STM32F4 AND iOS - shows only 1USB-Midiport (in Miosstudio) while on Win i have 4!

[Phatline]

see title.... a friend of mine has a iOS device (apple), there it shows only 1 USB-Midiport, while on his Win-PC with the same STM32F4-Board it shows 4 Ports!

 

any idea to fix this on iOS?

MacOS caches your USB MIDI ports, to see the four new virtual USB MIDI devices after your initial firmware upload of the LoopA app, please perform these steps: * start the Audio-MIDI-Setup of MacOS (e.g. search for "audio-midi" with Spotlight) * disconnect the core module from USB * delete the interface in the Audio-MIDI-Setup * connect the core module to USB again.

Hope it helps!

thanks for the thip... he says he has a Ipad... but maybe there it is the same problem, but with a extrem more complicated way to do that solution...

I see all 4 ports by connecting a Seq4 via USB with my iPad.

It is not possible to see Midi Ports in the System, you see it just in an App like Cubasis or an App which supports Midi. Also it depends on the IOS Version, I guess. Midi is available at all IOS Versions but maybe all 4 are not shown by older ones.

...thanks for feedback.

he solved it this way:

solution was completely resetting all settings on the iPad as it only sticks to the configs of when you plug TM in for the first time, can change ports/names all you want after but it won't refresh them without a hard reset.
