#Fedihelp on #MIDI on #OSX #Moneterey out there?
I have this noname #USBmidi cable. It works class compliant out of the box on #Linux / #UbuntuStudio 24.04. A tiny LED on the USB plug shows incoming MIDI, which I can also see in #GMIDImonitor after routing it in #Patchance. (#Pipewire audio system.)
On #MacOS I am lost. The tiny LED does not light up on incoming MIDI. Apparently this USB device is not even activated by the OS.
It also cannot by detected in “audio midi setup”.
I mean, this is OSX, the supposedly easy OS for creative people… what's going on?
EDIT: It turns out that this might be not an OSX problem. The USB MIDI does not show up as soon as the MIDI is plugged in. I guess this is a leakage current problem which might in the end even destroy USB ports. Power supplies without ground connections are prone to this error (those by Apple, too). A MIDI interface should be opto-coupled, but many actually aren't.
