hi, welcome to nebula world there are different opinions on that 96khz matter, as you may imagine i personally don't see the benefit, when you work out your sound carefully in 44.1 khz to your ears liking. faster loading is only when you have librarys, that need to be downsampled on loading. there are many librarys sampled in 44.1 khz that just sound great. (some devs are even sampling in all different rates, so you can choose what you need)
the new acqua technology is loading pretty fast in all different rates due to automatic samplerate detection and will load the appropriate vectors automatically.
to work entirely in 96 khz has some cost on hd space and (much more an issue) will cost a lot of cpu, which nebula itself does already. and then there are things soundwise you really have to watchout for, when downsampling for distribution. so it is not only going to 96 khz and all is better, it can also get worse ...
don't want to discourage , just some thoughts. have fun with nebula, best, mathias
