PropheSea is a subtractive vector hybrid synth. It differs from most traditional vector synthesizers in that its waveforms are generated in real-time through subtractive synthesis, rather than being culled from pre-rendered ROM wave selection tables. The real-time waveform generators support a huge variety of internal manipulation.

PropheSea also has multiple LFOs, Additive Harmonic Feedback support, and a global FX section for mutating and sweetening the sound. PropheSea's Dynamic Vector Control allows users to morph between the four waveform generators via their own hand, or through the use of computer automated vector sweeping.
