Note: Controllers 7 and 10 are marked as (not available). Logic Pro uses these
controllers for volume and pan automation for the audio channel strips. Controller 11 is
marked as (Expression). It has a fixed connection to this functionality, but it can also be
used to control other modulation sources.
Sample Select
This modulation destination deserves a more thorough explanation. By default, Sample
Select is controlled by velocity through the default Velocity to Sample Select
modulation path. This means that the received note velocity value determines which of
the layered zones with different Velocity Range settings is heard.
However, you aren’t limited to only using velocity to choose what sample is played. By
assigning modulation sources other than velocity, for example the modulation wheel,
to the Sample Select modulation destination, you can determine which sample plays
using something other than velocity. You can even use multiple sources, such as both
velocity and the modulation wheel, using the modulation matrix.
When using multiple modulation sources (or any source other than velocity or key),
however, please keep in mind that these can 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. This means that
CPU usage will increase due to all velocity layers being active in memory, even if you
don’t hear them.
If you choose a continuous controller such as the modulation wheel to modulate the
Sample Select destination, you can step through the velocity layers during playback. In
this case, the crossfade (XFade) parameters are very important for creating smooth
transitions between velocity split points.
The Instrument Editor
You can use the Instrument Editor of the EXS24 mkII to create and edit sampler
instruments.
A sampler instrument consists of zones and groups:
 A zone is a location into which a single sample (or audio file, if you prefer this term)
can be loaded from hard disk or CD ROM.
 Zones can be assigned to groups, which offer several parameters for simultaneous
control over all assigned zones. You can define as many groups as desired. You can
edit the group parameters in Group view.
