12-Voice Motorized Hybrid Analog/Wavetable Polyphonic Synthesizer

The Melbourne Instruments NINA is a 12-voice, 4-part multitimbral hybrid synthesizer distinguished by its tactile, high-resolution motorized control panel. Combining two discrete analog VCOs, a 96kHz/24-bit digital wavetable oscillator, a classic 4-pole transistor ladder filter, and a proprietary four-quadrant stereo VCA, NINA merges vintage analog warmth with deep digital sound design and instant physical parameter recall.

NINA eliminates parameter jumps through motorized rotary knobs featuring contactless optical sensing with 16,000 steps of resolution per rotation. When loading presets, switching multitimbral layers, or sweeping A/B Patch Morphing, every physical knob snaps or glides into position in real time. Users can customize knob resistance, tactile detents, and zero-points directly from the interface, while an onboard oscilloscope provides immediate visual feedback.

Each of NINA’s 12 voices pairs two analog VCOs (morphable between triangle and sawtooth, crossfadeable to pulse with PWM, VCO 1 sub-octave, and VCO 2 hard sync) with a 96kHz/24-bit wavetable oscillator that supports user-loaded WaveEdit wavetables and can double as an audio-rate LFO. Subsequent firmware expansions have further broadened the engine with 64 noise types and all 45 digital macro oscillator models from Mutable Instruments Braids running across all 12 voices. The oscillator mix passes through an overdrivable 4-pole transistor ladder lowpass filter into a four-quadrant stereo VCA capable of 360-degree infinite stereo panning and dynamic polyphonic spin schemes.

Built on a Raspberry Pi 4 running Elk Audio OS, NINA offers up to four independent multitimbral layers (with individual MIDI channels, octave offsets, keyboard splits, and MPE support), an unlimited-bus modulation matrix (16 sources and 27 destinations), and a built-in arpeggiator alongside a 4-track, 64-step polyphonic sequencer with per-step parameter locks. Three 96kHz/24-bit VST3 effect slots can run in series or parallel at either the global patch level or on individual layers.
