STEP-BY-STEP
• Filter Filosophy
The Instrument and the Filter work together to determine the harmonic
content of the final sound. You can think of the instrument like clay
which is being squeezed through a die, the filter. The filter tries to
impress its structure on the harmonics of the instrument.

Of course, the filter cannot amplify or attenuate frequencies which do
not exist in the original instrument. The Filter Frequency Tracking
control can be used to “tune in” the filter to match the instrument.
The Filter can only act on frequencies that are present in the Instrument. Use the Filter
Frequency Tracking control to “fine tune” the filter to the instrument. No sound
would be output from the example above because the filter's frequency response and
the harmonic spectrum of the instrument do not coincide.
