■ The DSS-1 stores its waveforms as digital data in
memory. When a sound is to be used, the data is
read from this “wave memory” and converted into an
analog signal which is output by the oscillator. Actual
ly, data for several different waveforms is used, since
the waveform reproduced depends on the area of the
keyboard being played. This gives us the idea of
“multisound.M

The area of the keyboard played
determines which waveform Is
used.
The supplied demonstration disk lets you hear how the
sound changes according to waveform assignments
across the keyboard.
