Meet LinnStrument: a multidimensional sound generation tool that sends MIDI messages over its MIDI or USB jacks to your software or sound generator. It captures 3 dimensions of your finger’s movements polyphonically to give you a greater degree of musical expression in comparison to regular MIDI keyboards. LinnStrument’s notes are arranged like stringed instruments.
LinnStrument is easy to play and gives you more flexibility when experimenting with music. It should work with any MIDI sound generator. This is based on an Arduino platform. The above videos show what you get.
