I know this is a dumb question, as using beta on production is never a good idea, but have you guys who have been using the beta think it is stable enough to use for a gig? Only new feature I'd really be using would be the acoustic simulator on a few songs. Having the acoustic sim isn't super important to me, so if it is really buggy or unstable, I'll just stick with the older release I've been using.
I've always followed the rule of NEVER using a Beta OS for gigs. Followed it right up until last week when I decided to install it - and it later gave me error screens that I couldn't get rid of until the Kemper support team told me how to reset everything. To me, the acoustic sim is a fun toy - but after having sat with it more, I find that's all it is in terms of live performances. Even with EQ, I couldn't get the full body sound that I was looking for and when someone else plays a real acoustic at the same time, it got buried. So (IMO) it's definitely not worth the risk.
