I've been setting up an OSC control surface for Nomad in TouchOSC on iPad, and have been stymied by one particular missing feature, control for the Ion/Gio encoders. There are key commands for the encoder buttons (with /eos/key/...), and the Color/Focus/Image/Form/etc selection buttons, but there is no way it seems (using /eos/wheel/<something>) to control the encoder wheels for these.
Also, it would be very useful if the software transmitted the text for the Softkeys, so that a touch surface could relabel them for their function.
