Setup Guide
Follow these steps to set up your WIDI Jack for wireless MIDI connectivity.
1. Powering the WIDI Jack
The WIDI Jack can be powered in two ways:
- Via MIDI Out: Connect the WIDI Jack to the MIDI OUT port of your MIDI device using an appropriate TRS/DIN MIDI cable (sold separately). The WIDI Jack draws power directly from the MIDI OUT port.
- External USB-C Power: If your MIDI device does not provide power via its MIDI OUT port, or if you prefer external power, connect a USB-C cable to the WIDI Jack's USB-C port and plug it into a USB power bank or power adapter.

2. Connecting to MIDI Devices
The WIDI Jack features 2.5mm TRS jacks for MIDI IN/OUT. Ensure you use the correct TRS/DIN MIDI cables for your specific device. Optional cables for various TRS/DIN MIDI types are sold separately.
3. Initial Pairing and WIDI App
For optimal performance and to access advanced features, it is highly recommended to download and install the WIDI App on your iOS or Android device. The app facilitates firmware updates and provides step-by-step pairing instructions.
Important: General Bluetooth pairing from your device's system settings will not work for Bluetooth MIDI. Always use the WIDI App or follow specific pairing instructions provided by CME for proper connection.

Operating Instructions
Automatic Pairing
Once powered, WIDI devices are designed to automatically pair with each other and with compatible Bluetooth MIDI controllers. This "Plug, Pair & Play" functionality simplifies your setup.
MIDI Message Transmission
The WIDI Jack supports the transmission of all standard MIDI messages, including System Exclusive (SysEx) and MIDI Polyphonic Expression (MPE) data, ensuring full compatibility with your MIDI workflow.
Performance Optimization
The WIDI Jack utilizes Smart Connectivity Algorithms (SCA) to optimize performance. This includes:
- Ultra-low Latency: Achieves a latency of only 3ms between two WIDI devices.
- Adaptive Frequency Hopping: Minimizes interference for a stable connection.
- Extended Range: Provides a reliable connection up to 65 feet (20 meters) in plain sight.

WIDI App Functionality
The WIDI App allows you to:
- Perform lifetime firmware updates for your WIDI Jack.
- Optimize performance settings for latency or jitter.
- Create groups of up to five (5) standard Bluetooth MIDI controllers and WIDI devices for complex setups.

Troubleshooting
If you encounter issues with your WIDI Jack, consider the following common solutions:
- Connection Issues:
- Ensure the WIDI Jack is properly powered, either via MIDI Out or external USB-C.
- Remember that general Bluetooth pairing from your device's system settings will not work for Bluetooth MIDI. Always use the WIDI App for pairing or follow the exact pairing instructions provided by CME.
- If connection is intermittent, try moving the devices closer to each other to reduce interference.
- Performance Problems (Latency/Jitter):
- Update the WIDI Jack firmware via the WIDI App to ensure you have the latest optimizations.
- Use the WIDI App to adjust performance settings for latency or jitter if available.
- Minimize other wireless activity in the vicinity that might cause interference.
- WIDI App Not Recognizing Device:
- Ensure your mobile device's Bluetooth is enabled.
- Restart the WIDI Jack and your mobile device.
- Check if the WIDI App has necessary Bluetooth permissions on your device.
