You use an expression pedal like the Roland EV-5 to sweep the "Auto Wah" effect in the Jupiter-50 to create a classic "wah-wah" pedal effect.
First, you need to connect the EV-5 to one of the foot pedal inputs on the back panel (we will use CTRL1), and assign that input (CTRL1) to a specific MIDI message in the System settings (we will set the pedal to transmit CC06 Data Entry).
- Connect the EV-5 to the CTRL 1 pedal input on the back panel of the Jupiter-50.
- Press MENU.
- Press F3 (SYSTEM).
- Press F1 (SETUP).
- Press F2 (CONTROL).
- Cursor to "Pedal 1 Assign Source" and use the value dial to set this to "SYSTEM."
- Cursor to "Pedal 1 Assign" and use the value dial to set this to "CC06(Data Entry)."
- Cursor to "Pedal 1 Polarity" and use the value dial to set this to "STANDARD."
- Press the WRITE button, then press F5 (OK) to save this setting.
- Press EXIT twice to return to the main screen.
Next you need to select the #06 Auto-Wah effect and set the pedal to control it:
- Press Menu.
- Press F1 (EDIT).
- Press F2 (LIVE SET).
- Press F3 (EFFECT).
- Press F1 (MFX1), F2 (MFX2, F3 (MFX3, or F4 (MFX4) to select the MFX you will be using - this is determined by the routing and Layer you are using for this specific effect in your Live Set.
- Turn the value dial to select "08:Auto Wah."
- Cursor down to the "Depth" setting and use the value dial to set this to "0."
- Press F5 (CTRL).
- Cursor to the first "Source" setting and use the value dial to select "CC06(Data Entry)."
- Cursor to the first "Destination" setting (directly to the right of the Source box you just set) and use the value dial to select "Manual."
- Cursor to the first "Sens" setting (directly to the right of the Destination you just set) and use the value dial to select "+63."
You can now use the EV-5 expression pedal to sweep the wah effect in the Jupiter-50.
