I'm running Digital Performer 6 here on my main setup. I'm also running DP 4.5 on my old iMac, because Spectrasonics has no update to run Atmosphere on Intel Macs. I have an M-Audio Duo here and a Quattro on the iMac, with outputs running from the Quattro to the Duo. When I run my synthesizer, the Duo receives nothing but harsh, overamplified noise. So much, really, that I thought I might have blown my speakers. They're fine. I added a limiter and lowered the volumes on both computers to be safe.
If I run Atmosphere straight thru the iMac's built-in audio, it sounds fine. But if I run it from the Quattro to the Duo, I get the harsh noise. I've twiddled with the line level in/out buttons on both interfaces. Nothing. I've also tried running audio straight out of the headphone jack and into the Duo via cable converters. No good. It's very, very quiet (-48 db), needs to be brought up with a pre-amp, contains a significant amount of hum, and there's some latency, too. To some people, this is plain obvious.
