Tasty Chips Electronics ECR-1 Eurorack Convolver

We originally designed this module to offer the Eurorack community access to long and lush natural stereo reverbs, and to allow tweaks in real-time with minimal delay. But it goes well beyond a mere reverb module.

The ECR-1 offers various modulation options: for instance, the position in the response sample, allowing for filter-like sweeps. Another example is modulating between two reverb spaces. It’s even possible to pitch bend the response sample in real-time. Want to record your own response and use that right away? No problem. That’s what a modular system is for, right?

Features:

– Long true-stereo natural reverbs (23 seconds max).

– Dual simultaneous reverbs (foreground and background).

– Multi-channel display with envelope and parameter-value overlays, and a clipping indicator.

– Predictive gain control (to preemptively stop the output from blowing up).

– Stereo or dual-mono input, accepts line level or Doepfer Eurorack level. Adjustable using gain control knob.

– Separate dry and wet knobs.

– Attack-Release Envelope with direct controls (2 knobs).

– Cross fade knob (cross fades between the foreground and background response)

– Pre-delay up to 2 seconds.

– Rotary encoder to quickly select responses (internal presets and the ones present on USB/SD).

– High-pass (12 dB/oct) filter with adjustable cutoff.

– Real-time pitch adjustment of response (-2 .. +2 octave).

– Dual mono (stereo pair) output.

– Record responses to USB / SD.

– Use responses from USB / SD.
