Finally, Rhythm+ is here! After many years’ experience as musicians, we’ve never found a metronome that could do everything we wanted, therefore we are proud to present Rhythm+. Rhythm+ is an extremely accurate, user-friendly metronome packed with features and boasting a simple design. In Rhythm+ there is emphasis on easy accessibility, so no maneuvering through menu after menu cluttering up the screen. Offering everything the best professional metronomes do and more, Rhythm+ has a very intuitive β€˜Pendulum Mode’ where you can make and adjust rhythmic figures. In pendulum mode as well as working with common beats and subdivisions you can access more advanced polyrhythmic functions, a unique feature to Rhythm+. What we consider to be perhaps the greatest strength of Rhythm+, (and where it differs from the best of the other metronomes), is the β€˜Rhythmic Notation’ mode. In the rhythmic notation mode, you are not limited by a selection of ready-made rhythms, but with a clear β€˜note keyboard’ you can input exactly the rhythms you want regardless of how complex. Working with up to 4 simultaneous staves (and as many bars as you want) you can easily input simple rhythmic patterns or complex polyrhythms. So, on the one hand you can input a drum groove (hi-hat, snare bass drum etc), alter the feel with flexible swing features add repetitions or even meter changes; and on the other hand, you can create your own time signatures to work with, create irrational rhythms, tuplets within tuplets and a myriad of other unique features. Regardless of the mode you work in, with Rhythm+ you can automate the tempo and select from a range of sounds with the added option of assigning different sounds and volume levels to each of the 4 tracks which you can then store in presets. In our view, Rhythm + is perfect as an educational tool. You can easily enter and play the rhythm you want to teach and or learn, without having to use complicated and expensive notation software. An especially useful feature of Rhythm+ for teachers is the ability to store and share exercises in the many levels of folders and sub-folders. Our ambition - to create the simplest, yet most powerful metronome on the market. So whether you are a seasoned pro or a new beginner we believe you will find Rhythm+ a most valuable tool. Enjoy!
