The Black Dual ASR EG is a versatile, full analogue looping AD/ASR envelope generator with voltege control over attack and release times, that can also be used as low frequency oscillator with manually and voltage controlled shape and rate. It has two identical parts, each featuring all typical envelope generator controls and bonus features – the end of the cycle output and bi-polar LFO output. When in loop mode the shortest attack and decay settings turn the module into voltage controlled drone oscillator with adjustable waveform (it will not track 1V/oct, though).
