This is an interesting topic to me, and I have a related question. I have a Roland FA-08 which has a DAW control mode. I have it set up in Sonar and it works, well, kind of. Most functions (play, stop, record, pad buttons, etc.) work well; however, some functions, like the rotary knobs, do not work at all. I have map any midi messages that I want to those know, but I don't really know what Sonar is expecting. Is there some list somewhere that details what Sonar expects? Would Azslow's utility work for this?
