This sets the level of the four frequencies.

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).
