Moog Music MF-107 FreqBox - Manual (Page 7)

7
Sync+FM
This setup is the same
as the previous, but adds
a dose of FM, which gives
the sound an extra bit of
growl, especially when
the frequency of the VCO
is swept with the Freq
control, or an expression
pedal plugged into the Freq
Input.
AutoSyncSweep
This setup uses the
dynamics of your playing to
modulate the frequency of
the VCO using the envelope
follower. Hard playing causes
the frequency to go up and you
get more sweep of the VCO
from the envelope follower.
This is a really good setup to
use with guitar, reminiscent
of an auto-wah type of effect.
The key to this setup is in
setting the Drive control (not
too much red showing on
the Level indicator) and the
Envelope Amount control.
Using an expression pedal to
control the frequency sounds
good with this setup.
