which I was most drawn.

You don't play with your fingers, you play with your mind.  It's the brain that counts, not simply the fingers.  The brain controls the movement of the fingers, which in turn make the instrument "sing."

Re: Let's discuss Blüthner

Greetings!
I took the opportunity of the black Friday discount and upgraded from standard to Pro. I also updated Pianoteq from v5.1.2 to v5.1.3...
I brought Pianoteq's internal frequency to match my external soundcard freq (96KHz). Then I played the Blüthner and I was blown away for the difference in sound. For me it was as if I installed a new piano. I wasn't expecting that!
Now, I'll have to make more experiences to find out where differences resides, probably this weekend I'll have more answers. Was the Pro sound engine? the matching of the frequencies? the modifications introduced to v5.1.3? 
Did anybody else just updated and perceived the same (big) difference in sound?
Regards.

Re: Let's discuss Blüthner

Probably the 5.1.3 modifications. Pro engine sounds exactly the same as Standard engine. I suppose the sample rate increase could have improved the precision of transients a bit, but I wouldn't mark it as a world of difference from regular 44.1/48k...

Hard work and guts!

Re: Let's discuss Blüthner

Yes, I think that was the update to v5.1.3. I already noticed from other posts that the sound engine is the same for all Pianoteq versions. And since I´m nearly 50 years old, I know that my ears don't have the sensibility to notice the differences in the upper freqs.

Funny the human mind, I really do feel differences (using headphones) when using different internal sampling rates... I know it is subjective but I do notice a difference (even in a blind test)...

Anyhow, for me, Pianoteq's Blüthner is still my go to piano and it continues to get better and better!

Kudos to Modartt!!!!

Re: Let's discuss Blüthner

Why need for sample rates > 44 kHz at all? Human can't listen higher 20 kHz. So, Nyquist's theorem guarantee that 40 kHz sampling rate is sufficient. Why need for 96, 192 kHz?

As mentioned above, when you have twice or four times as much samples in the same amount of time, you can represent very short transient changes (like attack of a drum hit, or the noise when a hammer hits the string) that much more precisely.

Hard work and guts!

Re: Let's discuss Blüthner

EvilDragon, I can't understand. Any sound signal is infinite sum of sinus waves (Fourier), human's ears cut out only 20-20000 Hz band of sound spectrum. Any lower or high frequency parts of the signal ignored by ear. So, Nyquist theorem guarantee exactly recovering signal up to frequency F if sample rate > 2F. So, why need for 96 kHz and 192 kHz?

Can anybody provide two files with the same signal but one with 44kHz, second with 96kHz sampling that sounds different?

I guess, two reasons are right. I know, I heard few times from other users, that changing frequences doesn't change the sound. I definetely can't agree. I don't know, if soundcard/drivers/musical pitch or individual anatomy influence this process, but I hear great (great) difference between 41/44 and 96. In my case it's so. And no one will dissuade me
And yes, patch 5.1.3 (I wrote above about it) made Bluthner sound more strict and shaped. In my opinion, attack became better.

I'm sorry EvilDragon, but that just isn't accurate. Recordings at 44 Khz can record any audio signal with perfect accuracy, short transients and all. The only reason why higher samples are useful has to do with the increased headroom for anti-aliasing low-pass filters.

As for Pianoteq and higher sample rates in general: people should do a double blind test to find out whether they're actually able to accurately identify higher sample rates (using a good DA converter). I'm pretty certain that virtually no one will.
