G-Storm Electro 2xADSR r1-2 Assembled Dual Envelope

These are the last units for sale as it is being discontinued. Grab them VERY CHEAP while supplies last! Please note: this design has a very small bias, say 20mV at full stop and not zero volts. This may produce bleed from very sensitive VCAs like Intellijel as reported by couple of users. 2xADSR works very well with my 2xVCA since it has a bias knob to correct the tiny offset.

2xADSR is a dual envelope module in 8HP Eurorack format.  Each envelope is an independent Attack-Decay-Sustain-Release linear contour. Each envelope takes a gate input, puts out a positive-voltage contour and a buffered negative-voltage (DC inverted) contour.

New for version 1-2

• Functionally everything is the same except the added capacitors + spdt switches for long/short response. Previously was only short response time. Also:
  
• added 100n filtering capacitors
  
• eliminated U4 by simplifying inverted output circuit
  
• added 4x 100R current limiting resistors to outputs
  
• Horizontal aligned components
  
• single screw post, previously was 2 screw posts

This is the assembled version. Included is a 15cm 10-to-16 pin ribbon connector. Just plug into your system and go!
