Hey so anytime I try to create music using Ana 2 after the Logic Pro X update, I can’t use it on more than 4 channels without sound stopping coming out of my DAW completely. Suggestions?
Is it possible to give us steps to try and reproduce? Also MacOs, LPX + ANA2 versions please
Okay, so I have 4 instrument channels. One is a lead, one is a melody, and two are baselines. Then, let’s say Ana 2 is the instrument on all of them. The sound comes out just fine from the DAW and Ana 2 is working properly. Let’s say I want to add a bass pulse for a new channel, also using the Ana 2 plug in. All of the sudden, with the addition of this 5th instrument channel with Ana 2 on it, the sound completely stops coming out of my daw and all the channels. But when I turn Ana 2 off on the 5th channel; it works fine on only the 4.
- What version of ANA 2 is installed ? (click the ANA 2 logo top left of the gui to get the info screen).
- Is it an Intel Mac or a M1/M2 Silicon model ?
- What macOS version are you running on this Mac ?
- Assuming you’re using latest Logic pro 10.7.9 since you mentioned after the Logic Pro X update.
There’s a couple of things you’d like to check :
- Your Logic Audio settings ( especially the I/O Buffer Size ) + Process Buffer Range.
- Your Logic Project File Settings and the Sample Rate.
- Check the Output for each Instrument Channel : is it going to a Bus rather than Stereo Out ?
- Are you using a template and do you have the same issue with a New Empty Project ?
Just dropped 15 instances of ANA 2 v2.5.2 on latest Logic Pro 10.7.9 here and they’re all playing back without issue.
Seems you had a similar/related issue reported in this other post here as well, so I would blame Logic at 1st, but we need more details about your setup and ANA 2 version.
You can also use the Chat here on the forums ( forum’s page Top-Right icon ) or shoot an email to customerservice@sonicacademy.com and we’ll take it from there 
Cheers
ATTN SA Team : ended up doing a teamviewer session with the end user and issue is confirmed on their end. Still trying to replicate this 100% at my end tho, but might be a possible bug.

I have exactly the same Issue with more than 2 instances of ANA2 by specific presets every time I restart the project. I need to delete one instance, reload ANA2 and the preset to get sound again until the next time I reload the project. I am running a Mac Studio M2 Ultra with Ventura 13.5 and Logic 10.7.9. My system runs perfect with all other plugins incl. SSL, Plugin Alliance, Arturia, Native Instruments, U-He etc sometimes projects with over 60 tracks of Instruments and FX with no issues. I run an Antelope Discrete 4 Pro Synergy Core Audi Interface. Don’t blame Logic as mentioned here…

Welcome to the forums and thanks for your feedback and system details
This issue is still under investigation and the developers are aware of this, but it’s a tricky one to replicate.
-
Could you please let us know what are the presets causing issue at your end ?
-
Are those LPX projects older projects created with a previous version of ANA 2 ?
Cheers 
Hi, thanks for the warm welcome. The current preset causing this issue is “Playable Textures” See screenshot:
These are new projects with new ANA2 version as I have only just purchased ANA2 last week.
Cheers!

I can replicate this with the "“Playable Textures” preset, also on a different system ( Intel Mac with Monterey + LPX 10.7.9 ).
When reopening a LPX Project with multiple instances of ANA 2 using this preset, I only have click and pops and then no audio out inside Logic.
Playable Texture Preset.logicx.zip (238.8 KB)
Pushing this to SA team.
ANA v2.5.4 is Now available in your My Acount/My Downloads/Plugins area 
This should address the LPX issue and audio drop out when using multiple instances in Logic.
