Abstract: A portable multi-functional audio sound system has an enclosure and control panel with an optional display on a front portion of the enclosure. The control panel provides for selection among menu options which are presented on the display. An audio input is coupled for receiving a live audio signal. An electronic circuit receives user commands from the control panel and displays configuration information on the display. The electronic circuit has an amplifier for amplifying the live audio signal, and a synthesizer for generating programmable audio signal in response to a MIDI data stream. The MIDI data stream is routed to the digital signal processor or to the synthesizer. A digital signal processor controls the menu options on the display. A speaker is mounted within the enclosure and coupled for receiving a combined signal of the live audio signal and the programmable audio signal.

Abstract: A tuning device (30) uses a stroboscopic light source for tuning musical instruments (12). The stroboscopic light source is programmable according to the musical instrument being tuned. A first control button (34) on the tuner programs the stroboscopic light source. A second control button (36) enables the stroboscopic light source. A display (38) indicates the state of the stroboscopic light source. A utility device (32) is integrated with the tuner. The utility device can be a key ring, lighter, utility tool, pin light, cell phone, card, watch, jewelry, or audio amplifier. The utility device has a secondary function, which is independent and apart from the tuning activity associated with the musical instrument. The second function of the utility device provides convenience, accessibility, and increases the likelihood that the user will have the tuning device available when needed.
