Thanks for the reply, I think we’re in agreement on the complexity of the problem, I do wonder where the limits of perception play a part, an important factor is the psyschoacoustics, most people can’t even discern pitch variations by a few cents, let alone timbral differences that come from a more perfect physical model. But the reality is there will never be an even approximately perfect model and that’s sort of the beauty of what makes an instrument as a real object. The sound is a complex physical phenomenon that happens when hundreds of coupled harmonic oscillators are in close proximity, which even just naively would be modelled by a nonlinear differential equation with hundreds of terms. I am no expert but do have most of a physics degree (only some shame in dropping out, mostly for health reasons), in some sense the sound is a simple sum of it’s parts, the sound pressure contributed by every part of the piano but also more literally, since a sounded note is approximately periodic and every periodic function can be written as a sum of sinusoidal components, a spectral analysis of a played note will reveal that the timbre is what we perceive as the sum of every partial frequency (harmonic and inharmonic) sounded in response to the hammer and the simple harmonic motion it causes in the string. The attack is transient but the magic is in the fixed parameters, string length, gauge/mass and tension; particularly length is the key, since a string fixed at both ends will reflect waves and cancel all transients to allow only one mode of oscillation, that of standing waves at their natural frequency, the perceived pitch, during the sustain and decay portions. While it is theoretically possible to perfectly reproduce the signal a given ear would receive, the actual synthesis of that signal would be either so computationally complex that there is no hope of realtime playback or would be imperfect, really the sampling concept is probably the best approximation because it erases the necessity of actually solving anything, but captures none of the nuance of articulation, it’s a hard problem and a good one to tackle I wish you luck in optimizing
edit: also about polyphony and samples, there is also the effect of layered noise floor which is not insignificant, for example the vst piano in blue by cinesamples has noticable hiss when you play many notes that doesn’t decay, because of the recording, an obviously non-piano imperfection introduced by sampling. Still I play it because it’s a sample of the exact piano bill evans played on kind of blue and is that not just a bit a fun.

By jove we’re already at terabyte scale pianos
Yeah 10 seconds is a bit much, I’m still impressed at how well convolution works as a concept and that’s with ~300ms samples. I’ve actually been eyeing your convolver in the app store it looks great! just I have impulsation already (and a limited app budget). I’ve got make louder and think I’ll buy the JAF collection someday as I like to support devs and appreciate the communication, I can tell by this thread it’s not always easy lmao
Actually a very interesting thread I saw in a bitwig forum might be relevant to your sound buffer problem, at least with multicore ipads, and is a good read and funny example of the (un)pleasant way forums can be ( https://bitwish.top/t/idea-for-better-multicore-cpu-support/3633 )
Saying "interesting thought" to someone else's comment is "stabbing you in the back"?
I have no idea how many names you go under on the forum Jens, HAL, Jason. The thought that you might have another is not so far fetched.
Interesting that you attack me and not the person who made the original suggestion.
If I wrote this about you, you would be freaking out, crying and complaining.
You complain about people making nasty comments about developers and you make these kinds of comments. You are nothing but a hypocrite.
.
Interesting thought
😂
No , I’m Przemysław Szczypek from Poland and my face in 2005 was like this:
Is that meant to be some kind of threat?
LOL.
Note that the Yamaha digital pianos used in this performance are not generating the sound but rather controlling instances of Pianoteq. Not sure that the Yamaha S90 can even do microtonal itself. In any case, I own and enjoy Superior Grand and its responsiveness to midi velocity in particular.
I had the same question but I found the answer regarding Pianoteq in the YouTube comments section.
impresive! both sound and viaualisation, allow for listening, learning, inspiring… I think it is intetresting project, especially because included library and possibility to view zoom keyboard, with deep sound. and nice example of soft played jax grand sound.
The performance (of great player in mid file) is incredible, thank you. I love this kind of old jazz piano tunes. Will be great new app with concert grands and included midifiles!
That’s a great piano sound for the rhythm part and a nice crisp, chimney piano sound for the melodic player.
Is it being rendered with 2 target pianos?
There's a wonderful range of tones in there. Looking forward to picking the "Imperior Collection" up when available.
Are they ALL dropping at once or one at a time? I have credits right now from a gift card.
Very good News!
I tried it at first on my MBP but I couldn’t make it work in GB.
On my iPad it is working perfectly but is a bit taxing . Depending on what I play especially with the sustain pedal.
Overall, I think this piano is too clean, wide and bright for my work, even when playing with the parameters.
