ABSTRACT:
An electronically programmable metronome has a footswitch for allowing a user to adjust the tempo over a continuous range without taking hands off an instrument or interrupting playing. A microcontroller is pre-programmed with a metronome click pattern in any selected note duration value. The user operates a footswitch to increase the tempo automatically in continuous increments and to hold a desired tempo. A digital pulse voltage source and acoustic pulse switch are responsive to control logic to produce different amplitudes and tones for three types of clicks, i.e., Loud, Medium, and Soft, in order to provide distinctly different audible click patterns. Headphones, an audio speaker, and/or an LED indicator can be used to provide audible and visual cues of the tempo to the user. The metronome unit includes a display for menu selection, prompts, and visual cues for adjustment of the tempo and selection of types of clicks in a beat pattern. The microcontroller for the metronome unit can be programmed with any combination of time signatures, rhythms, or patterns with desired cues or accents.
