The synth features two main oscillators and one sub-oscillator. Each main oscillator includes a "Fat" knob that stacks up to seven copies of the oscillator, detuning them to create immediate richness. Combined with unison mode, DUNE 1 can generate up to 120 oscillators per note .
It includes 18 filter combinations, ranging from classic low-pass and high-pass to dual-filter modes and filters with integrated distortion or bitcrushing. The modulation matrix, though powerful with up to 24 slots in the full version, is designed to be accessible only when needed to maintain a fast workflow.
A built-in effects rack provides distortion, phaser, chorus, delay, and reverb. Its arpeggiator supports custom programming and was highly regarded for trance and progressive music production. The Legacy of DUNE 1
