Help!...re: trad Taurus sound

Howdy folks-
Okay...we can overwrite on the first bank of sounds (WTF?!). The Taurus 3, Bass and Tuba all sound fine...but the traditional Taurus sound ALWAYS needs to be slightly adjusted to pulse less, or it sounds out of tune.
Has anyone else had this problem? If so, is there a way to fix it? I need to switch sounds during gig...and what a pain to have to bend over and adjust.
Thanks everyone.
