Well I down loaded that IS16 IPAD app to see what is was like seems slightly more complicated then Master Fader and if theres compressors on board they had no control in the app there was an assign group page but I didn't understand the routing and with out the hardware impossible self diagnose no control of the effects parameters there was an EQ on the groups but not on the AUX so I don't know if in fact that is the right app or just he control for the big mixer I like he fact hat it had tabs on top so ou could go to an all group view, all AUX mains view. But you could only view 8 channels at a time (have a tab for first 8 then a tab for 9-16) no tap button at all like I said no control over effects at all other then routing and level and type.
