assigning a parameter to the Expression Pedal is as follows:

2. Press the
SELECT
button until the light in the Expression row of the Matrix’s LED begins flashing.
3. Rotate the Number 1 Knob to select the Expression pedal 1,2, or 3.
Note: You can assign three parameters to the Expression pedal per preset.
4. Rotate the Number 2 Knob to select the parameter the pedal will control.
5. Rotate the Number 3 Knob to adjust the minimum value the pedal (toe up) reaches.
6. Rotate the Number 4 Knob to adjust the maximum value the pedal (toe down) reaches.
7. Press the
STORE
button to store the changes. See page 8 for more information on storing presets.
