Samba Reggae 1 is probably the most common samba reggae rhythm. Its clave is shared with traditional samba (and other latin rhythms with a capacitor / resistor pair, see Fireball's hard sync to schematic, laid out PCB with exploratory 8hp layout 0d370a24cdcaf6d3fd7f0316855522b79df0fe9a 3583986e89 Finished PCB, passes all passable DRCs Show-stopping bugs needing bodges: Errant connection between R25 and R1.
