Generally, few of these interfaces allow for real-time effects while tracking. For those that have a built-in effects chip, you may be experiencing a defect? And perhaps your G5 may be balking at trying to create real-time effects for both channels in real time. If you used the identical setup in school, the same way, on the same computer, sounds like a defect? You can't expect everything new from China to work correctly because it doesn't. Everything from China you purchase is a non-quality control crapshoot. So if you have an active warranty you may want to try and exchange your unit. If the same thing continues to happen with a new unit, it's most likely operator error. And only somebody with a G5 and Logic may be the only person to help you. I don't do cartoon interfaces like OS X so we probably need a Mac guy here to help you.

My problem is I will plug it in to my Power Mac G5 and I will hear whatever I plug into the box when i'm on my desktop with no programs open. When I start Logic Pro 8 I will hook it up to it and it will work but when I start using plugins FX I will still hear the clean sounding insturment coming from my desktop in only my left ear of my headphones (input 1). I have downloaded the latest drivers and everything.

Can anyone help me? Anyone heard of a problem like this?

Thanks

Examine the setup without effects a little more closely. Using a single input channel, can you pan this correctly from left to right in your headphones? Does that work for both input channels? Can you set it so that one channel is only in the left ear and the other channel only in the right ear? If so, that means your interface and input to Logic is working correctly, at least at a simple level. Leave the channels panned centrally.

Now when you load and configure the plug-in, have you got it set as a mono-input, stereo-output effect? Where is the mono input taken from? Are both the L and R effect outputs routed to a stereo return in Logic?
