Chapter 19 EXSP24 123
If planning to do so, however, please keep in mind the fact that all sources (except
Velocity and Key) cause all velocity layers to run simultaneously—using up as many
voices as there are layered Zones. This also happens in cases where the Zones are not
audible at the current control level.
If a continuous controller (such as the modulation wheel) is chosen, you can step
through the velocity layers during playback. This is where the XFade parameter
becomes important, as it allows smooth transitions between velocity split points.
Keep in mind that you can also combine velocity and modulation wheel control by
using the Modulation Matrix (see “Modulation Matrix” on page 129).
Pitch Parameters
Tune
Offsets the pitch of the sample(s) in semitones by up to ±2 octaves. The middle
position of the knob (which can be set by clicking the small 0 button) leaves the pitch
unaltered.
Transpose
This parameter allows you to transpose the EXSP24. In contrast to the Coarse Tune
parameter, Transpose not only affects the pitch, but also moves the Zones in
accordance with the Transpose setting.
Random
This rotary knob controls the amount of random detuning which will apply to every
played note. Random ranges from 0 to ±50 cents.
You can use Random (detune) to simulate the tuning drift of analog synthesizers. This
parameter can also be effective in emulating a natural feel for some stringed
instruments.
Fine
Allows the EXSP24 to be fine-tuned.
