Circuitbenders - Mods for Roland SH-101

Fortunately these are DIY mods, and not actual circuit bends.

"The mods consist of:
Filter Overdrive – This knob drives the VCO or external audio source into the filter stage causing the VCF to overdrive and distort. The knob is wired with the maximum drive as fully counter-clockwise and the clean sound filly clockwise. In this respect it could be called a Filter Cleaning control but it is wired this way to give the best response curve to the control. This control will boost the output of the 101 a huge amount so be careful.

PWM waveform source – Normally with the PWM set to LFO modulation you only have the option of using the triangle waveform as a modulation source. This rotary switch allows you to set the PWM modulation source to other waveforms independently of the main LFO setting. The options are Triangle, Square, Random, Noise, Sub-1 and Sub-2. The Sub waveforms are actually sourced from the VCO. Changing the setting of the sub octave switch will alter the sound with these sources.

VCF CV input – This jack socket on the top left of the case will accept an external voltage to control the filter cutoff. The suggested input is 0-5V but it can probably take a couple more volts if your Midi-CV converter can deliver them" and more.

"Not the Yamaha CS80, but almost there. With some more tweaks it can sound even closer."

"short synth demo with some bass and 'blubber-sounds' by RetroSound
The Odyssey can much more it is very versatile (sample and hold, ringmodulation, sync, frequencymodulation and more).

no external effects used, pure Odyssey sound :-)

The ARP Odyssey Model 2821 or Odyssey III is the little brother of the ARP 2600. The sound is different to the moog-sound. A great bass and lead synth."

Hammond Condor

via this auction

"This is the Condor synthesizer made by Hammond in the early 70's. It is very rare and hard to find information on. I read hendrix may have even used one. It has an input for a contact microphone that is for a wind instrument. I do not have the contact mic. The unit powers up and does not appear to have any issues but i cannot test it any further, see the photo for the condition, the only other one i have ever seen sold for almost $400. It has slider controls for vibrato, intensity and rate, treble, bass, sensitivity, tone and volume. It also has organ type switches for repeat, attack ,tremolo/vibrato, sub-octave,dynamute, fuzz,oboe, sitar,natural amplify, sopano sax, tuba, oboe, english horn, cello, clarinet and a few others. There are also some adjustments on the bottom of the synth."

KORG MS50 ANALOG Modular

images via this auction

"1978 built in Japan. It is cool on its own and even crazier coupled with an MS20 or MS10, it was designed as an expander to these, although I’ve read it has a better build quality than the MS10 or 20. Being FULLY Modular it is very versatile and can be used for FX, processing audio and control voltages, etc it even has a great ring modulator. You can process guitars, other instruments, mics, your voice etc. You can create stereo pingponging, tremolo, all sorts. Have a read up on them, good reviews, see sequencer.de.

It is a 240v ac 50/60hz Australian plug end. Serial number 190503

The Korg MS-50 - modular in design and at the height of the MS-series synthesizers. This keyboard-less expander type module is completely patchable and uses Korg's Hz/V type of CV and Gate for control with other synths like the MS-20. There are lots of knobs and patch points on this one... The MS-50 is still a single VCO monophonic analog beast but offered more patch ability and power than any other MS synth. Other features include a ring modulator, voltmeter and sample & hold. It was also designed to complement the SQ-10 sequencer. It has been used by The Chemical Brothers."
