Re: [fluid-dev] repeating a note with the sustain pedal active cuts off the previous note

Hi, Christian

Please, could you try the branch named "pedals" to see if it works as expected when sostenuto or sustain pedal is active.

See https://github.com/FluidSynth/fluidsynth/pull/905.

Thanks.

After a bit of experimentation, I discovered what the problem is: when playing the same note more than once with the sustain pedal active, the previous note gets cut off. This is especially noticeable if you play the note loudly and then softly; the loud note just abruptly disappears. This did not happen in the past when I was using an older FluidSynth version for live performance with my band.

1. Real keyboard instruments do not behave in this manner. With the sustain pedal depressed on a real piano, if you play a note loudly and then very quietly, you still hear the continued vibrations from the initial, loud keystroke.
2. All other MIDI GM-style devices I have encountered allow previous notes on the same pitch to remain, including those by Roland, Creative Labs/E-MU, and every other SF2 and SFZ sample player of any worth. AFAIK, FluidSynth stands alone in the decision to mute older notes on the same pitch by default.

3. FluidSynth after commit #048c51 (pedal notes-FluidSynth-new.mp3)

3. FF note followed by four notes increasing in velocity from PP, and then repeating a few times.
