Look up onNLC Doof - I built this module this summer. It has been used only a handful of times, it's a very fun module to play with. Everything works perfectly, comes with a power cable.From NLC Website:DoofDescription/Usage8hpDoof is a drum module. The design is typical of early 80s drum modules, best to look at the schematic to grok it. In this design, the VCO is a trimmed down version from the NLC dual OTA VCO and the VCA is the same as the ones in the NLC Matrix Mixer.
