Redpipes consists of a chanter which, instead of finger-holes, is equipped with sensors that identify the position of the fingers.
These sensors transfer signals to microprocessors inside the bag of the instrument.
By applying pressure with the arm the player can start and control the chanter and drones, as well as the overblowing function.
The pressure that has to be applied to the bag can be adjusted, which allows players handicapped by age or physical restraints to play the instrument easily.
The bag must be filled with air before starting to play, either by the breath of the player or automatically.
