MainStage issues with Midi Keyboard

So far, Mainstage 3.2 is turning out to be fairly glitchy, so it very well could be a Mainstage issue.

But, just to make sure:

What sample rate is your concert set to?

Your computer is plenty fast enough...but since you are using the internal sound card, perhaps try keeping the sample rate at 44.1K or 48K if it's not already.

A few troubleshooting questions.
1) When you raise the sample rate to say, 256 or 512, does the problem go away?
2) Under Advanced Audio settings, is CPU usage set to use all cores?
3) Is I/O safety buffer checked or unchecked? (Try the opposite and see if it fixes the problem)
4) Try changing the sample rate up to 48K, or down to 44.1K respectively, and then back again.
5) Are your MIDI inputs set up correctly in Audio MIDI Setup utility?
6) Try changing the slider to "Less latency" and see if the problem goes away.
7) Last resort, backup all files, and uninstall mainstage and then reinstall it.

Yeah, sorry...that's a frustrating issue. If you aren't having problems in other apps, then that definitely points to Mainstage being at issue. Typically popping and crackling indicates that your buffer setting is too low...but your computer has good specs, so I doubt you are maxing it out.

You could also try maxing out the buffer setting to 1024, just to see if that makes it stop...but it's much more likely that Mainstage is just being glitchy.

I'm having a helluva time since upgrading from 3.1.1.

One more thing...what speed is your hard drive?

There's a small chance that your hard drive may be bottlenecking if it's a 5400rpm drive, depending on what plugins you are using. If the drive is faster than that, then it's probably not the issue.

I'm just covering all bases.

3.1.1 WAS good and stable.

This 3.2 nonsense is the problem.
