MOTM

My point exactly, the use of discrete operators is the way to go, nice 
sounding such too. What I'm talking about is the analysis stage. How to 
extract those overtones and their envelopes, with some sort of averaging 
function that makes musical sense. A more simplified, pure way. Like you 
say, not necessarily to reproduce a natural sound, but a sound that 
sounds good.
Even if you play back an FFT analysis through discrete oscillators , you 
still get flutter etc.

FFT is probably the way to go in the end, but with a couple of smart 
timbral averaging additions.  Then you also need a way to get smooth 
envelope curves with only a few points (few compared to unlimited..). 
Smooth but without loosing information in the attack.

I've played with the Axcel many times, and I always come to the same 
result, nothing....
It's got the coolest user interface on the planet, but the worst 
sounding engine ever. Great show piece but nothing more.
