    Hey guys, i got one question.
    if you read through the "launchpad programmers reference guide" you will find following information
    "Select the grid mapping mode Decimal version 176, 0, 1-2.
    1 X-Y layout (the default). 2 Drum rack layout."
    in my new patch ild like to use the drumrack layout.. so i need the msg (176, 0, 2)
    but where to send it? to a midiout object?
