This plugin allows you to take the waveform of a signal and use it as a controller. The output can be found in the controller rack labeled as "Controller #" with # being the number of the controller.

## Knobs

* **BASE:** adjusts the starting point of the resulting controller's signals.
* **AMNT:** adjusts the amount in which the amplitude of the input signal affects the controller's output (Note that this can be negative).
* **MULT:** adjusts the number that **AMNT** is multiplied by.
* **ATCK:** adjusts the time taken for the signal to reach its peak
* **DCAY:** adjusts the time taken for the signal to return to its baseline.
* **TRSH:** adjusts the amplitude threshold of the controller. (In other words, how "loud" the signal needs to be to trigger the controller.&#x20;

## Buttons

* **Absolute Value:** toggles taking the absolute value of the input waveform.
* **Mute:** toggles muting of the output.
