Hello,
Sorry for my poor english.
I can't understand how to transmit messages via usbMIDI using virtual cables/ports.
I'm not using Serial Transmission.
I would like an example to understand the operation.

Teensy 3.6 >> DAW
(Port 1) - usbMIDI.sendPitchBend(value, channel);
(Port 2) - usbMIDI.sendPitchBend(value, channel);
(Port 3) - usbMIDI.sendPitchBend(value, channel);

I hope someone can help me

Thank you
