Accordian controlling vowels and constants
Perry Cook and Colby Leider
The SqueezeVox project with Colby Leider of Princeton has revisited the difficult issue of devising a suitable controller for models of the human voice. Breathing, pitch, and articulation of vowels and consonants must be controlled in a vocal model, so the accordion was selected as a natural interface. Pitch via the keyboard, vibrato aftertouch, and a linear strip for fine pitch and vibrato are controlled with the right hand. Breathing is controlled by the bellows, and the left hand controls vowels and constants via buttons (presets), or continuous controllers such as a touch pad, plungers, or squeeze interface.
