and A and B thrus

without any signal set the BIAS so that the LED has no colour

NOISE is an analog noise source in a very usable range which is near-enough white noise with some roll-off at the lower and top end of the audible range

used for inverting clock or gate signals

A little headroom has been added to create a nice saturation kind of effect if desired

Voxmachina SIGMA Function / Ramp Generator DIY PCB Kit Attenuator and A and B thrusA modern approach to the Serge ramp generator, provides v oct control and is also oscillating by default unless something is connected to the trigger input channel, provides multiple outputs, BP, DC and AC coupled outputs, also EOC and ! EOC outputs, when self patched for example from AC output into CV input can be used to modulate curve to be linear or exponential, also provides a switch to change modulation target to be ramp rise, both or ramp fall.
