Basic Operations
A number of the tones that are available with this keyboard
have been recorded and processed using a technique called
digital sampling. To ensure a high level of tonal quality,
samples are taken in the low, mid, and high ranges and then
combined to provide you with sounds that are amazingly
close to the originals. You may notice very slight differences
in volume or sound quality for some tones when you play
them at different positions on the keyboard. This is an
unavoidable result of multiple sampling, and it is not a sign
of malfunction.
This keyboard has only a single DSP sound source. Because of
this, selecting tones for which DSP is enabled for multiple
parts when layering or splitting tones (page E-66, 67) can
cause conflicts. To avoid conflicts, DSP is allocated to the last
DSP enabled tone, and DSP is disabled (DSP line OFF) for all
other parts.
DSP line is a parameter that controls whether or not the
currently selected DSP effect is applied to a part.* Each tone
has a DSP line parameter. Selecting a tone for a part applies
the tone’s DSP line parameter setting to all parts.
* The DSP line parameter is turned on (DSP effect is
applied) for the 300 Advanced Tones numbered 000
through 299, and turned off (DSP effect not applied) for
the 200 preset tones from 300 to 499. For information
about other tones, see “Tone Types” on page E-19.
Pressing this button changes the setup of the keyboard to
