Circularity is a new way to explore musical creativity by moving away from the traditional linear synthesizers, and by offering a dynamic two dimensional surface. Circularity does away with cumbersome user interfaces, keeping it to a bare minimum in order to maximize the work area. Notes are generated by circular beacons as they intersect each other’s origins, based on the current radius of the triggered beacon.The user may cycle through the three types of beacons by pressing down(and holding) any beacon. Blue – expands and triggers sounds from blue and red beacons, then disappearsRed – has a fixed radius, can be triggered by any beacon, but can not trigger othersGreen – similar to blue, but offers a steady pulse, can not be triggeredThree layers with different sounds are available and can be cycled through by pressing the rectangular corner buttons.The tempo of each individual layer may be adjusted by pressing the circular corner buttons.Circularity 2 has an organic theme featuring bells, drums and a chorus.The limitations of the free version are:- ad supported- multitouch disabled – a limit of one overlapping sound at a time
