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. (July 2026 Update: Added an "Invert Mode" to perfectly replicate the authentic playing feel of a physical Theremin based on user feedback!) - 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. 3. Authentic Sound Design & High Responsiveness - 4 Basic Waveforms: Choose from Sine, Sawtooth, Triangle, and Square waves. - New Voice Simulation Mode: Switch between the standard LFO Mode and the newly implemented Voice Mode, allowing the synthesizer to articulate the five Japanese vowels ("a", "i", "u", "e", "o") for a human-like vocal expression. - Shepard Tone Mode: Generates the famous auditory illusion of an infinitely ascending or descending scale. - ADSR Envelope: Precisely configure everything from the attack to the release of the sound. - Spatial Expansion: Toggle delay on/off for a richer, deeper sound. - Ultra-Low Latency: Powered by Google's "Oboe" library, ensuring stress-free, instantaneous response to the player's touch. 4. Expandability (BETA Feature) - Bluetooth MIDI Support: Connect to external MIDI devices and play your favorite sound modules with a Theremin-like feel.
