The Mixer panel contains all associated Mixer controls plus Effects Routing Matrix buttons. All controls are duplicated for each of KR-55C's 11 instrument voices.

Volume- Sets the level for each individual instrument voice. Master volume is set using the Volume control at the right side of the panel, which is always visible. As always, keep an eye on the Master Volume Clip light when setting individual instrument volumes.
M (Mute) / S (Solo)- These are standard mix mute and solo buttons, respectively. Their LED's will illuminate when engaged, and can be combined in any fashion. The Solo LEDs flash when engaged - hopefully minimizing the occurrence of, "why isn't this thing making any sound?!?" scenarios.
Pan- All of KR-55C's instruments are inherently mono; the Pan knobs set the position of the instrument in the stereo field.
Effects Routing Matrix

Effects Send Buttons (Drive/Mod/Echo/Verb)- These toggle buttons allow KR-55C's effects to be applied to individual instruments in any combination. They operate like using send knobs to route mixer channels to effects on bus inserts, but instead of knobs, KR-55C uses buttons that send signal at "full blast." This configuration makes it really easy to, for example, add overdrive to the bass drum, reverb to the snare, flanging to high hats, etc. We think you'll find that the buttons make it really fast and fun to use (as opposed to twirling 44 tiny send knobs).
Trigger LED- These illuminate any time an instrument is triggered - these are the same as the Trigger lights on the Mixer page.
