that is great news , been using groove agent since it first came out way back in the day , upgraded to groove agent 2 and loved it . Im now on groove agent 3 and love it , so i will definately be upgrading to groove agent 4 , great concept , nice and easy and highly effective .Cant wait for the fourth installment !!!
Bring it on !!!
ps
some expansion packs would be great to , ie , film and classical score expansion , ambiant and chill drums expansion
maybe even a random fill + groove genarator
