Can I just be clear on this. Are some people saying that digital summing performed by one application sounds better than when performed by another application? There have been numerous scientific tests undertaken, which have categorically confirmed that digital summing (unless broken in the application) sounds identical in all the major hosts. The only marginal differences occur when one host uses a dithered mixer, where another may not. Even then it's only an issue when bit depth is being changed for processing, and therefore primarily only when plugins are being used. Aside from that (leaving plugins themselves out of the mix) there are NO differences. Digital summing is maths, not some kind of mysterious art-form. If some audio card console makes things sound better than Logic (without passing audio through any additional hardware), then either Logic's summing is broken (which when last tested, it most definitely wasn't), or whichever console or other application is adding some kind of artificial processing as part of the summing process. Sorry, but I'm just waiting for somebody to pop up and shout "why does ProTools sound better than Logic, even through the same hardware?" !!! Amazing how the same old myths are able to self perpetuate .... Jules
