Unique identifiers for duplicate MIDI devices

[cpenny]

device.

From looking at juce_mac_CoreMidi.cpp and the CoreMIDI library I’ve found that the CoreMIDI MIDIGetSource() function will return a unique number, and so far using this appears to fix my problem.

Is there any reason why using MIDIGetSource() to get a unique identifier is a bad idea?

Are there any alternative options? I tried using the kMIDIPropertyUniqueID parameter but this always appears to return any empty string.

I haven’t yet tested this on Windows yet, but assuming I’ll run into the same problems is there an alternative to MIDIGetSource() in the Windows MIDI library?

Thanks.

Having the same issue myself! It is also important that the same device connected via Bluetooth or USB can be distinguished.

Edit: The above fix on the develop branch works perfectly for me! I need to be able to support multiple instances of the same “Device” via USB or BLE (since the device can be run wired or wirelessly). Switched to using getAvailableDevices() and everything works like expected.
