Hey so basically, I have a background in music and love making music electronically. Thanks alot 'pulse beat' and Dj jaz , that was very helpfull. However I still do not exactly understand why people use vinyl and Cds, is it because on cds and vinyl it is bigger and therefore easier to control, and Dj jaz, why would I get board with a midi mixer? I am looking in the genres of hardstyle techno, and rap. Also why do people buy units of a mixer system plus 2 CD decks etc, when one can just use a midi controller which has everything. Lastly, with any any midi controller mixer system can change tempo add effects etc.? Thanks Alot!
