There's one OP observation in this thread that, to me, stands out above all others:

Quote:

And finally, the MIDI Monitor shows no activity when inputting from the Impulse.


Normally, there's a simple explanation: Channel mismatch, bad cable, local on/midi off, something like that. Yet from the very first sentence of the thread, it appears the controller (among others) works with other midi software. Therefore, IMHO, the question is simple: why are the midi transmissions of a healthy controller not even penetrating the BB module? As Megafiddle and Mac sorta implied above, with no answer to that, what's the point in speculating on issues that lie further along the signal path?
