"Designed by Tim Orr for 'EMS', this remarkable D-battery powered synthesizer comes in its original briefcase format. Most experts approximate that less than 200 of these units were made, largely for educational institutions.

Case measures 18" wide x 14" tall x 5" deep (approx. 45.5cm x 35.5cm x 12.5cm).

It's not our area of expertise, but here are the features we've managed to identify:

*Input Amplifier with low (Microphone) and high (line) level inputs.

*Envelope Follower, providing a voltage proportional to the amplitude of the input.

*Oscillator 1, with true exponential voltage control of frequency and three simultaneous output waveforms (sine, triangle and voltage controlled pulse).

*Oscillator 2 for slow control voltages such as glissando or vibrato.

*Filter/Oscillator 3, with v.c. low, high and band pass filter or pure sine wave.

*A Modulator for envelope shaping or ring modulation.

*A Noise Generator.

*Trapezoid Generator, for multiple simultaneous trapezoid waveforms. These may be used for envelope shaping (trigger mode) or for low frequency waveforms (free run mode).

*Manual-Slide tape Controllers (x2), for obtaining control voltages. One slide-tape is stepped and looks to be used as a keyboard, and the other for variable control. One is said to provide a trigger pulse.

*An Inverter to invert control voltages or signals.

*A Monitor Amplifier and Loudspeaker, with two input mixer faders.

Comes 10 original patch cables and a 1/4" jack plug. Also presented with its original lock key..."

Frank Eventoff Sonica SN 227 Video

Note: links to listings are affiliate links for which the site may be compensated. Sonica- late '70's primitive synth

Published on Apr 11, 2013 Derek See

"Made in L.A in 1979; kinda theremin, kinda magical musical thing..."

I believe this is the first video of the Sonica posted on the site.  It's much smaller than I expected!  I've posted a ton of these and I don't think I ever realized just how small it is.

"Super cool primitive synth, made in Los Angeles by Frank Eventoff in 1979. This one is #227 out of (allegedly) 650. Very clean with all original paperwork in the custom chipboard case. The center tone knob is not functioning, but all else works great. See it in action here:" [embed above]

DOEPFER POCKET FADER SN 221417

Note: links to listings are affiliate links for which the site may be compensated.
via this auction

"16 fader MIDI controller. 128 presets selectable via the DIP switches on the back or by program change message over MIDI...

the following Midi messages can be generated:
any controller, after touch, pitch bend, common RPN resp. NRPN controller, as well as most of the current GS and XG controllers resp. XG SysEx messages

the MIDI channel can be set for each control separately (of course all knobs may transmit on the same channel too, any combinations of MIDI message and MIDI channel are possible)

the editor program (PC version) enables the user to program his own 128 presets. This means that you can define the function of each of the 16 controllers in your own 128 presets. You no longer depend on the factory presets ! The program can be downloaded free of charge from our internet site - e.g. to test the programming possibilities before you purchase the Pocket Control"

Original Roland SH-3 with Kenton CV Mods

Note: links to listings are affiliate links for which the site may be compensated.
via this auction

"In excellent condition and 100% working order.
As you can see from pictures very clean, a couple of small scratches here and there, has the Kenton 3 socket gate/cv/filter installed. With a midi to cv converter like the Pro Solo you can control the cv/gate and filter of the synth. Has been overhauled, all capacitors replaced, all sliders pots and switches cleaned and re-lubricated, plays wonderfully..."

Update: The auction mentions the SH-3 had the Moog ladder filter. It actually did not. Via wikipedia & Keith Kniveton on Facebook: "Contrary to common belief, the initial version "SH-3" did not infringe on the transistor ladder-filter patent of Robert Moog. It used a diode filter like the EMS VCS3. The SH-3a does use a transistor ladder-filter and as a result can generate Moog-like sounds.  [edit]"  Also see this post.

"The synth has the Kenton 3 socket kit installed. You can controlled filter, and cv/gate from your DAW/sequencer. The synth has had a complete overhal, all capacitors were replaced, very high quality parts were used and some audio grade caps on the signal path. Sound is amazing. Everything has been tested and works 100%."
