FILTER
The filter has the biggest effect on the sound’s char-
acter or “timbre.” It affects the timbre by changing
the relative volume of certain frequencies in the
sound. Use it to give the impression that a sound
is “brighter” (more high frequencies) or “darker”
(more low frequencies). The “cutoff” knob sets the
frequency to be emphasized, and the other controls
“peak”, or intensity of the filter. If the “peak” is turned
up all the way, the filter turns into an oscillator!
