It is my understanding that analog synthesizers generate the basic
waveforms with additive synthesis. I'm wondering if using [tabosc4~]
and sinesum be a step in the right direction?
To fight foldover at half the sample rate this will only work for a certain range. For example if you want to play any non-sine waveform at almost half the sample rate, you will only be able to play a sine-waveform at that frequency without any partial above that folding over. Such foldover will also happen when you play a sinesum through tabosc4~.
Miller's book describes some ways around this problem, which I sometimes use as well (attached is a little GOP abstraction ripped straight from his examples).
Besides foldover, which can be fought, there also is another area of getting "good" sounding analogish oscillators: Analog gear tends to have certain distortions an irregularites, that people tend to like and to associate with that "warm" analog feeling. I guess, Reaktor may introduce some of this stuff as well. There is a LADSPA plugin, forgot its name, by Steve Harris which has a "warmth" control to introduce such distortions, but I think, these are hard to model and would need a lot of fiddling. Anyways static waveforms always tend to sound a bit digital, so finding ways to make the sounds dynamic often is useful.
