I was wondering if anyone can help me to resolve the problem I am currently having. My system is pretty simple. I have an IMac running Snow Leopard 10.6.7 and I have an edirol 24 bit 96khz interface. It has been working well until recently. I use garage band to record real instruments and also use a midi keyboard. I had a hard time getting my midi to work but now it is finally working real instruments are not. I can playback itunes and garageband tracks through the interface and I have checked all the midi and sound settings a million times. The input setting are correct and it doesn't seem to work. Is it a Garage band problem or a problem with the edirol installer? I have had trouble with permissions in the m-audio firmware loader which I can't seem to fix. I am really getting frustrated with a pretty simple set up. I would be grateful if someone has had this problem and can offer any advice or fix.
