Some plugins (effects and synths) have a “randomize” feature, basically randomizing their parameters. I realize that that will often lead to unusable results, but it is a great way to trigger creativity and generate some out-there sounds.
So, I’d love a button on the built-in Steinberg plugins to do exactly that - randomize the settings. This could be done intelligently by limiting the randomization to a subset of settings (no point in, say, randomizing the mute button), and might be a way to push Cubase into the fun/creative/experimental realm a bit more.
