Transpose stops working after exactly 15 notes

What range of notes are you using?
What's +/- transpose are you using?

I've reproduced this problem just using a single note, but the whole range of notes I'm playing is 40-43 (according to the midi monitor)

Can you look in the MRCC in the tools there is a MIDI monitor, it should show any MIDI data being sent out, that should be enough to see if the note being sent stops being transposed, or if it's happening in the destination device. I am pretty sure it will only show MIDI data that is being routed so if we want to double check its actually sending the right notes, we can do something a little trickier and take the output of 10, route it back to another input, lets say 5, then route 5 to output 9, and look at the MIDI monitor. If we send note 60 for instance and transpose it to 72, it should say 72 out 10 and then 72 in 5 and 72 out 9 in the monitor each time we press the key.

According to the midi monitor, the first 15 notes I play are 28-31, then from the 16th note onward they become 40-43.

I tried the other test you recommended, but the results don't make any sense... It shows the input and output notes being identical and not transposed, and then after 16 notes they both shift up by an Octave not transposed. I only have transpose 1 on the first routing from 1 to 10. 

This would suggest that the keyboard itself is dropping an Octave after 15 notes... Except that I know for a fact that it doesn't. Like I said in my first post, this issue doesn't occur if I plug the keyboard directly into the MPC, and the MPC's note monitor doesn't report any shift.

One more note... Those test results would also suggest that transpose is doing nothing at all, which also don't believe to be true.
