I am the drummer in a small band and we are looking to get into recording. i have the Lexicon omega recorder, but it only records four tracks at once. We have a total of 7 drum mics, 1 mic on the guitar amp, and 1 vocal mic totaling 9 inputs. Is there any way to hook all this up to a 16 channel mixer and then hook it up to the omega recorder? Any help would be greatly appreciated.
