hey guys,

has anyone got any good summing solutions perhaps even DIY for me to sum all my keyboards into 2 channels of preamp?
I would ever play them together really but just want them to all be on the same line so I wouldnt really need a resistor network i wouldnt think?

any thoughts? anyone got any designs that might work for me to build?

thanks

Matt

Can you solder?

This thread on gearslutz might also be useful

This link has more info - looks like what you want - it includes mono and stereo inputs.

And you're going to rip it apart for a SWITCH?!

How much do you want for the electrodyne console?

Swap you for a summing mixer...
