06eccf7d9c added the once through idea with commentary by 496e3e3344 Correcting changed filename in .prl * LEDs in many places might be more robust and easier to adjust CV output range, switch between 5v and 2.5v max (or whatever is configured). - Momentary-normal-off pushbutton to manually step. - SPST switch per step, to set clock rate (if onboard clock is used) (rv11 // 1 for manual step (sw13 // 1 to 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.
