• The sound is defined by various perceptual attributes such as Periodicity, Brightness, Noisiness, Chaos, etc. These sound characteristics are mapped to two-dimensional (XY) control surfaces. Programming a sound comes down to placing dots on these controllers for getting the desired balance between these characteristics.
• The timbre of the sound can be modulated graphically: you simply draw arrows on the control surfaces indicating the way the sound is altered by the various modulations. UFO's synthesis engine allows hundreds of simultaneous modulations, offering a great deal of expressivity while remaining very easy to program thanks to the graphical representation of the sound.
