Back in the early '80s, this gem let producers burn their own custom drum samples onto EPROM chips, breathing new life into machines like the Oberheim DMX, DX, LinnDrum, and Sequential Drumtraks—perfect for that raw, hip-hop beat era vibe.

It's a compact, rackmount monophonic digital sampler running at 8-bit COMDAC with 64K RAM, capturing up to 32kHz for about two seconds of audio at top speed, ideal for punchy percussion via line or mic inputs with peak metering and sensitivity switches. Edit samples using attack/decay envelopes, reverse playback, ring modulation, stretch/squash, and bit manipulation, then loop, transpose over 12 octaves, or trigger via MIDI with velocity, pressure, zoning, and program changes. Burn 2K-64K EPROMs in COMDAC or linear formats, dump via MIDI SysEx, and control everything from a straightforward front panel with knobs, buttons, and a display.

Vintage enthusiasts love its role in expanding classic drum machines, praising the gritty, lo-fi tones and solid MIDI implementation despite the mono limit—though editing is basic by modern standards, it nails that authentic '84 character.
