Exactly how do I do it? I've played with my tascam MF-P101 and I know how to record on all 4 tracks but I don't know how to use the Power Amp ( It's a mackie 808S, 8 channel board) as tool for mixing all four tracks together. Could you help me out with the equipment that I have?:I have a SM58Beta that I record with and my speakers are two 200 watts EV's ( I also own a pair of monitors ) My keyboard ( Yamaha PSR-270) is used for recording drum parts, effects, and piano. What else do I need in terms of putting all on a track, mixdown!
