Maybe you don't know, but the good old knobs and Moog machines have disappeared because this DX7 machine came out. In a way it has broken something in the equipment field.
Moog, ARP, and many other great names are dead just because of this DX7.
I still like the DX7. But ask Bob Moog about it... Maybe it wasn't worth it after all. Now the brands are realizing that the knobs and analog machines are the best, so all the new machines are simulating them.
my 2 cents
