Sampler problems

[Ginevra]

I have come across two issues since upgrading to Finale 2010a & GPO 4 - both relating to the pipe organ:
1.   In the Kontakt interface you could "tune" the stop to raise or lower it's range; ie. taking the 8' flutes down an octave to create a 16' pedal.  I haven't been able to discover how to do that w/ the Aria interface.
2.   I'm finding the organ is not responding to dynamic expressions during playback - everything seems to playback @ about a mf.  I've tried deleting continuous data, etc. as well as deleting and reinserting the expressions to no avail.
Anyone else run across these issues?  Any advice?  Thanks.
