WORKING WITH THE FILTER

The low pass filter makes it possible to remove certain components of
the sound. A low pass filter removes the high frequency components
or put another way, it "lets the lows pass". In preparation for this
experiment choose a fairly "normal" preset (like an organ or piano).
Go to the Secondary Instrument screen and set it to "None", then set
the Primary Instrument to one which is rich in harmonics, such as the
Violin Trio. (Since the filter works by removing certain frequencies, we
want to make sure that we have a lot of frequencies to start with.). Set
the parameters as listed in the chart
below in order to "clean the slate" for
your filter investigation.
Go to the primary filter cutoff and Q
screen shown below and position the
cursor below the Fc value.
