Transpose midi input question

[Jesse Johannesen]

No that's exactly what you can do. The CC for Key is 73, and sending a value between 1-12 will select a Key change. They progress from C following the circle of fifths (1-12; C, G, D, A, E, B, F#, Db, Ab, Eb, Bb, & F). So to transpose to G minor you would send a value of 2. You will need to make sure you are sending that CC to the NDLR Ctrl channel, however, as that is the only channel on which the NDLR is listening for these messages.
