Non-auditory Feedback

In using computer to make music, we have gained a large degree of control over the sounds we can make and coordinate. But with almost all computer music experiences, there is something lacking that the traditional musical experience is rich in: non-auditory feedback. Mostly this feedback is in the form of haptic sensations such as vibration, but the traditional musician can also see many of the workings of the sound generation in action, i.e. the movement of a guitar string. These two key methods of providing feedback, haptic and visual, are available within the Pd environment, which enable Pd to provide rich, instantaneous feedback. In effect, using non-auditory feedback opens up unused input channels to the brain.
