Hi Otto.
I'm going to give it another go when I get back from work (Only 3 hours to go !). Just to make sure I'm going to be methodical for a change
I will do it in this order:
1. Connect usb plug to PC and midi in plug to midi In socket of BFD
2. Switch on PC
3. Switch on BFD
4. Open REW and go to settings to see if Midi cable is recognised.
If it doesn't work I will:
1. Close REW
2. Connect midi out plug to midi in socket of BFD
3. Open REW and check.
I'll let you know how I get on.
Let me know if I'm missing anything above!
