I understand.  This is obviously still a very early stage in the 
product, and I certainly appreciate the emphasis on quality.  I was 
merely a bit concerned that this latency might be a permanent thing.

A couple of quick follow-ups: I noticed upon re-reading the 
description that the docs state that, "TIME and PITCH functions 
introduce a latency of 2048 samples...".  But they don't mention that 
the SPEED parameter is subject to this.  Does that mean that the lag 
only affects instances where you are manipulating time and pitch 
independently of each other?

Many of us are used to "tape style" time/pitch-shift by now.  While 
independent control of time and pitch (ala the Repeater) is certainly 
very(!) cool, I think that if the Speed function were latency free, 
it might be possible to get by until the Time and Pitch lag is 
resolved.

I noticed there's not a real Feedback parameter, but I'm a little 
confused with Auto-Fade.  Does Auto-Fade take effect on a per-track 
or per-loop basis?  If on a per-track basis, might it be possible to 
use Auto-Fade as a Feedback function?  Failing that, could you use 
the Delay effect to do true Feedback-enabled looping and still have 
first-loop capability?  Alternately, could a Macro be used to 
gradually lower the volume of each individual track once they're 
closed, somewhat imitating Feedback functionality?

Is there a way to use two of the "built in" effects simultaneously 
(for instance, Convo or Granulateurre feeding into Delay)?  I'm not 
seeing an obvious way to do that, but I may be missing something. 

Any plans for AU compatibility?  Also, has anybody yet tried loading 
in a Bidule Group or Reaktor Ensemble to get a larger, more complex 
effect chain (as opposed to only two auxes)?  If so, what kind of 
latency have they experienced?

Sorry to "grill" you like this, Philippe.  I wouldn't be firing off 
so many questions if it didn't look like an interesting product, 
though.  :)

Thanks!
