Complex Envelope Recorder/Creator
Or simply CER (Complex Envelope Recorder) is an Eurorack module to create very complex waveforms and use them as envelope or LFO. We have 5 (now 4) ways to do it: signal input to connect any signal, audio, instrument OR sliding a pot to "draw" the waveform moving it up and down OR by moving your hand over the little LDR creating shadows over it OR internal wavetable OR shaking the accelerometer in the air (unhappily this feature was removed). You can externally/tap trigger to start and stop recording / playback and change the waveforms manually with pots to change start/end positions , shrink/stretch envelope and smoothness.
