Also, would like to add on a topic of perfection.

I read about Genos, that even a slightest move of a slider instantly affects a keyboard's parameter. For example, if a volume slider is set to zero, then you turn on the keyboard and start to play, but then even by a mere shake the slider is moved - the volume (or other parameter) is set to almost zero!

So I checked it on Juno: the first changes of a knob or a slider are ignored - so you have to really move it intentionally.

This is how perfection is not really guaranteed no matter how much you pay. But at least at reasonable prices you are more ready to compromise.
