i got some answers from the m-audio forum if anyone ever did a search and was having trouble too...
1) To direct monitor on the 410, you need to launch the 410 control panel and go to the Mixer tab. On the Ana 1/2 In channel, turn the pan dials to center and click on teh Out 1/2 button so that it is on.
2) The line inputs are on the back of the 410. If you want to record a guitar you do NOT push the Mic/Line button in. You should also connect to the Inputs on the Front of the 410, NOT the back. Guitar is not a line level device. DI outputs are NOT usually Line level, they are Mic level. Pre-amp outputs are line level. Line inputs are on the back of the 410; Mic and Guitar inputs are on the front of the 410.
3) I don't know the R-09, so I don't know if it will work as a stand-alone converter, but Yes, the SPDIF should work.
hope this helps anyone with the same firewire 410 problems... all seemed to work for me....
merry taping...
