Thanks for your replies.
I would like to use 3 mics simultaneously , one of which is a condenser mic that needs phantom power.
Midi is a nice to have, but not required. My midi keyboard has a usb connection.
I also have a Mackie 12vlz mixer that I have been using for the mic preamp in front of the PCI board. If I use one of these newer interfaces, do I still need the mixer?
I used the Echo Mia to record a CD and thought it did a terrific job. Will going to USB be a step back or can I get at least the same sound quality?
Should I consider Thunderbolt?
Thanks for any advice and recommendations.
