WIDI Core (N/XN)

The source of CME's WIDI technology

WIDI Core is your smart (BLE) breakout board that implements premium MIDI over Bluetooth Low Energy functionality as designed & developed by CME.

The breakout board can be built into any existing piece of MIDI equipment that features MIDI I/O. Power consumption is ultra low and it works natively with Apple iOS, MacOS, Windows and Android. It can also play both the central and peripheral role to connect to any existing BLE MIDI peripheral, such as Roland AX Edge, Korg MicroKey Air, Roli Seaboard, CME Xkey Air, Jamstik+ Guitar, etc.

Please note for implementation in CME's WC series of MIDI interfaces, you will require WIDI Core. Not WIDI Core N or XN.

Smart Connectivity Algorithms

WIDI distinguishes itself from any other Bluetooth MIDI technology available through its unique SCA technology. SCA is a collection of highly effective algorithms that optimise the performance of WIDI in any given situation. SCA stands for Dual Role Automation, Automatic Pairing Mode, Smart Hub Functionality, Latency Reduction Optimisation and Range Performance Optimisation.

With WIDI you add the most advanced wireless MIDI technology available to your MIDI project.

FCC Statement
Any Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired operation.

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
