Setup on the Mastermind GT requires only a few steps:
1. In Mastermind GT setup, select Edit Devices.
2. Select a device slot. If you’re starting with a Mastermind GT that’s in the factory state, select the “Effect
Gizmo” slot and you can overwrite it. If you also have an Effect Gizmo, you can leave the “Effect Gizmo” entry and instead select one of the empty slots.
3. Press the Type button, then select Fractal Audio. Next, select Axe-Fx III.
4. Press the Set Default Buttons button and press 1. This sets up button page 1 with a default set of
buttons that control the Axe-Fx III.
5. Press the Set Default Pedals button. This sets up the GT’s expression pedals to control the Axe-Fx.
There’s a little more expression pedal setup required on the Axe-Fx, which is described in the next
subsection.
6. Optional: Use the Get Preset Names feature to read the preset names from the Axe-Fx. This process
is described in the Reading Preset Names with Scenes section.
7. Exit setup mode.
Expression Pedal Setup
Following the previous steps sets up the GT’s expression pedals to send the correct CC numbers. Some more setup on the Axe-Fx is required.
In the Axe-Fx’s setup menu, go to MIDI/Remote and select the External page. Set External Control 1 to CC11, External Control 2 to CC12, External Control 3 to CC13 and External Control 4 to CC14.
To assign an expression pedal to an effect parameter, edit the effect in the Axe-Fx. Select the parameter you want the expression pedal to control and press the Modifier knob on the Axe-Fx. Set Source to “External Control 1” to assign it to the first expression pedal, “External Control 2” to assign it to the second expression pedal, etc. For a more detailed description, please refer to the “MODIFIER TUTORIAL: WAH PEDAL” section in the Axe-Fx III manual
