Chapter 19 EXSP24 125
Please note that the upper half of the Pitcher slider can be set above the center
position, and the lower half below the center position. When the Pitcher sliders are set
in this fashion, lower velocity values cause the pitch to rise from the lower setting back
to the original note pitch, while higher values cause it to fall from the higher setting
back to the original value. In other words: the polarity of the pitch envelope can be
changed according to velocity values.
When both halves of the pitcher slider are set below or above the centered position,
either a low or high velocity will slide up/down to the original pitch. Dependent on the
position of the upper/lower halves of the slider in relation to the center position, the
time required for the slide up/down to the original note pitch can be adjusted
independently for both soft/hard velocities.
Filter Parameters
Filter On/Off Switch
This button switches the filter section on or off. Please note that the knobs and buttons
in the silver panel area and the Filter Envelope are only active when the filter is turned
on. When the filter section is turned off, the EXSP24 is far less CPU-intensive.
Lowpass (LP)
The Lowpass Filter offers four different settings for its cutoff steepness: 24 dB (4 pole),
18 dB (3 pole), 12 dB (2 pole), and 6 dB (1 pole). The 24 dB setting can be used for
drastic sweep effects, such as cutting off all but a few notes, or for the creation of ultra-
deep bass sounds with just the necessary amount of overtones. The slope setting of
6 dB per octave is very useful in cases where you want a slightly “warmer” sound,
without drastic filter effects—to smooth “overly bright” samples, for example. The two
remaining values may be used for any purposes.
Fat (Fatness)
The Fatness mode is separate from the slope setting, and can be used with all available
slope values. Fatness preserves the bass frequency response, even when high
Resonance settings are used. Please note that this only applies to Lowpass filters.
Fatness is non-functional when used in conjunction with the High or Bandpass filters.
