I spent yesterday dealing with numerous Kemper crashes (Rig Manager not running), the first I've ever encountered in a platform that's overall highly stable. Comments from Kemper folk on various threads I've read hypothesize that a high number of MIDI messages, such as a burst that can result if your DAW is set for chase, could be the trigger.
I consider the Kemper to be a mission critical application as no one can afford a crash in a live performance. With that in mind, I would respectfully submit that error handling should be a high priority when there's a known vulnerability. If the Kemper is unable to process a high volume burst of MIDI messages, it would be far preferable to simply ignore the ones that can't be processed rather than crashing the unit and causing a time consuming reboot in the middle of a song.
Like a lot of the folks here I make a living as a software developer, so I'm well versed in the art of the possible. I do understand that you can overwhelm any system with too much input data. That said, I think it would be useful to anticipate this in regards to the MIDI input stream and handle the error more gracefully rather than allowing a buffer overrun or whatever it is that's crashing the OS.
I realize error handling isn't as sexy as a new feature, as we all love shiny objects. Nonetheless, sometimes it's worth a little time on these things to keep the reliability factor high. I doesn't matter how many features there are if your Kemper crashes on a gig.
Much respect to the devs and support folks. This is an excellent product, and it's the first time I've dealt with a crash. I know there are lots of other things slated for the next release, but I'd be most grateful if a review of the error handling for MIDI was a part of it.
