The program's most likely 32-bit, since that's all the programming language allows for, but it seems like they've done everything they can to support third party programs in 64-bit short of recoding the entire program from scratch in another language.

I like that FLStudio are experimenting and moving forward with ideas, but I don't see anything that would make me use this over Ableton....... apart from the 'new novelty' factor.
