THE EFFECT DEVICES

354

The ECF-42 filter section has the following parameters:

The Envelope Parameters

This is a standard envelope generator with Attack, Decay, Sustain and Release pa-

rameters. 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 parame-

ters have the following functionality:

D 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:

D Freq CV.

Use this for controlling the filter frequency from another device. For smooth filter

modulation, try connecting an LFO to this input.

D Decay CV.

For controlling the envelope decay parameter from another device.

D Res CV.

Allows you to control the filter resonance from another device. Can be very effec-

tive in combination with filter frequency sweeps.

D Env. Gate.

This is where you connect a gate signal (e.g. from a Matrix or Redrum device) for

triggering the envelope.

Parameter

Description

Mode This button sets the desired filter mode. Three modes are available:

24dB/octave lowpass, 12dB/octave lowpass and 12dB/octave

bandpass.

Freq This is the filter cutoff frequency.

When using the ECF-42 in “static” mode (without triggering the enve-

lope), this parameter adjusts the frequency content of the sound.

When using the envelope, the Freq parameter serves as the start and

end frequency for the filter sweep.

Res This is the filter resonance. Raising this produces a more extreme,

“synthy” effect.

Env Amt Determines how much the filter frequency should be affected when

the envelope is triggered. The higher the value, the more drastic the

effect.

Note though, that if the Freq parameter is set high, raising the Enve-

lope Amount will not make any difference over a certain value! This is

because the filter is already fully opened - try lowering the Freq pa-

rameter in that case.

Velocity This parameter determines how much the gate velocity value should

affect the envelope amount.

Parameter

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 sig-

nal 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).
