I just got Finale 2007 and then I downloaded the Finale 2007c update.
So I'm looking in the Human Playback Settings and lo! I see two new setings for the Strad (which I have):
Enable Automatic Vibrato
I tried the Automatic Vibrato, but I wasn't very impressed. The vibrato starts after the note is played, and the vib. rate is exrtemely fast.
Is there any way I can tweak this? Thanks
