Moon Jock

EM-201 | Envelope Generator

The Moon Jock Envelope Generator is a highly versatile four-stage ADSR module. The envelope generator has an extremely ‘snappy’ attack response time of 0.4ms, and a maximum response time of 12s. Its decay and release response times carry a minimum response time of 2.5ms and a maximum response time of 22s. Moon Jock also provides individual CV inputs for Attack, Decay, Sustain and Release. The Level knob functions as an attenuverter, which combines attenuation and polarity inversion in one control.
 The generator varies from 0V to +10V.

The module offers expansive voltage control for Trigger, Gate, Decay, and Release parameters. 
The positive-going edge of any waveform presented to the TRIG-RETRIG IN input is treated as a trigger pulse. When the voltage of any waveform presented to Gate In input reaches +1V, it is treated as a gate that is held open until the voltage drops below +1V.



The Auto-Repeat feature captures and cycles the output as determined by the Attack and Decay stages. In doing so, the module can also function as a low-frequency oscillator. The frequency of the LFO is determined by the time lapse of a single Attack-Decay cycle. Therefore, the Attack and Decay controls can be used to control the repeat rate.



The minimum repeat rate is approximately 0.02 Hz, and the maximum repeat rate is approximately 350 Hz.



In Gated Repeat mode, the envelope only repeats when gate signal is presented to Gate In.

 The Hold switch holds the envelope voltage at the Sustain control level. The Manual push button provides a momentary Sustain hold.
