Conjured Circuits - Suiseki Phase Shifter (MU)

The Conjured Circuits Suiseki Phase Shifter is a collaborative effort between Conjured Circuits and Old Crow to bring their popular phaser module into the MU format. Some additions are included in this port, including an internal LFO output to use as a modulation source.

From the original Old Crow documentation:

"Suiseki in Japanese refers to a decorative formation of small stones, a name I thought fitting for a modular implementation of the vintage Small Stone phase shifter. The Suiseki is a module that uses an updated version of the original Small Stone circuit where the long-since discontinued CA3094 OTA+buffer ICs are replaced with widely-available LM13700 dual OTAs. The buffers are provided by discrete transistors as this allows the use of either OTA part number without the effects of the LM13700 bias on the buffer stages."

Coming in Jan 2020 as both an assembled module and a DIY kit available exclusively through SynthCube. Documentation and demos coming soon.

To answer some questions:
  • -The Small Stone Phaser pedal is a 4-stage design, and this module is as well.

    -The CV IN jack is switched, so plugging into CV IN will break the connection of the internal LFO to the phaser core, and instead use your CV, whether that be your own LFO, pitch voltage, etc.

    -The LFO output will be the same "hyper triangle" waveform as was used to modulate the Small Stone pedal. I call it the "tear drop" wave, as it looks like a sine wave with a bad diode. See picture below.
