Hi, I use FM8 to play DX e-pianos in GigPerformer & Reaper. I noticed that sometimes, the sustain pedal happened to turn off. At first, I thought that it could be a hardware problem. Later, I noticed that when I played a layered patch, the other instruments still have sustain on, while FM8 doesn't. Then I turned on the MIDI monitor and when that bug happened there wasn't any CC 64 off message.
