Description

THIS VIDEO BELOW IS OF THE OLDER LARGER MODULE, THE NEW SLIMMER MODULE SOUNDS EXACTLY THE SAME. i.e. AMAZING. (headphones recommended for the full frequency response)

This Triple Resonator module is based on the classic circuit as found on the PS3100, but what is it actually? Basically the module incorporates three voltage controlled band pass filters with fixed bandwidth (resonators), using the Dual-VACTR0L-based core from the PS3100, and a simple resettable triangle core LFO. By setting the BPFs to different center frequencies and modulating them, we get these nice resonating sounds. Depending on the source waveform and the modulation it might even resemble the human voice. The original purpose, however, was to make string patches sounding more vivid.

  • CV input + attenuator potentiometer
  • initial frequency potentiometer
  • LED

One summed audio output, one common audio input

One LFO with:

  • reset (sync) input
  • range switch (slow, fast)
