that's not possible with the old-style filtxxx functions, the newer
filter functions are part of the snapshot, here:

	http://caoua.org/midish/midish.tar.gz

they allow to do the ``program change part'', as follows:

	fnew myfilt
	fmap {pc {0 1} 5} {pc {1 1} 15}

mapping program changes to controllers is not possible.

If device 0 is a keyboard, you'll probably need a default mapping
for non-program change events:

	fnew myfilt
	fmap {any {0 1}} {any {1 1}}
	fmap {pc {0 1} 5} {pc {1 1} 15}

Also note that midish counts channels from 0..15, and not 1..16.
