I thought it was 0-60. AFAIK, 0 = mute and 60 = max volume in the 
QuickNotes external I use on the Mac. Sound volume levels have gotten a 
little dicey under Panther.

Anyway, yes, the note parameters in a sequence have the volume, which 
is effectively a QT MIDI note setting. I would think that _either_ the 
volume of a clip or, for sure, a player volume, would be independent 
from each other.

Haven't tried, though. For sure, it would be worthwhile to see if I can 
fire the QuickNotes external from Rev.

It works from the data fork in a SuperCard project, but I don't know 
how to deal with it in a Rev main stack. Any help appreciated.

TIA,
Ken N.
