Chorus-1 is available now!

Four BBD-based audio paths create lush sounding chorus, vibrato and flange effects. Each BBD path has its own dedicated output, allowing for quadraphonic, surround-style chorusing. Stereo summing outputs are also included.

Four multimode diode filters run in parallel, providing filtering for the four BBD audio paths. There's a bandpass mode, and a multimode, which is sweepable from lowpass, through notch, to highpass.

The real thing. The entire audio path is true analog from the inputs to the outputs. Even the modulators are all-analog.

Five conventional LFO waveforms are available as additional BBD clock modulation. Rate ranges from 0.1Hz to 40Hz. 

The Quadrature LFO produces four sine waves, each 90 degrees out of phase with the next. It can be used to modulate the four BBD clocks, producing swirling four-channel chorusing.

This modulator can produce signals similar to a Sample & Hold, but with the addition of an adjustable slew limiter and a "chaos" clock-time randomizer. Add anything from subtle nuances to extreme glitches to your sound.

A high quality, dual-axis joystick can be assigned to a number of destinations, allowing for even more expressive control.

Soft-touch, illuminated fader caps round out the experience.

Eurorack-compatible 1/8" (3.5mm) TS audio and CV inputs and outputs are included. 

Heavy duty 1/4" (6.35mm) TRS audio inputs and outputs are also included, supporting balanced and unbalanced audio.

We've spent hundreds of hours auditioning the subtle differences in tones produced from various component chemistries at specific locations in the circuit topologies, to arrive at a the sound we call Retrogradus.
