This module gives +/- 1V to 10V depending on the range knob location.

Original schematic is made by Niklas Ronnberg.

STRIPBOARD LAYOUT

2K trimmers actually do nothing, so you can omit them. Please correct me if I'm wrong.

SCHEMATICS

Original Schematic

Modified Schematic

1. ******SPST toggle switch added for kill-dry function

2. *55k(39k), **55k(39k) and ***20k(1k) resistors changed for level matching between high-pass mode and low-pass mode

3. ****10k resistor added for slightly cutting off low end  on low-pass mode

4. *****100k resistor added to 100k Level potentiometer in parallel for preventing the output from easily distorted when turning the pot past 12 o'clock

All things are done just to my taste, so please do not take it seriously.

This module is a unity gain MIXer and also a buffered multIPLE, so I call it MIXIPLE. Sound weird though.

SCHEMATIC

This schematic shows only a single MIXIPLE. If you are going to make a dual MIXIPLE like what I did, just simply duplicate it. Otherwise, you can use TL071 for U1 instead of TL072. 

STIPBOARD LAYOUT

I omitted diodes such as 1N4001 for reverse voltage protection. If you are worried about it, please add diodes.

POWER SUPPLY

I don't recommend to build this module, unless you are familiar with electronics. It could damage your other modules and also hurt you.

I used trimmers for gate threshold, envelope attack and decay instead of resistors and shunts.

As always, please double check errors before building. I checked errors on the stripboard layout several time tho.
