[sc-users] buffer to ats file

[Josh Parmenter]

Hi Alo,

Sorry - I have a very busy day! But I will look into this this  
weekend. I actually have some students who want a similar thing, so I  
will think about the best way to do this.

One warning! atsa pegs the CPU. Doing these things on the fly may  
cause some poor SC performance.

What kind of transformations do you want to do on the fly? There may  
be some PV processes that you could use to mimic the ATS results. I  
have some nice ugens for extracting noise and partials. Not sure if it  
would work well... but it may be VERY efficient.

Best,

Josh
