5.1.3 areas for improvement?

If I can suggest to the Pianoteq's team, for a future version, if it is possible:

A true parametric EQ, with the 3 classical parameters (Frequency, Gain and Q) could be helpfull to reduce some unpleasant frequencies due to our speaker systems or rooms without the need of additional external EQ.
I find the actual EQ not user friendly. Just my opinion

Pianoteq's EQ and external EQ are different things, because Pianoteq's one works in early pre-processing stage, not in post-processing. From manual:

A good preamp section for the EPs.

There is a little bit more than distortion (different type of saturation depending on the model used, noise, dampening of certain frequencies).
It is possible to build similar sounding instruments by tweaking the interface but it is not that easy for somebody who doesn't actually know how the preamp shaped the sound or what type of built-in tremolo is suitable for each specific EP.
It would make more sense to me to have all these controls in a preamp section, just like the one you find on the real EPs, making the tweaking effortless and providing a virtual model more close to the original.

Thank you, I hadn't seen that

One way to do this is loading a preset having no notes altered, freeze spectrum profile, and then load the one you want to zero out. Don't forget to clear the freeze panel afterwards of course...

I agree, and that might the same issue as the dull 'pedal down repeat' sound...no twang where it should be more and more amplified...
It can be modestly improved with the use of some convolution reverbs (I use free ones).

The interpolation scheme that the Pianoteq team developed is a mathematical wonder to me.  Having worked with additive synthesis in the early '80s and then later with early sampling technology makes me appreciate  their ingenuity.

To wit:   Toggling a "yellow square" to "on" at the bottom of a single note in the spectrum note editor will allow the user to change the level of the fundamental and relative harmonics of a single note.  And, as it is, there will be an effect on adjacent notes over a given range.  What some may not know is that in lieu of toggling all of the yellow squares, the note RANGE over which the editing of one note will affect adjacent notes is determined by the distance you would select two adjacent squares - each to the side of the one you are editing.  This allows the interpolation note RANGE to be determined by the user.

Absolute kudos to such a controlled mathematical algorithm.  (however it works!)

good morning

on my side the implementation of GPU acceleration would be interesting, enabling (or improving the possibility) for some of us to re-dispose outdated notebook / netbooks for the exclusive use of Pianoteq

it would be also interesting enabling midi-out in Pianoteq so to make possible to bridge other software instruments without the need to use Jack or other virtual midi port software

like other people I would like additional instruments addons (such a Fazioli addon) and the possibility in Pianoteq stage to tune sustain pedal action

You can already assign almost all controls to a MIDI message, so a great amount of control is already possible with Pianoteq...

D4 and Bluethner are very good in Pianoteq 5. But I would like in future see more realistic K2 and U4. Currently lt it has slightly synthetic sound. When I play or listen most of website's demos, I feel that this is a synthesizer, not an acoustic piano (I don't feel that on D4 and Bluethner). K2 has beautiful and realistic chords, but unrealistic single notes. U4 has very realistic upper range (listen Italian Polka from website), but unrealistic below. I can't describe this in more formal way, sorry. Maybe this is just my taste. So, this is not a feature request, just my thoughts.

The new model for una corda is much more realistic indeed! More contrast with the normal sound, and a much more singing tone at soft velocity. I guess what's new is that the free strings not touched by the hammers are allowed to add some sort of sympathetic resonance. Will this model be included in other pianos in the future?

Did not checked the last update since I'm using exclusively Bluethner. While trying the left pedal a while ago I found it worth using and hope to see the things to be changed in future. So how did it work before this 5.1.4 update and still working on other pianos except D4? Did it just make the usual sound a few decibels quieter with no remodelling, i.e. just one string involved, or even 2 strings in the middle position for continuous controllers? I definitely request some advanced approach for the left pedal because it is just essential to have it usable.

Thank you very much for the reply. Ok, I see, I trust you more then myself in this topic. From my experience as a pianist and a listener (and it is just huge), left pedal sure used by pianists for aesthetic purposes, not just to make it quieter or easier to play PPP - it should add some otherwordly colour, usually it sound slightly rugged due to the felt quality as you mentioned - as far as I could understand it is less teared and compressed on the hammers in the places where it hit that una string. With maybe very few exceptions when you play, say, Chopin, in every one of his pieces you may find a phrase, or some melody in some reprise that you want to play that extremely intimate way. Please, please, please do some more investment in the development of the left pedal algorithms! (Bluethner especially, cause I use it alot, lol)

Ok, got it, should install right now.

Ok, gave it some test. Can't be 100% sure in my perception because just checked it compared to if you use it at least for a week extensively you just know the things from your guts, it became more then just some your opinion. From the first glance yes, it works, on D4, especially in the middle register, on highs it is a very subtle difference to my taste, same for the base. For my taste I feel that it is still not enough for me. But you know what? I went to my real grand, tried to play, and, what a surprise, did not hear the difference this time also! It is quite late where I live, I'll give it a more extensive test tomorrow. But for now I'd personally like it to add more "weakness" to the sound. Though, I repeat, I'm not 100% sure about what I'm saying this time, maybe it is really perfect right now. Same for the Bluethner - there IS the difference. The fact that it is still a digital model also able to fool me.

p.s. BTW in general my thought process is not that I compare Ptq with a real grand - rather I compare it with a 'recording' of a real grand.

...listening to some Michelangeli archive video recording right now - something changing slightly other way, it's a kind of equalization when he uses the una corda, the highs are obviously get cut, kind of...

Ah, I see, could check it in the trial version of Standard, I've got a Stage license.
