Topic: Modartt strategy

So it seems that Modartt is going the route of factory-authorized instruments that are distinctive in tonal character from other pianos. Makes sense, I suppose.

What would be coming out next then, do you suppose? I'd guess a Fazioli F308 or a Bösendorfer 290 Imperial. I'd think a Yamaha CFX and a Shigeru Kawai SK-EX would also be desired, but don't know if they'd want to cooperate with Modartt as they make their own digital instruments.

What I'd really like to see, however, is Pianoteq on iOS and improvements to the electric pianos.

Re: Modartt strategy

Hello,

Yes, maybe? will it be difficult for Modartt to collaborate officially with brands like Yamaha (and unfortunately perhaps even Bösendorfer - bought by Yamaha).

However, it remains the alternative of .fxp models, usable with the Standard version and buildable with the Pro version. Even if this approach meets its limits in the absence of specific model (desirable) for a given type of piano.
In the case of the Bösendorfer imperial, I invite you to revisit with the new version Pianoteq 6.2 the excellent model of .fxp created by sskuk1, which benefits greatly from the improvements of ptq 6.2 (link: Bosendorfer Imperial provided you have the model Blüthner of pianoteq )
Examples: (as files .mp3 generated by pianoteq are big, better is to download them on the "Other file" pianoteq forum menu bar)
Rachman prelude C sharp min op3 n2 / sskuk1 bosendorfer imperial / ptq 6.2.0
Mei-Ting-Sun-2009--feux-follets-liszt / sskuk1 fxp bosendorfer imperial / ptq 6.2.0

I have recently tried to build a Bosendorfer 200 .fxp based on the example of the .fxp sskuk1, having the chance to access a Bosen 200 family every day.
Overview same examples (work in progress) generated with pianoteq 6.2: (beware of the size of the files above 5mb (use preferably "other file" download on the menu bar.)
Rachman prelude C sharp min op3 n2 / overview fxp BM Bosen 200 V0.8 / ptq 6.2.0
Mei-Ting-Sun-2009--feux-follets-liszt / overview fxp BM Bosen 200 V0.8 / ptq 6.2.0

Being a former software developer (amateur pianist, unfortunately without the ear of a good piano tuner nor the mathematical skills to understand the detail of the modeling sought), I recorded each note of our piano level ff , retrieved the maximum level of each partial (based on the partial frequencies proposed by Pianoteq pro) by retrieving the spectrum values (Blackman-Harris) from Audacity, starting each sample analyzed at the beginning of the decay period of the 'envelope.
I used spectral windows halved each new octave (65k, 32k, up to 512 for the highest notes). to limit the loss of the level of high harmonics. Then comparing the level of each partial of the same note to the same level between pianoteq and the actual piano, for a given note, (automatically thankfully), I then place manually in the clipboard (Ctl-C / Ctl-V ), the edited result (in the format expected by pianoteq), so that Ptq retrieves it in its "note edit / spectrum profile" window.
The "raw" result is appalling, but by "reconstructing" a function of rescale dividing by 4 the level (dividing by more - according to an interpolled function imitating the rescale of pianoteq - when the difference exceeds 10db), we arrive at something listenable, or we find part of the timbre of the original piano (although less subtle than the .fxp starting sskuk1).
We also find some of the defects of the original piano bosen 200 (35 years old) that does not have the full extent of the imperial bosendorfer on which sskuk1 based and some parasitic vibrations in the acute. (At the current stage of my work as a beginner with Pianoteq pro, my .fxp is currently "mechanically" out of my computer processing without readjustment to the indisputably necessary ear.I would put the .fxp obtained on the site when I will have readjusted (for the capture of pianoteq) with version 6.2, and would do if I have the time a try also with the new model Steingraeber.

