hi

you must put both "devmap" rules in a single filter; actually, only
one filter is active (the "current filter"). Usually it's the last
one you created. The following should do what you need:

	filtnew devcopy
	filtdevmap devcopy 0 1
	filtdevmap devcopy 1 0

(note that a track can have its current filter too; in this case
events are passed through that filter. if the track has no current
filter, then the song current filter is used, try 'songinfo' if
unsure)

yeah, that's because only the second filter is active; it maps the
virmidi device to hardware device. The mapping of the hardware to
the alsaseq client is still on the inactive filter. Putting both
rules in the same filter should work
