Having only 8 pattern sections per line is kind of restricting in a long piece with lots of chord changes. I spent a lot of time erasing patterns to be able to get all of them programmed. The 8 x 7 grid is kind of restrictive. I know there is an interface issue, but maybe it could scroll. Also, if you could play the entire pad at once, it would be very helpful.
It can play the entire pad, select them all and hit play or DAW sync the lot!
