There are numerous audiofiles around containing one single cycle wave to
be used with multiple wavetable synthesizers, both in hard and software.
I can only assume that these are matched to the number of samples they
contain. Some of them CERTAINLY proclaimed this fact, AFAIK. I don't
have a wavetable synth that would directly accept waves, but I have
access to synthesizers with additive capabilities, including Yoshimi. So
converting such "prepared" waveforms to additive spectra is quite
useful.

I already have a more general solution in Csound, which works with a
generic FFT, to be used with real world samples. But it takes some time
and contains its own hazards. :) So a dedicated solution seemed
preferrable.

Many thanks for your clear description and the useful caveats so far!

Best wishes,

Jeanette
