pretty cool.
for recording a 4 channel soundboard matrix at shows get a rode nt4 stereo mic to go into the 1/8 inch stereo mic input instead of using the built in ones
you could def use the built in mics for recording your own music, but at shows it would be tough to put the deck where the mics would pick up best, and be near the SBD to get a patch, and also operate the deck at the same time.
