I'm trying to configure my A-880 with your editor but I came across some problems.
I have an Elektron TM-1 as my test midi interface.
I connected TM-1's input to A-880 MIDI OUT 1 and A-880 MIDI IN 1 to TM-1's output.
I've configured the editor to enable TM-1 input and output.
I've also powered on the A-880 with INPUT/BANK button number 1 pressed so my Control CH is 1 from what I've read on the manual.
When I'm trying to "read" A-880 from the editor the program stucks at "Request Send".
Any idea of what I might be doing wrong?
