POLIVOKS Soviet Analog Synth
images via this auction.
"Great sound. Very fat lows, crystall mids, icy highs. Very good for agressive bass, weird modulations, cool FXs & agressive sounds. Impressive fat saw & cool glidings. Killer 2-Voice mode.
Modulator section is a low frequency oscillator with multiple waveforms and changable rate. LFO roots to amplifier, filter, VCO-1, VCO-2. Polivoks can play like a classic monophonic synth or in 2-voice mode. And also You can modulate VCO-1 with VCO-2 (ringmodulator).
No pitchbend & modulation wheel.
There is a custom made CV/gate modification on the board (1 voice).
Now You can connect analog sequencer (1 volt per octave)
This is very usefull function. Feel free to use it with Your analog sequencer.
I had use it with my Roland TB-303 sequencer.
CV/Gate - is the first step to MIDI
You can find in the web how to do that.
Of course You can play with keyboard.
There is a tumbler. You can see it at the photo.
Choose CV/gate or Keyboard.
Roland GR-700 Pedals
"The most common problem with the GR-700 are broken foot pedals. Hey, you stomp on them all the time!
Below is a video clip of replacing a GR-700 pedal. All you need is a soldering iron, some solder, and a large, flat tip (standard) screwdriver. First you will remove the twelve 3x15 mm self-tapping screws that hold the side panels on the GR-700, and then remove the 3 4x6 mm screws along the front of the unit. You can now open the GR-700 up. Carefully lift the lid. I placed the unit on the side for my repairs.
You will reheat the solder that holds the wires to the switches with a soldering iron. You may need some fresh solder to help the joint to soften.
After you have the wires off, you need to remove the pedal itself. This is the hardest part. Start with one of the plastic tabs and gently push the tab in. You do not need to push the tab in all the way. While holding the pedal in position with your free hand, do the same with the opposite tab as shown in the video. By alternating between the tabs you can gently work the pedal out. After you remove the existing pedal, the replacement pedal will snap into place. When you press the new pedal in, make certain that the four plastic clips "click" into place. Then resolder the wires and you are done.
Here is a video clip of one pedal replacement: link"
The video is from the excellent Roland Guitar Synth site. Do check it out if you haven't before.

EDP Gnat Synthesizer Schematics

"I originally bought one of these out of idle curiosity - having read all about the Wasp and its use of digital inverters in the analogue section, I couldn't resist buying a Gnat (a 'Special' in fact) when the opportunity arose. It was sold as none-working, and after replacing a few chips, I got it working. On acquiring a Wasp, and then a second Gnat, it became clear there were differences between both the Gnat and the Wasp, and between the Gnats themselves. Nothing for it to but to reverse-engineer the whole thing, and have a look-see myself! The schematics are only hand-drawn, and I make absolutely no guarantees to their correctness whatsoever (more notes follow)"
