I never used to be a fan of program updates. I would only update something that had a major list of improvements and such. Now, however, I look on a weekly basis for plugin and instrument updates. I think for me, part of it is because I’m running all 64 bit and am looking for those performance improvements and small but annoying bug fixes, or maybe a few more samples to add to the list. I find that 99.9% of the time, the updates are smooth, and don’t affect my current stability at all, something I used to be really afraid of messing with.
So I was wondering. If you have a working system, do you update your plugs / instruments on a regular basis, or are you happy with your system as is and prefer not to mess with it (excepting major improvements of course).
