[PD] Analog/good-sounding oscillators in PD

[alexandre matheson]

hello,

Sounds like a very interesting project.

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?

see attached patch
