As an aspiring music producer, I use Audacity and Linnux Multimedia Studio. I know, the first of the two is pretty controversial, but to each his own I guess. Using these two software programs in tandem really help expand my sound a lot...and it gives me a bundle of options to choose from. My production style and approach is a little unorthodox, and as a result my music comes out that way. At the end of the day, I just try to make music that reflects who I am as a person, and I feel that right now(considering that I'm flat broke) these two free and legally intended to be free programs help me achieve that purpose.