For my solo piano music it is perfectly usable, it works well with my keyboards, but it is a shame I have to make this beautiful clean piano dirty to fit my taste. It is at the same time quite realistic and very playable, but since it is a modeled instrument, something I would not « complain » with a sample piano: the lack of transmission of strings resonances, the way low strings vibrations propagate to the next strings and the octave strings, is a bit missing here. It is really nitpicking and would probably kill my iPad though. Maybe it is there but I can’t really ear it.
So, beautiful sound, no phasing at all, good for my usage in solo piano after I make it dirty. It really is impressive. I still prefer my own piano samples because I made them and because of of the overall sound I tailored for my usage, but if this technology could produce the kind of sound I like, and I had a more powerful iPad, I would just abandon sampled pianos. I especially like how it does not sound like from the player perspective but from the audience perspective.
Now in my case, my iPad is not powerful enough to run it in a full instrumental composition. It is making weird noises like violent static bursts. And it is super cumbersome to simulate track freeze in NS2 so I can’t really use it for now.
Nice update… I like the new pianos and find them useful for listening to MIDI recordings of
Scott Joplin and Bill Evans which covers 2 significant eras of “Jazz”. The UI is also improved as I recall… it’s larger on my iPad Pro I think.
I’ll purchase it… but post a promo here for someone with out the funds to enjoy your work.
Maybe mail it to @LinearLineman and ask for his input. He has hated a lot of apps and later decided he was a bit hasty.
I do think your app still needs “user feedback” on some issues but I know you’ll address anything that you can re-produce. I always give a developer that time to address bugs before advising someone to pass on it. There’s too many examples of apps that needed time to shake out those pesky bugs.
Software always has bugs and I’d hate to see you stop communicating here because I can tell you are eager to please your customers.
I have all 3! But to be honest I haven’t connected my iPad to the Casio because I just keep
Glueing apps together in AUM on the couch. I tend to use the screen keyboards. But I collect Piano apps and keep finding free ones on PianoBook. Anyway… keep ‘em coming.
I’ll try and give your apps a fair test drive on my Casio P560 and wish I had something better like a Kawai, high end Roland, Yamaha or Nord. Maybe an Osmoze to add expressive MPE Pads to your pianos in AUM.
Working keyboard players are always mixing in strings and pads with their piano.
Check out the videos for “Worship Pads”. You could do well there with your programming skills.
But you seem to be a lover of historical piano literature and performance. Nice but they are a picky lot.
If you can make these guys happy:

I have an 8th gen and a 9th gen. Nowhere near the power of the m1
Wow!
I know. I wish more keyboard players had the chance to use a real piano. Those things are huge and not cheap though. But piano lessons with a real piano are affordable. And they don’t need to put their fingers on a CF6 to get enlightened about what a piano is.
I tried tweaking, but it is a bit too bright.
I get what your app does, for different genre I would happily play it.
For now, With very heavy compression, detuning and EQ I get closer to the sound I like, but it kills the precision of the dynamic, creating uneven sound level, and it of course also kills some of the « life» of the piano.
I recorded this on an old Erard, that should give you an idea of the kind of piano sound I really like. (Even if I’m not super happy with the mics I used) https://forum.audiob.us/discussion/52685/some-piano-solo#latest
funny quote from > @McD said:
I have no issue with the dynamics of your piano : it is simply lovely and near perfection. I got actually so used to play my samples when I don’t have access to a piano like right now in California, that your piano feels like having too much dynamics !
I don’t like pianoteq. I totally understand this kind of simulation is incredibly hard to achieve and would require insane processing power.
Be assured I will try it.
Thank you so much. I really appreciate.
Thank you 🙏. Replacing some of my custom piano patches with a simulation I can set up to my liking would be a great improvement for my piano solo music when I can’t technically record a real piano.
I think for most of these “real instrument” apps we simply want something that the listener cannot detect as “fake”.
For example, some people like “Sensual Sax” as a good sax recording… and for me it’s a musician I’d never let play on a track
Because the “raunchy” tone of the samples just turns me off.
For some reason, Donald Fagen of Steely Dan who used many guitar studio musicians to get a solo of Kid Charlemagne decided to play a super cheesy sax from his Digital Workstation on an album… go figure.
We bring a world of baggage into this evaluation of IOS apps… as a player, as a producer and as a listener.
