Hey hey,
I've just released m_cubicon:
http://juliencoder.de/sound/m_cubicon-0.5.zip
This oscillator holds a cube of waves which the user can browse in x, y and z
direction, optionally morphing or stepping between them. Each (default) cube
holds 27 waves. Eight cubes are already supplied, including the source
waveforms/spectra.

Furthermore wt_analysis.csd an experimental Csound utility to extract your own
waves/spectra from audiofiles is supplied. It worked for me, mostly.

Also included is a simple example of the oscillator.

At least one more cube is currently prepared and more more envisioned.
Suggestions for interesting harmonic source material or algorithmic harmonic
spectra is welcome.

Caveat: different interpolation/morphing of the harmonics is not yet tested,
although an example standard Csound score snippet is provided. With my Csound
6.12.2 the hvs3 opcode courses Csound to segfault the moment iconftab is not
0.

Feedback is always welcome, I hope you enjoy this opcode.

Best wishes,

Jeanette

Wow, this sound super cool and I look forward to trying it!

Thanks for your warm words.
For the waveform generation I mostly do use the supplied utility CSD.
For the moment I've gone for some simple synth waveforms (not yet part
of the package) and vocal samples. I suppose one might guess at least
one singer that I've gone for. :)

I have also used a few extremely simple c++ programs to generate some
algorithmic waveforms. The harmonic_cube1 for example, which is just the
base note and one harmonic with the amplitude 1/harmonic_number.

The extracted wavetables I process with simple shell scripts to remove
the ftsave header. All wavetables are then "normalised, i.e. add all
values and then do 1 / result.

>From the lists you see in the cube source directories, I create simple
shell scripts again to concatenate single waves into a full cube.

As for the primary choice of "sources" I went for vocal sounds in
particular since they have always strangely attracted me in wavetable
synths. Possibly a thing of synaesthesia and many such vowel-ish sounds
looking green to me. :)

I hope this answers your questions, without being too far beside the
point. :)

Best wishes and thanks again,

Jeanette

Correct, the first three original/new waves and the last one in each

Again correct.

...
The distance (spatial distribution) is equidistant. The particular waves
of each cube, I tired to organise due to similarity or difference. So
more or less arbitrary. The mapping from the snapshot table to the cube
though is fixed by the cube_pos ftable.

Yes. I had started my test-code by trying to move through all the waves
in the cube, meaning 9 times down the x-axis, three times down the
y-axis and once down the z-axis. I kept part of this on.
The wrapping and normalisation are done in these two steps, so I can
still decide whether to morph or fade from one wave to another or step
through the actual wave positions.

No problem, of course. I'm glad you enjoy it so much that you want to
delve and dig.
