LOGIC PRO LATENCY: WE ALL HAVE A PROBLEM

[cowudders]

I don't see the problem, aside from plug-ins reporting the wrong or no latency figures to the host. Really relevant are the 'latency compensation set to ALL' examples. If there's still some latency, there's something wrong going on ...

All I can say that the UAD-1 and TC powercore plug-ins are perfectly compensated for and I'm on Logic 7.1.1.

And: Always give the plug-in some time to adjust, start the bounce at least a bar before anything happens (therefore your 'weird' 1176 result in the 'Audio, Tracks and Instruments' example). Also stop and start playback in Logic, after you bypassed/enabled a latency inducing plugin. If you don't do this really funky stuff happens.

Yes, MIDI will run out of sync with the 'ALL' option, can't believe they haven't corrected this yet. Must be a problem burried deep down Logic's architecture ....

And yes, you _have_ to disable 'software monitoring' in Logic when overdubbing and compensation set to 'ALL' with a latency-inducing plug on a bus/master, otherwise the newely recorded audio will be out of sync. With software-monitoring 'off' all will be fine (monitor through your audio interface's application).

If you know those 'design-flaws' you shouldn't really run into big troubles.

aside from, .... later.

cheers,

My first test is done without any DSP plugin on a simple audio loop (latency reduction option off) and I get a blank at the beginning of the bounce (look at the one with PSP Mixpressor). But I think with a bigger computer like G5 or Macpro you might have better result than with a G4 2X867 like me. (By the way I buy a Macpro today)

that's right I didn't do this trick all the time.

thx I'm not alone !

Using software monitoring is not possible if you use virtual instrument and effects at the same time; Because to use software monitoring without to much delay you need to be under 128 buffer size....and your CPU will cry...

As far as I am aware of Cubase/Nuendo do not have this problem. Protools I don't know, but I guess neither.

I'm not sure that I ever expected third party plugin instruments like NI or Spectasonics to be perfectly compensated. I have noticed that I have to juggle RMX to get it to sit right sometimes, but I've found this true in PT as well. Some of the NI stuff can be real processor hogs, so I think I'd always check that... though I haven't done as thorough a test as you've done.

I'm intrigued by the tests, but one question... why would you ever want to have latency compensation off? I'm not really understanding why this would be a part of the experiment...?
thanx

Because in logic documentation it says this option is only for DSP plugins users, otherwise you don't need this option, native plugins latency is supposed to be compensated anyway...but it's not !

you will certainly repeat the test on your new mac....dont forget to post the results, please
