The ROM waves in the Waldorf Microwave synthesizers are a great start for building your own wavetables. Unfortunately there is only very little documentation about these waves :
the only provided documentation is a Postscript file on the (Waldorf ftp site). To make the information a bit more accessible I have transformed the data from this file
in a more graphical format using the Reporting tool WebFocus from Information Builders ,who are very friendly to support my bankaccount every month...
The reports are in fact a Fourieranalysis showing the first 32 harmonics of a wave. The amplitude of the harmonic is represented by the size of a red circle (guess why a red circle !!). For easier interpretation all spectra are normalised to the strongest harmonic : in plain language : the strongest harmonic of all spectra have the same size circle. This harmonic is also marked with a silver background. Why this technique ? In this way it is very easy to compare the relative amplitude of the harmonics in a wave. The side effect is though that it is hard to compare absolute values of amplitudes between waves, but I am convinced that this representation is the easiest way for choosing waves for wavetables (and that is was the goal). Though only 32 harmonics are shown the Microwave II is capable to generate harmonics up to number 64. I didn't add these higher harmonics : the most waves have very few of them , and adding them would make the reports just too big to fit on your screen.
To make printing a bit easier the output is split in groups of 50 waves.
