Gakken synth bending + theremin control

Matt the Modulator shares some key solder points on the SX-150 analog synth PCB, allowing for –

  • envelope triggering
  • frequency to voltage output
  • self oscillating filter
  • LFO to filter cuttoff

To see the specific points in question, check out the photo’s notes on Flickr. He also points out that the SX-150 can be easily controlled via the output of a Gakken Mini-Theremin kit –

The gakken theremin can be used to control the SX-150 which has a much better tone and a LFO for that Violin / cello effect. The ext input of the SX-150 is a Frequency to voltage converter and so any synth can be used to control the pitch of the SX-150 but a signal with a high amplitude is needed (about 3v+)

I too have used these in combination and can attest to their awesomeness =]

    The SX-150 will be back in stock any day. (I expect them to be in this week) I will make a post when they are since so many people have been asking.
