Explore this buying guide ↗Why consider this model?
- A source-based option for a 49-key USB/DIN controller with 12 velocity curves, fixed-velocity entry and AA-battery or optional-adaptor power, but without the A-500PRO's pad bank and larger assignable surface.
Tradeoffs to weigh
- The A-500S is discontinued and its official driver list targets legacy systems; compatibility with a current computer must be verified rather than assumed. It has no documented pads, key aftertouch or MIDI IN, and the old software bundle is not a current license promise.
