I'm a GOS Lite user. I bought it about a year ago. I don't know if I was supposed to register it or not but I've never received any information about updates.
Anyway, I've noticed some references to updated .art files for this library (and regular GOS). Could someone point me to those on the Garritan website? I emailed Gary but he seems a little busy right now.
I'm sorry I don't remember where this information came from. However I was able to click on a posted url link that took me to the files at your website. One particular .art file added "attack" to the Full Strings Lite.gig through one of GigaStudio's 2.5's GPC sliders and were fully downloadable. I didn't need that capability at the time so I forgot about it until now. The link stopped working so I deleted it... wish I had it now to prove this!
