I am not sure about your question regarding
the "recording" of MIDI data from the O5R/W since it has no keyboard, but in order to configure the module to respond to MIDI data from your sequencer on multiple channels you must utilize the MULTI mode and there you can assign each sound program to its own MIDI channel corresponding to the various tracks of the sequencer. I believe that COMBI mode can be utilized to allow the O5R/W to respond to multiple controllers each transmitting on a different MIDI channel thus providing shared access for live playing situations.

Most of this information is described in the User Manual. If you don't have one, get one and read it; although uninspiring it should be accurate - my X5D documentation is.

I hope this helps. If I have lead you astray at all I'm sure that someone will correct any misconceptions I have conveyed.

Stay after it - you're almost there.
