Hi James, > When I plug guitar into the back, the input meters > continue to register, but the outputs don't, and nothing is audible. Okay, now we're getting somewhere. So, you are trying to get sound from a live input. There are two ways to achieve this. One is through Logic's monitoring, the other is through the MIO's direct monitoring. If through Logic, what sort of live input do you have set up in Logic to handle the signal? The two choices are either an input object, or an aux object with the corresponding physical input set as it's input. If using an input object, make sure software monitoring is enabled. If you want to monitor it directly through the MIO box, make sure the MIO control panel/mixer software is set up to route that specific input directly to the output you are monitoring through. Note though that if you do this in a addition to using an input or aux object in Logic, with software monitoring on, you will get a doubled signal. And there will be latency between the two, depending what you have your I/O buffer set at. -------- Eli Krantzberg http://www.nightshiftorchestra.com Almat Productions
