NEOkILLER III is a Virtual Analogue synthesizer designed to deliver rich and dynamic soundscapes. It features two quad oscillators that generate a wide range of tones, complemented by a white noise oscillator for added texture. The synth includes a unison mode capable of stacking up to seven voices, allowing for thick and powerful sounds. Oscillator cross modulation provides complex frequency modulation capabilities, enhancing the sonic palette.

The sound shaping section boasts state-variable filters with selectable modes including low-pass, high-pass, band-pass, and band-reject, with low-pass filters available in both 12dB and 24dB per octave slopes. Modulation options are extensive, featuring six-stage envelopes that support looping and adjustable interpolation modes for precise control. A tempo-synced low-frequency oscillator (LFO) and a randomator expand modulation possibilities, enabling evolving and rhythmic effects.

NEOkILLER III also incorporates two distinct overdrive stages, one applied per voice before the filter and another after the VCA stage, adding warmth and grit to the sound. The dedicated ADSR envelope for the VCA stage ensures clear dynamic articulation, while a built-in gate effect provides additional rhythmic shaping. These features combine to make NEOkILLER III a powerful synth capable of producing a wide array of tones from subtle textures to aggressive leads.
