I'm not an LE user, I have 8.5 Pro but I was looking for info on the LE products when I spotted your thread.
The Korg is inputing in OMNI mode and triggering the other track, Change that tracks input to something else other than the Korgs MIDI input. Or select a none OMNI channel other than 10?
That set up is a great way to record the midi patterns out of the Korg.
there sure isn't much info about which version of LE comes with certain Roland products.
Anybody here buy a Roland A 49 controller lately?
