midish tracks can contain events of different devices mixed;
a track is not binded to a particular channel or device.

The meta event you mentioned, iirc, will set the device
number for all events of the track. This is not how midish
works currently; to make the ``export'' work this way,
hackish code changes are required.

as Julien explained, the easier is to use midish native file
format in most situations. There are lots of other
midish-specific settings that don't fit in .mid files either
