SHEET MUSIC PRINTING

What you would like to do is not very clear to me...

They probably mean: improvising, recording, transforming into a score

Using programs like Melodyne, it is possible to start from the audio to obtain the pitches, but then the score practically has to be rewritten starting from the draft provided by the program; otherwise, connect a MIDI keyboard to a PC, play, and create a score (always to be re-verified) from the MIDI

Of course, Modale, it requires a bit of familiarity with these computer tools.

Exactly what Disirae says: "improvise, record, transform into a score", all using a normal acoustic grand piano!

I exclude the idea of using a MIDI keyboard.

I have heard rumors about the existence of the "Silent MIDI" system which, among the other opportunities it offers, also includes the possibility of inserting a MIDI contact strip under the piano keys that sends the signal to a PC. As far as I know, the companies that sell and install such a product do not offer the option of mounting exclusively the MIDI contact strip under the keys. These companies install the entire Silent system, which in addition to being expensive (about 2500 euros) is above all invasive for the piano.......many users have complained after the installation.

I would like to know if there is the possibility for some company to mount exclusively the MIDI contact strip.

Ok... Everything is correct, but there are a good amount of issues to consider. If you want to record in MIDI (via keyboard or by connecting the PC to the silent system installed on the acoustic piano), you must play to a metronome using a pre-quantization setting on the incoming MIDI sequencer, which positions the MIDI event according to a grid (chosen during the quantization phase: for example, a sixteenth-note grid). The grid must be set according to the minimum musical value you intend to play, in order to obtain a properly written score. If you do not respect these constraints, the only thing you will find in the score are notes positioned randomly relative to the timeline. In short, during an improvisation, it doesn't seem very simple to respect all these things. In any case, if this is your goal, I recommend using a digital keyboard; it costs less and works perfectly for what you need.

If you start from an audio file, the matter is even more complex and would not work well. As you have already been told, there are software like Melodyne that perform fast Fourier transforms to carry out spectral analysis and derive the fundamentals of the recorded notes. The problem is that this works as long as the polyphony is sparse enough. In a piano context where you would probably have polyphony (I am only talking about harmonic textures) that with the sustain pedal easily reaches 15/20 simultaneous notes, Melodyne cannot recognize everything. MIDI is without a doubt the best choice. If you cannot play to a metronome, by recording MIDI you can still rearrange the events in post-production. A lot of work, but feasible!

I hope my input has been helpful; if you have any other doubts, do not hesitate to ask.

@Modale, regarding the Silent discussion, I'm dusting off this topic

I quote TheSimon.

One thing that perhaps seems obvious, no program will be able to provide you with the correct division of notes between the hands, so... however perfect the resulting score may be (from the point of view of notes and rhythm), it will have to be reworked. Furthermore, dynamic markings will still need to be indicated manually, even if the MIDI contains this information as time progresses.
