Ok, I'm a little confused on the whole bass synth thing. I'm in a "band" (term used loosely) and we're thinking of adding Rush's Tom Sawyer to our song list. We have no keyboard player. I was thinking of using a bass synth to play the keyboard parts on my bass (since the keys part is nearly identical to the bass part and there is no concurrent bass part). Is this possible? I was looking at a GT-6B today at GC but since I didn't have a clue what I was doing with it I didn't get too far. What other FX/synths are capable of doing what I'm looking for? Which models can track more than 1 note at a time, for chords or maybe even two handed tapping? What about tracking? I hear a lot of units have trouble tracking and I'm not sure how slow you would need to play to track properly (it's a moderatley fast part).
