I'm sure this has been requested, yet searching "random preset" yields the results you would figure
Rather than having to dig through menus to pick what type of sound I'm looking for (I don't like to think of a sound all the time before browsing, I also love to be surprised)-basses sound cool as leads, leads sound cool as basses etc. would love to have a dice button like omnisphere and others to just click and discover magnificence with a random preset...
edit: ooh, what would be really cool on top of this-that I don't think has been done before-would be "every new instance, new random default preset"
