The point of the KORG display is to give visual feedback of audio signals on someone's modular synth without having to fuss with triggering, scaling, channels, and timebase. It's a very narrow problem space and it can be done with something compact and focused for the context in which it operates. A 100MHz instrument scope like that HP is way overkill for such a purpose and will have an overwhelming number of controls and features. Worse, it will be easy to get it in a state where nothing is appearing and you have to fiddle with buttons to just see a waveform-- this is NOT something a musician wants, not ever, and especially not when live.
