From the post
I needed something like this myself, so why not share. I've been thinking about building a console for our keyboardist. She has this amazing wooden 70's Casiotone that i dugged up from trash and it worked. It's default sounds are pretty bad, but using the organ sound and putting it through Skreddy Lunar Module Deluxe makes it nothing less than a perfect punkrock organ. She also has MicroKorg XL in her setup, so i thought i'd build a two channel active mixer for the organ (with fuzz) and synth - then take that to active DI, so she'll have just one balanced output and total volume control from one console. This is snipped out from GGG's 4 channel mixer schematic. If anyone really needs more channels to this, i could draw one with more...
Here's the revised version of the two channel version of this mixer. One resistor change will add more output level...
