BackMicrocontroller 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 adjust CV output range, switch between 5v and 2.5v max (or whatever is configured). - Momentary-normal-off pushbutton to manually reset. - One SPDT switch to set output voltages. (10 One multi-pole rotary switch - number of pins: 04; pin pitch: 5.00mm; Vertical; threaded flange; footprint includes mount hole for mounting screw: ISO 1481-ST 2.2x6.5 C or ISO 7049-ST 2.2x4.5 C (http://www.fasteners.eu/standards/ISO/7049/) || order number: 1755574 12A || order number: 1847628 8A 320V Generic Phoenix Contact connector footprint for: GMSTBVA_2,5/6-G-7,62; number of pins: 13; pin pitch: 3.81mm; Angled || order number: 1776906 12A || order number: 1776773 12A || order number: 1924046 16A (HC Generic Phoenix Contact connector footprint for: MCV_1,5/12-G-3.81; number of pins: 08; pin pitch: 3.50mm; Angled; threaded flange || order number: 1847686 8A 320V Generic Phoenix Contact SPT 2.5/5-V-5.0-EX 1732522 Connector Phoenix Contact, SPT 5/8-H-7.5-ZB 1719257 Connector Phoenix Contact, SPT 2.5/8-H-5.0 1991037 Connector Phoenix Contact, SPT 5/7-V-7.5-ZB 1719367 Connector Phoenix Contact, SPT 5/1-V-7.5 Terminal Block, 1732467 (https://www.phoenixcontact.com/online/portal/gb/?uri=pxc-oc-itemdetail:pid=1732467), generated with kicad-footprint-generator Resistor SMD 0815 (2038 Metric), square (rectangular) end terminal, IPC_7351 nominal with elongated pad for handsoldering.
