For Christmas I got a powered monitoring system for my Yamaha Electronic drum kit (MS50DR - Monitor Amps - Electronic Drum Accessories - Drums - Musical Instruments - Products - Yamaha United States) Works great for monitoring myself when playing drums. I have this thought... For live performances with the band, I would like to take the line-level monitor mix from our PA and mix it with the drum signal so I can hear both through the MS50DR. That way I can have my own personal mix of myself and the rest of the group. All I really need is a basic line-level, 2-source (4 channel) stereo mixer. Thing is, I'm having trouble finding something that basic. Does anyone have a suggestion? P.S. Ideally I'd like just 2 sliders - 1 for each stereo channel. Or, better yet, just 1 fader that goes from just me at one extreme to just the monitor at the other, and then blends the 2 in-between. Dunno... My expectations are pretty specific. Maybe I'm best off just building something.
