578 Chapter 29 Ultrabeat
Note: Option-clicking the Hz parameter returns its value to a neutral position. This is
200 Hz for the first band and 2000 Hz for the second. The selection of these default
frequencies was made in accordance with the different shelving characteristics of each
frequency band. Band 1 is designed to filter low frequencies and band 2, high
frequencies.
The Q factor is regulated by click-dragging vertically on the Q parameter field. The
effect of Q on the sound is heavily dependent on the selected EQ type:
 With shelving filters, as the Q value goes up, the area around the threshold frequency
becomes more pronounced.
 With the peak EQ, Q determines the width of the frequency band selection: low Q
values select a broad band while high Q values select a very narrow band to be
boosted or reduced with the Gain control.
Editing the EQ Bands Graphically
The EQ bands each have their own display which shows changes on a frequency
response curve. The display provides immediate access to the Gain, Hz, and Q
parameters. Just grab the graphical frequency response curve with the mouse, and
alter it by moving the mouse vertically or horizontally! Horizontal moves change the EQ
frequency, and vertical moves influence the Gain. At the peak (maximum point) of the
EQ, a handle can be dragged vertically to change the Q factor.
Pan Modulation and Stereo Spread
The EQ’s output signal is passed along to the Pan Modulation and Stereo Spread
section. In the Pan Modulation and Stereo Spread section, the placement of the sound
in the stereo field (set in the Assignment section’s mixer) can be modulated (Pan
Modulation mode), or the stereo basis of the sound can be broadened (Stereo Spread
mode). Activate the desired mode by clicking on the appropriate button (Pan Mod or
Spread).
If neither mode is activated, the signal passes through unaffected.
