L6: Dropout upon first play of loop after recording

Howdy! Kid Beyond here.

I've upgraded to Live 6, and I'm experiencing
a disconcerting bug with live audio looping.

Live 5: I record a loop in a clip slot, hit its Play
button, the loop starts playing.

Live 6: I record a loop in a clip slot, hit its Play
button, and... there's a dropout (total silence)
upon the first play of the loop. The dropout is
about 5 milliseconds long.

If you download the following Live Pack, you'll
hear what I mean:

I recorded a 2-bar loop in the Drums track
(me beatboxing into a live mic), and then let
the loop play twice.

I recorded the above in the Drum Out track,
which gets its audio from the Drum track.

So if you play the clip "6-bar drums":
- Bars 1+2: the live performance
- Bars 3+4: the first play of the loop
- Bars 5+6: the second play of the loop

Notice the dropout at the top of Bar 3
(the first kick is gone!).

Notice how it doesn't happen at Bar 5
(the first kick is there!).

I did the same thing with a 1-bar loop of
speech: me saying "5-6-7-8."

So if you play the clip "3-bar speech":
- Bar 1: the live performance
- Bar 2: the first play of the loop
- Bar 3: the second play of the loop

Notice the dropout at the top of Bar 2
(we hear only the second half of "Five").

Notice how it doesn't happen at Bar 3
(we hear the whole word).

I left the original loops in the Drums
track for your reference ("2-bar drums"
and "1-bar speech"). The loops seem
fine; it's only in the first post-Record
playback (as captured in the Drum Out
track) that the dropout occurs.

I tried the same experiment in Live 5;
the bug did not occur.

- - - - -

My system:
- Live 6.0.1
- Powerbook G4 15", 1.67 GHz
- OSX 10.4.8
- 2 GB RAM
- Motu Traveler (Firewire)
- Buffer size: 150 samples

Any thoughts? Has anyone else experienced
this? (I sent this to the support staff too.)


Cheers,

Kid B

I've been having the same problem with Live 6.07. Any news on a fix or workaround?
Thanks!
