Add jlc constraints DRC; replace order number text Things best left to external modules: CV-controlled CV offset module - add a global/master pitch control/modulation function with a more complex module, several variations on the GitHub page (they'll have "@ something" after them) and download them as separate sheet ## Photos [to be added] ## Documentation: * [Schematic](Docs/precadsr.pdf) * PCB layout: make power connection traces larger; MK uses a ground plane.
