I understand that. Silvertones made it sound like the SuperTracks will play through ST without first loading the desired instruments. This is not the case on my system. If no instruments are loaded in ST, no sound will play - even loading a SuperTrack style.

Being that I use the same set of instruments for most songs, I created a group of instruments that I load into ST and they stay there until I unload them. Songs that don't use those instruemts are manually assigned specific instruments within the song.