My need (besides a better ear and a more flexible wrist), would be to benefit in a future evolution of the pro version, more parameters to refine the setting obtained from a real piano. I thought I heard ? that the current "spectrum profile" impacts the harmonic balance produced especially at the beginning of the sound envelope. Ideally it should be? (if compatible with the mode of modeling) to be able to modify this balance between harmonics with other stages of the evolution of the envelope, at least at the time of the slow decay of the level.
For each note there are also modulations responsible for a rapid change in the balance between harmonics, which should also be able to be set, to give the "song" of each note an even more lively character.
I remain aware that this need, in addition to the important design work it requires must still be enforceable by a PC that is not a monster. However, it would be interesting to explore the tremendous power made available by the current graphics cards (I think the CUDA interface of Nvidia cards for example to massively parallel processing on several thousand processors - even if PC gammer are equipped fans whose noise seriously pollutes the shades made with a virtual piano)

Regards,

In addition,
you really have to take advantage of the new pianoteq piano model Steingraeber E-272
for which I can not help but listen to the same 2 extracts with the preset "recording1" (not modified): (pay attention to the size of mp3 files of 5Mo each)

It may be that "factory authorized" partnerships are a PART of their strategy.
As to why... ?
Available alternatives in the "marketplace" are mostly sample based, I say "based" because there is post processing to clean things up.
I don't know of any factory authorized sample libraries, but I don't follow that closely.
I do remember that in the early days of sampling there were some attempts to copyright instrument sounds, I don't know what happened to that.
The factory endorsement has value to both Modartt and to the wooden piano maker.
If we develop a preference for a particular pianoteq instrument we are more likely to look for that brand of physical wooden piano if/when we browse around the store, and buy it if/when funds permit.

I was pleased to see the Steingraeber E-272, it seems to be a break in the strategy toward modern pianos.

As far as IOS goes... I don't see any advantage for Modartt to go in that direction, other than exposure and exposure in the lo-fi arena would probably not be good.
JMAO, etc.

Your post reminded me of the Bösendorfer 290 that I emulated with my PtqSpecProf software (https://sites.google.com/site/ptqspecprof/software) from samples (similar to your approach) back in 2012. I re-rendered it with version 6.2.0 using yout MIDI file and I find a great improvement in sound with the new version, showing the steady progress done since that time (version 4)

Re: Modartt strategy

Hello,

Thank you for updating your .fpx de bosendorfer imperial.
Finally I published "as is" my current version of bosendorfer fxp 200 (V0.8) for ptq 6.2 (there is still a lot of work to improve it)
link: Bosendorfer 200 v0.8 for ptq 6.2.0 - work in progress -
I added a little demonstration of this fxp with the fantasy no 3 of Mozart K397 (unknown pianist, midi file: https://www.classicalmidi.co.uk/351fandm.mid )
link: fantasia no 3 in D - Mozart K397
If anybody wish try to make a Bosendorfer 200 fxp test, I added the original files that I recorded (note by note on the real piano/ ff level) to make this preset, links:

Well said! I love to see it on ios, that would be so useful. It seems Modartt are not interested, its such a shame.

Re: Modartt strategy

Absolutely not a shame in not being interested in iOS. Why would they want to give 30% of profits to Apple, and depreciate their own product (because they sure as hell cannot keep their current pricing structure for iOS)?

Because the market is much bigger and a touch interface is much nicer for use in a live setting? We’ve been down this road before, but changing the pricing structure doesn’t mean Modartt couldn’t make money. I think $40 for a single piano, with $40 in-app purchases for each additional piano would sell well. Or they could charge more and offer discounts to current owners, some new possibilities for pricing are opening up.

Apple has said before they didn’t mind losing computer sales to tablets, as long as it was to their own devices. I think Modartt should think similarly,  better to become the leader in the “mobile” device space than allow others to establish themselves in that position. I have NeoSoul Keys Studio for iOS now, and may not buy Pianoteq’s electric pianos. If I buy the iOS Ravenscroft 275 before the sale ends tomorrow, I may postpone buying Pianoteq for iOS or buy fewer instruments. Better to get in now and be the market leader if they still can, in my opinion.

Re: Modartt strategy

Much bigger market also cries for much more customer support. It's a rabbit hole.

Meanwhile, I'm very happy using Pianoteq as is with touch and all, on my Surface, and Modartt didn't need to change their pricing structure to satisfy lowest common denominators of Apple's walled garden realm. Hah!


I will be perfectly happy if Modartt continues to ignore iOS as they should, and focus more on their modeling technology, which is much more important.

Re: Modartt strategy

The continuation of this magnificent modeling effort is indeed a great hope, for many of us who are looking for new sounds, or who do not have an acoustic piano yet, either have them but at times when we can not we use it ...

