Inclination Theremin

Turn Your Smartphone into a "Breathing" Instrument. An Intuitive Sensor Synthesizer.

[Concept: Beyond Tapping – Unleash True Expressiveness]
Have you ever felt that simply tapping a smartphone screen makes it hard to convey delicate musical nuances?
This app was developed to transform your smartphone's highly accurate tilt sensors into a true instrument's expressive power.

Control the pitch by the tilt angle of your phone, and seamlessly manipulate the volume and vibrato with your tap position. It's a unique playing experience, much like a Theremin. Your fingertips and the movement of your device become one, allowing you to play melodies more intuitively than ever before.

[Key Features]

1. Multi-Dimensional Expression via Sensors
- Pitch: Changes seamlessly based on the smartphone's tilt angle.
- Volume: Express dynamics via the Y-axis (up/down) of your tap position.
- Vibrato: Control sound modulation via the X-axis (left/right) of your tap position.
- XY Pad: Real-time control of the cutoff filter and resonance using the on-screen pad.

2. Powerful Scale Features Based on Music Theory
- 30+ Scales & Arpeggios: From classical to jazz. With advanced scale quantization, you never have to worry about hitting the wrong note.
- Custom Scales: Create your own original scales.
- Instant Scale Switching Mode: Switch scales instantly with a single button. Effortlessly express chord progressions based on functional harmony or perform dramatic modal interchanges.
