Keybump is a fully voltage-controlled envelope generator for eurorack modular at 10HP

Three primary modes of function:

ADSR: classic four-stage envelope generator with CV control over each ADSR parameter, amplitude, and timeshift. Timeshift holds the general envelope shape and compresses/expands the modulation over time. Timeshift gives quick and simple CV and manual control over varying speeds of the evelope.

Gated Loop: the envelope will cycle through each stage continuously, so long as a high gate is present at the gate input

Loop: continuous cycle [LFO] mode, the module will cycle through all stages at the selected amplitude regardless of gate/trig inputs. Adjust the Timeshift knob clockwise to reach low-audio rate modulation 

Timeshift knob: you can adjust the entire module's temporal response with the Timeshift knob. Adjust the module's time range from x1 (counterclockwise) to x.01 (clockwise). For example, the attack knob in conjunction with the Timeshift knob can range between 1 mSec to 10 seconds.

Level: extremely versatile amplitude control. Try patching velocity from a keyboard controller into level for very responsive envelopes

Shape shift button: changes the response curve from linear to exponential
