into the A6's audio path without filtering.
This direct signal flow from the sound generators, bypassing the filters provides
three distinct advantages when editing Programs. First, since sine waves have no
harmonics, filtering them has no effect on their tone--low
their amplitude. Making it possible to let the sine waves bypass the filters avoids this
situation.
Second, the sine waves available at this point in the mix are in addition to the
waveforms selected in
adding in unfiltered fundamental waveforms – with whatever waves are currently
being output by the VCOs results in a thicker bottom end that would otherwise be
impossible to achieve.
Third, there are also times when the output of the
unfiltered. This direct audio path permits mixing an unfiltered signal from the Ring
Modulator in with its filtered signal. The resulting blend of filtered and unfiltered
signals is a noticeably richer sound.
