It is generally not possible to use a single sample to reproduce an instrument sound
accurately over a large range of keys. Instead, the way to get faithful reproduction is to
record several samples from the original instrument, each at a different pitch, and then
assign each of these samples to a corresponding area of the keyboard. This approach is
referred to as multisampling.
Once you have produced these samples, you will want to keep them together and treat
them as a group. The A3000 therefore lets you handle the entire group of samples as a
single unit, called a sample bank.
As an example, assume that you want to use three samples to record a piano: Sample A
to generate sounds from C1 to B2, Sample B for the range C3 to B4, and Sample C for
the range C5 to B6. If you do this without using a sample bank, the setup will look like
this.

The difficulty with this approach is that each time you wish to use the piano sound in a
different program, you must remember to set the program's ToPgm switches ON for all
three of these samples. And when you need to save the samples to disk or reload them,
you must always remember to save or load all three of them together.
By setting up a sample bank, however, you can avoid these problems. The sample bank
lets you treat all three samples as a single unit. In practice, you can treat them as if they
were a single sample. The following illustration shows the idea.
