Describe the bug A legacy MIDI app which uses MME MIDI API cannot receive System Exclusive messages through a MidiSrv enumerated port.

To Reproduce

  1. Load the attached firmware to the ProtoZOA.
  2. Make sure the USB MIDI 2.0 driver (UsbMidi2.sys) is loaded.
  3. Open midi.exe and monitor the ProtoZOA.
  4. Open the Pocket MIDI 64bit(MME MIDI app) and choose MidiSrv enumerated ports for Input and Output. Input: AmeNote ProtoZOA I-1 Output: AmeNote ProtoZOA O-1
  5. Open the MIDI In Monitor and the MIDI Out Monitor windows.
  6. From the "Views" menu, open "System Exclusive" window.
  7. In the System Exclusive window, type "F0 01 F7" as a message to be sent. Image
  8. Click "Transmit" to send messages.

In the MIDI Out Monitor of the Pocket MIDI shows the sent message as below: Image

The midi.exe monitor shows the received message as below: Image
