I think the second one makes the first sound better. Probably because I
much prefer the first few seconds with the new timbre. And it sounds less
like a real gamelan.

New fifths are smoother, yes. Also, they alternate rough/smooth in that
example. Is it an illusion, or are they tuned differently?

Probably it would have sounded like a gamelan whatever you called it. But
the new timbres make it sound more individual.

I think the first two are like that. Perhaps it skewed my perception of
the rest.

It might be something to do with the resolution of the tuning tables. Or
even aliasing.

No, not me. I have Kyma. It does additive synthesis, but it's quite
processor hungry so I usually use other algorithms. I have set up some
phi timbres and posted some examples somewhere. And didn't I duplicate
one of your timbres once?

Kyma, yes. You can even set them as Smalltalk expressions.

FM's great if you go with the flow, and don't worry if your predictions
turn out wrong. If you want additive timbres, CSound can do it. Maybe
not in real time, but you should be able to generate files for use with a
soft sampler.

I thought it made great Gamelan, personally. Congratulations are due!
