EG-2

Voltage Controlled ADSR Eurorack module built into a slim 6 HP format.

The EG-2 is a voltage controlled ADSR module. All parameters of the ADSR envelope are fully voltage controlled as well as with potentiometers. Voltage control input is summed with the potentiometer control.

Inputs

Gate - Voltage to this input starts the ADSR cycle and ends when voltage drops to 0. Typical voltage needed to start the ADSR cycle is 2.3V to 5V. Maxium voltage input is +11V.
Trigger - A voltage to this input of at least 1.1V will initiate an AD (attack, decay) envelope. Once initiated the envelope will complete and drop to an output of 0 volts. Subsequent voltage inputs will re-trigger and start the AD envelope again.
VC for attack, decay, sustain, release. Expected VC input is -5V to +5V. The input voltage is summed with the voltage coming from the parameter's potentiometer voltage.
Envelope Output

Mininum Attack Duration - ~1.8ms
Maximum Attach Duration - ~38 seconds
Maximum Release Duration - ~70 seconds
Maximum Decay Duration - ~58 seconds
Maximum Sustain Voltage - 5V
Attack Peak - 5 - 5.3 volts
Additionally the EG-2 has an output that sends a constant +5V while the attack phase of the envelop is active.

There is also a tactical switch for manually initiating the ADSR, actiing as a voltage to the Gate input.

The EG-2 comes as a fully built and tested module
