ok thanks. that seams pretty conclusively that it is a thing with the library. maybe there is a keep alive message that it is not sending that i need to look into.
Thanks. what version of the teensy were you using? i am wondering if it version specific or a problem with the built in midi library or something else. i am using a 4.1
Hi
I am having the same issue with sleep disconnecting the USB-MIDI and also have a device (Arduino Leonardo) that does not have this issue. id you ever find a fix?
