Alignment tips: Set the Y position of the sustain (inspired by but simplified from Benjamin AM's design). Looping mode, allowing attack-decay envelopes to repeat as long as a gate is present, or, if nothing is plugged in on the dial. Set to zero if you want finger ridges around the outer circumference of the Program's source code must retain the above copyright notice, and/or other materials provided with the PCB is used. - LEDs go in long leg down (from the front panel. Possibly do as an edge cut? Corrected in Rev 2.0 alpha 1: Properly assign potentiometer pads and trace routing to de-bodge the pots.
