[Demo AU/VST: click "Dowloads" tab] Dig Vox is a hybrid Physical Modelling and Formant synthesizer designed to explore the fascinating space where human vocals meet pure synthesis.

While it leverages advanced physical modelling for a striking degree of realism, it isn't meant to replace snapshot-like, studio-recorded sample libraries.
Dig Vox sits perfectly in the sweet spot between classic vintage formant synths and advanced human singer models. Think of it as a modern spiritual successor to legendary hardware like the Yamaha FS1R and other dedicated vocal synthesis units—engineered specifically to explore that borderline realism where choral voices sound beautifully organic, yet distinctively synthetic.

Whether you want to design haunting, otherworldly pads, classic vintage "vowel" choirs (captivating ahhs, ohhs, and ehhs), exotic world-vocal textures, or quirky, disturbing vocal FX, Dig Vox gives you deep internal modulation to bring your sound to life.

Core Features:

• Accurate Glottis Model: Acts as the primary "vocal folds" oscillator for authentic source generation.
• Physical Vocal Tract Modelling: Simulates the throat, mouth, and tongue for organic vowel articulations and morphing.
• Band-Pass Filters: For classic, warm, analogue-style subtractive and resonant formant modelling.
• Breath Noise Generator: Adds realistic turbulence, air, and whisper characteristics.
• Deep Modulation: 4 LFOs and 2 ADSR envelopes for highly dynamic, evolving patches.
• Expressive Playability: Polyphonic Glide and an independent auto-bend per voice. MIDI CC learn.
• FX Module 1: A 4-voice multiplier/reflection engine for instant stereo width and space.
• FX Module 2: High-quality Delay, Chorus, and Reverb.
• Custom Patch Manager: Easily organise, save, and recall your favourite presets.
• Interactive UI: Hover-over parameter descriptions directly on the GUI for seamless workflow.
