Programs
When you play a sound on your sampler, you are actually playing a "program" to which the necessary
samples and/or sample banks are assigned. There are always 128 programs in memory — even when
the power is first turned on the sampler contains 128 "initialized" programs (program numbers 001 —
128).
Program Data
The data included in programs can be broadly divided into three types:
1. Sample Select
This parameter specifies which samples and/or sample banks residing in the sampler's memory
are to be used by the program.
• In programs, multiple samples can be "layered" and played simultaneously, played on separate keys, in speci-
fied velocity ranges, and more.
• Samples and sample banks can only be played via MIDI control when they are assigned to a program.
• Sample and sample bank assignment is carried out by using the Sample Select parameter in the PLAY mode
(PLAY – SAMPLE – SmpSel, page 93).
2. Easy Edit
This type of data allows the sample parameters to be temporarily adjusted as necessary (these
adjustments only apply to the program to which the samples/sample banks are assigned).
• Easy Edit can be applied individually to all samples and sample banks assigned to the program.
• Easy Edit allows samples to be adjusted only for the corresponding program, without actually changing the
sample's parameters. A single sample can therefore be used in multiple programs with different Easy Edit
adjustments for each program.
• Easy Edit is accessible via the Play Mode Easy Edit function (page 96).
3. Program Parameters
This data specifies the program's volume (loudness), how it will be affected by MIDI controllers,
and other important parameters that affect playback. This also includes individual effect settings
for each program.
• The program parameters are accessed via the PLAY mode Program (page 89), Effect (page 102), Setup (page
107), and Control (page 110) displays.
