You have to muck about in /proc/asound a bit.
For example, assuming you know that card 1 has MIDI devices associated
with it, you could use "head -n1 /proc/asound/card1/midi0" to get the name
of the first MIDI device, then cross-reference with
/proc/asound/seq/clients (or the output from aconnect).
It's something of a PITA, but it's better than a stab in the dark, which
is what you're doing now. You can't know with absolute certainty that
hw:1 will be a MIDI device, much less the one you want. Though it
probably will be.
Don't even get me started on duplicate names, especially where USB is
involved. A lot of manufacturers, and I just noticed that Yamaha is one
of them, don't give you enough information to differentiate among devices.
