[BUG] Weird volume level behaviour #19

Closed jatinchowdhury18 closed 2 years ago

jatinchowdhury18 commented 2 years ago

Describe the bug The plugin doesn't produce reliable volume levels (sending the exact same sequence of MIDI notes+velocities multiple times gives different results on the volume of each kick)

Alternating 2 notes that are +-5 octaves apart gives me an output of up to +20dB after +-50 notes sent. Repeating the same note over and over gives me an output of down to -20dB after +-50 notes sent.

This seems to depend a bit on the RES. MODE param, I get more drastic volume differences with it set to the minimum value, and more consistent when I go to values >0.25.

I think this behaviour is just due to phase cancellation happening in "linear" resonance mode.
