Store description excerpt
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.
