Arduinocaster is a an Arduino based MIDI instrument modelled on a guitar sometimes called a keytar. It uses switches and LEDs to control six "strings" which are held down in guitar like chords. Triggering the strings is through an opto reflective switch for a continuous repeating strum and four touch sensitive switches for a one off sequence. There are three banks of four picking / strumming / arpeggio styles and a three octave capo. Voice change information can also be sent. The music is "Banjo Tricks" by Found from the free download Etiquette CD. Full code and construction details will follow within the month.
