looking at this and thinking how can make it do more for the space, the most you got is 1P12T what would give you 11 Different tones and a ByPass, but also means 11 Caps So i looked at a 16 way switch with 5 Input/Output and playing around
see what i could dow with 3 Caps all linked together, changing the point of Input/Output's along then line Got about 14 different types, so added another cap over the whole lot, shunting the values up by one value means i got 15 values (some a bit same ) and a Bypass So a Design i have for a Log Capacitor Switch, in this case (tho will need to change as values dont suit what you can get in Caps) 1nF-22nF, with 14-15 Different Values and Bypass and To Explain the Colours Above, GREEN was ONE I/O and RED was the other I/O (Pins D and E) ABC where the Legs in between the CAPS, Blue/Black where Direct LINKS to each other (to by pass a cap) Light Green was used for when it didnt matter if it was Green/White (Blank). The WHITE O where VIA holes to link one side of the board to the other to have Tracks go to where needed to be. Also not that Row D and B are 180' out of phase, and why things got moved around.
Sadly i had to draw this in a PCB software, so Line on line of drawing at very small level so looks bad I do hope to find a Good FREE CAD Software that i can use to bring in better drawings
hope to have it Made next month and after that test it out
