At some FM-OP frequencies like 429Hz as in the included patch, when the tune knob is lowered to another octave, a plucking sound occurs. Switching to octave 1 or 2 while FM-OP is at ratio 1 or 260.5 Hz produces a similar effect. With the feedback at 100% the unintended plucks can reverberate for a long time. Altering the input frequency seems to clear things somehow.
