The Delia Modern Hybrid Poly Synth by Melbourne Instruments

The Melbourne Instruments Delia is a modern hybrid polysynth that merges a digital sound engine with true analog filtering to deliver both flexibility and warmth. Its standout feature is the fully motorized control panel, allowing instant patch recall and dynamic parameter morphing, giving it a uniquely tactile workflow. Designed as a bi-timbral, 12-voice instrument, it enables complex layering, splits, and evolving soundscapes without sacrificing polyphony. Delia combines virtual analog oscillators, wavetable synthesis, and advanced modulation with rich analog ladder filters and overdrive. With features like A/B morphing, a deep modulation matrix, and a built-in sequencer/phrase looper, it bridges the gap between software power and hardware immediacy.
