Logic Pro X Latency?

Logic Pro X Latency?

Hey everyone.

I'm using a Kemper into a Focusrite Scarlett 18i8. It's going in via SP/DIF. 44.1KHz. I also have a Line 6 Helix that I'm using via SP/DIF, 48KHz, but also via USB.

I used to get around 12MS of roundtrip latency, now it's 50ms. It's making recording a bit difficult, guitar loops and stuff just aren't in time when I'm looping and tracking.

I've no idea what has happened but could I get some assistance as to what the issue could be. Nothing has really changed as such.

Input monitoring is off. Buffer size is 1024.

I'm using a 2015 MacBook Pro, 16GB RAM. 2.5GHz i7.

Thanks.

Your buffer size is way to high for recording, go as low as you can without glitching, you should be able to do 128 buffer size, if that works try 64 see what happens...

Thanks for the reply. It seems okay at 64. Latency is much much lower too. I think it's okay, but it was around 12 before on 1024 so I don't know what the issue is.

If I can have a higher buffer rate and lower latency surely that's better, right? So ideally I wanna know what changed. Very strange.

But, I'm not monitoring through Logic, I'm monitoring through Mix Control and my USB Interface... Surely it shouldn't matter what my buffer size or latency is, right?

In that case I'd look at your settings for your focusrite driver as this should not be a Logic issue as you are not monitoring through Logic, perhaps turf driver preferences just in case they are corrupt or re-install your drivers!

Make sure you have no high latency plug-ins on your master out of Logic, always record without any...

Thanks, but I don't think it's latency or drivers. I think I know what it is.

There's a setting that basically pre records a few ms so that it compensates for any transient notes that are played at the beginning of recording. It's called Pre Roll. It's in the Preferences section.

That means that at the beginning it pre rolls the recording, but only on the first take. So when I have it set to loop record I'm missing a few ms which is why it seems like I'm missing a bit of the first note/chord. But it's only on certain things I play, which tells me it's probably me.

My timing is very good and on playback I'm dead on the click, but when it comes back round to the start the first bit of the note is gone, which is strange. I'm not sure if it's a processing issue or a bug or me, but I think I'll leave a bar each side when looping to compensate for it.

Unless you or anyone else know of anything?

It's all perfect when I leave a bar at the beginning of the loop. I think it's just a timing issue. All sorted
