I got a mac mini server, i7quad core, all my audio files on the 2nd hard drive.  Mainstage 2.1.3.  In the enegy saver preference pane, I put hard drive and screen to never sleep, also uncheck the hard disk activity so it stays on all the time.


I use a Fireface UC soundcard, run at 48k, latency at 128 samples.  I use Kontakt 5 and Omnisphere as my main Audio Units.


If I don't touch Mainstage for 10-15 minutes, the audio glitches, and the only way to fix this is to restart mainstage.  Else it plays fine even when I change patch.


I see that it seems to be a common issue here, is there any way to tweak this?


Any info would be appreciated. 


Also, how do I download the 2.2 update?  I can't seem to find it on the apple website.



MainStage, Mac OS X (10.7.3)

    You have to pay for 2.2, on the App Store. Lots of gripes about that, but at least its only $30.


    That MAY fix your problem. Sometimes these sorts of problems are specific to an audio I/O and its drivers. In my case, I had been having similar problems with a MOTU Ultralite, but they seemed to have vanished with the most recent version of MainStage and Lion.


    You could try running your soundcard at 44.1 and see if anything changes.

    Downloaded 2.2, I'll see if that works.  I also updated my soundcard driver.  I'll post if the glitches happens again.

    After 1 month of use, I can say that Mainstage 2.2 doesn't work that well.  Still, after a long standby, the audio is glitching.  My workaround to this is to use a 256 samples buffer, with the security buffer enabled.  It feels a little late when I play, not very pleasant...


    Should I update to 10.7.4?  I fear problems, as I saw on other posts with the Lion update.

    This sounds very similar to an issue I had ages ago when I first started using Mainstage.  I posted about my problem on this board and someone suggested that I try a high-quality firewire cable to use with my MOTU Ultralite MK3 (firewire only).  I had serious doubts that a better cable could possibly be the answer to my situation but - for reasons I can't begin to fathom - it seems to have worked as I haven't experienced the same problem since using a significantly higher-quality (and much more expensive) cable.


    I see that the Fireface UC uses USB connectivity so try a high-quality USB cable and see if it makes any difference.....I know it sounds crazy but a good cable fixed the problem for  me.  I use a bunch of different softsynths to play live and am running at 64 samples with safety buffer on MS 2.1.3.

    it is the original cable that came with the RME Fireface.  I updated the driver, don't know why it was that  outdated (v1.62 instead of 1.69) I only installed it a few months ago.


    now 2 days in a row without glitches, hopefully it fixed the problem.

    One new element I found.  I did a change in Mainstage, started glitching a while after.  I hit Save, then the glitches were gone.  I thought I had to restart MS to get rid of the problem.


    I bought an SSD drive, hope it will fix the problem.
