.Completing Your Multisounds
JJ Explanation of multisound parameters.
■ In the final stage of multisound development you
must assign your sounds to the keyboard and set the^
multisound parameters. There are six mu It ¡sound
parameters.
■ I) The original key/top key parameter is used to
assign sounds to the keyboard.
When using sampled sounds, you normally take
several samples of the same instrument playing
various different pitched notes. For example, you
might take a sample in each octave. With the O RG /
TOP parameter you assign these sampled sounds to
the DSS-1 keyboard. Ordinarily, the O RG or "original
key" value is set to the key that has the same pitch as
the sampled sound. The TOP or "top key" value is
set to a key that is within the upper limit for “reading
out” the data from memory (more about that later).
The lower limit is taken care of automatically; it is the
key that is a semitone above the TO P key value of the
next sound down the keyboard. In the case of the
lowest assigned sound, the lower limit is the limit of
the DSS-1 rs assignment capability (which will be the
lowest key in the "virtual keyboard" in the diagram
below).
The DSS-1 has a virtual (or imaginary) keyboard that
covers the range from C #-1 to G9. When you assign
sounds, you set their ORG and TOP values to keys
within this virtual keyboard range.
(The D SS-1 's 61-key physical keyboard produces the
sounds in the virtual keyboard according to the set
tings of program parameters such as the oscillator
octave and interval. Refer to the descriptions of the
F11 O S C O CT and F15 O SC 2 D ET U N E & INTERVAL
functions. You coufd say that the physical keyboard is
a sliding “window" on the virtual keyboard.)

Up to 16 sounds can be assigned to the keyboard. In
other words, a single multisound can contain a max
imum of 16 sounds.
