Hi Susan
I only found out that GEM is a complete setup including the GPO Studio in stead of a stand alone soundfont bank.Also there is a USD 25.00 discount for owners of a Mackie product,like Traktion for instance.
Not being a serious composer like Sherry,GM,Fred and Tim( to name a few)
GEM appeals to me, promissing better sounds than the soundfonts I am currently using for messing up old songs I used to play with the band and "constructing" new songs with Composer to play along with my bass guitar.So in my opinion, GEM might appeal to those users of Notation programs who are not seriously engaged in composing great orchestral works.If you didn´t already notice, an excellent user guide for installing and working with GPO and Notation Composer( by Mark and Sherry)is available and can be downloaded as a PDF file (Garritan website)to help us along getting nice sounds.BTW, what kind of instrument(s) are you playing ?
I have decided to go for GEM and give it a try.
Regards
Djim
