SX600 - I'm working on a piece where I have two instruments in the right parts, but I want to play a bass solo guitar in the LEFT region. But it plays the guitar sound only in the middle octave and I want it to play an octave lower. If I click on the octave up/down keys, it adjusts the RIGHT parts ok, but not the LEFT. It's driving me nuts trying to find a way to lower an octave the LEFT part - any ideas anyone?
