Blue Lantern Simple ADSR V2.1

The Blue Lantern Simple ADSR Looping Envelope Generator V2.1 is a redesign of the original, featuring a new front panel and a CV input for velocity control over the level output. The module is a four-stage envelope generator with a dedicated Time knob that alters the length of the loop. The Simple ADSR is useful for controlling VCAs, Pitch CV, VCOs, and Filters.

Additionally, it contains three different modes: normal envelope mode, looping mode, and gated mode. In the final mode, the looping function is activated when the gate input is high.
