scottsigler Posted February 8, 2021 Share Posted February 8, 2021 • First, I've solved many issues because of this board, and I'm so grateful people here share their knowledge. • Second, I did search for this problem on here (and on YouTube, Google, etc.), and I couldn't find a corresponding issue. If I've missed a thread, just point me in the right direction. • Third, I have done a ton of troubleshooting on this, and will list all I've already done as best I can. I feel like I am missing a simple setting somewhere. This can't be a regular problem Logic users deal with, or the software wouldn't be even remotely successful. SUMMARY OF PROBLEM: • When I am using Cycle to make a section repeat, I am getting "Disk is too slow or System Overload" • I have this issue on multiple songs with a larger number of tracks (30 up to 129) • I should have enough processing power to handle this • The same section or sections played when Cycle is off usually do not produce that error. • When the file is playing and reaches the end of the Cycle, Drive I/O shoots to 100%, and/or Core 1 Spikes to 100% • With all bus plugins turned off, I don't get the issue, but I can't consistently reproduce the error with one particular plugin or sequence of plugins activated • I can sometimes get the error with only one track active (the green light), but that is not reproducible every time • Again, with Cycle off, I rarely get the problem MY RIG: • Logic file is on a Lacie Mobile Media Drive (bought from Apple), 5TB SSD, but recording onto a 1TB partition (569.96GB available) formatted as MacOS Extended (Journaled) • iMac Pro 2017, 3.2 GHz Intel Xeon W (1TB SSD HD, 51.54GB available, 13.35GB purgeable) • 64 GB Ram 2666 MHz DDR4 • Mojave 10.14.6 • Logic 10.5.1 • Apollo x4 and UAD-2 Satellite connected via Thunderbolt 3 SUMMARY OF TROUBLESHOOTING STEPS: • I am mixing, not recording any live tracks • Sample rate 44.1 • No tracks are in Live mode • All MIDI tracks have been bounced in place, then deleted, leaving only analog tracks • I get the error on multiple settings of the I/O Buffer Size (but mostly have it set at 1024) • Most tracks have bus sends, with the plugins being on the busses • The majority of my plugins are from UAudio, and are (I'm pretty sure) running on the processors of an Apollo x4 and a UAD-2 Satellite • I have turned off inputs on all tracks • Bluetooth is turned off • Wifi is turned off • All applications off except for Logic, UAD Console, UAD Meter & Control Panel • Process buffer is set to "Large" • ReWire off • Multithreading set to "Playback & Live Tracks." When it is on "Playback Tracks" the problem is even worse • Running on Low Latency Mode makes no difference • Software Monitoring is off • I have tons of headroom in UAD processing (see screenshot, below) • Low Latency Mode on or off makes no difference • No tracks are frozen (as most plug-ins are utilized via bus sends) • Processing Threads is set to "Automatic." I can select up to 16. Setting to "16" specifically makes no difference SCREENSHOTS: Quote Link to comment Share on other sites More sharing options...
triplets Posted February 8, 2021 Share Posted February 8, 2021 Logic file is on a Lacie Mobile Media Drive (bought from Apple), 5TB SSD, but recording onto a 1TB partition (569.96GB available) formatted as MacOS Extended (Journaled) That is not a 5TB SSD, it's a 5400 rpm spinning HD. No way a 5TB SSD costs only 170 bucks. Using 2 partitions on a slow drive is not recommended. Have you tried playing the project from the internal drive of your iMac Pro?

JakobP Posted February 8, 2021 Share Posted February 8, 2021 You have around 5% free space left on your system drive, I'd guess this is your problem, since general recommendations would be at least 10%-15%. I could be wrong though... Quote Link to comment Share on other sites More sharing options...
fisherking Posted February 8, 2021 Share Posted February 8, 2021 triplets' suggestion, and jakobP's point, are both on-point. you could also try resetting the smc on your mac (check apple's support pages, or google instructions for your mac)... and also consider resetting the nvram.

Yeah, looks like I made a big mistake thinking that was an SSD drive. I wonder if that is the core issue. I'll definitely look into that. I will also troubleshoot by moving it to the iMac internal. I assumed I was doing the right thing by getting it off the internal, but since I was an idiot about the external drive, I'll give it a shot.

scottsigler Posted February 8, 2021 Author Share Posted February 8, 2021 And that's that — I copied it to the internal HD and had no problems whatsoever, it's Cycling like Lance Armstrong (so the 5% free space doesn't seem to be an issue in this case). SSD external arrives tomorrow. Really mad at myself for such a dumb mistake, but thank you for solving it for me! Quote Link to comment Share on other sites More sharing options...
triplets Posted February 9, 2021 Share Posted February 9, 2021 Great to hear that the Lacie was the only issue and you solved it! Quote Link to comment Share on other sites More sharing options...
