Roland CMU-800 CompuMusic with Apple II Interface Card

Note this does require an Apple II and software to run. You don't see pics of the card often.
See this post and this post for a couple of video overviews of the CMU-800. A search will bring up previous posts.
"Up for sale is a very rare Roland CMU-800 CompuMusic vintage analog synthesizer/sequencer module. Additionally it has 8 cv/gate outs for controlling other gear that supports this feature.
The unit powers on and the LED lights up, but that is all as far as the testing goes as I don't have the needed gear to test. So I am selling this AS IS.
It also comes with an Apple II interface card -- no software though. (Everything you get is in the two photos).
If you search the net there is a way of making or buying a MIDI interface for this. One is available for around $75 from beatnic.jp, which is based on an atMega168 using schematics and c code another Japanese fellow developed. I'll include on a DVD-ROM this set of files. -- in case you want to implement your own using the schematics, printed circut board image file and the c code.
I read that with the MIDI interface you can trigger all 8 channels of the cv/gate -- for compatible gear. Channel 8 has a nice portamento effect."

Furious Microtemporal Programmer / Sequencer
Published on Aug 30, 2015 Gerald Stevens
"Video showing the basic features of my touch keyboard, ribbon, and joystick controlled analog microtemporal programmer sequencer. It is a little complicated! Lots of Ken Stone CGS boards insides, with a hacked Arduino / Narbotic Midivox MIDI clock.

The microtemporal side (continuously variable note lengths) functions by comparing any analog waveform (a rising sawtooth for the easiest to understand) with 16 stacked, variable width (each knob in the bottom row) windowed comparators. The other useful custom feature is the four gated (i.e. "strobed") LM311 comparators that allow note by note muting across all four sequencer tracks. Really simple (just turn the knob to zero) to implement - probably has been done, but I haven't seen this before."

RITM2 Repair, CV and Gate mod DEMO
Published on Aug 30, 2015 littlem4tt
"I have had this amazing little synth sat under the bed for around 6 years. I used to think it was meant to take 45 mins to warm up lol.
I also wanted add cv and gate to use with eurorack and I found this awesome mod from http://www.modularsynth.ru/en/2013/06...
All synth sounds in this video are from the RITM2, live drums by Dave Knight"

Respectably Insane - Dave Smith Instruments - Sequential Prophet 6
Published on Aug 30, 2015 Paul Johnson
"The weird and wonderful world of the beautiful Prophet 6. Arpeggiated patch at very slow intervals and bpm with the occasional knob-twiddle for good measure. Recorded live in 1 take and the only effects are a touch of built-in chorus and BBD. Video shot separately just after the audio had been recorded, then spliced together."
