on a synth with just pulse wave, use a PW ratio of 1/8 ( 31 on a 0-127 range )
corresponding to the typical missing harmonic of the hammer striking point
on a synth with FM, use a frequency ratio of 1:3 ( 19.02 semitones )
if you have a second carrier, use an additional ratio of 2:1 (1:0.5)
on Blofeld and Q, use Alt wave 1, I think the piano starts ( or stops) at table index 48,
not sure, cant test right now
in general, use a 4 pole or 3 pole LP cutoff at ~ 1.4 k, corresponding to an idealized
piano soundboard impulse response spectral envelope, use a little but not too much resonance
( this depends on the implementaion / scaling of the resonance so I cant give a value here )
you can use *inverse* velo scaling of the resonsce )
if you have two reverbs, use the shortest you can have together with a medium or large room / chamber / small hall
alternativly use a very short delay or low tuned comb filter or static flanger for the first
use some chorus, and panning with keyboardscaling per voice
use dual unison, detuned with a beating of 0.2 hertz, not needed with wavetables, just detune two osc's
velocity and envelope long on filter cutoff, slight on fm index, velo slight on detuning
minimal short 3rd env to pitch one of the osc's slightly up on attack fro 1 - 3 wave cycles
keyboard scaling on fm index (important), slightly on cutoff
if you have yet an other fm carrier pair, tune one osc on the 11th to 15th harmonic,
the other on base pitch or 1-2 octaves higher, slightly detuned, fm index and volume scaled by velocity
or use an additional band pass if available, around that range, level by velocity
if you still have an additional comb filter, you can filter out the 7th or 8th harmonic,
( corresponding to a pitch difference of 33 semitone 68 cents, or 36 semitones respectively )
scaled by velocity ( feedforward negative comb, no feedback )
keyboard scaling on envelope decay times, shorter for high notes of course
amp envelope is the last thing you apply, start with a brick/organ envelope for the amp
if you have a two stage decay, you can use that on the amp ( not on the filter ) and
also on fm index, not on wavetable index
( happens on real pianos too, but also happens with the detune ratio a gave above )
other than said above you can get a useful piano sound with the fm or the alt wave above,
not so much with the pulse wave though
and piano on a modular doesnt make so much sense since even large modulars tend to be monophonic
so possibly that was a joke, wasted
the FM creates pretty much the spectral envelope of a piano, and the typical FM ripples
in the spectrum resemble somewhat those in the pianos soundboard too
I am too lazy now but maybe Ill give sound examples tomorrow or so, have everything disconnected
and in a mess right now
