Introduction
The Crumar MojoPedals is a robust 13-note MIDI pedalboard designed for musicians seeking to expand their performance capabilities. This second-generation unit offers velocity-sensitive pedals, three integrated footswitches for control, and versatile connectivity options. It is compatible with a wide range of MIDI-enabled devices and can specifically control the rotary speaker simulator on Crumar Mojo Dual or Mojo 61 instruments.

This image displays the Crumar MojoPedals 13-Note MIDI Pedalboard from an angled perspective. The unit features 13 velocity-sensitive pedals, with a mix of black and brown keys. The top panel includes a three-digit LED display, 'DOWN', 'UP', and 'FUNCTION' buttons, and input/output ports labeled 'EXPRESSION PEDAL', 'MIDI OUT', and 'USB-MIDI -POWER-'. The 'MOJOPEDALS' logo is prominently displayed on the right side of the control panel.
Setup
- Unpacking: Carefully remove the MojoPedals from its packaging. Inspect the unit for any signs of damage. Retain the packaging for future transport or storage.
- Power Connection: Connect a standard USB-B cable to the 'USB-MIDI -POWER-' port on the MojoPedals. Connect the other end to a compatible USB power supply (e.g., a cell phone charger) or a computer. The unit will power on automatically.
- MIDI Output Connection: Connect a standard 5-pin MIDI cable from the 'MIDI OUT' port on the MojoPedals to the MIDI input of your synthesizer, sound module, or computer interface.
- Expression Pedal (Optional): If using an external expression pedal, connect it to the 'EXPRESSION PEDAL' TRS port. Ensure the expression pedal is compatible with MIDI CC output.
- Initial MIDI Channel Setup: For optimal compatibility with many devices, ensure your receiving MIDI device is set to MIDI Channel 1. The MojoPedals typically transmits on Channel 1 by default. Refer to your receiving device's manual for MIDI channel configuration.
Operating Instructions
The MojoPedals offers intuitive control over your MIDI setup. Familiarize yourself with the main components:
- 13 Velocity-Sensitive Pedals: These pedals transmit MIDI note-on/note-off messages with velocity information. Play them as you would organ bass pedals.
- LED Display: The three-digit LED display indicates the current octave transposition or other function parameters.
- 'DOWN' Footswitch: Decreases the current octave or navigates menu options downwards.
- 'UP' Footswitch: Increases the current octave or navigates menu options upwards.
- 'FUNCTION' Footswitch: Activates special functions such as cycling through patches, transposing keys, or entering configuration modes. Consult the full Crumar MojoPedals manual for detailed function assignments.
Key Operations:
- Octave Transposition: Use the 'DOWN' and 'UP' footswitches to shift the pedalboard's octave range. The LED display will show the current octave setting. You can hold a note and then use the footswitches; the octave change will apply to subsequent notes played.
- Patch Cycling: The 'FUNCTION' footswitch can be configured to cycle through patches on your connected MIDI device without requiring manual intervention from your hands.
- Key Transposition: The 'FUNCTION' footswitch may also be used to transpose the played notes up or down in semitone increments.
- Expression Pedal Control: An attached expression pedal will typically send MIDI Continuous Controller (CC) messages, often assigned to volume (CC#7) or other parameters, depending on the receiving device's configuration. The TRS expression pedal port allows for selectable MIDI CC numbers.
- Rotary Speaker Control: When connected to a Crumar Mojo Dual or Mojo 61, the MojoPedals can directly control the instrument's internal rotary speaker simulator, eliminating the need for a separate footswitch.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the MojoPedals. For stubborn dirt, a slightly damp cloth with mild soap can be used, followed by a dry cloth. Avoid abrasive cleaners or solvents.
- Storage: Store the unit in a dry environment, away from extreme temperatures and direct sunlight. If storing for extended periods, consider using the original packaging or a protective case.
- General Care: Avoid spilling liquids on the unit. Do not place heavy objects on the pedals or control panel. Ensure cables are connected and disconnected carefully to prevent damage to ports.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No power / LED display off | USB power cable not connected or faulty; power supply issue. | Ensure USB cable is securely connected. Try a different USB power supply or port. |
| No MIDI signal / No sound from connected device | MIDI cable not connected or faulty; incorrect MIDI channel; receiving device not configured correctly. | Verify MIDI cable connection. Ensure both MojoPedals and receiving device are on the same MIDI channel (typically Channel 1). Check the receiving device's settings. |
| Footswitches ('DOWN', 'UP', 'FUNCTION') not responding | Unit malfunction; software glitch. | Power cycle the MojoPedals (unplug and replug USB power). If the issue persists, contact Crumar support. |
| Expression pedal not working | Expression pedal not connected correctly; incompatible pedal; receiving device not configured for expression CC. | Ensure expression pedal is fully inserted into the TRS port. Verify the expression pedal is compatible. Check your receiving device's MIDI CC assignments. |
