here was Ingo's comments in the "Live sound quality" thread - I think the one Longjohns was referring to where he mentioned using beats was a different one but I cant remember what it was

Some remarks concerning unwarped playing
for warpmodes when the file tempo equals song tempo:
Unfortunately there is currently no indicator in the gui when
file tempo or song tempo are cut of after the second decimal.
So they might well differ a small amount, even though they
seem to be equal. This is what i assume to
be the case shown in the video.
In fact, even for such small differences in the tempo
this will not immediatly lead to warping for most warp modes,
they propably will make a different decision as to what grain
is played at some points but for most of the time will just
play unwarped with a constant sample offset resulting
from such decision.
There seems to be a quirk in the "tones" warper that
causes such an offset quite from the beginning.
"Repitch" starts pitching the sample to accomodate the
small tempo difference, and in effect diverts
more and more from the unwarped sample.
"Complex" mode is different from all others in that it
does no "grained" playing of the existing material.
It performs a time base analysis and transformation
of the input material. Furthermore "complex" also
does the resampling necessary for
sample rate conversion. In effect it diverts in almost all
cases from the "unwarped" sample.
Independed of the above i experienced single sample
offsets (from jitter) between warped and unwarped after subsequent
starting and stopping with "Shift+Space".
For the time being (meaning as long as there are no
envelopes for unwarped clips, no "clip tempo to song tempo" button)
i suggest the workaround:
- use more or less integral clip tempo
(equaling song tempo, naturally)
- use beats mode
I hope this was helpful,
