Configuration

  • Required configuration : linux pc with multitouch screen.
  • Multitouch gestures (scrolling, zooming, pinch, etc...) shoud be desactivated on the O.S.. Only monotouch events have to be forwarded as mouse events by the O.S..
  • Puredata 0.49
  • iemguts lib externals
  • hcs/screensize external (optional)
  • and a special version of hidio . see here https://github.com/jyg/hidio

Installation

  1. check you have installed iemguts externals library.

  2. put the hidio.pd_linux file (from hidio folder) into your externals folder. Check if it works by opening hidio-help.pd. (If not, you may have to recompile it. In a terminal inside hidio folder, type ./configure then make).

  3. Open the patch multitouch-help.pd.

  4. follow the 4 steps configuration procedure in the multitouch.settings2.pd window. image
