** DISCLAIMER** DJs..... Don't mess with 4k at gigs first off..... or period lol ... this is more an experiment. So before anybody jumps in with "why would you even care about this" ... trust me, I can't explain it atm, but oh boy it's awesome. For some reason, when I drag a 4K file into the sampler (taken from either the iPhone or another source) it quits immediately. Same source material / encoding at anything below 4k (even 2560x1440) works fine. Again, this isn't something that most users would do lol .. doing some experimenting with an idea of mine on a brand new top spec 15" 2017 Macbook pro lol
