I'm porting this discussion here from another location, to get more interaction and knowledge. As the title suggests, there is a large collection of Fractal users that run into the same problems when using an additional audio interface (in this case Apogee Element 24). Many searches and threads have been read, but I don't feel there has been a true explanation/solution for what is faced.
I’ve had the Fractal FX 2 XL+ for over a year now, and tried various signal chain setups with and without a 2nd audio interface. I’m now running an Apogee Element 24 via thunderbolt, and using the Axe FX as input through USB. Speakers are running out of Apogee. The audio detail with this setup is amazing and my preferred way to run. (BTW iMac 3.5 GHz Intel Core i7 with 32 gb ram, latest OS, Logic Pro X, Ares firmware for FX XL+)
It seems to be a very common problem that when playing guitar through this chain eventually (after 3-5 minutes) the sound (only guitar input) all of sudden goes into extreme latency (2-3 seconds). The quick fix is to restart the track in Logic Pro and all is synced tight again.
Is it a buffering problem? Can the system only handle so much data before lagging behind? Is it a sync clock problem, that is reset when I restart the play track? Or???
I have all hardware set to 48, and have tried varying buffering settings on all of the units.
I’m not that well versed on clock issues, but I'm reading that the Fractal wants to be the clock source, but the only two options are "Auto, AES, and SPDIF" which claims "no clock source!" when selected. Auto is the one selection that seems to work.
I followed one thread where an owner runs his analog out 1 into the front of the Apogee, while at the same time utilizing the USB connection for other features. I'll try that today, but I'll be surprised it that's the problem/solution. It's curious that when running the system without the Apogee and using the USB of the Fractal only, there is no problem. So somewhere in computer and audio interface path, there is something not jiving.
Back to clock source, should that setting on the Apogee be set to Internal, word clock, or Optical? Internal is the only setting that seems to work.
Of course the 3rd entity is the Logic Pro X program, and I'm wondering if there are some key settings there that I'm missing a subtlety on. I've gone through all the Audio preferences many times, tried different buffering, etc. Buffering numbers are: Logic Pro - 128, Fractal 1024. (I tried doubling those recently with inconclusive results).
The obvious question is: "why does it go out of sync when playing guitar, and why does hitting stop and play agin bring it back into sync"?
Any help here appreciated!
Thanks, Luther
