Here's the layout of the DCO 1 controller prototype. I intend to design and build individual controller sections for all the synth "modules" like the envelopes, LFO's etc. These sections will be hooked up to the I/O expanders and ultimately the CPU.

UPDATE

The build is coming along nicely. The stripboard traces have been cut, resistors and switches have been soldered in. But I've run into trouble with the last 3 potentiometers.. I shorted a couple of paths and for some reason I wasn't able to fix it. So I'll just have to remove and re-solder them back in place tomorrow. After that, I will put in the wiring, the I/O pin headers and finally the blinkenlights.

Nearly done! Áll that's left to do is wiring the 'outputs' from the switches and pots. Ive decided to drop one of the pots because i just couldn't get it soldered in the right spot. Perhaps i'll move it to a bit of unused stripboard real estate when i'm done with the wiring.
