@dsv101 - Haha, thanks. This project has been ongoing for quite some time, I just have been busy with other things.

@Krubbz - Thanks, I'm glad people are interested in this.

I'm down with this idea.

Good luck with this project, It is strange you started this when you did. Just days after me and cooshinator had a remarkably similar Idea.

@threesecondsecret - At the moment it is planned to have 4 stereo channels, but if people end up wanting to cut costs, it would be fairly simple to lower the number of channels.

This sounds so cool at the moment are you planning to have 4 stereo channels?

@Downstate, Russellian, Lavar - Thanks guys! Hopefully I'll have a working prototype to share soon

Same here!

Yeah, I can't wait to see where this goes!

this is an awesome project ! keep it up sir !

@MagFitch - Thanks! I'm hoping to have a working prototype in the near future to show you guys.

I quite like this, keep it up!

I've posted a design mock-up for the mixer on my tumblr

Check it out here:

@infradead - The jumper cables would probably be easiest for configuring the mixer, but my only thought is that you would still have to have all of the modules present in the mixer itself, regardless of whether or not you are using them. The way I envision it is having separate modules that would fit together in order to reduce the components needed for the mixer, meaning if you only need a mixer with no EQ or FX sends then you would only need the base mixer module and none of the others.

i have some modular synth modules that have expansions.  they use jumpers cables and to hook up on the back.  works pretty well and keep it clean and out of the way.

@Auxide, Downstate, and herr_prof - Thanks! I'm glad that people are interested in the whole modular design thing, I'll try and get some sort of mockup done soon, and I'll work on getting a prototype built as soon as I get the parts for it.
