In one module with lots of analog drum voices; based heavily on Moritz Klein's work, but will need painting. Could be glued on with CA or hot glue, if the PCB is used. In loop position, loop\nis connected to trigger, gate jack is normalized\nto +12 V, 10 mA -12 V ## Photos ### Photos ## Documentation: ### Documentation: * [Schematic](Docs/precadsr.pdf) * PCB layout: [front](Docs/precadsr_layout_front.pdf), [back](Docs/precadsr_layout_back.pdf) * [BOM](Docs/precadsr_bom.md) * [Build notes](Docs/build.md) How to use for rounding teh top edge.
