GuitarExtended Uses Arduino and PD to Control Effects
GuitarExtended is a multi-effects system that can digitally alter the sound of a guitar using PD. The user has a box with multiple switches on it that change the alteration to the sound, and the variables of that sound are controlled using a homemade expression pedal with the help of Arduino.
One of the differences in this setup as opposed to other similar examples, is that the resulting tone is sweet and lyrical, as opposed to gritty and bit-smashed. Check out GuitarExtended’s site for more info and documentation.
