Wavetables



I sampled the wavetables of the WAVE and did a FFT to show the harmonic content. Wavetables 01 to 30 are the original ones of the PPG waves. They were numbered 00 to 29 on the PPGs. PPG wavetable #30 were a special one called "Upper Wavetable". #31 Was some kind of a sample wavetable (including a sax and a piano). These wavetable are not implemented on the Waldorf synths (except for the PPG wave 2.V VST Plug-In). The other Waldorf wavetable synths as microwave, microwave2, XT and XTK would have shown the same results.
No filtering was used. The amplitude is not shown linear. The frequency axis (x) is linear scaled as on most FFT charts and starts at 88 Hz and goes up to a little bit more than 22 kHz.

On the left are the deeper frequencies.
In the front are the lower wave numbers.
The area is getting higher and darker on stronger frequency bands.
