I love MIDI bass! I'm a keyboard player so I've been using MIDI since it was invented in 83/84. I had one of the 1st MIDI studios in the DC area using a Commodore64 computer.
And the 'role' of bass isn't limited to the electric bass guitar. We're the 'newbies' to the game. Tuba players play bass too. It is a role first.
And a lot of current electric bass players are playing the instrument but,...
not the role of bass.
As a role, bass is very specific. But as an instrument it's wide open.