In addition to these demonstration of pianteq 6.2.0 .fxp for Bosendorfer200/290 and Steintgraeber E272 here is in .flac format 96Khz / 24bits all the files indicated above generated by Pianoteq 6.2.0 pro (see the links below)
I also added in the .flac format 96khz / 24bits the files note by note of the levels pp to fff (in the great limits of the touch of the amateur pianist that I am) for the piano Bosendorfer 200 of 1983 (35 years) for who would like with pianoteq 6.2 make an improved fxp for this type of piano.
Warning: on the server of my ISP, these files are kept only 30 days.The download time can be important with files whose biggest reaches 1 GB for the samples of real Bosendorfer (only 40 to 50 MB for the demo songs of .fxp)
Any criticism to help us build even better fxp for these pianos would be welcome.

For those who regret the absence of files in 192khz format, attached this small comparative test done 1 year ago on the hearing accuity of people between 19 and 93 years (more than 105 db maximum level) with a relatively good DAC and Sennheiser HD800 headphones.

Very interesting test showing the toll taken by ageing on our hearing! Great sample...

Re: Modartt strategy

The topic Modartt strategy. In my opinion, Modartt’s strategy is simple and concise; they want to make modeled pianos for use with computers. I have been with Ptq since 2013, and have learned, that every now and then they make a new modeled piano. We got Steingraeber. Most likely there are soon more models coming. Of course. They know how to do it using modeling technology, for computers, not iOS. They like it, and it is certainly satisfying for them to read how happy we users are with Ptq. Philippe started the adventure of Ptq, and it’s so exciting. After 5 years, using Mac mini, i have to enthusiastically say, as a pianoteqenthusiast, Wow!
Well, that’s what I think about it.

Re: Modartt strategy

Furthermore, with the price difference between a Mac and a Linux PC (and even a Windows PC) with the minimum configuration for Pianoteq works well, it is possible to buy a correct USB DAC and already a good headphones to highlight the beautiful tone Pianoteq instruments.
By the way, you really have to try the Steingraeber E-272 model, even more enjoyable to play than to listen with midi files demonstration ...

Well, after all the earlier arguments against IOs (who needs tablets, technologically impossible, Apple is evil, too expensive, etc.) we now have the final death blow: it is unwise for companies to pursue a bigger market, as the costs of support would go up. Are you really serious?

Re: Modartt strategy

Absolutely serious. I do think that spending time on perfecting Pianoteq's modeling is much wiser use of manhours than spending it iOS and everything tied into it (and that obviously includes very much increased support needs).


And yes, Apple is evil.

Re: Modartt strategy

I actually feel the same and there is wisdom in it (in my opinion).

For stage use, gigging, etc, there are already great sounding options out there and the audience won't feel the difference in the least if you're using a high quality stage piano or a VST. But if you still want to go the VST rout, you could run it from a laptop / surface obviously.

And for home or studio use, whether playing or recording, when using high quality monitors or headphones and you feel every little nuance, personally I'd like it to be the best it can be, not a poorer version of the current product that would also dilute the company's ability to further improve the current product.

You can buy a used laptop that's much more potent than an iPad for about the same money. There's also mini PCs to be had for reasonable sums that easily outperform iPads. Why would you want a poorer quality app on the iPad? You can just as well use the internal sounds in that case.

Bottom line - for portability and gigging, you can use a laptop or a surface tablet, but why would you, when the difference in sound quality won't be perceived? You're better off using a good stage piano for a good number of reasons. And for home/studio use, personally I feel the best quality is the most desirable target.

PS. When going the PC route you can also get a large display (23-24", optionally with a touchscreen) to display the music.

About if apple is or not evil... i-things are expensive, sufficient reason for me to stay apart.

Well MS at least makes a tablet that can run Pianoteq without having a "special" version written for it. That is more benevolent than what Apple's doing.

Well, thank you! It got me into revisiting this software that I had sort of abandoned since the pianoteq model was so much improved. I am trying to use it with the real piano samples posted by bm (Bruno) of his Bösendorfer 200. This is my first chance to try it with a real recording. We'll see what comes out..

