raton interface

Simply put, Ratón translates mouse movements into MIDI controller messages. Those movements are mapped through a user-defineable curve, which can change the characteristics of the mouse's location. Changing the curve can then expand, contract or step the controller messages to match the specific purpose.

Ratón uses the ALSA sequencer MIDI interface, so audio apps such as JACK-rack, MuSE or Rosegarden can use it's controller stream.
