EXS 24 Logic Sampler Users Group

OK, I know there's a way to quickly jump through instruments' settings and
the EXS24's instruments themselves, but is there any way to quickly jump
through PROG patches in various VST instruments? This is driving me crazy. A
good example is the free VST synth called Crystal. It's painful to have to
click and drag all the time. Seems like I could create an environment button
that moves to the next patch by controlling some kind of program change, or
am I way off base here? Thanks. -Jer
