Hi, I'm having some problems with mainstage on my first use and having big time difficulties figuring out what is wrong. I have recorded through my TCE Impact Twin into Logic so I know the Twin and Logic get along but for some reason I am not getting an input signal into Mainstage through my Twin. I can hear my guitar from the headphone port of the twin and it's is coming through the preamp of input #1 on the twin but there is no interaction with mainstage whatsoever. I have checked the preferences for Mainstage and it is set to use the Impact Twin for both input and output. The channel strip are showing no signal. I have rebooted the twin, my imac and mainstage to no avail. Does anyone have any suggestions?
