SMF Import question

Having trouble when importing midi tracks.
Seems to blow away everything - filters, inputs, outputs, tracks.

What's the best way to retain all maps and just import a midi track?
I've got a routing/mapping setup that I'd like to be active under all
circumstances,
freely importing SMF drum tracks/patterns, etc.

Thanks!
