Running Windows 10 on PC. I'm running Notion 6 from an external drive with all folders in this drive. In score Setup, Notion instruments, if I select an instrument that is not greyed out I get the sound when placing a note. Piano is greyed out (in keyboard/harp) though Piano.prox is in the Bundles folder as is Harpsichord.prox which is not greyed out. If I select piano I get no sound when placing notes If I select Harpsichord I get sound when placing notes. It seems most of the instruments in the bundles folder are greyed out and unavailable... help!
