Who else is dying to use TouchDesigner with an actual touch interface 
?
You could mirror the TD file onto your iPad or you could make an interface with something like TouchOSC
Michael Ilardi has made a great app for iOS named TMote that works brilliantly for doing just this - worth dropping him a message
Considering Touchdesigner running smoothly on M1 Mac would be for sure great to have it running on iPad Pro with the same chip…
Ofc the mouse oriented UX would need loads of refinement but probably running as a touch player fairly feasible…
