If I understand you, you have two channels and two instances of EFFECTRIX
I just checked out Effectrix, does it effect a single channel you send to it or can you send more than one channel to it?

So, from pattern 1 ive assigned Drums, Clap + Snare to mixer 5 and added EFFECTRIX to one of
the FX Slots .. Sounds cool .. .. ..

Should it not say ".....Snare to mixer channel 5 " ?

Maybe you just cant open more than one EFFECTRIX    sounds very restrictive but it could be.....
