Thanks for all of your comments by the way!
As much as I would like to purchase a GLD, it is way above what I am willing to spend for a mixer.
Is there any chance at all the the QU-16 will have 3rd party plugin capability (for live use), in the future? I imagine what that would take is a partnership with 3rd party vendors to develop their plugins for the A&H QU platform. Or perhaps an expansion card could be developed that utilizes the USB-B port for this functionality? I would certainly pay for this feature!
