Music Sound Software — HX6 Multi-Engine Synthesizer

Six engines.
One instrument.

HX6 is a hybrid synthesizer where every one of its six oscillator slots can independently run Subtractive, Wavetable, FM, Granular, Additive, or Sampler synthesis — mixed, layered, split across the keyboard, or crossfaded by velocity, all in a single patch.
