MultiTuneKeys vs Fingerophone

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.

Fingerophone brings the feel of a classic pocket electronic instrument to your iPhone and iPad: slide a finger to play, with no extra hardware to buy. Slide across the compact hex keyboard to play an electronic tone instantly. It is a real monophonic touch synthesizer that makes its own warm, analog-style sound: two slightly detuned oscillators give it a vintage warmth, a resonant low-pass filter rounds off the digital edge, and vibrato adds the familiar wobble. Every control stays within reach while the note is still playing: - Four waveforms (sine, triangle, saw, square), crossfaded as you switch - Vibrato for the classic pocket-synth wobble - Tone to darken or brighten the sound - Drive to push it from clean into gritty - Volume A live oscilloscope draws the actual signal coming out of the synth, so the screen moves with the sound instead of running a canned animation. Scroll the keyboard across several octaves and play quick melodies, sustained drones, and noisy little riffs. Plug in a MIDI keyboard to play the synth, then map its knobs to the controls with MIDI Learn. Everything runs on device, no account and no connection needed. Whether you want to experiment with a pocket synth, explore warm analog-style sounds, or try a finger-played instrument without buying hardware, Fingerophone keeps everything on one focused screen.
