Pitch Fork is a prototype of an alternate, actuated digital<br/>musical instrument (DMI). It uses 5 infra-red and 4 piezoelectric<br/>sensors to control an additive synthesis engine. Iron<br/>bars are used as the physical point of contact in interaction<br/>with the aim of using this materials natural acoustic properties<br/>as a control signal for aspects of the digitally produced<br/>sound. This choice of material was also chosen to affect<br/>player experience. Sensor readings are relayed to a Macbook<br/>via an Arduino Mega. Mappings and audio output<br/>signal is carried out with Pure Data Extended.