Re: Modartt strategy

I will be curious to discover the result ...
In late summer I intend to offer on the site also the recorded notes of a second piano (Erard Model No2 of 2.48m 1899 - parallel strings) just after it is retuned.

Bruno

Bosen200real35yOldSamplesFFlevelExceptb.flac (parts1+2)

Re: Modartt strategy

Here is my attempt at emulating with PtqSpecProf a Bösendorfer 200 starting from the pianoteq model closest in size and sound: the Steinway B Home preset.

FXP Corner: https://www.forum-pianoteq.com/file/cikc98o1

Audio: https://www.forum-pianoteq.com/uploads....1fandm.mp3

I used the very good recordings from Bruno’s post (Bosen200real35yOldSamplesFFlevelExceptb.flac) and got through the tedious job of extracting each note one by one and comparing to a similar MIDI file played in pianoteq to extract the spectrum changes, but it was a good use of a rainy afternoon finally…

Caveats: PtqSpecProf can only bring a current model closer to the target sound, it cannot for instance imitate the very obvious attack sound in the samples since there is limited control of this parameter in pianoteq. There is also a limitation added to the dynamics that I correct by using a velocity curve limited to 100. Higher values sound bad because the samples were done with that value.

This post may seem out of context with the thread subject, but may remind us of the uniqueness of Modartt’s contribution (and so, strategy) by the great flexibility of its editing possibilities! You don’t only buy a piano, you also buy a powerful tool to create other instruments.

Re: Modartt strategy

Very nice, Gilles, and so much 'cleaner' sounding than the preset based on the Bluethner for the Bosendorfer 200 - though the tone is different, the Bluethner version sounds as if I am listening through a sheet of drywall/gypsum board.  It's so hard to get these things "right"!  I have frequently lost patience when I try to tweak things.

I love the Steinway B, ever since version 6.1, which really breathed new life into it.  Closest thing to my Mom's 1957 "M".

- David

Re: Modartt strategy

By the way, Julien and Philippe, Gilles brings up a good point - can you grant us a control for note attack?  I had found that to be an issue when I was trying to emulate my own piano - the 'liveness' of the real thing is often conveyed by note attack and then decay.  In Pianoteq, the Hammer hardness is one way to influence attack, but then it doesn't really allow for both a hard attack and then a soft decay, which is key for an 'in-close' live piano in front of you.

- David

Re: Modartt strategy

I see the birth of some sort of "Bosendorfer ? ...me too" movement in this forum.

But I bet the imperial Bosendorfer add on probably will be created more later, when Modart technology will be even closer to please the few ultra hard critic guys who love samplers. And a Bosendorfer it's large, have extra strings, and I bet it will take some few move computer power.

Anyway it's interesting to see you guys trying to emulate a imperial Bosendorfer using the already exiting models.

Re: Modartt strategy

This attempt to create a .fxp from a Steinway B model is very interesting. I tried at the beginning without success to model some notes of this Bosendorfer from the model Steinway D (too different).
Gilles, at what stage of the envelope ADSR and on samples of what length do you capture the notes on the real piano and on Pianoteq (before comparison of the spectra). If this sample length varies according to the pitch of the note, do you give yourself a particular rule for choosing the start and duration of sample capture? What is the spectral analysis function do you use (rectangular)? The choice of this spectral function (rectangular, Hanning, Blackman, ..) is it a feedback of experience after comparison with other methods? Which method do you use to initially set the recordings of the real piano and Pianoteq at exactly the same volume level before comparing the spectra for a given note?
It will undoubtedly be necessary in the future to make a dedicated topic for these types of more technical questions that move away from the queries of users of this forum on Moddart's strategy.
For my part, my goal is not to make "alternative" piano models to those of Moddart necessarily much better equipped (especially with the mathematical modeling of the interactions between components of an instrument), but to learn how to help tools of Pianoteq pro to better discover how it is possible to create new sounds, starting (1st step for me) to get as close as possible to real instruments, which is possible only with access the instruments in question because it must be able to play or possibly recordings of real instruments of good quality but it makes the work more difficult without the feedback of the actual keyboard and the ability to control the sound recording.
I also wish, for sentimental reasons to try to "freeze" in fxp the timbre of the instruments that have rocked my childhood, before these instruments age too much, may be a day less well maintained while I'm not sure in the long run to recover them all.

