counteract this, but that's the nature of the non-linear functions. In extreme cases, you can
lower the HiKey of the layer to disable the high end completely.
High Frequency Stimulator (HIFREQ STIMULATOR)
The overall effect of this three-stage function is to boost the high frequency partials of the
signal, and depending on the settings of the control inputs, it can add high-frequency partials
to the signal as well. It's useful for building sounds that cut through the mix, and have a bright
crisp nature.
There's more to the High Frequency Stimulator than meets the eye. It works like this: the signal
is run through a high-pass filter, then through a distortion function, then through a second
high-pass filter. Finally, it's mixed with the original signal after passing through the final AMP
stage of the algorithm. The three control input pages let you adjust the cutoff frequency of the
first high-pass filter (F1 FRQ), the amount (drive) of the distortion function (F2 DRV), and the
mix (relative amplitude) of the stimulated signal with the original (F3 AMP).
