Hi again .-)

I did some further research on the issue (running PitchFactor in stereo-in / stereo out mode):

The only affected effects are Octaver and HarPeggiator.

While the Octaver switches from mono to out-of-Phase randomly, the HarPeggiator always is out-of-Phase…

BUT: Only Pitch B is affected (Octaver and HarPeggiator), Pitch A is always mono i.e. one side of Stereo Image…

Any suggestions?
