Envelope Generator

This module is designed to replicate the user interface and the behaviours of the “Transient” envelope generator from the ETI 4600/3600 and later Maplin 5600/3800 synthesizers.
The ETI transient controls had a range of 5mS to 5 seconds. In this module they all have a range of 1mS to 10 seconds in four even decades, i.e. 1-10mS, 10-100mS, 100-1000mS, and 1-10 seconds.
To simplify the circuit, a Microchip PIC processor has been used. The PIC code has been developed from the Electric Druid LOOPENV1 Looping ADSR, and is released under a CC BY-NC-SA 4.0 license.
While the Transient is basically an ASR (attack, sustain, release) envelope it is capable of some envelope shapes not easily achievable with other envelope generators.
