Q: Mainstage with Presonus Studiolive 16.0.2

So I've recently acquired a Studiolive 16.0.2, which is generally awesome, but I ran across something annoying the other night, which I'm hoping someone can shed some light on.

 

 

I had my guitar hooked up to the mixer, which was connected via firewire to the mac, running my normal Mainstage performance rig.  All was fine at first, and the sound was great, but after a while, I noticed a crackling static like sound on my guitar channel each time I changed patch.  It would be there for a few seconds, then disappear.  Then as I continued through my set, the problem got progressively worse, until it remained permanently and turned into a sort of digital 'gargling' sound.  Only exiting Mainstage got rid of it.

 

 

Incidentally, I tried the dry guitar signal direct through the mixer and it was fine.  Also, there was no problem with the playback which was also routed through the Studiolive.

 

 

Any ideas?

MacBook, Mac OS X (10.6.8), 4Gb RAM

    Sounds like CPU overload due to low I/O buffer latency or running to many plugins (Space designer ***** the CPU pretty quick).  Try I/O buffer at 256 and see what happens.

    Thanks

     

    You were probably right.  I haven't had a recurrence of the problem since, but I suspect it may have been as you say.  I rationalised my MS set up a bit, and got rid of some plug-ins (the desk has pretty decent reverbs) and it's been no problem since.

    I find I can run only run max of 2 Space designer plugin instances with the buffer at 128 before CPU spikes on my Macbook Pro 2.66 Core 2 Duo 8GB RAM.   You can see individule plugin usage stats by double clicking the CPU meter in the top of the main window.
