This unit has two banks of 16 stages, and can be configured to trigger 32 stages sequentially. All stages trigger. The clock has been tested to trigger at a continuous range of speed. The oscillator sounds "fat and juicy". The filters (2) have been tested to modulate the signal."
Update via Dave Cornutt in the comments: "The 400 sequencer is actually the leftmost box on top. It was a neat design with a quantizing feature that could be tuned for equal tempered or alternate scales. And by patching the gate signals, it was possible to make it do quasi-random permutating sequences.
The box on the right was the 401 synth. It was a two-oscillator synth with the EML two-pole multimode filter. The synth they are both sitting on top of is the EML 101 semi-modular."

"Bob Weigel of http://sounddoctorin.com goes over the layout of some of the more significant components in the Korg Polysix, a synthesizer which sold around 22,000 units produced from 1981 to 1983 or thereabouts. Korg simplified and cut cost in many ways on these units but they stand as one of the few fully analog (with a discrete VCO for each voice if not two) polyphonic synthesizers ever mass produced along with the Prophet 5/10, the Oberheim OBX, OBXa, and OB8, which had BOTH memory and full editing from the panel without toggling through menus etc. Later a MIDI retrofit was also introduced bringing this unit and a rather nice one I hear. Hopefully I can get mine working that I just purchased broken :-). That unit is not shown in this demo though. The MIDI board lays over the top of the CPU's and a connector actually goes into the cpu sockets and the cpu's set on the new MIDI retro board."
"Portable Analog Modular Volumetric Video Synthesizer-
Patch programmable by 'patch wires', just wire with no cable. Synthesizes a multitude of hologram quality 3D moving images. The smallest synth of the Hologlyphics system.
Inspired by when Synthi-AKS met R2D2 and saw him holographically project Princess Leia."

Featuring (among others) envelope follower, bit crusher, sample rate reduction. Other gear used: Roland PMA-5 (sequencing and crappy piano sound), E-MU e64 (sample drums), Behringer Virtualizer (delay)."
