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?
For the manual, and other resources, please see the ECR-1 downloads page.
– Long true-stereo natural reverbs (20 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.
