The Envelope Parameters
This is a standard envelope generator with Attack, Decay, Sustain and Release parameters. It is triggered by a gate
signal connected to the Env Gate input on the back panel, or by MIDI notes on a sequencer track connected to the
ECF-42. The parameters have the following functionality:
• The Gate indicator lights up when the device receives a signal to the Env. Gate input on the back panel or a
MIDI note from a sequencer track.
CV/Gate Inputs
On the back panel of the ECF-42, you can find the following CV/Gate inputs:
•Freq CV.
Use this for controlling the filter frequency from another device. For smooth filter modulation, try connecting an
LFO to this input.
• Decay CV.
For controlling the envelope decay parameter from another device.
•Res CV.
Allows you to control the filter resonance from another device. Can be very effective in combination with filter fre-
quency sweeps.
• Env. Gate.
This is where you connect a gate signal (e.g. from a Matrix or Redrum device) for triggering the envelope.

Description
A (Attack) When the envelope is triggered, this is the time it takes before the envelope signal reaches its max
value.
D (Decay) After reaching its max value, this is the time it takes for the envelope signal to reach the sustain level.
S (Sustain) If the gate remains open (or the MIDI note is held), the envelope signal will remain on this level.
R (Release) When the gate is closed (gate CV goes back to 0) or the MIDI note ends, this is the time it takes for the
envelope signal to drop from its current value to the start value (set by the Freq parameter).
