Cube for iPad is a slightly stripped back version of VirSyn's desktop additive synth of the same name.
Cube's architecture is built around four simultaneous voices, with 512 partials per voice. The Spectral Morphing engine enables controlled morphing between the four voices, with the path of travel drawn into the central XY display, and in-depth adjustment of the 64-stage Volume, X-axis and Y-axis envelopes done in a very detailed trio of editors.
The synth also packs a well-designed, powerful arpeggiator/step sequencer along with seven effects. It's a hugely powerful synth, and although it can get pretty confusing when you dig into its deeper settings, the 400 preset sounds provide a handy jumping off point for new users.
