Need help with interface between PC and D20, using Cakewalk, Finale, Jammer, and Midiscan. Is there really a GM to D20 converter? Trying to play MIDI songs into D20 and then save to D20-formatted disk (with or without applicable sounds). I get as far as External Record with all eight channels blinking, but after the music plays the measure is still saying 001 and nothing plays back. HELP!!! (please)
