Yes, the GI-10 can be configured to send MIDI out on one channel or 6 channels (one per string). I use a GI-10 w/ a GK-2 and I've always had it configured to send on one channel. If you got a used GI-10 w/ a GK-2 for $100 that's a serious score ! I paid $100 for the GI-10 used alone, without a pickup or cable.

Don't stress about it too much, just set it on one channel and record into a MIDI track. Hopefully you have a manual for the GI-10, if not post an email address, and I'll send you a copy.

Personally I find it much easier to create the backing tracks in BIAB and export them into another sequencer (I've used Cubase SX and Logic Express, as well as GarageBand). Then record the MIDI melody onto a single channel track there. Right now the Mac version of BIAB is lacking in MIDI editing capabilities. Hopefully that will change soon, but you will probably find it easier to record and edit the MIDI in another program.

Hopefully this helps.
