# Kicker

Kicker is a kick and bassdrum synthesizer.

It works by starting with a triangle wave at a certain frequency and gradually changing it to another frequency.

* **Start** and **End** knobs control the start and end frequency of the sound. Note that the knob is NOT ACTIVE if the LED is on.

{% hint style="info" %}
The Start frequency and End frequency knobs are only active if the LEDs under them are off.
{% endhint %}

* **Start from note :** When this LED is toggled on, the start tone will be the note played in the Piano Roll instead of the frequency of the start knob.
* **End from note:** When this LED is toggled on, the end tone will be the note played in the Piano Roll instead of the frequency of the end knob.
* **Frequency slope:** Change the steepness of the frequency envelope. Larger values let you slide for longer. Reducing it cuts off from the start frequency rather than cutting off from the end or speeding up the slide.
* **Click** controls the click/punch to the beginning of the kick sound.
* **Start** and **End Distortion:** Simple distortion envelope, controls distortion toward the start and end of the sound.
* **Gain:** Additional gain added to the output.
* **Length:** Length of the volume envelope
* **Envelope Slope:** Change the steepness of the volume envelope. The more the slope, the louder the initial value.
* **Noise:** Amount of noise that is mixed into the signal. Goes from 0 to 1, where 1 is only noise and no signal.

Kicker was created with drum synthesis in mind. It is best used in the Pattern Editor.

To get sounds which sound like drums you should set "Start knob" to a low frequency and "End knob" even lower. "Length" should also be quite low.
