Buildguide:
Resonant Lopass Gate Build Document.pdf
by usage of a Rotary Switch - we needed six wires - we = have five colors - so we marked one of the white ones with a bit of heat sh= rink. We later removed the heat-shrink from the switch-end 'cause we realiz= ed it would be in the way - but we immediately soldered that wire to the sw= itch pad A. Here's how the wires worked out:
S1 - red - switch pad 3
S2 - marked white - switch pad A
S3 - green - switch pad 12
S4 - blue - switch pad D
S5 - white - switch pad 7
S6 - black - switch pad C

Bugfixing: (copy from naturalrhytm)
This board has gone through several revisions from 3.0 to 3.4 now. The b= asic build guide in the docs works for every board. The changes in each rev= ision can be attributed to adding the Euro power connector and optimizing c= ircuit traces more than any other factor. However, revision 3.2 of the boar= d requires one *tiny* jumper due to a circuit trace that got separated from= the ground plane when I beefed up the thickness of the traces. The= fix is to jumper a pin 5 of the mixer IC to ground (Which can be found on = pin 10 of the same IC). This error was fixed for revisions 3.3 for= ward.
