[linux-audio-user] Setting OSS emulations using .soundrc?

I have three "cards" 1. An ens1371 -- oldie but goodie fished from the can (as my dman2044 has no alsa support). 2. A Yamaha sw60xg. Midi sound generator, run through snd-mpu401 (Yamaha recommended such in w2k before they had a real driver). 3. A Roland um-1 USB MIDI interface. Applications that let me choose my routings work fine. Jack is great. However, many OSS oriented apps simply default to the /dev/??0 as default. In my set up, audio plays but of course, MIDI does not. Nor can I get MIDI input. How might I set things up so that the default output /dev/midi0 references the Yamaha, now referenced in /dev/midi1, for instance and the input references the um-1, now /dev/midi2 ??
