Hi Frank

The two midi ports you need are "In" and "Out". I am not sure why you label them "A" and "B". JammerLive would translate chords to accompaniment patterns. Thus function requires that the chords be sent to the computer and the accompaniment be sent to the keyboard (with built-in sounds). The non-accompaniment sounds do not require midi as they rely on local control by the keyboard.

One attraction here is the freedom to select any synth as a controller. Now you can have a Korg Triton arranger, a Kurzweil 2600 arranger, or a Roland XK88 arranger. I might pick the S80 because I could add vocal harmony to it.

However, I agree that not being able to select styles from the controller is a serious limitation. Soundtrek should treat sounds as patches and allow them to be picked with bank and path numbers (to allow up to 16k styles).
