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)
