Happy New Year everyone.
I thought I'd start the new year with an interesting experiment...modeling an acoustic piano. Can anyone point me towards a good starting point?
Karplus-Strong?
Any clues how Pianoteq does it?

yes - but you will at least need an additional allpass in the feedback loop of the delayline to get the inharmonicity of stiff strings:joshb wrote:Karplus-Strong?

and you probably want to model sympathetic resonance, i.e. a mutual cross-excitation of all the individual strings. i guess that implies to actually run the delaylines for all strings at all times making it essentially a giant feedback delay network, but i'm really just guessing

Could be an interesting project. Maybe stick it on github after

Pianoteq uses much more than K-S... Lots of equation solving in realtime, possibly a crossbreed between waveguides and additive synthesis as well...

You've got a number of things to model: the strings, including the initial strike, sympathetic resonance and reverb, the damper, etc. Then, if you want, I suppose you could use samples for the sounds of the hammers, the pedals, etc. There's quite a bit going on under the hood. The latest Pianoteq seems to go overboard at this--I find it overly muddy and noisy. Sampled pianos seem to be more clear and open sounding, at this point, although limited in adjustability.
I started on Logic 5 with a PowerBook G4 550Mhz. I now have a MacBook Air M1 and it's ~165x faster! So, why is my music not proportionally better?

Latest Pianoteq is absolutely not going overboard... you can reduce the noise volumes if you find it noisy (I don't).

I've just listened to the new demos, I haven't futzed with the new plugin yet, but I still didn't care that much for the previous version. Somewhere between Pianoteq and True Piano lies modeled piano Nirvana for me.
