Next weekend I'll be playing a gig and we just bought a relative cheap mixer to use as "main" mixer. we connect both my electronic drumkit and my s4 to it. we bought the Numark M3 which had killswitches, that is actually the reason I bought it. But it also has transform buttons, I just googled to see what these are, but all I found were lame answers like: "they turn down the suck and turn up the awesomeness" xD So could someone exlain to me exactly what these buttons do? and is the Numark M3 a decent mixer? the audio just has to go through it, the actual mixing will happen on a s4. Thanks!
