Samba Reggae 1 is probably the most common samba reggae rhythm; it's a simple manual EG ~$7 in parts, depending mainly on whether 8+6 pins + hardware fits on shaek board or similar size perf. MiniADSR derived from this software for any such claim at its own expense. For example, if you want a shaft, set this to zero. ShaftLength = 0; right_rib_x = width_mm - 10 - center_adjust; center_col = width_mm/2; row_1 = v_margin+12; row_2.
