BackDescription have to be able to add picture 5082711a98 Add a front-panel PCB Send Account Recovery Email The build is pretty straightforward except for mechanical assembly, and one with an eye towards doing it all in one module with lots of analog drum voices; based heavily on Moritz Klein's work, but with buffering between (some) stages. Needs a TLC7524/AD7524 (a simple DAC that's still sorta analog) and a switch to disable clock (pause). SPST switch per step, to enable/disable gate per step. (10 Momentary-normal-off pushbutton to manually step. - SPST switch to adjust CV output range, switch between 5v and 2.5v max (or whatever is configured). Momentary-normal-off pushbutton to manually reset.
