• In conventional samplers the term “sample” normally refers to the wave data only. It is important to
remember that A5000/A4000 samples also include a number of sample parameters.
• Samples can be either mono or stereo. Stereo samples have independent wave data for the left
and right channels.
• The total number and size of samples that can be recorded or loaded into memory at a time will
depend on the amount of internal wave memory available.
• Sampling is carried out using the RECORD mode (page 150), while sample editing is carried out
in the EDIT mode (page 118).
Sample Banks
A “sample bank” is a group of samples which can be handled as a single sample. Multi-sampled
instruments, drum kits, etc., are collections of many samples that function together to create the
desired sound. By grouping all the related samples together as a sample bank, they can be copied,
saved, and otherwise managed all at once, making it unnecessary to go through the tedious process of
individually processing each sample.
• Multi-sampling is often used to achieve realistic reproduction of instruments that have a wide pitch
range. Small groups of notes or even single note are individually sampled, then the resultant sam-
ples are “mapped” to the playback key range, thus accurately reproducing the instrument’s natural
tonal variation across its entire range.
• Drum kits consist of individual samples of the various drum and percussion instruments required
— bass drum, snare, toms, cymbals, etc., — mapped to individual notes of the keyboard or other
controller.
• When multi-sampled data which was not created using the A5000/A4000 or A3000 is imported, an
appropriate sample bank will usually be automatically created. This may not occur, however, with
data imported from certain devices.
• Sample banks are created using the PLAY mode Sample Select function (PLAY – SAMPLE-
SmpSel, page 93).
