Logic Pro X Major Bugs. Crashing. Weak Audio Signal. Kontakt 5. Balance Interface?

Just purchased Logic Pro X two days ago. I've been experiencing nothing but problems with it. It's consistently making pops and clicks when any audio signal is heard (adjusting midi instruments or actual audio). Audio signal is incredibly weak, approximately -30db quieter than the exact Same gain settings on the interface played in Reason 7 which has worked perfectly until now). Unable to record both midi data and a single audio track at the same time (brought up an instance of Kontakt 5 using the Giant Piano plugin and a simple dry vocal take). I've already had a major crash where it shut down my system, the screen went ballistic and glitched to a grey screen in the background off and on making the system unusable (I did report it to apple). buttons are laggy and clicks work sometimes, sometimes they don't. I have to admit I'm quite frustrated at the moment. Anyone else having these major issues? I'm sad to admit that I am sorely unimpressed with a release from Apple of this magnitude being absolutely unworkable, at least in my case. Any solutions or thoughts are greatly appreciated. Friends with different interfaces that also have Logic Pro X don't seem to be having as many problems as me so it could be a bug between my interface and the program??


I have a spec'd out Macbook Retina running 10.8.4 (2013, 16GB Ram, 2.8Ghz, 768GB) running through Propellerhead Balance interface. I've been trying to run Kontakt 5 as my sampler in these tests.


Kudos to any help!


Cheers,

Hi, Dan.


A few thoughts.


Is the driver for your balance interface 32 bit? Logic X only works in 64, although the sriver is a system function ML is also 64 bit.


Pops and clicks usually indicate a memory problem. What's your buffer size? Does increasing it remove the clicks?


Kontakt will also load isteslf into memory and with large samples such as the grand they take a lot. Remember, OS X, Logic and other processes use memory. Even with 16G you can fill it up.


I'm also wondering if you have an external Hd for the Kontakt sample library. If not, the Hd will be working hard accessing different parts of the internal Hd for samples [not all are loaded into memory, they stream from a folder] and also requests from logic and the OS. This will slow down logic's response time as the Hd is trying to to many things at once.


I hope that some of these suggestions help, and that you get Logic working.

Scorpii,



Some great thoughts.


My latency is set at 256 for buffer size. Shouldn't be a problem, thats a pretty good balance between useable and not making the cpu work too hard. That has worked perfectly fine running both Kontakt 5 and Reason 7 simultaneously with many much larger patches loaded in the past! I think, unless Logic just takes up WAY more processor power, that this setting should fair well with what I'm doing and what computer I have...



As for the interface, according to the Tech Specs on the Propellerhead website, it says:


Technical specifications

  • 2-in by 2-out audio interface
  • USB 2.0 – bus powered
  • Hi-end pre-amplifiers
  • Hi-end 24-bit ADC/DACs, 44.1 to 96kHz
  • Low latency design
  • Clip Safe – Never again a lost take because of inadequate level settings. The “built-in recording engineer” watches over your session and automatically heals any clipped recordings.
  • Works with any audio software. Mac OS class compliant (no driver on Mac OS). ASIO drivers for Windows available from the download page..
  • Built-in Propellerhead Ignition Key
  • Direct monitoring (for stand-alone or DAW use) ...... etc.... etc.....



So I guess this means the interface is only 24-bit compatible?? This came out just last year while Logic 9 was still out, I can't imagine them saying it works with any DAW when it wouldn't work with any DAW. Would this cause the audio to produce such a weak signal as its been doing, you think?I hope this doesn't mean I'm up the creek without a paddle on this one! That would be immensely dissappointing!

24bit is the audio bit-width. It's how detailed the audio samples it takes are and is one aspect of how good a reproduction of any recorded or outputted sound will be. In short, it is completely distinct and seperate from the driver architecture.



If you don't know what 64bit is by now, you've been sleeping.... for around 8 years. Google 64bit vs 32bit, it's very important.


See if the problem still occurs if you use built-in sound. If not, go on propellorheads forums and ask them there as you problem is with your sound card. If it does still happen, let us know and we'll run some tests and hopefully find a fix.

Ah, well unless 'Dan Gore' replies back we will never know for sure one way or the other or if it was a problem specific to him or his system..unless someone else here is successfully using the 'Balance' interface... with 10.8.4 and LPX?


You may want to start and ask that very question in a new thread... to obtain a faster response.


Something like.....


