Important
• On most conventional samplers, a "sample" consists of waveform data only. The A3000
is a more sophisticated device that associates a variety of editable parameters with
each waveform.
• An A3000 sample may be either stereo or monaural. A stereo sample contains two
waveform patterns — one for the right channel, and another for the left.
• The amount of available memory determines the length and number of samples that
can be used at any one time.
• The A3000 offers a special object type, referred to as a sample bank. The sample bank
consists of a group of samples, but can be handled in the same way as a single sample.
Details are provided later in this chapter.
A program is a playable collection of samples and other data. The program is the object
that you use when you want to play sounds from the A3000.
The A3000 provides 128 programs, each identified by its own program number. Pro-
gram numbers run from 001 to 128.
Note that all 128 programs are always resident in memory, even though many of these
programs may be empty of data. In fact, when you first switch on the A3000 all 128
programs will be completely empty and essentially useless. Even an empty program is
considered to exist, however, since it is always possible for you, or for an external MIDI
device, to select it.
Program Data
Programs consist of the following data types.
Program parameters
ToPgm switches
Easy-edit parameters
The following diagram again illustrates the relation between samples, programs, and
data types.
General playback settings: effect selection, sound output level,
and others.
The sample select/deselect switches described above. These
switches determine which samples the program uses.(Note that
ToPgm stands for to program.)
Edit settings that temporarily adjust or override the sample pa-
rameters of the selected samples (the samples selected by the
program's ToPgm switches). Note that the easy-edit parameters
do not overwrite the sample parameters, but simply "overrule"
them during the time that the program remains in use.
