After reading Mickey's article on Sequencing the Gakken SX-150, I was inspired to follow suite and install a pitch resistor jack in a Gakken Synth as well. I ended up finding a good deal at the Men's Gangu eBay Store, shipped straight from Nippon (fast shipping and good service, btw). I followed the article and installed the jack with no problems, and then did this test session.
In the video: Delptronics Bender Sequencer controlling the Gakken SX-150, which is routed in series through the Mtron+Delay, while the Duo feeds it's input jack.
All Master Clock duties handled are provided courtesy of Wooster Audio's MIDI-IR 2, sending sync via midi clock to the Monotribe, and also to the Bender Sequncer via IR sync (you gotta love Austin).
