Q: How to create files to import user wavetables?

A: The main problems with user wavetables are the material that is imported.

Besides the 64 wave cycles of 256 sample words (=16384 samples), the waveshapes should not be changing to drastically from wave to wave. A rather smooth transition from one to another wave sounds better. On the original PPG wavetables, only every second wave is actually content (on most wavetables even only a very few). All others are interpolated. And these wavetables are the classic about 30 first ones of the microWave. So do not expect smooth wavetable flows if the material is changing too much. So do not use wavetables with drastic changes from one to another wave if you expect a somewhat classic wavetable like character. The famous PPG wavetables are famous, because most of them work good for long range wave position modulations. They are not all like the upperwavetable, which you will not like to scan through that much for normal sounds.

And to avoid clicks (which will happen in the original microWave mode anyway), be sure, each wave cycle is balanced and not producing a DC offset. And that the waves start after a zero crossing and ends just before one.
Due to these needs, not harmonic content or content with not perfect tuned harmonics will not work as intended. So do not detune harmonics if you generate wavetable data. And be very sure, that the pitch is the steady, otherwise the wave cycles will not be exact 256 samples long.
I made experiments with reducing the 256 to effective 64 samples (4 identical samples x 64 = 256), and this gave a extra derez like character sounding even more PPG alike.

And avoid doing to much wavetable position modulation, as the classic mode (I mainly use this one) will cause clicks, as the waves are switched with no waiting for zero crossings. So this is by design on the Waldorf M to get a true classic microWave mode.

And please take your manual copy and write "unsigned" where "signed" is written in the way to short wavetable import section.    ^
