Re: [fluid-dev] MIDI piano + sustain pedal realism

I you wish to get this sound shape effect  you have to add this yourself by adding instructions in the soundfont (as proposzd by Tom's answer).

What you hear from a real piano after doing an immediat release-depress is the natural resonnant of the most recent notes being free to decay slowly.

This is a default behaviour for piano. This is not a default behaviour for many others instruments without large body. So it couldn't be the default behaviour

of the sound engine of a sf2 syntesizer.

However any sound designer is free to add custom real time sound shape by described this in the soundfont. for sf2 soundfont theses description

have to be made via the concept of "modulators".

I you wish to get this "decay" effect (after immediate sustain pedal depresse) you have to add this yourself by adding  in the soundfont (as proposed by Tom's answer).

I feel you should add a modulator with CC 64 (sustain) on input and Release generator on output. The amount of modulator must be adjusted to augment the release time to the value

proposed for the "decay time generator".

But it also appears that the current behavior of FluidSynth conforms to the SF2 spec, so probably no hope to change that either. What I've been doing is converting the SF2 files to SFZ with Polyphone (polyphone-soundfonts.com/en/download), and running those in LinuxSampler. This gives me the very realistic sustain pedal behavior I prefer.
