Ugh…I hate registry edits and “tweaks”
I usually try to keep my “performance laptop” internet free, and as close to a clean install as possible. I treat it like a piece of gear. I don’t lounge around surfing myspace on my $2,500 piece of gear, simply put. It’s fresh, clean, and pristine. I have 5 laptops and they all have their different purposes, not to mention my desktop computers. Much like I have hardware synths etc that have specific needs. I don’t drag my virus onto my bed to ‘mess around’ with music, it stays on the stands, but my microkorg? Sure, i’ll drag that around and play around because that’s what it’s for!
If you’re getting to your gig at 11pm when you’re supposed to be on at 11:30 rushing to get set up, etc then theres a problem. You should arrive early, set up early, get things prepared, have things sectioned off, etc.
However, an example of ‘worst case scenario’…
a) I was playing Keys with a synthpop band and we were the headliners. Some asshat decided he was going to move our synth without asking so he could have more room. Well he ripped the TRS cable in the jack and we werent going to be using that synth that night. So we scrambled with one of the other bands, they pulled their synth off the stage and I sat and programmed a few quick patches that were close to what i needed, and seeing as we were on in 20 mins, i rushed it, missed a few patches…so we just kinda winged it. paused a bit longer between songs, and did our best.
Had I had a full hour, I always bring my soldering iron and toolset with me, so I could have easily fixed the synth, but there just wasn’t time.
So yes, worst case scenarios happen. However, assuring you’re around professional people, you take GOOD care of your gear, and come prepared, you wont ever find yourself in a bad situation.
I would NEVER barrow someone else’s laptop though. Most folks don’t have a philosophy like mine where the stage laptop is ONLY that. and even then, if someone asked me to barrow my laptop i’d probably laugh at them and say no. “well i’ve got an external drive” my response would have probably been “well you should have brought a working laptop too” the laptop is a TOO easily mistreated VERY expensive piece of gear, and considering that SOOO many people treat them VERY poorly I have absolutely NO faith in the end user treating it like I treat mine. Their laptop just got dropped or booze poured on it! That doesn’t give me a ton of confidence in how they’ll treat mine!
So my vote is still for “your laptop BETTER not break” Sure, contingency plans are good, but it’s like asking a guitarist what they’d do if their guitar got smashed before their show. Not a whole lot to do, except make sure your guitar doesn’t get smashed!
