BackGoes up, opposite to expectation. Glide fix glide fix Notes from MK's PCB livestream Notes from MK's PCB livestream 3afa35e4b1 PCB initial layout, no traces One SPST switch to adjust CV output range, switch between 5v and 2.5v max (or whatever is configured). - Momentary-normal-off pushbutton to manually reset. - One potentiometer for internal clock signal (possibly external). Commonly called a "Baby 8", so called because it's a classic samba clave with rock/reggae rhythms on the footprint.
