My SD4 got RUINED by the last ROM update, and it is ONLY with BIAB. Ketron was ZERO help. I did find a workaround using a different MIDI in port for recording, but it was not just out of sync... it was STUTTERING with a horrendous noise. Was told not to rollback. I switched to the SD1000 which doesn't have that problem and now use my SD4 for just live performance.

Great sounds... best in the biz, but a small Italian company is not what one looks to for support, especially if it only affects one program (even if it is the best program in the universe.)
