How to troubleshoot a VST related computer crash

Hi all,

Nice place you got here--I'm hoping to bounce some ideas and see who might have better ones.

I've been using a Macbook with StudioOne for various performances: I use it as a track player for theater groups, I've used it as a utility synth to play sundry instruments with a larger band/chorus (instruments like glockenspiel, flute, string pads, etc.), as a track player with a live VST piano (Pianoteq). I had a gig last might and configured StudioOne to run one Pianoteq, one VB3, and two Reason rack instruments. It worked fine at home practicing, but crashed repeatedly at the gig. Hung notes, couldn't shut down the program without rebooting.

The sounds I was using were perfect and I'll re-create the crime scene here at home and play like a maniac for twenty minutes or so (the approximate time of the first crash.) I'm looking for advice on how to avoid this problem in the future. At the gig I removed the Reason instruments and I think that might have helped. My controller is a Numa PianoX and it has useable sounds so I wasn't too far up the creek last night, but I want my Pianoteq and VB3 back! The recent Numa piano upgrade gives the instrument a much better piano than the original, but the organs are not doing it for me.

Perhaps I should find a VST wrapper program and not lean on StudioOne for this sort of use? I was using very little of StudioOne's capabilities--no reverb, compressors, EQ. I'm also using a Korg Nanokontrol 2 to give me some control of the organ primarily, but also volume faders for the instruments. Could those control messages, along with sustain pedal and expression pedal, be sending too much data and freaking out the Mac?

I hope to hear from some of you VST warriors and let me know how it really should be done. Thanks

Hi and welcome to the forum!

One important question is whether anything was different during the live performance compared to rehearsals - like running on battery, having other apps open, or Wi-Fi/Bluetooth enabled.

It's also worth checking if macOS generated a crash report. Sometimes it shows which plugin caused the crash. I'm not a macOS user, but you can look in Console under "Crash Reports" or in ~/Library/Logs/DiagnosticReports/.

Since removing the Reason Rack seemed to help, that could be a good direction. It’s definitely worth testing with and without the Reason instruments to isolate any problematic plugin.

Unfortunately, stability issues like this are often a process of trial and error. For live use, it's safest to avoid plugins that have shown any instability. Some plugins behave unpredictably under live CPU/memory pressure or when receiving lots of MIDI data.
