Here is a really nice guitar synth setup using the Analogue Systems rs35 module along with 5 other A.S. modules. The rs35 does a remarkable job of turning the guitar pitch into CV (control-voltage).

The rs35 module is a frequency (or pitch) to voltage converter. It can turn virtually any sound source into a one volt per octave voltage allowing you to control an analog synthesizer.

We are running a Strat into the Barber Electronics TonePress compressor pedal for added sustain. The guitar signal is then run into the low pass filter section of the A.S. rs110 Multimode filter to roll off some of the highs.

Now we run the audio into the rs35 'Frequency In'. The rs35's voltage out goes to the rs95 voltage controlled oscillator. We're using various modules to alter the oscillator sound including the rs100 Low Pass filter, the rs120 Comb Filter, and the rs290 voltage controlled digital delay/sampler.

Finally, a practical, easy way to play your analog synthesizer with a guitar. Rad.
