Unfortunately, MIDI is still the #1 bottleneck we have to deal with. And it’s starting to make less and less sense to cling to a 1982 standard. But then again, no one has to courage to just discard it and rebuild it from scratch, because everything third-party (not to mention all MIDI hardware) would become instantly incompatible. But maybe it’s possible to develop a new, truly modern standard that maintains MIDI backward compatibility?
