Electra One App - "Your Electra One is not connected."

EDIT: This works with Firefox, so it moves the problem from Computer/OS/Mk2 to the browser.

I’ve been unable to connect to the App/Editor, even after following the advice across various threads here and Controller Not Detected | Electra One Documentation .

I’m starting to suspect that a recent MacOS update might be behind this, As everything ‘just works’ when trying on a different computer, but I could use some support. Will give all the gory repro steps/details:

System Stats:

  • Mac Studio M1 Max
  • MacOS Tahoe 26.6.2
  • Electra One mk2 v4.1.4 (verified in Settings > System on the device)

I started by:

  • Shutting down all applications that might be accessing my Mk2
  • Logging out of the Electra One App
  • Unplugging the device
  • Removing the existing entry in chrome://usb-internals
  • Removing the device from MIDI Studio
  • Restarting my Mac

Then:
Using the supplied cable, plugged it back in, ensuring it’s going directly into the back of my Mac.

Verified it appears in System Information:

Confirmed that it appears/is active in MIDI Studio:

Verified that the device was added after being prompted by Chrome to allow/deny:

After logging back in, I still get the message even though I can select the CTRL port:

And despite the fact that MIDI Monitor shows that it can see the CTRL port and that messages are being sent from Port 1 via the same connection:

Thanks in advance!

Which chrome version? You need to update to 153, there was a bug in 152

I was on 152, updated to 153 and that fixes things with the direct connection. Thanks!
