dual-channel effects processor and feedback synthesizer

Four feedback paths sit at the core of the Laboratory. Route signals, control delay repeats, or add gritty textures. Push them far enough, and the system enters self-oscillation—even with no input. From there, every control reshapes the feedback into anything from subtle drones to harsh noise madness.

Each channel features three voltage-controlled effects: gain, delay, and filter. Run the channels in series or in parallel. Push signals from silence to amplification with the Gain control. Drive the Delay into dirty territory at longer times—we’ve used that famous karaoke machine delay chip. Combine both channels to create multi-tap or ping-pong echoes.

The Resonant Filter provides Low-Pass and High-Pass modes. Chain the two channels in series to create Band-Pass responses. A final clipping stage at the end of each channel adds compression and distortion when driven to extremes.

We’ve also included a global Modulator that can operate as either an Envelope or an LFO, with two positive and two negative CV outputs. Patch them to build effects like tremolo, vibrato, chorus, moving stereo filter sweeps, modulated delays—it can get pretty wild.
