Digital audio workstation software is often expensive. The heavyweight Cubase, Apple LogicPro, FL Studio, Adobe Audition, and Sony ACID Pro are each impressive software music production environments. Unfortunately, they cost hundreds of dollars and are released under a proprietary software license.
Fortunately, there is a good range of open source software that offers a free alternative. Here is my pick of the best. With a good background in music, talent, and patience, coupled with open source software you can be truly creative and innovative.
