I used FL Studio 12, which is a DAW (with piano roll, etc.). I only used the sound sources provided in the pack, because that's what a rule in the remix catogory. Luckily, in that pack the Funk Drummer breakbeat from James Brown was included. So technically they are live, but they are just samples which I edited a little to make it more smoother and without the voice. Also edited the pitch and some other minor things a little for better smoothness so people wouldn't notice I cut the samples in parts and glued them toghether. Did that with Edison and then exported as samples.
If there's anything other you'd like to know, feel free to ask.
