Step 4Solder + Screw
Hopefully, your new case will fit all the components you've purchased. I kept a drill handy in case holes needed a little prodding.
Screw in all the sliders, knobs and click in the buttons, then clean the components and bolt threadings well, and apply threadlocker generously (or as instructed).
Read the Doepfer manuel thoroughly, it's well written, and covers all you need to know about the wiring process!
The board has a +5v line, a GND line and 16 control input lines from 2 ribbon cables. For each control element, you put the +5v in and then as you turn the pot or slider, the output changes from between 0v to 5v (except in the case of a pushbutton where it will go from 0v in off straight to 5v in the on position). The control input line senses the current voltage and converts it into a midi value of 1...127.
Since our design calls for 25 different controls (9 EQ pots, 9 EQ kills, 3 volume sliders, 3 pushbuttons, 1 headphone volume), but the Doepfer we used only allows for 16, we needed to do some creative merging;
Run the circuit for the EQ lines like this: +5v --> EQ Kill --> EQ Pot --> control line input: this way, we combine the EQ kills and pots onto the same control line!
Once all your control elements are in place, cut & strip the lengths of wire between each connection point & solder up!
