    I can successfully send entire patches to the THR10 now and the solution has been running for hours without any stability issues. Mission accomplished. Thanks again Paul for your great support.

    The only changes I ever made where those you advised me to do:

    1. Reduce Speed to 12MBit/s according to Post#13. This change didn't make any difference, so I rolled it back later.

    Hi Paul

    The Output is huge. I made two tests:

    - With small buffers I didn't get any output for incoming SysEx messages
    - With large buffers I got the above output

    Just a thought: I think to remember from another forum discussion that the THR10 automatically sends out all its settings when you connect it to a host. That would be 261 bytes for the patch, 18...

    Hi Paul,

    Sure, I can do this when I'm back home.

    I just reviewed the changes you made to the library two days ago. You introduced a new class MIDIDevice_BigBuffer. May I suggest to solve this...

    We're getting close. With your suggested change in midi.cpp, I can receive data from the THR10. A bInterfaceClass of 0xff probably makes sense, because the THR10 also has an USB audio interface that...
