• Each Group offers separate ADSR parameters for offsetting the ADSR volume
envelope settings made in the Plug-in window: The Attack, Decay, and Release time
parameters can be adjusted by ±9999 ms, the Sustain level by ±50%.
• Similarly, the Cutoff and Resonance settings of the Plug-in window can be offset by
±50% for each Group.
It is possible to play all Zones without defining and assigning a Group—in such cases,
the parameters defined in the Plug-in window work in an absolute (identical) manner
for all Zones.
Detailed descriptions of all Zone and Group parameters can be found in “Zone
Parameters” on page 564 and “Group Parameters” on page 566.
File Organization
File Types and File Organization
The EXS24 uses the following file types and hierarchical structures:
Audio File
A single sample on your hard disk. The EXS24 is compatible with all audio file formats
supported by Logic. Audio files are handled in the EXS24 Instrument Editor, where they
can be edited and organized into Sampler Instruments.
Sampler Instrument
A Sampler Instrument points to one or more audio files, and organizes them as multi
samples or drum maps, respectively. Within the Sampler Instrument you may assign
different samples to different key and velocity ranges, set loop points, and adjust other
playback parameters. You can also work with Zones and Groups (see the “Multiple
Zones and Groups” section, from page 525 onwards), which always belong to a
Sampler Instrument, and are not stored or loaded separately.
Note: Audio files are not contained in a Sampler Instrument. The Sampler Instrument
simply stores information about an audio file’s name, its parameter settings, and its
location on the hard disk. When you delete or rename an audio file, the Sampler
Instrument that makes use of it will be unable to find it, so take care when handling
audio files.
A Sampler Instrument is the file type that is loaded into the EXS24 for playing. When
you select a Sampler Instrument in the EXS24’s pull-down menu, the associated audio
files are automatically located on the hard disk, and are subsequently loaded into your
computer’s RAM.
In order to be visible within the EXS24’s Sampler Instrument pull-down menu,
Instruments must be stored in the Sampler Instruments sub-folder of the main Logic
program folder.
