See the seller's other items for more.

A look back at the product description: "The MC-303 is an exciting new product that presents new creative approaches to dance music. Dance music, especially techno music, can now be approached creatively by anyone using the MC-303.
All that's required is just to combine any preset sounds and patterns from the huge selection offered, including sounds from vintage analog synthesizers.
Realtime performance capability is emphasized, such as realtime Cutoff and Resonance controls to vary the sound as well as Arpeggio and Groove Quantize for adding a special feel or groove to the song. The self-contained MC-303 can offer a level of performance which has been only available with huge set-ups including turntable, mixer, and various instruments. The MC-303's integrated features provide advanced DJs with another innovative way of creating techno music.

Moog The Source Analog Synth

via this auction

SN 1627

Description via wikipedia: "The Moog Source is a microphonic Z80 microprocessor-controlled analog synthesizer. Manufactured by Moog Music from 1981 to 1985. The Source was Moog's first synthesizer to offer patch memory storage. The design was also the first (and only) Moog synthesizer to feature a flat-panel membrane keyboard to replace the standard buttons, knobs and sliders, along with multitude panel graphics that were very different from anything Moog offered at the time.

In addition to the memory capable of holding 16 presets, the Source features a 37-note keyboard and two VCO’s that can be selected among three waveforms and three octave. Programmed presets can be saved to an audiocassette interface to free up the onboard memory for additional new patches. The 24dB/octave VCF has parameters for keyboard tracking, cutoff frequency, resonance, and envelope amount. There are two ADSR envelope generators that can be set in single or multi trigger modes, one for the VCF and one for the VCA. For modulation, the Source features LFO and sample and hold. The unit also features a rudimentary sequencer."

EDP Gnat Synthesiser

via this auction

"Very rare Electronic Dream Plant (EDP) Gnat Synthesiser, fully working but the case is in a very poor condition (usual cracking) and some of the pots may need a clean. This would be ideal as a donor synth for a good case or to build into a new custom case or for spares (though it is fully functioning so I hope not). Runs from batteries or PSU (neither supplied)."

Also has a 256 pattern, 16 song on board sequencer (exact same as Future Retro's Mobius, sold as a separate rack mount unit). MIDI AND CV, gate, accent in/out. Use with other vintage analog gear as a cv gate to MIDI converter! "
