XII is an experimental audiovisual work by Liu Hao for iPhone and iPad. Based on twelve-tone composition, it generates music and real-time 3D visuals as a continuously evolving audiovisual performance. Users can define a twelve-tone sequence, while all other musical parameters are generated automatically in real time. Three visual scenes evolve alongside the music, with animation and lighting responding to sound. Users can produce notes by touching the screen, rotate the 3D environment through gestures, and transmit generated MIDI notes to compatible software via Wi-Fi MIDI. XII uses a piano timbre. Its music is not intended to be conventionally tonal or easy-listening. Dissonance and unpredictability are intentional aspects of the work. FEATURES - Twelve-tone sequence configuration - Forward and reverse sequence playback - Real-time automatic music generation - Three evolving 3D visual scenes - Audio-responsive animation and lighting - Interactive note generation through touch - Gesture-controlled 3D rotation - Wi-Fi MIDI output - Background audio support - Piano-based sound generation

Gritopia is a character processor built for adding texture, weight, and attitude to any sound. Rather than simply clipping or saturating, Gritopia layers harmonic coloration, evolving instability, and controlled degradation to create rich, expressive character. From subtle warmth to heavily damaged digital grit, every control interacts to produce movement rather than static distortion. The result is an effect that feels alive, constantly shifting as it reshapes your sound. Perfect for drums, bass, synths, guitars, vocals, and creative sound design. Features • Layered saturation and harmonic coloration • Digital erosion and evolving texture • Dynamic instability and motion • Designed for both subtle enhancement and aggressive destruction Controls Grit – Controls the overall amount of texture and saturation. Tone – Shapes the tonal balance of the processed signal. Fuzz – Adds thick harmonic fuzz and aggressive character. Erode – Introduces digital wear, degradation, and broken texture. Drift – Creates slow, evolving movement. Jitter – Adds fast instability and unpredictable variation. Glue – Blends the processed layers into a cohesive sound. Mix – Balances processed and dry signals.
