"Listed as 'modular' - but it's a semi-modular, 4-voice paraphonic synth, or mono synth, with on-board effects (reverb, delays, phaser, flanger, chorus), internal sequencer and interpolator (innovative design where sequencing can combine morphing of the oscillators, filter, LFO and envelopes), with patch memories. Very useful multi-mode filter (LP, BP, HP), with digital and analogue filter circuits. Good connectivity including midi (front and rear) for this to be the centre of your modular universe.....and it sounds wonderful and is built like a tank. Version 2 firmware with version 1 livery. This is the more expensive desktop version which can be rehoused in a eurorack case by simply disconnecting from the internal power bus and removing from the case. The case does however provide benefits for connectivity, e.g., the 1/4 inch jack inputs to run any external signal (mono or stereo) via the effects section. A future classic?"

"This is a unique opportunity to buy a monster synth, that is also a piece of synth pop history. Two cabinets plus the original keyboard, all lids, interconnection cables and original manual included. The first cabinet is a Roland System-700 Lab is one of the rarest and most sought-after modular synthesizers ever built. Introduced in 1976 as part of Roland’s legendary System-700 series, the Lab version was designed as a compact, self-contained modular laboratory for advanced sound design, research, and education — but with the same discrete analog circuitry, massive sound, and build quality as the full studio system.

This one was owned by Bill Vorn, keyboardist of the synth-pop band Rational Youth, used in the following albums dated 1981 to 1983 : Rational Youth, Saturdays in Silesia, City of Night and I want to see the light, as reported in the certification signed by Bill Vorn himself, provided in the item. The second one is another original SYS 700 one, connected and internally cabled to the main one by means of the original cable, with the super rare modules that you see in the picture: an additional, multimode filter, the great output module and… a professionally custom module with a perfect ARP 2600 VCF clone… plus other stuff.

All the best Sys 700 modules, featuring the iconic vintage Roland tone — warm and incredibly dynamic — and offers an extraordinary range of sonic possibilities thanks to its flexible patch architecture. Perfect for collectors, professional studios, or synth enthusiasts looking for a centerpiece instrument with historical and musical significance. The system sports a comprehensive modular architecture with 3 oscillators, 2 filters, 2 VCAs, 6 envelopes (!), mixer, phaser, spring reverb (HUGE) and …utilities.

Legendary System-700 sound — powerful basses, evolving textures, experimental tones. What to say more? Fully functional and in very good cosmetic condition with minor signs of use. You will never find another in such condition. Last call…"

"PPG - Waveterm B (s/n 0157). In good condition (very good apart from some rust on the black keyboard 'shelf'). It powers up and screen shows “PPG Wave-Term B”, but not tested further as no system disk. It might be unlikely for the disk drives still to be functional - but they can be serviced, we think, if needed. VEMIA can collect and pack: 30GBP."
