Hi

I was wondering if there's a quicker way of auditioning subsequent 
sound presets within an EXS24 library folder. Similar to a hardware 
synth 
where you simply rotate a wheel to go through many presets.

At the moment, each time I want to hear the next preset within a 
folder, I need to navigate (sometimes through quite a few sub 
folders) and select the next preset down. Very time consuming and 
frustrating when I have clients sitting in! Surely there must be a 
quicker way?

I use Mac G4 with Logic 4.7 + EXS24 (mkI)

Many thanks!

Matt
