What mixer, presumably digital, would everyone recommend for a small corporate events type band consisting of the following: Roland TD-25KV V-Drums either using the Roland brain, or Superior Drummer 2.0 through a laptop and an audio interface (either option goes in direct) Bass direct Guitar direct Keyboards direct Sampler 1 direct Sampler 2 direct Backing tracks from laptop and an audio interface There are no stage amps and no vocals in this group. The drums and keyboards would ideally get two channels each, but if they have to live on one channel each (mono) that would be just fine. The live mix will be in mono, so having them go in mono might even be ideal. I also need to have AUX/monitor sends on each channel, and the ability to construct four independent monitor mixes for each players' in-ears/headphones. This needs to be independent from the FOH mix which will go out to powered speakers (i.e. a powered mixer is not required). I'd like to be able to control everything from my iPad such that I can set a loop on my drums (I'm the drummer, not the bassist in this group) and have the band play to it while I go out from to check the FOH mix periodically through the night. The Behringer Air and Mackie DL mixers both seem like potential options, but I'm very new to the live sound world and wonder if I'm even heading in the right direction. Keeping cost down while still maintaining the minimum channel count and the ability to have four independent headphone mixes that are separate from the FOH mix are the most important aspects of this mixer. Thanks!
