I have gone to Edit > Preferences >Audio>Driver Settings and scrolled to Mixing Latency. The buffer adjustments are grayed out.

If I understood your original post, the issue was with latency during recording.


To adjust your ASIO settings, you would set the sample rate and buffer size in the Presonus driver interface, try 44.1 and a buffer size of 64 or 128.


Then, go in to Sonar Preferences>Audio>Driver Settings, and make sure the sample rate matches what you set it to in the driver interface.


I have a Presonus interface, the Audiobox 1818 VSL, and I have no issues using 44.1 and a buffer size of 64.


Hope that helps - the other comments about plugins that have 'look ahead' processing, such as Perfect Space, etc, are also valid.  You can test this by temporarily removing effects from your guitar track, and just play the raw signal while recording.  If you hear no delay, then the issue would seem to be with one or more of the effects you have plugged in.

Sorry - forgot to mention, with 44.1 and a buffer of 64, my total round trip latency is 4.1 milliseconds, which is fine.

Bring up the Presonus' control pannel applet... and change the ASIO buffer size to 64-samples.

Dank - Just to clarify, are you saying the audio from your guitar sounds delayed WHILE recording, that is there's clear delay between the time you pluck a note and the time you hear it, or does it sound fine while you're recording but then is delayed during playback?  If it's the latter I'm having a similar issue with X1 behaving differently than Sonar 8.5 (and appears to be related how X1 calculates ASIO Reported Latency).  I just posted a question asking for advice, but may just use the manual adjustment.

At those settings, that's better than fine... 
It's excellent!
 
Most of the better units yield about 5ms total round-trip latency at those same settings (64-sample ASIO buffer size/44.1k)

Bob and Jim,

Please excuse my idiocy, but I could not find the Presonus Firestudio Project control surface on my computer. The only thing I have is Presonus' Universal Control which does not offer a buffer setting. 

I did go to the Presonus website, and I found no other application to download.

For what it's worth, I went to another song I had been working on, and I had no problem laying down a guitar track. It is only that one song!

Oops. I just found it! I will try what you guys recommended.

Then it's got to be a latent plugin causing the problem.
 
Latency comes from two sources:

• Audio Interface (ASIO buffer size)
• Latent plugins (Automatic Plugin Delay Compensation delays all other audio to maintain sync)

If there's a latent plugin inserted *anywhere* in the project, all other audio will be delayed (including the track you're trying to record) to maintain sync.
 
Note:  Some users have mentioned that they've encountered a "corrupt project" where "when latent plugins are removed" auto PDC doesn't remove the compensation delay (causing tracks to be permanently out of sync).  I haven't encountered this issue.  If this is the problem, a workaround is to copy/past all the clips into a new/fresh (empty) project.  Save this new project, and you should be good-to-go.

Hmmm....adjusted to 64 and got the Blue Screen of Death. This is not my night.

J Hughes, I experience the latency as I arm the track to record. It is not yet recorded.

Jim,

I am trying to understand what you're saying about a latent plugin. Do I go to each plugin on each track and turn it off? Certainly, I would like to find the problem and understand what caused it before I copy and paste everything into a new song.

I never realized that plugins were this complicated. I always thought of them as essentially "plug 'n play."

This is what I get for going to law school instead of recording school. But that was 28 years ago. I digress...
