I do not produce, only mix.
I also make free house and electro podcasts, available in Itunes.
For mixing: MixMeister Fusion (mmf)
For editing with jingles and inserting my voice for podcasts: Camtasia Studio
For producing: I once tryed Fruity Loops (FL studio) but it ain't my thing.. Its great for the peepz who can work with it but i'll stick with mixing;)
