Thx; it checks out fine. I've experienced exactly the same thing, except for me, the latency was gone in all projects. It sounds like it's something to do with the audio driver.... weird issue. You could always try creating a new user account on your Mac and see if you get the same issues? Will try: >different user next followed by >deleting the preference file (though the random intermittent nature of the problem leads me to doubt it's setting related; certainly there is no option in Logic to select: "Add 500 ms delay to your audio input and pull your hair out while trying to remember you selected this button" ) ...& will report back later. Weird indeed. Suddenly out of the blue our beloved Logic Pro X becomes effectively useless.

UPDATE I tried another new project -no plug ins, just an audio track -for a little while it was working without the 500 ms audio latency. Had breakfast, came back, and the 500 ms latency was there (NO settings had been changed!). I closed Logic and opened it again and the latency was gone IN THAT PROJECT. But all the older projects were still "stuck" on the 500 ms latency and will not respond to the same "fix" (as I mentioned, that "fix" use to work on the other projects -but no longer does). Twilight Zone material here.

Yes; thx Other queries: Plenty of disk space Drivers fine (same issues with different interfaces also) Plugins -see next post on new project with no plugins and only an audio track.

Originally Yamaha AG06; after the latency appeared I also tried my Uphoria UMC 1820 which has the same half-second latency. Reading online reveals other users that have experienced this problem have many different interfaces (Universal Audio, etc.) and the consensus seems to be that the root of the issue lies elsewhere. No, it is never ok and is specifically audio latency. It exist in all old projects as well. Logic went from working fine to 500ms audio delay suddenly /randomly with no recent changes having been made to the project whatsoever in terms of plug-ins, preference settings, or etc. The only activity that took place between when working and when not was the audio interface was plugged in + time. Nothing else was changed. There are no plug ins currently in use in the project audio tracks but in some other projects also not working there are. Yes. THANKS for your reply.

Logic Pro X, which was working fantastic for me -suddenly (randomly as far as I can tell) became completely dead and unusable for recording. Apparently many have had this issue; I have tried several "fixes" which worked for others but not me. THE PROBLEM: Was recording successfully in a project with low latency (10.6 milliseconds according to Pref/Audio. *Suddenly* a MASSIVE latency developed for no apparent reason. It is about 500 milliseconds long!!! (half a second). Recording is suddenly impossible. >NO changes were made to my computer. >All plug ins are disconnected -just an audio track. >Pref/Audio "says" the latency is about 10 ms -but it is actually a full half-second. I I had this problem several times before; it always occurred suddenly when Logic was on for say an hour or so. This fix use to work, but for some reason doesn't now. (1) Reboot computer and restart Logic Pro X. I tried the following suggested fixes I found online which have worked for others -but not for me. (2) Restarted core audio (doesn't work) (3) Changed buffer (was 128, tried 64, 32 -doesn't work (currently sitting at 128). (3) Checked recording delay setting -apparently this has sometimes randomly reset for folks -but it was set to 0 as it should be. (4) Created an aggregate device per online suggestion -no change. A clue??? (5) Tried different audio devices -and reading have found others experienced this strange issue with a wide range of audio devices. HOWEVER I did change the input device to MAC's microphone, and it seemed not to have latency then. Any suggestions? Thanks in advance!
