recently i started getting into the midi mapping and submasters. The reason that i love it is because it is free, works with any interface and has some extremely powerful features. Have you tried running it virtually on your mac? i'm not sure what version of FreeStyler you are using or the system that it is running on, but ever since i have started using it a few years ago it has been nothing but flawless for me. i wouldn't recommend it for programming a light show with various fixtures. Makes sense because it is for controlling lasers. While Pangolin does DMX it is missing some key features that any DMX software should have.
