This demo video shows the 30 raw original wavetables from the PPG wave 2.2 synthesizer from the year 1982.

Wavescanning with envelope 1, VCF is full open, no resonance.
Each wavetable has 64 waveforms.

PPG wave wavetables:
00. Harmonics 1-8 very strong, simulation of a
resonant filter, wave number 00 is a sine.

01. Similar to wavetable 00, but with additional
higher harmonics, dual VCF simulation

02. Similar to two previous wavetables, but
also good for vibes, bells, tubular bells.

03. Sine-to-rectangular sweep, low-resonance
VCF simulation, like for clarinette and flute.

04. Waves 00-47 feature very high harmonics
in progressively greater amplitudes.
Waves 48-59 continue to add high
harmonics but at a faster rate. Also useful
for delay effects and church bells.

05. Very high harmonics are emphasized,
effects similar to wavetable 15, but more
mixture like.

06. Sine-to-ramp sweep, low-resonance-VCF
effects, also good for woodwinds.

07. VCF sweep without resonance, also useful
for woodwind sounds.

08. Highpass VCF simulation, no resonance.
Wave 00 has no fundamental. Wave 25
has fundamental at maximum amplitude.
Useful for dark percussive strings, bass
with click-like attack.

09. Formants are strong middle-range
harmonics, useful for ring-modulation and
vocal sounds.

10. Similar to wavetable 09.

11. Low formants. Wave 00 is dark, 32 is
bright, 59 is dark.

12. High formants that sweep.

13. Very strong high-order harmonics, the
fundamental is weak. Useful for bright
percussive stringed keyboard instrument
sounds like clavichord. When swept, you
get an amplitude modulation effect. Wave
00 is maximum amplitude, 24 is minimum
amplitude, 59 is maximum. Use great
detuning, upper waves and dissonant low
chords for noise effects.

14. Several organ registers.

15. Harmonics 2 + 3 to sawtooth sweep.
Useful for harmonium or accordion.

16. Wild amplitude modulation effects when
swept. Some peaks and dips in amplitude.

17. Wave 00 features the fundamental and
second harmonic. Wave 14 is the
fundamental alone. Wave 40 has high
harmonics. Wave 59 is the fundamental.

18. When swept produces high-low-high
harmonic sweep effect.

19. Waves 00-32 are stationary waveforms
with string upper harmonics and a few
lower harmonics. Wave 59 has no
fundamental.

20. Fast discrete changes of low and high
harmonics for sample and hold effects.
Wave 00 is a sine wave.

21. Sine wave to high frequency formants.

22. This wavetable is particularly suited for
echoing effects. Waveforms vary from
original attack plus one delay, to two
coloured delays. Wave 00 is a sine wave.

23. Strong high harmonics.

24. Stationary organs. If swept produces
ascending high harmonic sweeps.

25. Waves 59 to 49 go from bright to sine
wave. 48 to 33 have a coloured delay. 33
to 18 are sine waves. 17 to 00 have a
coloured delay echo.

26. Variations on sawtooth waves in strong,
bright formants. Good for brass sounds.

27. Formant sweeps. When keyboard is used
to control the waves, for vocals and choirs.

28. Phasing sawtooth waves. Useful for
ensemble string sounds.

29. Square to rectangular to narrow pulse
waves. Sweeps produce pulse width
modulation effects.

30. Used on older wave 2.2's to hold sampled
