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)
The Triple Vactrol Resonators 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-Vactrol-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.
Triple Vactrol Resonators – BOM and Schematics
Features:
Three Band Pass Filters each with:
- 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)
- rate potentiometer
- LFO output
The LFO is normalled to the 3 CV inputs, however, for the 3rd CV input the LFO signal can be inverted.
Specs:
- 12HP
- Depth 40mm
