5. Create a Matrix Pattern Sequencer.
If you flip the rack around, you can see that the audio out from the Subtractor is passed through the ECF-42 and
then on to the Mixer. The Matrix Curve CV is connected to the ECF-42 Frequency CV parameter, and the Matrix
Gate CV is connected to the ECF-42 Env Gate input.
6. Select the Track connected to the Subtractor (given that you are handling MIDI input via the sequencer) so that
you can play it from your keyboard.
If you play a few notes and turn the ECF-42 filter freq knob, you should hear the sound being filtered.
7. Draw a Gate pattern in the Matrix, using mixed velocity values.
Draw only a Gate pattern, not a Curve pattern.
8. Set both the Env.Amt and Vel knobs on the ECF-42 to about “40”.
9. Click the Run button on the Matrix panel.
10.While in Run mode, hold a chord down on your keyboard.
Now you should hear the envelope (controlling the filter) being triggered with every gate step.
D By increasing the Env.Amount, you determine how much the envelope parameters should affect the filter fre-
quency.
D By increasing the Vel. parameter, you determine how much the gate velocity should affect the filter frequency.
D If the filter effect isn’t very noticeable, try lowering the filter frequency, and raising the Res value.
11.Set both the Env.Amt and Vel knobs on the ECF-42 to “0”.
12.With the Matrix still playing, draw a Curve pattern in the Matrix pattern window.
Now, you should hear the filter frequency being modulated by the curve pattern. By combining the various param-
eters you can create many new filter effects.
q You can also control the ECF-42 from other devices with CV and/or Gate outputs.
