It may be an issue that has already been reported.
Right after updating the driver, I can see two devices in midi.exe.

1. First time connecting to Raspberry Pi Pico with notesend.uf installed

sendnote.uf2.zip

2. Open Device manager
3. Update KNOTE16 driver to USBMidi2.AXC
4. midi2 endpoint monitor

KNOTE16 is displayed twice.

🎹 KNOTE16
🎹 KNOTE16
🔁 Diagnostics Loopback A
🔁 Diagnostics Loopback B
🔙 (Cancel)

After Windows restert, KNOTE16 is displayed once.

Were you able to get endpoint properties on both of them? I would assume would have an Id that has "KS" and the other "KSA"

If Windows didn't tell us the KSA device was removed, there's not anything we can do, so trying to sort out if that's the case. I'll also look in the KSA code and verify there isn't a bug in there.

I've seen this too after using 'have disk' to use the new USB driver for a MIDI 1.0 keyboard.

Just a reminder that you likely do not need to reboot. Instead, just restart the service.

From talking with Gary, this problem will go away when we're officially in-box, because of the interaction with Audio Endpoint Builder.

I also had a bug in the aggregate abstraction: it was not removing endpoints properly. This will be fixed in DP7

[Psychlist1972]

Reopening after auto-close. Will close once verified in-box

Thanks, We talked about this on Discord. Will check on DP7 .Yep ,this happens after installing the MIDI 2.0 driver and not plug in/out the device or restarting the service.
