Just came across this gem of an Opensource program while looking at Osalt.org . Its probably not as good as FL studio, but I am very impressed with how much I could accomplish without ever playing around with this type of software. Could actually see myself start to produce some music using this software if I find the time. Anyway just thought I would point people in its direction, great software for people wanting to play around with music creation software.
