Sorry, forgot to mention. I'm talking about Power Tracks Pro Audio. Normally, a track has an assigned MIDI channel but it might be just for output. In Cakewalk, if you set a track to OMNI, it records all the incoming data to that track even if it's more than one channel. In Power Tracks, a channel can be assigned to MIDI channel 0 and I wonder why you would do this. If you want to record some guitars, you need to record more than one channel on a track. In my case, I want to record the output from an arranger keyboard and study the data. It can output on more than 1 channel at the time. Maybe Power Tracks can do it but it's not mentioned in the manual. Thanks for any help.