"Is anyone successfully using the Propellerheads Balance Interface with Logic Pro and Mountain Lion?"


..should work...


Have you also checked the Propellerheads forums?


Finally, there are several people on this website that claim they have no problems running Balance with Logic Pro... so check out the reviews listed there. Typically if it works fine with LP9 it should work fine with LPX..


However, as it is normally the OS X version (and CoreAudio compatibility with that version of OS X) that makes all the difference.. and not the app itself... I'd check it works with 10.8.4 first...You could contact Propellerheards themselves to confirm this...

So I have found a solution.. (mostly at least)



I think it was a combination of things happening all at once. Number one being that Logic Pro X just has some bugs. Some of the issues with Kontakt 5 loading slowly or not loading or losing an instrument after being loaded are all just bug issues in Logic Pro X that need to be resolved. Some of these issues have been addressed in the most recent update 10.0.1. However, there are still issues, which is to be expected i suppose on any release of any DAW.


I was in contact with the support people at Propellerhead and they did not know of such an issue or what was wrong. He suggested to try Balance on another computer just to be sure it was a Balance issue (and not Reason or Logic Pro X software issue). I tested it on my friends identical macbook pro retina using logic. He had absolutely no issues in gain or power. (Logic still crashes and has bugs even on his, but as said before thats just some small bug fixes away from being resolved). So I was very confused at this point. Neither Logic or Reason 7 were working on my computer, I knew Balance was compatible with both, but it was still giving me the gain problem. It became apparant that this was a Macbook issue. So I called Apple Tech Support.


The audio issue at hand was discovered after 8 hours off and on the phone with numerous apple support people, none of which had an answer or solution and kept passing me on to someone else until, at last, I was put on the line with a young lady named Vira Golender, a Senior Advisor for Apple tech support on Macbooks. She was prompt, very professional and helped me try numerous things to resolve the issue including some software/hardware power resets (thinking it might be a usb power issue), partitioning my drive and re-installing OSX on the new partition, and re-installing the software one the new partition to see if it worked. This actually worked with Balance. However, upon going back to my regular Hard Drive space where all my personal info is stored, the audio still had the issue. Vira had me try one last thing as it became apparent that it was a software issue on the Macbook. She had me go into Finder and go to the Macintosh HD/Library/Preferences and move the folder named 'Audio' into the trash. It was here the issue was resolved. Mac automatically makes another audio folder. I suppose the old one had somehow corrupted. And I can say with certainty that that was somehow caused by Logic Pro X either at install or sometime running the program. I have not had even one issue with Balance on 10.6.8 up to 10.8.4 using Reason 6, 6.5, or 7 until the day I downloaded and ran Logic Pro X. Clearly this issue isn't happening to everyone but somehow Logic seemed to trip something in the Audio folder and corrupted the audio gain for the whole system.


I am happy to say that Balance is working as it should now in both Reason 7.0.1 and Logic Pro X 10.0.1. Gain levels are accurate and crystal clear like you'd expect. Heck, I even swear the headphone output on Balance itself is even higher than before! Still uncertain of what the actual 'issue' was (or more or less why it happened) but its cleared up for now. I'll keep you posted if anything changes or it becomes a recurring issue.


Thanks for all your input. I pray no one else has this issue. I was as detailed as possible with what happened to me in the hopes this can help out others in the future! And sorry for the late response, Its been days i've been working on the issue and it was just figured out!


Blessings to you all.

Thanks Dan


I have a very complex Mac Pro Desktop setup, made more so by lots of recent changes (Upgrades to Logic Pro X and Mavericks, amongst others, including SSD firmware on three of its drives and a video card upgrade). Luckily I found your excellent writeup on this problem fairly early in my saga. My hair is now in the regrowth phase.


I can add to this that I use an old favourite TC Electronic interface that has not been supported for years. I naturally thought that with Logic Pro X and Mavericks, it had finally reached the end of the compatibility line. One of the first things I did when I noticed the audio problem was to switch Logic to the computer's built in output. That didn't fix it. Trashing the Audio folder from the system library prefferences did (It's not in the user library, in case anyone thinks they don't have one). Thanks.


As a foot note, I thought my TC Electronic Konnekt Live interface was unsupported, but it seens the forum pressure got to them and I just found a July 2013 update. I was running on 5 year old firmware so 64 bit compatability is not an issue. I was wondering about that one.


Thanks again Dan
