Issues with monitoring guitars in Logic Pro

Hi, I decided to get back into recording after a lengthy break.

I'm using a Scarlett 2i2 interface. My Roundtrip latency is 7.6ms and the output it 3.7ms.
If I monitor through the DAW the delay is too distracting to be able to record my guitar effectively.

I haven't noticed this too much in the past and it hasn't been enough to distract me. I'm wondering if I'm missing something or if there is a problem with my audio interface.

I'm using SoundSource, I'm not sure if that can cause an issue with monitoring or not.

I'd be grateful for any advice anyone maybe able to give me. Many thanks.

Kevin

Do you have Direct Monitor engaged and software monitoring disabled?

Hi, no. I'm monitoring through Logic Pro.

Funny thing is I tried making the buffer 1024 which made the roundtrip latency up to 49ms and it improved. Now it doesn't matter how I set the buffer, I can't hear the difference in delay between the various sizes. I'd expect the to be a massive difference at 1024.

I think it is sorted now. Funny how you can spend hours going through things and then when you just try something on a whim like that, all seems right. Hmmmm

Thanks
 
7.6 equates to moving a loudspeaker from next to you to about 8ft away - as in an everyday copeable delay. Most guitarists have at least that amount of delay between their guitar and the cab behind them.

I suspect if you are struggling with the delayed sound, it must be more than what the DAW is reporting. Could be drivers need updating or you have very strange buffer setting that are adding hidden delays outside of the DAW.
 
So, I got up this morning looking forward to playing latency free and to my disappointment, things were just the same as they were.

Which lead me to wondering if I did actually achieve anything or whether I was fibbing to myself.

Yesterday I had an idea that it would be a good idea to uninstall SoundSource. I didn't and wish I had.

I tried GarageBand on my ten year old MacBook Pro with an old Roland interface and surprise, surprise it sounded great. Tried the Scarlett on the same machine and it sounded fine.

It was only then that I uninstalled SoundSource from my iMac. Instantly perfect. Wow all of this time. Could have saved myself hours. Amazing what a time soak these issues can be.

There are no third party drivers as it is taken care of my Mac Core Audio.

But thanks.
 
Sounds like soundsource is your issue? Never heard of it to be honest? What were you using it to do?

SoundSource link.
I was using it to dial in my monitors via eq. Having Logic installed, I could use the parametric eq. I had treated my room and thought I'd tidy things up with that.

I'm just playing now, I can't put my guitar down. The sound is amazing. Looking back I don't know why I didn't get on it sooner. I usually get over obsessive when there are problems to solve and often sit up way into the night.

In fact, it doesn't matter which buffer size I have I can't get any latency. Not that I can hear. I've heard some say that humans can't detect anything below 10ms.
 
My limit is about 11mS, my concert pianist friend seems to detect something at about 9 - not the 'delay', but when he presses the weighted keys, what he hears does not match his fingers. Pianists are never more than a foot or two from the sound source - unlike everyone else with cables!

I feel 4mS latency easily - when it gets up to 9 -12 mS it is offputting to me - and it’s exactly like you piano player friend says - its the strike on the strings that doesn’t match the sound in my Headphones - I have my Buffer set 64 Samples - which gives me about 2.5 mS roundtrip - is that what you are talking about?
 
I think it's what you get when you play. If you play, say, acoustic 6 string - it's a short distance to the ears, so you learn how you twang and then hear it. An electric player has the amp to ear latency which can be, on stage, considerable. Piano players don't like distance. Brass players (especially trumpet and trombone, NEVER hear direct, always reflected so does that mean they learn and develop with higher latency than a violinist has - with the damn thing stuck under their chin!

I can play my friends piano in my average way fine, but faced with longer system latency, he just cannot play properly and makes mistakes!
