Software Instrument tracks resetting when changing buffer size?

That is just how it works: when changing buffer size, coreaudio has to reboot. This means loading any sampled instrument again. This also happens with EXS24 instruments, it's not a 3rd party only thing.

You just have to make sure before changing buiffer size, that all your instrument settings are saved into their preset, then there's no problem.

What you see in the pic there, is the channel strip setting, containing all plugins including their current setting. That would be overkill. For soft synths it doesn't matter, none of their controls are reset on rebooting core audio, this only happens with sampled instruments that you've edited but not yet saved. If you don't have any, then you don't have to do anything before rebooting coreaudio within Logic.

Is this in Logic X only because I'm not seeing this in Logic 9 under Snow Leopard.

All instruments including 3rd party hold edits when changing buffer size.

You could be right, this is or used to be an issue with Kontakt , and I just developed a "better-save-than-be-sorry" ethic regarding any edits I made in a Kontakt instrument. But it could still be that the reloading after a core audio reboot refers to the sample mappings of the saved instrument, and not the last edits. I'll keep the saving twitch. But I guess I'll also try it out sometime this fall...
