Cube Synth is a groundbreaking new software instrument giving you the power and flexibility of additive synthesis together with easy editing and morphing capabilities. Macro parameters allow you to control this beast with unequalled ease. Intelligent sound morphing capabilities enables you to easily create complex evolving sound scapes, vocal phrases or stunning rhythms simply by choosing up to four sound sources from a predefined set. Then add one of the predefined envelopes and a unique, complex sound preset containing thousands of parameters is created! If you want to dive deeper into the inner secrets of this synthesis monster you can manipulate each parameter individually to get precise control over the sound. A number of high level parameters such as Brightness and Harmonic spread control hundreds of synthesis parameters in a way modeled after the inner workings of natural instruments.
