Particle Music vs MultiTuneKeys

Particle Music is a generative music sandbox where physics makes the song. Drop colored particles into a glass playground, tilt your device — or let auto-motion drive them — and every collision becomes a note. A particle's size picks its pitch on the active scale. Its color is yours. Its voice comes from the layer it lives in. Scatter shaped bumpers across the scene to deflect, accent, detune, filter-sweep, randomize, or echo the sounds that strike them, and a simple still life turns into a composition that keeps unfolding. Four independent layers stack SATB-style, each with its own waveform (morph freely between sine, triangle, square, and saw), subtle pitch drift for choral breath, filter tilt, reverb send, and an octave shift so voices can sit in different registers. What's inside: • Up to 32 particles across 4 voice layers • 6 musical scales plus full Scala (.scl) microtonal import • 6 bumper shapes with spin modes and per-shape audio effects • Per-layer timbre morph, drift, filter, reverb, and octave • Physics you can feel — gyroscope control, edge bounce, collisions, friction, restitution • Preset snapshots to save a configuration and return to it later • Reverb presets from small room to cathedral There's no timeline, no grid, no tutorial telling you what to do. Build a configuration, watch it play, change one thing, watch it play differently. Use it as a quiet background for focus, an ambient companion, or a toy to spark ideas for music made somewhere else. Particle Music is a result of research in the Visual Arts

MultiTuneKeys — Multi-Temperament Piano Keyboard A piano keyboard app you can play with a touch. Enjoy it casually, or switch between 7 different tuning systems to hear the differences. Note: This app does not include piano sound. To make tuning differences clearly audible, it uses 4 simple waveforms (sine, triangle, square, sawtooth — sine and triangle include harmonics control). Whether you want to play casually in equal temperament, or explore historical tunings like Just Intonation or Pythagorean — from a curious starting point to deep musical study, all in one app. ■ 7 Temperaments • Equal Temperament (12-TET) • Just Intonation • Pythagorean • 1/4-comma Meantone • Werckmeister III • Kirnberger III • Custom Tuning — fine-tune each note in 1-cent steps within a ±100 cent range ■ Custom Tuning Editor • 12 vertical sliders aligned with the keyboard • Set a base note and tune intervals by ear • Save up to 3 user presets • Templates: load Just, Pythagorean, Meantone, Werckmeister, or Kirnberger as a starting point • Real-time audio feedback while adjusting (held notes follow slider changes) ■ HOLD (Sustain) — perfect for pitch reference • Sustained notes keep ringing after you lift your finger • Tap a held key again to release just that note • Great for practicing intonation against a chosen tuning while playing your own instrument ■ Anchor Mode • A=440 (default): keep A fixed at the reference pitch — historically authentic, ensemble-friendly • Tonic: keep the tonic at its equal-tempered pitch and let A drift — useful for comparing the same tonic across different tunings ■ Performance Features • Pitch bend wheel with adjustable range (±1 to ±12 semitones) • 4 waveforms: Sine, Triangle, Square, Sawtooth • Harmonics control for Sine and Triangle • Adjustable master volume • Reference pitch: A=415 / 432 / 440 / 441 / 442 / 443 Hz or custom • Haptic feedback on key press • Loudness curve adjustment per waveform ■ For Musicians & Educators • Hear the difference between tuning systems instantly • Perfect for teaching music theory and acoustics • Compare pure intervals in Just Intonation with Equal Temperament • Explore historical temperaments used in Baroque and Renaissance music Banner ads are shown by default.
