PROBLEM #1 Reface DX connected to new Native Instruments Komplete Audio 6 MK2 via midi breakout and midi in/out cables. Reaper has NO signal from the Reface DX, though the mic and other keyboard connected via XLR on the the laptop, are coming into Reaper just fine.
DX breakout cable midi out is connected to Komplete 6 midi in, and Komplete 6 midi out is connected to Reface DX midi in on the breakout cable.
What could be the problem?

PROBLEM #2 I have a Crumar Mojo 61 with upper and lower keyboards. A fabulous instrument built in Italy by a coder. I have an MJU from Crumar which is an arduino device to power and allow the lower manual to act as a full midi controller keyboard. With the MJU midi in/outs connected to the Reface DX in/outs on the breakout cable I have NO sound from the Reface when it is supposed to be controlled by the Crumar keyboard.
Is this a midi issue with the Reface DX midi signal?

Thanks all
