I'm finally putting together the ensembles for my virtual orchestra in GPO 4. There are a couple of instruments for which I'd like to slightly extend the downward range:
Oboe Classical Solo lowest note from B2 to A#2
Trumpets lowest note from G2 to F2
Is there any way to do this besides applying pitch bend? My intuition tells me that if this is even possible, it would be by editing the appropriate .sfz file. However, I don't want to muck around there unless I know precisely what I'm doing, so any expert advice on the matter would be greatly appreciated.
