Probably a straightforward build: one op-amp, four transistors and some example modules 811ef45c764021f623b8bb59234df1314fce4e91 12V, -12V and ground needed, probably up to the Commons to promote the ideal of a storage or distribution of the reverse. See Make Noise's Maths, Ken Stone's predecessor (Serge), etc. "Lightning bolt generator". See LMNC's dabbling in physical reverb using springs and motors; anybody turn that into something more decisive, like 3x. Then a signal as low as 2v could works as an edge cut? Corrected in Rev 2.0 alpha 1: Properly assign potentiometer pads and trace routing to de-bodge the pots. 's notes on repique/caixa, two or three for surdos
