Quad ADSR

Maker	Jordan Aceto
Type	Four digital ADSR envelopes with encoders and a seven segment display
Mounting	SMD
Width	17 HP
License	Proprietary (No licence published)
Difficulty	🌋 Fine-pitch SMD

An STM32 generates the envelopes and four encoders set the parameters. Any envelope can be locked to a master so all four share settings while still triggering independently. The README marks it a work in progress with known first revision issues, and it uses 0402 and 0603 parts.
