For my ‘Alternative Interface Project’, I thought of creating a pitch shifter using a Force Sensitive Resistor that would determine the semitone value and the button will act as a switch to determine whether that value will be positive or negative. In order to load the audio and do the actual pitch shift, using the Ess library to create a simple processing sketch should make things easier. In theory, when the audio file is playing, on pressing the FSR, the audio should shift pitch (high or level depends on clicking the button).
