Press FX while playing to enter the effects menu. Use minus and plus to browse the available effects, then move the fader to set the send level for the current group.

Available effects

  • Delay, reverb, distortion, chorus, filter, and compressor

Changing which group receives effects

Each group can be sent to one master effect independently. To adjust a different group's FX level, press that group's button (Group A through Group D) to select it, then move the fader to dial in the send amount.

Adjusting effect parameters

Once you have chosen an effect with minus and plus, use the knobs to shape it. knobX typically controls the main parameter (such as delay length or reverb size) and knobY controls a secondary parameter (such as feedback or color).

Live input

You can also process audio coming through the line input. In main mode, turn knobX to adjust input gain and knobY to set the FX send level for the live signal.

Pro tip

Hold FX and press a group pad to solo that group while playing. Hold FX and press multiple group pads to solo more than one group at once.
