Pitch Control with LTC1799 for Yamaha VSS-30

One of our readers sent in a diagram for circuit bending a VSS-30.

“I just finished modding my Yamaha VSS-30 with a LTC1799 Precision Oscillator from www.getlofi.com/precision. Since I couldn’t find a picture of the correct pins to wire it to online, I had to figure it out myself. I’m posting this here so that anyone looking for it in the future can find it.

Soldering to the pin that I have the white wire going to will make the LTC1799 affect both the preset sounds, and the sampled ones. I didn’t need to remove the oscillator from the board, so this mod is pretty easy to do.”
