Hello Ien, I got your samples you sent me, for reference: FluidR3 GM2-2-0-52-Ahh Choir.sf2 8bitsf-0-0-PIANO 1.sf2 With the choir instrument, the default release on the global instrument zone is 3 seconds. The velocity of the key being pressed determines the release time of the volume envelope, a

Hi everyone - I'm seeing an odd problem where the synth is not stopping the sound after note off with certain "loud" soundfonts. Specifically, with the standard GM grand piano soundfont, everything works great, notes on and notes off as expected. Switch to a soundfont that has a sharper or fuller
