I use my kb as a monitor for me, and as such, I employ a slightly unorthodox method.
First of all - I need to use an outboard vocal harmonizer (Digitech VR) so I have to use a mixer. I route my vocals, a second mic and a stereo feed from my laptop into this mixer ALONG WITH the subouts from the kn ..... BACK INTO the audio inputs on the 7000.
This allows me to mix the volume and tone of the mics and MP3s/Midi files as they are played through the kb speakers. I send the drums and auto acc to the sub outs in stereo and I can now EQ them on the mixer in real time b4 they get sent back into the kb speakers, and then on to the line outs into my Bose PAS.
I play mostly left hand bass lines, so the auto stuff is not a priority for me and having a separate drum channel to boost, EQ and fiddle with is paramount to my happiness during a performance. When I do choose to allow the arranger to do the work, all those parts are routed through the sub jacks so i still have more control of the overall volume and punch as it is mixed with the rest of the KB signal.
I also use the mic input on the kn as a guitar channel. I think it sounds horrid for vocals, but terrific for my guitars.
The versitility of the mixer/kb spkrs is why I use this setup.
