Currently I have a powered Yamaha mixing desk, microphones etc., essentially all the gear I need to play live. I want to know what equipment I can add to this desk so as to have a home recording studio. What recording equipment can I add to this desk so I can utilise its twelve track capacity. If I buy a four track am I essentially by passinf the mixing desk? My theory is that if I add a multi track recorder to the outputs from this desk have I in effect got a twelve track recorder? Any advice would be invaluable.
