Keybump

Fully voltage controllable ADSR/LFO with built in VCA and timeshift

Keybump

Keybump is a 10HP fully voltage controlled envelope generator for Eurorack synthesizer.
Each control knob has a dedicated CV input.

Keybump can be used in lopping mode for voltage controlled shape modulated LFOs. Or, Gated Loop mode which will loop for the duration of a high gate.

Additional features:

Clip button: This will clip off the top of the envelope shape for an added punch effect. Great for quick percussion sounds.

Curves button: altering the response from linear to exponential

Timeshift: Timeshift will hold the ADSR shape set by the panel controls and compress the shape over time. Fully counter clockwise = x1, fully clockwise = x.01. Patch example: Set Runner to loop mode, patch a key step’s aftertouch cv to control “Time” on Runner. This produces interesting variations by way of pressure expression.

Level: Level acts as a VCA for the overall amplitude of Runner. This is perfect for using with a keyboard’s velocity output.

Please Note: CV inputs override internal voltage connections. The panel knobs become attenuators for incoming control voltage.
