1 EG 1 Gate Input :
The Envelope Generator cycle of EG 1 is started (triggered) by a gate signal to this Input,
alternatively it can also be triggered using the EG 1 Manual Trigger switch (3). The
Eurorack standard gate voltage is + 5 Volts, however any voltage above +2V will trigger
the EG successfully and gate voltage levels up to +10V are acceptable.
2 EG 1 Gate Input 2 : This is the Gate Input for EG 2 and performs in the same manner as EG 1
3 EG 1 Man Trigger : Pressing this button triggers the Envelope Generator, sustain will be active for as long as
the button is held down - it is the equivalent of pressing a note on a keyboard.
4 EG 2 Man Trigger : This is the manual trigger button for EG 2.
5 EG 1 Attack :
Sets the speed of the attack cycle of EG 1, which can be varied from around 10 millisec-
onds to 10 seconds.
6 EG 2 Attack :
Sets the speed of the attack cycle of EG 2, which can be varied from around 10 millisec-
onds to 10 seconds.
Controls, inputs and outputs
7 EG 1 Decay :
Sets the speed of the decay cycle for EG 1, and can be varied from 10 milliseconds to 10
seconds. The decay cycle commences either when the attack reaches its maximum level
or the gate pulse ends, whichever happens sooner.
With the gate high (on) the envelope will decay down to the sustain level. Immediately
the gate goes low the decay recommences from the sustain level and decends down to
zero at the rate determined by the EG 1 Decay Control - see Fig 1.
