When I try to send wavs to my DMPRO using Soundbridge, I get an error that the synth was not found. I am using a P3 laptop with XP, and EDIROL UM-1 midi device,I have my midi cables connected, etc. The first time I started the transfer, the DMPRO said "RECEIVING MIDI DATA" for about a second before returning to the name of the drumkit. Ever since, I can't connect. ????