I would like to try the Steingraeber model but I will need more time because my current treatments are only partially automatic. (The blackmann-harris spectrum analysis I'm using comes from Audacity) which forces me to export / import .csv for each note.
(If Gilles had the opportunity to test the Bosendorfer 200 on Steingraeber with his software, that would be great)
My professional activity leaves me only "windows" of an hour and a half very early in the morning and I still retain some of this time to learn to play better or compose (with Pianoteq of course). Near each lunch, I play again on the real Bosendorfer 200 family to keep in touch with the real sound that should guide me to improve my .fxp. To deepen my learning of the timbre of an instrument on a given note, I found it interesting to put on Audacity the free plug-in TRT Nova, which allows to listen in a comparative way in real time a recording by analyzing a thin slice of frequencies (that can be varied in real time) with a slope of 72 db / octave outside the frequency band analyzed. It helps me a lot to understand (unfortunately for me not related to mathematical modeling) how each string can "sing", with still very different modulations between Pianoteq and a real piano. The study of the ADSR envelope is also interesting, the structure of the attack phase remains very different for the low and mid-low notes, the decay phase is generally much shorter with Pianoteq than with a Bosendorfer 200 and the Pianoteq pro adjustment of the impedance & Q factor does not seem to allow to adjust it, acting mainly on the sustain phase (if there is a setting of the decay duration I am a taker). Reminder: I am only an amateur curious to better understand how is formed the sound of a piano, which is also a help to play discovering new sounds that can be reproduced on the keyboard in a composition or interpretation .

By the way, Julien and Philippe, Gilles brings up a good point - can you grant us a control for note attack?  I had found that to be an issue when I was trying to emulate my own piano - the 'liveness' of the real thing is often conveyed by note attack and then decay.  In Pianoteq, the Hammer hardness is one way to influence attack, but then it doesn't really allow for both a hard attack and then a soft decay, which is key for an 'in-close' live piano in front of you.

I would say the decay does not really concern the hammer noise, but essentially the string partials, which can be controlled by several parameters including unison, direct sound duration and soundboard impedance.

Re: Modartt strategy

OK, then let me re-phrase the question - What controls other than hammer noise can 'sharpen' the attack of each note?  A sharp attack appears to be part of the brilliance that is magical when standing or sitting very close to a real piano.

Maybe effects (EQ, compressor)? Post-processing? The "distance" between a raw recording and the final sound, whether it be music, samples library..., is simply amazing.

Hi Philippe
Hi dkein

I think Flux Bitter Sweet transient designer will be your best friend to control notes attack in Pianoteq without compressing the sound nor modifying the hardness of the hammers.

Re: Modartt strategy

In fact, any good transient designer will do... NI has one that is pretty great as well.

Hard work and guts!

Very nice, Gilles, and so much 'cleaner' sounding than the preset based on the Bluethner for the Bosendorfer 200 - though the tone is different, the Bluethner version sounds as if I am listening through a sheet of drywall/gypsum board.  It's so hard to get these things "right"!  I have frequently lost patience when I try to tweak things.

I love the Steinway B, ever since version 6.1, which really breathed new life into it.  Closest thing to my Mom's 1957 "M".

You are right that the Bluthner version is much less precise, but remember that it was done by comparing with pianoteq version 4. I did not redo the analysis I just rendered the same fxp with version 6.2.0.

The "big and round" sound obtained with Bluthner is still interesting for some repertoire, but of course the Steingraeber has attained such a degree of clarity that everything pales when compared to it, even the more recent Steinway B...


EDIT: I think I read you wrong and you were talking about Bruno's fxp, not mine for the 290...sorry. I guess the difference is due to the distance between the Büthner, a large piano with the much much smaller 200...

This attempt to create a .fxp from a Steinway B model is very interesting. I tried at the beginning without success to model some notes of this Bosendorfer from the model Steinway D (too different).
Gilles, at what stage of the envelope ADSR and on samples of what length do you capture the notes on the real piano and on Pianoteq (before comparison of the spectra). If this sample length varies according to the pitch of the note, do you give yourself a particular rule for choosing the start and duration of sample capture? What is the spectral analysis function do you use (rectangular)? The choice of this spectral function (rectangular, Hanning, Blackman, ..) is it a feedback of experience after comparison with other methods? Which method do you use to initially set the recordings of the real piano and Pianoteq at exactly the same volume level before comparing the spectra for a given note?

