MIDI output voltage: WIDI Master is getting hot

[Keybi]

I think this is a known issue with the midi power on the FM3. There was a another post where someone installed a current limiting resistor on the pin to fix this issue

Well, I wouldn't say it's a problem on the FM3 side. As I mentioned above, this midi adapter works without any problems. https://www.quicco.de/en/
I think there is a problem with the midi adapters from Yamaha and WMI.

No, a spec'd current limiting resistor for the MIDI circuit is missing on the FM3, though it seems some external devices have better voltage regulation than others. Adding the resistor to the circuit or cable can cure the problem.

Interesting. The topic is not so relevant for me except for the fact that it would work if I needed it, which I don't. I've had the mi1.II lying around for a long time and just tested it.
It doesn't heat up.
So I might consider this product.

Yeah, if it works without problems, no need to fix.

I’m using a Roland WM-1 with a AAA battery on the FM3 to receive MIDI over Bluetooth from BandHelper on an iPad for patch changes. It has been going all day without overheating.

Just a quick tip, when you're pasting/sharing an Amazon link, you can rid of "ref= ..." and everything after that. Makes for a more manageable link for pasting.

I tried that same one and it became hot immediately upon powering up the FM3. I wonder if this is an updated version
