there are dynamic \"layer\" instruments. Check the \"long notes\" gig files. They usually have a few variations of dynamic layers.
These use the modwheel to Xfade between dynamics.
BTW I actually find I dont use these as much as I do on other libs. I use the crec/dim samples alot more. As well as the legato stuff. Its a weird library thats breaking some of the habits I\'ve built up.
Ed, you need to record the samples that way. So you record for instance p, mp, mf and f samples of strings and then do an x-fade between the layers in GS. THere is an x-fade editor in GSEdit for this purpose.
