MOTM 1800 frac looping ADSR module


via this auction

"MOTM 1800 looping ADSR envelope. this module had banana jacks installed to replace the 1/8 jacks. the work was done by Michael Ford of Metalbox

the module generates a traditional adsr envelope at the 2 output jacks. when gate goes high (exceeds +2.5v), the attack/decay portion completes to the sustain level. the envelope stays at the sustain level until the gate signal goes low, then it releases to 0v. the trigger signal is optional: if your midi-cv controller can output a trigger pulse (1ms-10ms nominal width), the envelope will re-attack/decay when a trigger pulse is present. pressing the red manual gate pushbutton will also start the adsr cycle. the motm-1800 has 2 other modes: looping and burst. in the loop mode, the module acts like a lfo: the ads cycle repeats forever. note that the release control has no effect in the looping mode. for maximum output voltage swing in this mode, set sustain to the '0' tick. the fastest the loop will run is when attack and decay are both 0 and sustain is at 0 (looping will stop if sustain is set over the '6' tick). this will be about 620hz. if looping does not begin when you flip the switch, press and release the manual gate. in burst mode, the envelope will loop as long as gate is high. when gate goes low, the looping stops and the envelope does a release at the rate set by the release control. you can also burst with the manual gate pushbutton."
