The Octopus contains one Matrix for Oscillator and Filter Frequency Modulation synthesis and another Matrix for general modulation. The key component for building a sound is the instrument’s 8 oscillators, 2 filters and up to 32 envelopes. These components are all it needs to create anything from classic “old school” FM timbres to complex sounds far beyond those possible with conventional FM synthesis.
The Octopus' 2 Filters permit using the filters as modulation sources; thus they can be used to modulate an oscillator—the sonic possibilities are tremendous.
