I have an ATMEGA 2560 platform running HIDUINO and a sketch based on the stock MIDI library. I'm intending to use it to convert Linear Timecode (LTC) to MTC. Got a long way through the project - LTC decoding working fine, timer configuration OK, and Midi output working fine. It's just that as soon as I try and generate MTC messages, they are being dropped before they land on the computer USB interface.
Equipment to hand: Macbook Pro running El Cap/Reaper and Protools., ATMEGA2560 MEGA R3 (With 16u2 for HIDUINO) and small audio interface circuit.
Using Timer 4 for LTC Decoding and Timer 5 for MTC generation (4 messages per LTC Frame).
Midi Monitor on the OSX box.
Sees Note on/Note off packets quite happily, but no MTC messages are registering.
I do note the TX LED is active during MTC Message generation, indicating that the sketch is actually generating messages and sending them to the 16u2 chip.
Specifically, my question is how do I get the MTC messages through HIDUINO into the computer?
