Chuck,
Space is an issue... but with the FFTs in the EQs, when trying to EQ a Kick Drum and a Bass together, it might be really handy. Plus, because they are easy to use with touch, it would be totally fun to have both up side by side and tweak them. The only way I can see to do this is to take a lot of time adding tracks between the two tracks I want to put side by side so that they happen to not overlap.
Frankly, on a 20pt touch screen, one person could work one EQ while another person works the other one.
:-)
Can you agree it might be useful?
