Summary

This is an advanced envelope generator for Eurorack systems. It allows voltage control of A, D, S and R, has 10 different state gates that depend on the envelope level at any particular time, linear and exponential curves, re-triggerable and self-looping.

The "state" outputs will output a gate signal during a defined stage in the envelope. For example, the "D" state gate outputs a gate signal during the decay phase.

These state gates can be used to drive other modules and allow users to build complex envelopes and rhythmic patterns.

The various looping modes (patched or switched) provide the ability to cycle and also operate as an LFO.

IMPORTANT NOTE

This is a PCB and Panel set only. A set of 2 high quality PCBs and 1 front panel ONLY are included. You will need to purchase your own components and build your own module. Comprehensive build instructions and BOMs are provided to help you source the components needed and we even provide links to shopping carts to simplify sourcing those components. Some product photos above show COMPLETED build.

Features

• Our most comprehensive envelope generator
• CVs for ADSR sections. Standard 0 to 10V but small negative voltages will shorten the A,D and R times
• State outputs:
• • A - On when attacking
• • EOA - positive edge of gate signal resets to 0, goes high at end of A
• • EOA (P) - short pulse only at start of EOA
• • D - On when decaying
• • EOD - resets to 0 when rising attack signal hits sustain level, goes high at end of D.
• • EOD (P) - short pulse only at start of EOD
• • S - On when sustaining
• • R - On when releasing
• • EOR - positive edge of gate signal resets to 0, goes high at end of R
• • EOR (P) - short pulse only at start of EOR
• EOD or EOR cycle mode
• Linear/Exponential
• Gate mode: When gate held, envelope follows ADS stages. When gate released, R stage begins.
• Trigger mode: When positive edge of gate signal, envelope starts A stage. The envelope continues with the R stage if the gate is released. If the gate is held, the ADS stages will be followed until the gate is released, in which case the R stage is entered immediately.
• Press Loop to start self-cycle/LFO mode. Cycle will start/stop/change shape depending on settings of ADSR
• For keyboard controllers with retrigger output, you can reset the envelope to the attack phase.
• 10HP Eurorack with our panel
