It is full package focused on Progressive Rock genre but it could also be used for Cinematic music as well as for Electronic productions especially those with dark sound character and those which rely on warm analog sounds.
The first soundbank of this collection is a generic journey through the Golden Era of music and it consists of 25 Synths, 20 Long synths, 20 Leads, 15 Basses and 5 Airy Synths. Prog Rock 2 is focused on two opposite sides of synth sounds with 50 Huge synths and 50 Soft synths. Prog Rock 3 has 70 patches that dive into the early 70s soundcolors and it is full of nostalgia. Finally Prog Rock 4 contains 30 organ sounds that fit with all the other Prog Rock packs and fills the blanks to create a multidimensional collection dedicated to the genre.
