"One of the most collectible Electro Harmonix instruments, the SUPER REPLAY is offered here by the original owner, complete with DRUM TRIGGER PAD, original boxes and documentation... Briefly manufactured in the 1980s, the SUPER REPLAY remains one of the rarest and most unique digital samplers ever made. The user can sample sounds and music, replay, change pitch, mix, overdub, and loop. Replay with the External Drum Pad or use MIDI to trigger sounds."
via Jason: "The EH Super Replay responds to CV control through a DIN socket on the side. Everyone assumes it is MIDI, but I've done some incredible things with one of these coupled to an MC-202. They are well worth the money, and are terribly unique. They do have a lot grit, but you can sample, then drive the pitch around using a CV which can result in some very heavy lo-bit grit. If I remember correctly, the bit rate changes with the sampling speed, and short samples actually sound pretty clean.
The pinout for the connector is listed in the manual, and provides +5V CV control over Pitch (2 octave range), trigger+dynamics (vca), or gate."
