V:1 clef=bass blows BarFly out of the water! If you want to change
clef in BarFly you have to do it in a K: field, so you would write
that as V:1 [K:bass] or V:1 [K:clef=bass] or
V:1
K:bass
etc.

Yes, the two approaches are mutually incompatible.

Yes I've seen that. I thought that came from an early version of
abc2ps. You could do it with macros in BarFly if you really wanted
to - just define V: alto to be equivalent to V:2 or whatever.
