For sequencing, the two-line lcd interface is idiotic, compared to ANY modern software package.
That’s one perspective, anyway.
Other people have a different experience in that the use of a computer changes their focus and awareness such that their musical flow is interrupted. The choice to use a hardware sequencer, even one with a small LCD, is not a choice born of idiocy, but one that recognizes their valuation of their musical process, and how the use of software isn’t conducive to that process. It’s also worth considering the other aspects of the UI design of the CS, and how that may be valued more than a mouse.
I do think your perspective is valid, but it’s true in a necessarily limited context.
