MIDI: support virtual wires/plug #31
Conversation
Allow to specify the number of virtual wires/plugs to be created for the MIDI interface. Initializing the MIDI device with: Adafruit_USBD_MIDI usb_midi(3); xports a single device with three separate ports/jacks/wires. The ID (4 bit) of the jack/port is carried in the header packet of the USB MIDI wire message.

Thank you for the PR and your patient, I fixed the travis build by syncing the nrf52 usb repo with the core PR. Can you include the multiple jack example that you mention #27 (comment) here to the PR as well. That will make it easier for user to get started. |
The current byte-stream API in the library just drops the USB protocol bytes which are needed to make use of the virtual wires/ports. The API needs to be changed to not mangle the USB packets. The example will not work correctly otherwise. I think we should only include it with the next change, when we convert the API to a packet interface? I have not submitted it yet, it needs some cleanup. I just split out this PR, to make it smaller. I'll clean this up next and submit it: |
Got it, I am looking forward to your next PR |
