CME WIDI Thru6 BT

This worked very well out of the box with next to no setup and had been reliable since. I'm using it to connect an Oxi One sequencer via BLE to various other synths and drum machines via USB or wired MIDI. I did struggle to connect multiple devices wirelessly (I wonder if it might be necessary to use some of the additional CME WIDI adapters if you're planning to do this) but for a single wireless device and multiple wired I'm very happy with it.

And it does it well. Connects with iPad without drama.

I use this with an iPad running Setlist Maker to send MIDI program changes messages simultaneously to two boards.
The unit pairs via Bluetooth seamlessly and I am good to go: iPad sends MIDI to the unit which sends to the boards instantly.
Great addition to the setup.
