    thanks for shooting again :-)

    i just tired with arduino 1.8.15 and teensyduino 1.54, the problem persists.

    i hope this helps to narrow down the issue.

  6. usbmidi host on teensyduino 1.8.13 vs. 1.8.19

    hi there,

    i have some usb-midi host sketch that works on 1.8.13 but doesn't work on 1.8.19 (it compiles but there are a lot of hanging notes etc.)

    the code runs on a teensy 3.6
