Preset, voice, patch, sound... they're all words that have been used for a "programmed sound" by various manufacturers and people through the times. No need to apologize for using any of those
In Arturia lingo it's most often "preset", but "patch" is also used quite a bit - e.g. in the PolyBrute manual, "preset" is mentioned 135 times and "patch" is mentioned 115 times.
As for the actual question, the PB has no feature to start up with the last used preset. It's a feature that I've seen requested a few times. I'll add my +1 for it!
