# 5.5 Kicker Kicker is a kick and bassdrum synthesizer. ![Kicker](/files/-LuiPOvGqfNH4HFfp_hV) 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. * **Start from note:** When this LED is on, the start tone will be the note selected in the Piano Roll * **End to nore:** When this LED is on, the end note will be the note selected in the Piano Roll * **Frequency slope:** Change the steepness of the frequency envelope. Larger values let you slide more. * **Click** adds a click/punch to the beginning of the kick sound * **Start** and **End Distortion:** Simple distortion envelope * **Gain:** Additional gain added to the output (makes it louder) * **Length:** Length of the volume envelope * **Envelope Slope:** Change the steepness of the volume envelope * **Noise:** Replaces part or the whole signal with white noise Kicker was originally meant for drum synthesis. It is best used in the Beat+Bassline-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. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
