AW: additive

[Haible Juergen]

If you want to make analogue additive synthesis (rather)
simple, you might try this:

Start with a triangle VCO, and derive as many triangle
"harmonics" as possible with waveshaping.
Then use 3080's or similar OTAs for creating sine waves
from the triangles. Use the control input of the same OTAs
to get the VCA function. Connect all OTA outputs directly
together.
Try simple Envelopes. A 1ms-attack / variable decay
might be enough for higher harmonics, if you have a master
VCA at the end with a standard envelope.

Just an idea - haven't tried it.
