Wish this did not take so long to try out :- Was not so bad. No more undefines and get my UM1 usb and the ens1371 just fine. snd=mu401 does not load with same error as in 2.6.12 kernels! The audio plays through the ensonic just fine. I used to be able to "cat" the midi from the UM1 cat /dev/midi1 but this did not work. Since I had no midi out, I could not try playing MIDI or "thru"ing the keyboard using jackqtl to connect the UM1 to the mpu401. So ... 1. Debian stock kernels are not built with alsa's core. I needed to roll my own for this. 2. The mpu401 problem remains from 2.6.12.
