ABSTRACT:
A laser activated synthesizer system for efficiently translating finger positions on a surface into sounds. The laser activated synthesizer system includes a housing member which encloses a plurality of lasers near an upper surface, each laser aligned with a piano like key arrangement etched into a lower surface, a laser pickup, a control unit and a synthesizer. The lasers are each individually touch sensitive and require minimal effort to activate. The keys are etched in either a 61 key configuration or 88 key configuration. The laser pickup senses the activation of each laser while the control unit electrically connected to the laser pickup determines which laser(s) are being activated and sends the information to the synthesizer to emit the correct note or chord.
