Topic: Fireface UFX+ and wireless MIDI control

Hi all.  I'm looking to get a Fireface UFX+ and am looking for wireless MIDI control for some elements.  I plan to use my iPad Pro (running TotalMix FX) with the required wired connection to the UFX+ BUT there will be times when I'll need to move further away from the unit than a wired connection will allow.

Is there ANY way I can use a Bluetooth MIDI dongle or other wireless MIDI connection option with the UFX+ that can be controlled via iPhone/iPad/Android tablet?  All I'd need would be basic control of channel levels and perhaps the main output level.

I initially thought that I might be able to remotely control the TotalMix FX iPad app via TouchOSC or Lemur from my iPhone but that doesn't appear possible.

Cheers
Gary
