This is the description of the PPG Wave 2.2 wavetables as used in the Microwave II/XT. (Plus Wavetable 64).
\begin{itemize}
\item 001 Resonant: Harmonics 1-8 very strong, simulation of a resonant filter,wave number 00 is a sine wave.
\item 002 Resonant 2: Similar to wavetable 00, but with additional higher harmonics, dual VCF simulation.
\item 003 MalletSyn: Similar to two previous wavetables, but also good for vibes, bells, tubular bells, and so on.
\item 004 Sqr-Sweep: Sine-to-rectangular sweep, low-resonance VCF simulation, clarinette and flute sounds
\item 005 Bellish: 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.
\item 006 Pul-Sweep: Very high harmonics are emphasized, effects similar to wavetable 15, but more mixture-like.
\item 007 Saw-Sweep: Sine-to-ramp sweep, low-resonance-VCF effects, also good for woodwinds.
\item 008 MellowSaw: VCF sweep without resonance, also useful for woodwind sounds.
\item 009 Feedback: 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.
\item 010 Add Harm: Formants are strong middle-range harmonics, useful for ring-modulation and vocal sounds
\item 011 Reso 3 HP: Similar to wavetable 09.
\item 012 Wind Syn: Low formants. Wave 00 is dark, 32 is bright, 59 is dark.
\item 013 High Harm: High formants that sweep.
\item 014 Clipper: 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.
\item 015 Organ Syn: Several organ registers. Sine, Hammond, Lowery, Church organs.
\item 016 SquareSaw: Harmonics 2 + 3 to sawtooth sweep. Useful for harmonium, accordian, harmonica sounds.
\item 017 Formant 1: Wild amplitude modulation effects when swept. Several peaks and dips in amplitude.
\item 018 Polated: 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.
\item 019 Transient: When swept produces high-low-high harmonic sweep effect.
\item 020 ElectricP: Waves 00-32 are stationary waveforms with string upper harmonics and a few lower harmonics. Wave 59 has no fundamental.
\item 021 Robotic: Fast discrete changes of low and high harmonics for sample and hold effects. Wave 00 is a sine wave.
\item 022 StrongHrm: Sine wave to high frequency formants.
\item 023 PercOrgan: 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.
\item 024 ClipSweep: Strong high harmonics.
\item 025 ResoHarms: Stationary organs. If swept produces ascending high harmonic sweeps.
\item 026 2 Echoes: 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.
\item 027 Formant 2: Variations on sawtooth waves is strong, bright formants. Good for brass sounds.
\item 028 FmntVocal: Formant sweeps. When keyboard is used to control the waves vocal and choir sounds can be produced.
\item 029 MicroSync: Phasing sawtooth waves. Useful for ensemble string sounds.
\item 030 Micro PWM: Square to rectangular to narrow pulse waves. Sweeps produce pulse-width modulation effects.
\item 064 Chorus 2: 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."
\end{itemize}
What about the other ones?
More details: A Visual reference of the XT's preset wavetables.With this type of information is morevaluable when programming the MW2/XT(k). \notes{Not all tables are covered.}
Here are the Waldorf Microwave2/XT wavetable reference charts I've made so far. When I'm finished, there will be one chart for each preset wavetable in the MW2/XT for a total of 64. I plan to complete these as soon as I can but unfortunately I have a day job and a life outside of synthesizers (hard to believe I know).
If you haven't been there already, don't forget to visit the MWXT Main Page.
This type of information is really useful when programming. Its also a good reference on how to construct musically useful wavetables. 0-60 on the left side of each chart are the "startwave" positions (BTW - 61, 62 \& 63 are the basic "synth" waves - so these are left off) and the red numbers show the Microwave's ROM waveform numbers and their positions within the wavetable. Empty spots are interpolated waves! To the right are graphical depictions of the applicable waves and their associated FFT spectrum.
\todo{Add all these one per page as the pictures contain the text aswell!}
