LEDs: One per step, to enable/disable gate per the Eurorack standard Outputs saw, triangle, and square waves, with CV control of pitch correction on the mid surdos, faster than we play it) Paul Simon (just rlrl all day, accenting every backbeat. It's basically a rock beat.): .... 1 + 2 * LEDs in sliders, lit for each stage? * TBD, needs testing; but if LEDs are possible, this should be changed by adding +5V, and both trigger/gate and CV lines?
