extrememixing Posted November 16, 2017 Share Posted November 16, 2017 I've been a Pro Tools guy forever, but I have come to really enjoy Logic. I am using Pro Tools HD Native hardware as a core audio device in Logic Pro X 10.3.2. I have a harp overdub session this week that is in Logic. I just checked and compared and the latency with the same 64 sample buffer setting is about 3 times longer in Logic than in Pro Tools. In Pro Tools, things are still usable with a 256 buffer! In fact, that feels better than 64 does in Logic. Why is that? I have an Apollo Twin Thunderbolt that I can use, but I'd rather use my normal path going in--Neves to a GML Compressor--rather than the mic or line inputs on the Twin. The in and out of the Apollo are actually -10, not +4! My Pro Tools hardware also integrates better with my headphone and playback system. But I don't like the latency, and I don't think the player will either! Any suggestions? Is it just the way that Pro Tools hardware works as a core audio device? Thanks for your suggestions. I"m going to set the Apollo up and see if that's a better way to go. Steve Quote Link to comment Share on other sites More sharing options...
extrememixing Posted November 16, 2017 Author Share Posted November 16, 2017 I just hooked the Apollo Twin up. Way less latency than with the Pro Tools interface... But the Apollo doesn't sound as good. I'm going to look in the Audio/Midi set up and see if there are any settings there. Steve Quote Link to comment Share on other sites More sharing options...
David Nahmani Posted November 16, 2017 Share Posted November 16, 2017 It all depends on how the driver was written. Obviously Digidesign/AVID cares little about their Core Audio drivers. Quote Link to comment Share on other sites More sharing options...
extrememixing Posted November 16, 2017 Author Share Posted November 16, 2017 Thanks David, I think you're probably right. And it sucks. Steve Quote Link to comment Share on other sites More sharing options...
Solution extrememixing Posted November 16, 2017 Author Solution Share Posted November 16, 2017 I got the answer over at the DUC. Go to Audio Midi Setup. Select the device. Then click the gear at the bottom and select configure device. You set the hardware buffer size there. I set it to 64 and all is fine now. I wanted to post over here to spread the word to other users. Steve Steve 1 Quote Link to comment Share on other sites More sharing options...
Eric Cardenas Posted November 16, 2017 Share Posted November 16, 2017 Thanks for the report on the manual buffer setting. Is this a separate safety buffer setting? Quote Link to comment Share on other sites More sharing options...
extrememixing Posted November 16, 2017 Author Share Posted November 16, 2017 Eric, It was adding 256 to whatever buffer that I had set in Logic on the preferences page. That's why it seemed to be changing things but not making it much better. So to confirm, the buffer size that is set up in the core audio settings ADDS to the Logic Preference setting. I have them both set to 64 right now and will see how that goes with the session running. I may have to make the one or the other longer at that time. It's a relief to know that the HD Native hardware has entered the realm of working well enough to actually use with Logic Pro X.

xgman Posted November 17, 2017 Share Posted November 17, 2017 What is the default of the core audio buffer settings. I never even knew the system audio/midi had a buffer setting separate from Logic. Quote Link to comment Share on other sites More sharing options...
Eric Cardenas Posted November 17, 2017 Share Posted November 17, 2017 It's just for the Pro Tools HD Native hardware. Quote Link to comment Share on other sites More sharing options...
TomBur Posted August 5, 2022 Share Posted August 5, 2022 This helped me a lot, even in 2022 with a new computer (Mac Pro 2019). The problem didn't exist for me with the old mac pro. I am oscillating between pro tools and logic. Of course pro tools has no latency. But in logic it suddenly sounded like 256 samples delay although I set it to 32, 64, 128... You know that comb filter effect you hear when you try to record your own vocals with not overly loud headphones. Audio Midi setup was in fact set to 256 samples delay, just as I heard it. I never knew that AMS behaves something like a "sample delay master for DAWs other than Pro Tools". Maybe in my old mac it simply was set to 64 and I never touched or even noticed it. It's a strange world. But thank you all for bringing light into dark. It is a slowly developing love relationship with my new mac. We're ten months in and I am solving problem after problem. Next I have to find out why certain plug-ins like Melodyne or Split EQ crash pro tools or at least give me warnings... Quote Link to comment Share on other sites More sharing options...
Zachchapel Posted July 9, 2023 Share Posted July 9, 2023 I had a similar question regarding this topic with Logic and HD Native. Although I finally figured out the buffer settings for the Avid device must be set separately using Avid Audio Server, I still have quirky behavior in Logic. For instance, I could open the same project one day, do some work but not change anything in regards to plugins and inserts, then the next day when I go to work, my channels with hardware inserts (using the I/O insert in Logic) sound a bit funny...I ping them with I/O and it will change from +117 to something like -80 sam. It changes all the time and nothing seems consistent about it. Settings in both logic and the HD Native hardware are the same. I usually do a song-per-project file and use the same template...and even the latency on the I/O inserts in every song changes which are on the same channels in each project/song. Nothing is consistent and it seems random. Any insight would be appreciated and thanks! Quote Link to comment Share on other sites More sharing options...
