Likely the VST is interpreting pedal ons/ offs differently than biab is transmitting them.
Pedal messages are controller 64 and a data value of higher than 64 means pedal on and lower than that is pedal off. But some VST consider lower than 64 to be “partially” on to simulate someone partially pressing the sustain pedal. Perhaps there is a setting in the VST to not do this.

Please provide the name of an example demo song in biab that illustrates the problem.


Have Fun!
