I attached my very first SMF (also in Mp3) created with Cakewalk Pro Audio 9.

Arioso by J.S. Bach

Only the Drum and Bass tracks were created with the BK-9. The other instruments were recorded with the DAW.

I was able to record 3 tracks at the same time. I used two BK-9's, one of them was used as a sound module. Very minimal quantization was used.

Enjoy...
