Howdy Ian,

You should be able to set up your devices for play-along as well as recording. Please do be aware that setting up multiple MIDI devices for specific input and output can be a bit, um, picky, so you'll have to pay close attention to details for initially setting things up. Did you work through the section in the Users Guide for setting up input and output devices? Is there a particular step(s) that is unclear? If so, do let us know what steps you've tried, and what is (or is not) happening.

ttfn,
Sherry

p.s. By "NS search", I'm presuming you mean using the Index in the Users Guide. You're right - "through channel" doesn't appear in the index, as we've tried to keep the terms we use in the documentation rather "musician/notation" friendly, rather than using sequencer terminology. You will find "MIDI device", though, and a whole slew of subtopics.
