Yes, but it's amazing how many digital synths still in use today don't
even produce CD-quality sound - the M1 runs at 32kHz; the DX7 even
lower (and with fewer bits).

It wasn't always thus - remember the PDP-1?

I don't think the Forth philosphy would encourage automatic anything -
what it does is make it easy to go across levels.
