I know this is NOT a SampleTank forum, but there are folks here who might know...

In ST 2.5XL, is there a way to set a global transpose?
I'm putting together a system for live use and the band detunes a 1/2 step.
Roland PK-5 doesn't have a transpose function. Other than going into every patch individually to change the pitch, is there a setting to do this globally?
