• Condition:

  • Museum-Quality Time Capsule: Unused, fully functional unit in its original packaging (produced 1984-1986).

  • Untouched: Ideal for a serious collector or synthesizer museum.

  Overview:

  • The Ultimate Vintage Utility: A highly specialized device designed to burn custom EPROM chips for iconic vintage drum machines like the Oberheim DMX, Sequential Drumtraks, and LinnDrum. Think of this as your Analog Expansion Pack

  • 12-Bit Era Power: If you live or die by your vintage drum machines, this box multiplies your creative power tenfold by allowing you to sample and burn your own custom drum hits.

  Sampling & Sound Character:

  • Engine: 8-bit, monophonic sampler with variable sample rates.

  • Selectable Sample Rates: Choose between 12, 16, 24, or 32kHz (yielding bandwidths of 4.8 to 12.8kHz).

  • Memory / Sample Time: 64K memory providing 5.46, 4.09, 2.73, or 2.04 seconds of sample time depending on the selected rate. Different "blocks" can utilize different sample rates.

  • True Hardware "Bitcrushing": Allows real-time monitoring through the A/D and D/A converters before recording. Doubles as a massive, gritty "analog-style" bitcrusher that modern plugins simply cannot replicate (similar to the Sequential Studio 440).

  Editing & Control:

• Onboard Manipulation: Edit start point and decay time, or apply digital bit manipulation including reverse, stretch/squash, and ring-modulating one sound against another.

• Modern Integration: Send all samples as a MIDI SysEx dump to modern software editors (like WaveLab), edit them on your computer, and send them back to the Prommer to burn your custom EPROMs.

• Connectivity: Controlled via MIDI and Trigger.
