The Effects
31
DET - Selects the type of detector to use, RMS or Peak.
MUTE - Mutes the output of the band. You can use the mute controls to audition one or more bands.
Filter
The Filter module is a simple programmable filter designed for general tone shaping. It allows a
variety of different filters along with real-time control of the filter parameters. You can use the Filter
module for quick, static tone shaping or for elaborate, dynamic tone manipulation.
It can be used as a straight gain block by setting the filter type to NULL. Another possibility is to
use it as a treble booster (with more programmability than the one in the Drive module).
In the 60's guitarists began experimenting with booster pedals to increase the signal level into their
amplifiers. This increased the amount of distortion their amps would produce. The more popular
booster pedals had extra treble boost in addition to overall boost. This technique was essential to
Brian May's tone on the early Queen recordings where a treble booster into a Vox AC-30 gave that
unmistakable sound.
To use the Filter/Boost module as a treble booster set the
TYPE to either HIGHPASS or
BANDPASS. Experiment with the Q and FREQ controls to achieved the desired effect. Increase the
level to increase the overall signal level out of the block.
The
FREQ, Q, GAIN, LEVEL and BAL parameters are all controllable. To attach a modifier to these
parameters select the parameter and press
ENTER
. This brings up the
MODIFIER
menu. When any
of these parameters are attached to a modifier an asterisk (*) appears after the name indicating such.
The Filter block also contains individual left and right pan controls. These controls allow you to
adjust the placement of the left and right output signals in the stereo field. You can use these
controls to turn a stereo signal into two mono outputs (set both to 0.0), or reduce the stereo
separation or as general stereo manipulation tools.
Parameters
TYPE -
Sets the type of filter. All the standard filter types are available. A NULL type has a flat
frequency response characteristic and can be used if you want to use the block as a simple gain
element.
FREQ -
Sets the center frequency of the filter.
ROFFS -
Sets the right channel frequency offset as a multiple of the left channel. A setting of 0.5,
for example, would set the right channel frequency to half the left.
Q-
Sets the ‘Q’ of the filter. Higher values give sharper responses.
GAIN -
Sets the gain at the center frequency for the bandpass, notch, low-shelf and high-shelf types.
This control has no effect with the other types.
LEVEL -
Sets the output volume level of the block.
