This is the description of the PPG Wave 2.2 wavetables as used in the Microwave II/XT.

(Plus Wavetable 64).

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

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

Similar to two previous wavetables, but also good for vibes, bells, tubular bells, and so on.

Sine-to-rectangular sweep, low-resonance VCF simulation, clarinette and flute sounds.

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

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

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

VCF sweep without resonance, also useful for woodwind sounds.

Highpass VCF simulation without resonance. Wave 00 has little or no fundamental. Wave 25 has fundamental at maximum amplitude. Useful for dark percussive strings, bass with click-like attack.

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

Similar to wavetable 09.

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

High formants that sweep.

Very strong high-order harmonics, the fundamental is weak. Useful for bright percussive stringed keyboard instrument sounds like clavichord, harpsichord, and so on. 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.

Several organ registers. Sine, Hammond, Lowery, Church organs.

Harmonics 2 + 3 to sawtooth sweep. Useful for harmonium, accordian, harmonica sounds.


Wild amplitude modulation effects when swept. Several peaks and dips in amplitude.

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

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

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

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

Sine wave to high frequency formants.

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

Strong high harmonics.

Stationary organs. If swept produces ascending high harmonic sweeps.

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

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

Formant sweeps. When keyboard is used to control the waves vocal and choir sounds can be produced.

Phasing sawtooth waves. Useful for ensemble string sounds.

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

Description by Wolfram Franke (Dec. 1999):

"The wavetable is an analysis of a
male choir sample I did 5 years ago for the Wave. The original choir pitch
was F 1 and the Wave transformed it so that it generates an equal formant
spectrum through the whole keyboard range."
