Sorry this is long winded... but

I need to make sequences from combinations that use dual arpeggiators. The directions to do it are on p.66 of the User Manual

I followed it to the letter but when i go to use a combo, it sounds like it is playing double sounds on playback
like everything is on the same MIDI channel
I went into the combo and changed the MIDI channels and it made parts drop out
so it sounds normal when Im recording
but doubled when I play it back

I need figure out how to make the homemade combos stop sounding like everything is playing on every MIDI channel at once ?
