Benny Greb, well known for his contributions to the drumming education community, shared the approach he has taken to develop his sense of groove and improve his timing on his instrument in his course "The Art and Science of Groove." Now with the Gap Click app, everyone can practice his method easily using this intuitive app! Unlike standard metronomes, which only provide time, Gap Click helps you improve your sense of time. Gap Click is more than a metronome that focuses on improving your ability to keep tempo, become more aware and comfortable with off-beat clicks, and become bulletproof and accurate with all notes of the subdivision. GAP CLICK By scrolling through the numbers of bars and patterns, you can quickly configure a "gap" of time in which the metronome drops out. When the "one" comes back around, will your playing still be in time? How long of a gap can you play through and still maintain a solid tempo? MOVING CLICK Next, you can experiment with all kinds of off-beat patterns in the Gap Bar, which moves the click from the downbeat position to a different location. Can you still play your instrument and maintain the downbeat internally even when you hear the click sound on an off-beat? Both the "click" and the "gap" portion supports various syncopated patterns, allowing you to practice in binary or ternary rhythms - with more or less safety depending on your settings. Features • Ability to choose from various syncopated patterns and the number of measures for both the standard "click" and the "gap." • Use the nostalgic click wheel to find the right tempo or tap to set your desired tempo from 10 to 300bpm • Standard quarter-note time signatures: 2/4, 3/4, 4/4, 5/4, 6/4, 7/4 • Support for VoiceOver ensures Gap Click is fully accessible to users with visual impairments Personalize • See visual feedback for each note or rest that the metronome plays • Accent beat 1 of each measure or turn accents off for a more significant challenge • Flash the screen for a visual indication when switching between the "click" and the "gap" sections • Find your favorite sound from a variety of click samples hand-picked by Benny Buy Once, Use Forever • There are no In-App Purchases - a one-time purchase includes all current and future features.