But technical details of “hung notes”, audio distortion, or obvious midi dropouts can kill a poorly designed app like some of the
$2-3 SoundFont players even when loaded with the excellent Salamander SF2 instrument… (excellent in the view of ABF forum
Member in a 3 week poll conducted). That poll used one MIDI file that had a millions notes played very loudly: the Grieg Piano Concerto (sans orchestra).
“Bed room” producers… I work exclusively in the living room. (Still need that humor/sarcasm font).
No one mentioned the quality of the sample envelopes when Grieg is coming at you at 0dBM.
By damaged do you mean:
Bad audio editing of the sample?
Distortion in the recording process with a hot mic?
“Salamander” seems to have been replaced by a “C5 Piano” set at “soundfiles4u”. It shares SF2 packages and
I think that format does not expose the samples for reuse and I’d need to open the package in Polyphone on a Mac.
Then I could inspect the attack portion of the signal… I can’t confess to hearing anything but all these products sound like
“Recordings” of a piano coming from speakers… even a bad upright has qualities I admire in a musical experience.
To me a piano is like person… there’s that first impression and with enough dating you start to get bored or see imperfections
That set you off looking for a new experience.
Still… apps under $10 always get a date with me
because the drama of dating is addictive.
Education is helpful… I het your point here. In terms of signal those sympathetic components do multiply but they are not obvious compared to the fundamental “oscillation” that is produced as the pitch. If each occurance of these extra frequencies start to overtake the pitch then everyone might detect the final result as destroyed.
Still… it’s easy to slip into audiophile engineering speak that’s illustrated with graphs and waveforms when most of us simply
Throw a MIDI note at an app and are either pleased or displeased. Then we throw more notes and continue to evaluate if we have buyer’s remorse.
I know here are people with better “ears” than me but I enjoy music with the equipment god gave me and wonder what it must be like to be a Jacob Collier that can hear minute variations of pitch and produce them with his own voice in layered acapella performances. Still… my wife prefers my singing voice. Silly woman.
I use samples based piano patches when I have no choice. I Taylor each patch for the specific music it will play (I was mucky to have the opportunity to sample 3 different pianos). Like with any other instrument imitation I’m using, I try to take advantage of the limitations of this technology. And especially not playing what it can’t play convincingly enough for my ears.
It is especially important with the piano. I never really liked any of the commercial options.
Your piano would make my life much easier and use less storage.
Updated the app.
First impression: is that you? But…. Different colour of hairs, and new clothes…. But still yes, ❤️ it’s you.
Different yes, but still the same inside source.
I tamed brighten, tweaked a little, but how long should I tweak if I just love to play with it? Just shorter tweaking it’s better, because more time to just playing and fascinating the sound, the music.
Every update this superior grand sounds differently, and I love it.
I love that dev is listening, trying, the product have its own life, and I totally accept this changes, supprises are great welcome, not boring. Im sure on the other side of app, from the code side is human which have own experience, feelings, and brain.
Too much forum can be problematic for any of us. It’s more about playing music than reading - even if I read forum a few times a day.
I understand dev trying to bring changes what “customers” asked for. But I liked oryginal superior, updated superior, and now this new carnation of superior. With open to next and next changes if dev wish for, because it’s unique experience each time when I play on this instrument.
This cannot compare to nothing like sampled Yamaha or salamander and any from DS is not even in half/half (25%) as good as superior grand. I deleted them all, not seeing anymore in this direction. Too much dynamics? What a problem to adjust a velocity curve? Sure, if somebody need to see “a problem” then there will be a problem.
For me, there is no problem at all, even if something is different than I expected, because I’m open to changes, able to tweak fast, immerse on music, fast forget about models, knobs, ui. Yes I hear this new resonance in high, but tweaked balance timbre and more parameters. Developer also heard and said, so product will change, envolve , I trust to dev , and I liked oryginal “dull” body, and next one, and this “too bright”. My voice is not for sweeting dev. And not because I like to be in opposition.
No. I said that’s all because I hear, see and feel THE JOURNEY with the piano sound app. It’s not easy journey, but exciting. Sure dev could travel alone, without us, without me. But I really like to be there, to experience all of this changes in the app. Little troubles here and here, but what a benefit! It’s like exercises on gym, if you do this properly, the strong will be on your side. If too serious, injury only. Bravo for JAX for this new shape of superior and we are happy to see you work on this hard.
EDIT; I like this current high bright sound (tweaked to tame), after 30 minutes totally forgot that there was an update. The parameters range is huge palette so anybody should be able to achieve what he wants.
