PCB for Eurorack AD/AR envelope generator (2HP)
THIS IS A BARE PCB! IT IS UP TO YOU TO SOURCE APPROPRIATE COMPONENTS, BUILD THE MODULE AND FABRICATE A PANEL FOR MOUNTING!
CONSTRUCTION REQUIRES THE USE OF SURFACE-MOUNT COMPONENTS
A cut-down version of the DV3 envelope generator - the principal difference being that there's only a single channel, rather than two, and it fits inside 2HP so if you've got an awkward gap in your case then you can fill it with something useful.
If you want a nice, simple envelope generator aimed at use in percussion patches then this is it. Better still, you can also use it as a slew limiter if you're so inclined - bear in mind, however, that the response is exponential, rather than linear.
Attack and release values are independently controllable, and if you're unhappy with the default settings then you can easily alter them.
You can get the BOM and schematic from here: https://bitbucket.org/yorkmodular/ar2/src/master/
