For the two mid-range frequencies, you may also set the width of the EQ.
Larger values set a wider width whilst lower settings produce a narrow width.
WID = 99
WID = 00
With narrow WIDTH settings, you can accentuate certain frequencies more
tightly whereas with higher width settings, a wider frequency range is covered
by this EQ parameter. If you are familiar with synthesiser filters, this control is
similar to the resonance control. If you are familiar with parametric EQ devices,
this is the same as the ‘Q’ or ‘bell’ control found on outboard EQ devices or
some very expensive mixers’ EQ sections.
As mentioned, you may also modulate the two bandpass filters to create swept
‘auto wah’ effects. Normally, you would only modulate one of the bandpass
filters but you may independently modulate both for more extreme effects.
These effects are set along the bottom row of the page using the
(frequency modulation) and parameters. The parameter sets
the rate of modulation and the parameter sets the amounts of
sweep. The arrows indicate which parameter relates to which frequency band -
the controls to the left of the parameter affect MID1 and those to the
right of affect MID2.
Many effects are possible using the ‘autowah’ functions. Effects from ‘wah-
wah’ clavinet and guitar may be created by sweeping just one band (either will
do) and more extreme filter sweep effects can be created by sweeping both.
Low setting (i.e. tighter ‘bell’) accentuates the effect.
The phase shifter option in the MOD section can also be enhanced by
sweeping one (or both) of the bandpass frequencies with narrow width
settings at exactly the same rate as the phase shifter.
You could also experiment with setting the AUTOPAN selection in the MOD
section to the same rates so that EQ/filter sweeps pan in synchronisation with
each other.
Some of the effects presets utilise these effects - you may like to study them
for a better understanding of what is going on.
The BYPASS field allows you to switch the EQ section out of the effects chain.
You may also ‘flatten’ the EQ (i.e. set the parameters so that there is no EQ
applied) by setting the LOW and HIGH bands to 500Hz and 00dB and the two
MID sections’ level to (the mid bands’ frequencies have no effect when
is set).
