Marion Prosynth

via this auction

"The Marion Systems Pro Synth is the latest in a series of modern instruments attempting to recapture the sound of analogue monosynths, but without their inherent tuning problems and unreliability. Housed in a 1U rackmount, and proudly bearing the name of its creator Tom Oberheim.

The Pro Synth is 8-voice polyphonic with just a stereo output pair, no headphone socket, no effects, and no sampled waveforms. A simple multitimbral implementation allows up to eight different sounds to be driven from their respective MIDI channels"
