I have the TB app on Android and so far only use it for emergencies and scanning posts in a pinch. It is well executed, nice to have, and good to have, but not the "go to" path for TB.
Keep in mind that I am an engineering, geeky, company-guy!!
Then, Mr. Geek Engineer...I challenge you to add a parallel output to the Programmable EQ so players like me can have an easy way to have a split channel board AND EQ presets.
