For this setup I ran all the 16 synth’s into two 8 channel stereo mixers using 2 16ch snakes. I took the stereo mixes of each rack mixer and ran them into 2 stereo channels on the main mixer. Using the mute buttons I can easily select which synths to blend for unique single tracking sounds. This is helpful if you don’t have 32 available inputs for all your synths. During Installation custom ears were made to double mount the two mixers on the underside of this table becoming part of the main mixer sub mix controls.
All of the keyboards are running through a mixer live with effects, looper and recorder attached. Great for idea generation and loop builds. This room has the following listed keyboards. Yamaha SY-22, Yamaha DS-55, Roland D-50, Ensoniq ESQ-1, Korg DW-8000, Akai AX-80 & Oberheim OB-12. Effects modules are Yamaha PSE 40X double unit, Multiple Rackmount Effects plus three other custom stomp box pedal effects boards. PA Sound is 900W through 4-15″ woofer box enclosures with horns. A Marantz Solid State recorder is connected.
