Roland SPV-355 rare analog synth pitch-CV Gate

Trope SPV-355 Hog pt.2 video upload by siebenjager

Note Part 1 was not on YouTube.

"Trope generative music run through Roland SPV355 pitch-voltage analog synth, Space Echo, and Electroharmonix HOG. One channel of the iphone stereo output went to the HOG while the other fed the SPV-355 and the Space Echo in succession. The SPV is intended to track a monophonic input source so it gets glitchy as it locks onto different harmonics. More endless noodling."

"fed it a cleaner signal this time, the hog output at octave up setting fed the 355 which then used the pitch conversion."

"This is a pretty unique little synth, it has a similar feature set to the SH2 with some differences but is a good alternative that fits in a rack. There is a front panel audio input that takes a monophonic signal, like a voice or a bassline, and generates voltages for the pitch CV (1v/oct), gate and envelope (followed from the source). You can then use these to control the internal 2 Oscillator analog synth, an external synth via CV/gate/envelope, or both simultaneously. There are also CV/Gate inputs for use as a standard synth module, you can use any cv/gate keyboard or midi/CV converter that gives 1v/octave. Audio ins and outs (with the exception of the effects send/return) are on the front panel and CV/gate I/O is on the rear.

I just posted some videos of it in use on Youtube under user ID siebenjager [below]. My favorite thing about it is how crude the pitch to voltage converter is, it makes it easily abusable. It tends to be more interesting when mistracking, though you can get it to track well if you send it a very clean well defined harmonically flat mono signal (like an oscillator or organ tone). When I want to use it as a "normal" synth I just run it off the CV/Gate inputs. For someone looking for a flexible guitar synth, this is probably the last thing I'd recommend. Ironically, I think this was its original intent as the output is pretty low output, probably -20, intended for an amplifier. But for someone looking for new sounds that wants to also be able to use bread-and-butter monosynth sounds this would fit the bill."
