Page 2 Things to note on the photo below: 8 way ribbon between the two PCBs Ground bus connecting all sockets and terminating in the CV PCB Gnd pad. CV inputs x 4, solid core to CV PCB pads. Glide LED, the 1K CLR (inside the black heatshrink) connects between the LED anode and the Glide input, the LED cathode connects to the ground bus.
Page 3 Glide status LED Glide is ‘always on’ providing there is no jack in the Glide input socket as the normalise lug of the socket receives +5V from connection to the Main PCB, the glide amount being determined by the Glide knob. Inserting a jack into the Glide input socket disables ‘always on’, and Glide will only occur when the Glide input socket receives a +5V gate signal.
