This is why I suggested snd-seq-dummy; Wine does _not_ use exclusive
connections, so you can add your own connections:

 +------+     +---------+ +---------+     +------+
 | WINE |---->| Through |>| Through |---->| USB  |
 |      |<----|    A    |<|    B    |<----| MIDI |
 +------+     +---------+ +---------+     +------+
                   |           |
                   v           v
                aseqdump    aseqdump

(Without the Through port, you could monitor only data coming from
the device.)
