I’d like to ask a question about my MkII. I had relatively recent (before 3.5.4) firmware.
I started the E1 connected to a mioXL that has always worked. E1 started and restarted over and over and over again. I disconnected, then reconnected directly to a handy MacBook Pro. It started, and stayed stable. An hour later it remained stable.
I reconnected E1 to the mioXL in question, and this time it remained stable there too!

However, because of the wierd behaviour before, I thought the-firmware-thought.
Checked and saw that app.electra.one said there’s a newer stable firmware, that I should update, so I did.

Got the same behaviour as before, ie when E1 is connected to that mioXL, E1 starts and restarts as long as I let it. Disconnecting, then connecting directly to the Mac, gets the stable behaviour.

I sort-of-need that mioXL since E1 has always seemed to work (MIDI DIN) with a number of hardware units connected to that mioXL which is convenient. Any guesses as to my next step?

You could try putting a powered USB hub in between to see if that fixes things, if so then it is a power issue

Electra restarts like that when there is not enough power. I assume it reboots after the initial start up screen is completed. That’s the moment when power hungry processes start. As a MioXL owner I know that not all Mio’s port can deliver enough power. Try different USB ports on your Mio or, as @markus.schloesser suggested, use a powered hub or Y-cable to provide more power. Also note, power requirements (within the 500mA limit) can change with individual firmware releases.

Thanks, changing USB-A port on that same mioXL did the trick!

@Martin Bug: In a list with values C C# D etc. the # is displayed as a space. See e.g. Electra One App the transpose key control.

I’m using the following function in 3.5.4. It does show the #.

notes = {"C %d ","C#%d","D %d ","D#%d","E %d ","F %d ","F#%d","G %d ","G#%d","A %d ","A#%d","B %d "}
function displayNotes (valueObject, value)
  return (string.format(notes[math.fmod(value, 12) +1], (value// 12)-1))
end

Never mind @Martin. My bad: it turns out to be the Unicode ♯ character that got dumped by the remote script.
