Is anyone using two Aardvark Q10's in their rig? I'm considering adding a second one to mine but I'm concerned about my PC's ability to handle the additional load. I have a Pentium 4 1.8 GHz machine. Will I need to upgrade my processor too? I was also wondering if the control panel will recognize that there are now 16 channels and display them all at once or will I constantly have to deal with 1-8 on unit A separately from 1-8 on unit B etc? Plus I'm using SONAR 3 and I wonder if it will distinguish channels. Thanks.
