PS: Glenn's above link also includes a Tyros 'instrument definition' file for "Band in the Box" as well. Just installed and it's wonderful to now have access (from both Band in A Box & PowerTracks) to ALL of the Tyros' terrific internal instrument voices now, and not just the GM ones. MANY thanks to Lanny Rosicky for both his work and generousity in sharing these files with the Yamaha Tyros arranger keyboard user community. - Scott
