yes
i downloaded orion, simsynth and reaktor.
i haven't tried to get buzz working yet, because i've been playing with these three.
with orion i came pretty close to that horn sound in mauro picotto's 'iguana'. i also ended up with several police sirens (i thinks that's what they're called in English).
i haven't done literally anything with simsynth yet, but i think it might be able to do lots of things for me.
reaktor, i think is the best of all of these, but i still haven't figured out how to use it. i even can't get any sound out of it.
basically my knowledge of software synthesis is zero. the only things i remotely know about are the attack, decay, sustain, and release knobs. everything else i just turn almost randomly. at one point a knob has a certain effect on the sound and the next minute it has a different effect. i guess i should read the manuals.
anyway, i can't say that i can create anything that i want to create with these programs.
