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.

This is a great solution for custom projects where you need Wireless MIDI embedded.

I had done this in my ATG guitar (below) by carefully butchering a WIDI master, but this solution is more neat and meant for this use case.

Curious about the make / model tremolo spring on rear of tremolo block?

I looks like a threaded rod, not a spring. You can see the corresponding thread in the brass block & a locking Allen bolt. Looks like it is to limit the travel of the block.


Or, is the spring the bright metal sheet at the rear?

Yes, this is a CSL Sophia StopBlock with a Semi Stabilizer plate in reverse position.

Right now it is locked with the threaded rod but the plan is to set it up as Dive Only. However this guitar has a non standard tremolo pocket and would need to route out some of the wood and install an custom built elongated Spring plate to hold the full tension of the strings.
I use very little the vibrato so it does not annoy me that much sacrificing it in favor of the ATG system.

Question: if two or more midi instruments each have their own Widi connected in a rack, for example, can they all be paired independently without interference, from one another, as long as each operates on a different midi channel? As an example, I can pair my Kemper Stage midi out to midi in on my SY1000, on channel 1, but can I then use another controller with my GR30 via another CME WIDI unit on channel 2 ?

Maybe the answers might be here

Sounds like this is a grey area, but more than two WIDI/BLE devices can be paired to one master and up to 4 slaves, or they can be paired in independent pairs.
If they are working in pairs, they are seen as a "Midi Device" so each can run on, say, midi channel 1, and the pairs will not interfere with the data of another pair on midi channel 1.
But if they are all inter-connected in a mesh network, then you will need to allocate midi channels per midi device.

That is my understanding, although the site support seems to indicate the pairing of multiple devices could be a bit flaky/ hit & miss when they "auto pair" at power on.
