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. ## Buttons * **Absolute Value:** toggles taking the absolute value of the input waveform. * **Mute:** toggles muting of the output. --- # Agent Instructions This documentation is published with GitBook.
