Wavetable playback of a normal sample
Very interesting sounds can be obtained if a normal
sample is played back in wavetable mode - especially
if human voice is recorded.
During normal sample playback the sample length
depends upon pitch and the so-called Mickey Mouse
effect occurs.
If the wavetable mode is used the sample length
depends only upon the slope of the controlling voltage
(e.g. sawtooth) but not upon the pitch. This is adjusted
independently with the tune control and pitch CV.
Suggestions for sound experiments:
• If the slope of the voltage controlling the wavetable
is running backwards (e.g. a falling sawtooth) sam-
pled words seem to be spoken backwards (sort of).
• By selective scanning of a spoken sample one may
obtain voice or vowel loops.
• Using a random or S&H voltage for controlling the
wavetables leads to the basics of what is often
referred to as granular synthesis.
For the above suggestions it is important that the
period of the sampled sound fits almost exactly into the
space allotted to each wavetable (256 Bytes). If the
result is not satisfactory another record sampling fre-
quency should be used until the desired sound is
obtained.
