I just downloaded the demo version of Brass to try out myself instead of guessing of what its capable to... I thought it would work out fine on an old PC version of Logic 5.2 as well... but the only thing that happend was that Brass didnt accept my soundboard. No settings available would make Brass sound even a little bit... just crashed my whole system.
All the serials and codes were put in as told... so thats not the problem.
