Gakken SX-150 Ribbon Synthesizer, Modified

via this auction

"I have this one modified with a CV or control voltage input, which I used with an Arduino in order to play it using a MIDI keyboard. That might sound fairly crazy, but if you look online, there are instructions for much more than that. I also modified it to have a mono 1/4" jack output, which is the same as what a guitar output is. This makes the thing more useful as an actual instrument.

I also hacked on a jack for a 7.2v radio controlled car battery, as I have a bunch of them sitting around, they're fast to charge, and something like this runs forever off of a battery like that. The bottom of the synth is open, so if you don't want the battery jack, you can just snip it off.

Also included is the magazine that the synth original came with. Lots of interesting photos, but almost all in Japanese."

Double Andore test (#4)

"... sans manual, the learning curve of The Harvestman's Double Andore module (essentially two AD / AHD envelope generators & two VCA's with HEAPS of cross-modulation & routing possibilities & several pre-programmed wave-shapes on a set of digital voice-boards) is significantly steeper than most (save for the MakeNoise Maths, with which it shares some functional similarity / complexity, even if they sound/work in COMPLETELY different ways) ; watch as i fumble through discovery, arbitrarily twisting knobs until it starts sounding like "music" (i kid, i watched the Trash Audio video about 15x just now & even made a little "map" in my notebook) ...

This video was shot with a Canon Digital Rebel T2i (with the macro lens) hovering about 6 feet above the synth ; audio was piped directly out of a Radial Stereo Direct Inject box into the stereo "mic" input of the camera (hence the overall dynamic awesomeness) ..."

I was trying to figure out what the repeating sound that comes in at about 9 seconds reminded me of.
Here you go:
