stopping latency temporarily?

Hi!
Could you please be a bit more specific?
When are you getting the latency, is it when you're recording audio or midi input?

My first thought when I read your problem was a problem I had a few years ago. Is it possible you have like a mastering on your main (probably stereo) output?

I've noticed that if I have like a compressor or a limiter on my main output I will get latency when I'm recording audio input. If you do have it simply don't, for many reasons. Just disable all the plugins on the main output and you're good to go.

Sends in logic have a low latency safe mode, but I've never seen that for effects. One of the biggest sources of latency in logic is the Compensation mode, which you can disable in preferences. Have you tried just turning this off and leaving the low-latency mode off as well? It may sound a little funky (depending on your mix) but could work. You could also raise the low-latency limit until the effect you want to use on the record enabled track is active. Through all of this make sure your buffer is as low as you can set it realistically.

Okay, I think I'm replicating your exact question on my system and ignore my previous post. Here's what I am noticing so far:

1. The issue varies with different audio devices and drivers. My threshold for pitch correction plugs when using my Saffire Pro is better than with my USB microphone.

2. The issues seems to be less with power and more with overall latency of signal chains on individual channels. If Logic is making timing adjustments with a lot of the other channels and it needs to deactivate the pitch correction on the live input when in low-latency mode, then it will and nothing can change it's mind.

My most promising solution today was to do the following:

1. Set buffer as low as possible.

2. Freeze all tracks except the live input.

3. Turn off plug-in compensation.

4. Leave low-latency mode off.

This seemed to work to keep the live track with as low of latency as possible without affecting the rest of the mix. I haven't double checked everything so please let me know if it works for you... I'm just a Logic hack. I think I'll make a YouTube video about this later today. Check out my other vids:

Yep,

It's a signal chain problem with plugins that use "look ahead" technology, it's also what "Low Latency mode" was designed to compensate for.

As LM mentions, freezing tracks is your best bet, but I'm not sure if everything is aligned when unfreezing, it should be...however....
