exs dropout

I've had an issue happen on a few different computers and was curious if anyone else had experienced this. I'm using the last generation macbook pro (not the unibody) with full memory. I upgraded to snow leopard and mainstage 2 and I while I'm playing I'll suddenly start having the exs sounds drop out after 2 seconds. If I restart it's fine. Does anyone have a solution? I've done all software upgrades.

Thanks!

MacBook Pro, Mac OS X (10.6.2)

I was curious - has anyone experimented with placing the samples and sampler instruments on an SSD drive instead of a 5400 or 7200 rpm drive? I'm curious if it's a reading from disk issue. This brings up the question of if it's possible to load the entire sample on load up instead of just the beginning of each sample - this would be suitable for concerts without too heavy of a patch load, but not a good work around for larger projects.


I look forward to anyone's thought.

Hi kazooman2 et al.


I have tried solid state drives, in fact I have tried pretty much everything and have decided that this problem prevents me from using Mainstage.


I have this information to share.


I have used solid state drives and have had the same problem.

Ivory and Kontakt don't appear to suffer this problem - it appears to be limited to exs. (I guess they use their own streaming technologies.)

Logic suffers the same thing very occasionally, MUCH less often, hardly ever in my experience.

It happens on Mac Mini's and Laptops - I suspect Mac Pro's but can't confirm this.

It happened less with MS1.

Running EXS in Ram - kinda works but the load puts other pressures on the machines. Obviously there's no streaming at all then - probably fine for small gigs.


I post in the hope that someone will look at it.

having had this issue for so long, I know pretty well what I need to do to check for it. (Basically you just need to increase the streaming load to a point when the HD can't keep up and keep it at that level for some time)


MS2.2 appears to now have a method to handle these situations. Instead of sending the EXS to kingdom come, it now pops up an error message, telling you that your HD is too slow. Of course there are audible dropouts for a moment, but they don't persist. As soon as the streaming load is decreased, MS continues to work normally.


There are other issues with MS2.2, but at least this one seems to finally have been dealt with.

Here's a possible workaround/solution for some in this thread...


I recently upgraded MS 2.1.3 on a MBP 6,2 running OSX 10.6.7, exhibiting no issues, to MS 2.2.2 on a MBP 9,1 running OSX 10.8.2, and discovered that one of my ESX24 samples would stop producing audio after receiving anywhere from 5 to around 90 note on messages from my controller. It seemed to be isolated to only the one sample, and I didn't seem to develop any issues with long samples not playing in full, thankfully.


After attempting all of the resolution suggestions I could find on-line (repairing permissions, turning virtual memory off/on, switching between 32/64 bit operation, etc.) without any change, I eventually deleted the sample's folder of audio files from the Samples folder along with the sample's instrument file in the Sampler Instruments folder, both saved in the current saved concert folder that I'd moved over from the old machine. As this was just a stock internal sample, the action of removing the concert-saved files seemed to force MS to default to the internal files and the problem disappeared, so far even after MS re-saved the files into the concert folder.


I know this isn't the same issue or circumstance affecting everyone here, but I hope it's helpful to at least a few...
