Frequently Asked Questions

No, the 501B is an expansion module and requires the 501 to function; it’s not a standalone device.
It blends the gate transitions, creating a more legato feel – a subtle softening of the rhythmic edges rather than a drastic timing change.
It’s really targeted at existing ADDAC 501 users who want to expand its capabilities, not a good starting point for someone unfamiliar with the system.
