I'm struggling to understand the difference between the effect of CC#1 and CC#7, and the situations in which they should be used. I've just exported a midi file of a score created in Finale 2009. When I load it into Sonar I see that the strings' volume is controlled by a series of CC#1 controllers while the woodwinds have CC#7 controllers. My understanding was that ALL sustaining instruments used CC#1 for volume.
I've read what the manual has to say about this but I'm none the wiser. If anyone can shed some light on it for me I'd be extremely grateful.
