this issue is quite depressing for me because i must choose betwen delay compensation on or off ..and then.. to choose what kinds of troubles i prefer ... :cry:
so it will be nice that ABLETON make a note about that and tell us some good workaround, advices etc...

IMO, its a bit sad, that live cannot allows you to use third parties plugs efficiently and that we have to wait for live 9 for a rock solid timing ....

Totally agree with that but ...

are you even sure of this ?

Lots of bugs have been reported several times since earlier versions and are still going on, so I'm really wondering about it ...

Is there a list of latency inducing VST/AU's out there somewhere?

So this is what the problem is. I've encountered this in a couple of sets, a few times chronically. I thought I was going mad...
Very disappointing.

There are a few threads going about this:

From Angstrom in another thread:
Quick note: all ableton "hiQ" devices (and the overdrive) have uncompensated delay in order to oversample. Any LPF parallel phase cancellation effect is due to that offset.

#2 PDC is inactive on return channels with their own send activated.
And here are more tips:

Yeah I read those but they hardly help. Of course I could freeze flatten or export everything to a new project or a different program but that's not really the point when people have paid a lot of money for something that doesn't work properly at quite a fundamental level.

In regard to Angstroms tips: What about setting plugs from hiQ to lowQ, would that help? Hmm.

About complaining. Its been going on for such a long time now that im not really expecting anything to happen soon. The only way it might get prioritised is if we gather user emails for a big complaint. Im sure if we gather a few hundred email signatures, they would pay attention.

Does this have effects on pure Session view live performances too?

because I often encountered this one problem:
{
I loop live instruments a lot.
my global latency is at 64 Samples.
that's around 2 milliseconds
(wich close to NO latency while playing)

but once the instruments are recorded and
looped, they are off by 40 or more milliseconds!
a lot (huge LOT) more than the overall latency.
}

I always wondered, why no hearable latency
while playing, results in such a huge offset!

I am amazed that some users manage - or say so - to run Live at 64 samples per buffer.

9/10 producers that I know complain most of the time (included me) of the impossibility of using Live at less than 256 samples. And they are no idiots.

Who cares of PDC. I am making a serious effort here since I get clicks at 128 SB with jsut 2 tracks

on a Macbook Pro 2010 ...


Can anyone explain me? since I complained already, but the answer was "too many m4l devices".
Well, only 2 m4l devices and only 2 Audio tracks with no send/returns ... ok I stop here otherwise I get vulgar...

Not sure I understand this bit

let's say you got some audio track with a high latency vst such as a linear phase eq, and then a timed effect like beat repeat thats goes weird cause of the latency. if you render as audio the audio + eq result and drop it on a new track, you won't need the eq anymore, and will be able to beatrepeat it in various way and it will work correctly.(just an exemple)

Jabon: What kind of audio interface do you use?
The RME fireface for example is known to be very fast.
that's why i bought it in the first place.
If I run Live on my mac without a nice audio interface,
I too need bigger buffer size, of course

thanks for the interest, but with such a light project anything should do.
Actually I think my G4 could handle it too.

In general though it happens with high speed professional equipment.

I run everything via light-pipe to an external converter for ADC/DAC conversion tro8gh a FW device.

There is NO problem with other sofwtare at very low buffer rates .

But this happens even with the internal audio card and a pair of headphones too.
And mainly it is hapopening to other producers.

thanks again though, I am not an RME fan, but they are huge pieces of gear ;-)
