Slip into a moving halo of analog motion where chorus, vibrato, flanging, and filtering all live in the same richly animated space.
Chorus-1 by Retrogradus is a true analog, desktop modulation instrument built around four BBD-based audio paths, giving you everything from classic lush chorus and liquid vibrato to metallic flanging and experimental textures. Each BBD path has its own dedicated output for quadraphonic or surround-style setups, with stereo summing outputs ready for more conventional rigs. Parallel to that, four multimode diode filters provide tone-shaping per path, offering a dedicated bandpass mode plus a sweepable multimode that glides from lowpass, through notch, to highpass.
Modulation is equally deep. A five-waveform LFO covers rates from slow 0.1 Hz sweeps to fast 40 Hz modulation, while a Quadrature LFO generates four sine waves 90 degrees out of phase for swirling, four-channel movement. The Texture Generator adds controlled chaos, producing sample-and-hold-style variations with adjustable slew and a clock-time randomizer that can sprinkle gentle animation or full-on glitch across your sound. A high quality dual-axis joystick can be assigned to multiple destinations for expressive, hands-on performance, complemented by soft-touch illuminated fader caps that make real-time tweaking feel like playing an instrument in its own right. Chorus-1 is designed to sit comfortably between studio and modular worlds, with Eurorack-compatible 3.5 mm TS audio and CV I/O alongside heavy-duty 1/4" TRS audio connections that support balanced or unbalanced operation. Every stage of the audio and modulation path is fully analog, the result of extensive component auditioning to achieve the distinct, characterful sound Retrogradus calls its own.
