Herbs and Stones Legs - Analog Kick and percussion synths module

Legs is an analog kick and percussion synthesizer module in eurorack format.

It is based around a triangle core voltage controlled oscillator and a two levels voltage controlled saturation stage.

Each parameter has its own dedicated CV input, when a control signal is patched into any of the inputs its corresponding knob will act as a CV attenuator.

Two independent gate/trigger input with level control can be used to create accents, pattern changes and generally work on track dynamic.

Each of those inputs has its own trigger conditioner circuit so it can accept different types of signals, not necessarily rectangular waves or short triggers (its threshold is set at +2.5V).

The CV inputs expect voltages in the 0-5V range (a negative voltage won’t damage the unit and won’t affect the sound).

From rumbling low end basses to distorted warehouse window-breakers, Legs can synthesize it all.



Parameters:

base: sets the base frequency of the voltage controlled oscillator

drive: sets the amount of distortion

drive switch: sets the distortion amount range

length: sets the duration of the percussion sound

bend: sets the curve of the envelope generator that controls the oscillator frequency

bend amount: sets how much the envelope generator affects the oscillator pitch

base CV input: CV control for the base frequency parameter

length CV input: CV control for the length parameter

bend CV input: CV control for the bend parameter

drive CV input: CV control for the distortion parameter

trigger A level: sets the level of impact of trigger A (to create accents and work on dynamics)

Trigger A: input for trigger A

Trigger B: input for trigger B
