Windows Support for MIDI over Bluetooth LE

[lakere]

Just read this KVR article concering Windows support for MIDI over Bluetooth LE.   I"d love to see this feature in vArranger.

Bluetooth MIDI Controller Support
As the first Windows DAW to support wireless Bluetooth MIDI controllers natively, Cakewalk CTO Noel Borthwick explains "To deliver seamless connectivity to the next generation of MIDI devices, we've adopted Microsoft's new API standard for using MIDI on Windows as part of the Universal Windows Platform (UWP) architecture—which provides a modern, extensible way to communicate with MIDI."

Could someone help me with bluetooth MIDI ?
I can get it running but only for 1 Minute.
Afterwards ist disconnects the Bluetooth device.
I´m using a Rolan GoKeys.
On the IPAD everything is fine.
But with the windows tablet and Varranger2 I Can not get it running.
The Tablet has Windows 11 installed.
Is this the problem ?
It would be very nice, if someone could help me with this.
I am starting VArranger in Administrator Mode.

What is your Bluetooth midi model?
I tested the Korg micro key air few years ago and it was not reliable. Going off every few minutes

I am trying to use a build in one in my new DELL Tablet PC.
I had the same issues with an M-Audio Audio Interface in the Pro Keys Sonos 88 Keyboard.

I tried using different compatibility Modes (Windows 8/Windows 7, usw.). But nothing solved the problem.
Or is the latency to high for using either the internal Synthesizer, the USB Audio streaming or Bluetooth.
The only way to have reliabel results seems to be using the Keyboard via USB MIDI in GM2 Mode.
I also can not put an instrument to the selected instruments by using the touch function. Trying 10 times results in one time with success.
I think I will have to connect a Bluetooth Keyboard with touch Pad either.
But I bought the tablet only for VArranger Use.

OK I understand it more now
The Roland GoKeys has Bluetooth midi included

Windows doesn't expose the Bluetooth midi devices to standard windows apps like vArranger
So maybe you can install this app

https://www.tobias-erichsen.de/software/loopmidi.html

and

With loopmidi, you can first create a new virtual port

And with midiberry, you can send to the virtual port, all what is received by bluetooth

Then in vArranger, you can receive the bluetooth midi in the virtual port

I can see in this video that someone did it :

Note that USB midi will always be more stable and lower latency than bluetooth, but if wireless is needed, then maybe it can work correctly. Let me know

If yes, maybe I can try to implement later a wrapper to receive bluetooth midi directly in vArranger (working from Windows 10)
