Ok, well I have the Studio Projects C1 microphone, and an Emu 1820.. no mixer, I've never done any mixing to any of my songs, but I kinda wanna start learning sometime. I'd like to know some add-ons to my setup.. I want things that'll better my quality. My budget will be around $300-$400. List anything that could help me with that amount of money. Thanks ALOT.
