In the early days, the interfaces were so complex and technical, that only engineers could use them.
Some of these early musicians were truly amazing individuals; real renaissance people. They understood the theory, and had true artistic vision. The knew how to ride the tiger, and could develop great music, fairly efficiently.
A lot of others, not so much. They twiddled knobs at random, and spent a lot of effort, panning for gold dust. Sometimes, they would have a hit, but they wasted a lot of energy on dead ends.
Once the UI improved (like the release of the Korg M1 sampler), then real artists could enter the fray, and that’s when the hockey stick bent.
Not exactly sure what AI’s Korg M1 will be, but I don’t think we’re there, yet.
