G-STORM ELECTRO 2xADSR Dual Envelope Euorack Module Demo

In this quick demo I show my new 2xADSR DIY Eurorack Module. 2xADSR is a dual envelope module in 8HP based on the Arturia Minibrute. I am playing midi from the Axiom49, using the Pittsburgh MIDI3 module to convert MIDI to Pitch CV and Gate. The gate feeds the 2xADSR. The envelope contour is sent via a buffer mult to control both the Tonus VCF filter cutoff AND Bastl Skis VCA. I interchange the trigger input with the Varigate4 as well. I'm doing all this mainly to show the linear contour characteristic, how long the attack and release can be, and how snappy short decay & release sounds.

The BOM and Schematics for this project can be found on muffwiggler.

2xADSR is a dual envelope module in 8HP Eurorack format based on the Arturia Minibrute. Arturia has shared the schematics openly on the internet, so it would seem reasonable to have adapted a fun DIY panel/pcb project for educational purposes under fair use. Each envelope is an independent Attack-Decay-Sustain-Release linear contour. Each envelope takes a gate input and puts out a positive-voltage contour output. I have added a buffered negative-voltage (DC inverted) contour to the circuit. Surface-mount soldering required, I would not recommend this as your very first SMT build - maybe your 2nd or 3rd SMT build though. 1206 resistors and 0805 capacitors, it uses all very affordable and easy-to-find parts as found below in the BOM.

Module Depth: 22mm
Current Measurements: 27mA/+12V, 3mA-12V, 0mA/+5V (not used)