As I write in the PtqSpecProf pdf doc, I tried many lengths but short ones (around 1.5 seconds) give good results as well as being practical to shorten the total work. Your samples are longer but I still compared with shorter ones from pianoteq, what is captured really is an average spectrum at the start of the note, the decay is to be handled by pianoteq itself. I can use all the common windows, but for a short sample rectangular works fine. My default number of samples for the FFT is 16384, but I can go higher. I found the relative volume has no real importance (apart from the spectrum content itself) since the spectrum is more or less auto-scaling from 0 dB down. I also center the resulting changes around the average value.

This is all amateur work, I am not an expert in signal processing, but conversations with Philippe at the time revealed no bad mistakes on my part if I remember well.

One very useful tool in the Spectrum Profile tool is the rescale function. I use it a lot when the given result sounds bad. It keeps the change in color found but reduces it if it is not natural. The tricky octave is the middle one, where the balance is difficult to get. In the lower registers there is a lot of harmonics so the result usually is ok as is. In the higher registers, differences in spectrum are less important than the attack itself.

(If Gilles had the opportunity to test the Bosendorfer 200 on Steingraeber with his software, that would be great)

I did consider it but the distance is too great with the Bösendorfer 200, a smaller piano with a much different bass tone, one that is much more like the Steinways.

Re: Modartt strategy

During your short test with Steingraeber, did you use this model directly with its code length of 2.72m compared to the actual Bösendorfer 200 recordings?
(I say that these are raw recordings, but I only use the beginning of each note about 0.7 s for the first octave, dividing by half this duration with each new octave, and using a parallel window 2 times shorter with each new octave (65k then 32k up to 0.512k for the highest notes)
For my part, with the model Bluethner I first reduced the size of the strings to 2m (more exactly 2.1m) before making the comparison, so that the high partial frequencies can remain comparable between the real piano and Pianoteq.
I also avoided using for the partials simple multiples of the fundamental, by aligning me on the frequency of the partial as indicated by pianoteq for each partial in the spectrum profile window. To integrate a few more partials than what Pianoteq presents today in its spectrum profile window, I extrapolated the frequencies of the top partials not presented in the pianoteq window with a polynomial function (trend) by relying on the partial frequencies described by pianoteq. (Pianoteq seems apriori capable of exploiting partials well beyond the limit of the partial No indicated in the spectrum profile window, but on the other hand does not know (today) not manage them with the function of rescaling, which requires to reconstruct either this rescaling function itself) I set myself today a limit of 250 partial and a maximum frequency of 45Khz (that neither my ears nor my scan card from micro can not handle ...). A difficulty is to consider the string stiffness that seems different from one piano model to another, and I guess may be different with Bösendorfer. To adjust the length of strings to use with Pianoteq, I check if the frequencies of partials a bit high (around 8khz) correspond between pianoteq and the real piano for level peaks, and for the rest trust my ears. (Hence my approximation of 2.1m for piano pianoteq compared to the real piano of 2m). This is totally empirical and maybe a wrong approach, I do not really know.

Bruno

Re: Modartt strategy

In addition, here is the position of RODE M5 mics that was used for the capture of Bösendorfer 200 used in my .fxp (the real piano samples have already been put on the site, I only used the first moments, for each note, 'as short as the note was acute)
this is a very approximate XY because I do not have a bar long enough (I have no professional experience of sound recording some piano),

Hello Bruno. My approach is a bit simpler than yours...I merely offer the pianoteq model a different starting point to do its real time modeling. Starting from the closest instrument in sound and size gives better results since so much of the real-time sound generated is not due to the starting spectrum itself and out of reach, as is the attack sound itself. In fact, what I did is a little more complex Steinway B fxp than can be done by hand. Reducing the string length works of course, but it's better if you can avoid it.

Since we seem to have similar background and interests, I suggest you email me (in french) through the user list pianoteq emailer so we don't bother other people less interested in these matters. I'll be happy to go into more details if you want.

Regards,

Gilles
