It's a REALTIME process, nothing like a 'Chord Track' that some other arrangers have/had.

Basically, play the intro, hit the CS Record button, and play the head. Then hit the CS Play button, and ONLY the NTA ( the notes to arranger) get sent to the arranger (or fills and Vars if you want, but it's better if you don't, IMO) and the arranger plays those chords around and around for you, until you hit CS Stop, which doesn't stop the arranger, just the chord input, and you go back to playing. Maybe a bridge, or a vamp, or whatever, then hit CS Play again, and you are back in the head, or hit CS Record again, and do another section to repeat.

As the chords get played, you are free to do anything the arranger can do. Change Vars, play fills. Do Break/Fills, change styles, even.

In the meantime, while it is playing, BOTH your hands are free to do whatever you want.

It's a game changer, live...

And yes, you COULD save the Chord Sequence, and recall it later, but unless someone follows my advice and adds some more features, it wasn't that great, because you couldn't edit it. Make a flub, and you have to record the entire head again. Chord Tracks are a better tool for offline composing, unless your chops are up there. Mind you, nothing to stop you recording the CS at a much slowed down tempo, and getting it spot on, then speeding up later...
