## What is Piano Effect?

Put a song near your phone and Piano Effect tells you which keyboards are playing and what effects they use: tremolo, chorus, flanger, phaser, vibrato, Leslie, delay, reverb, drive, compression and detune.

HOW IT WORKS
Tap "Scan" and let the music play for 10, 20 or 30 seconds. When it finishes, the app freezes a verdict: every keyboard it found, its timbre family (electric piano, organ, synth…), its register, and the effect chain with its measured parameters — LFO rate, delay time, reverb tail.

NUMBERS WITH ERROR BARS, NOT GUESSES
Every measurement comes with its margin of error and its confidence level. When something cannot be measured with certainty, the app says so instead of making it up, and shows you what it doubted and why.

PLAY IT YOURSELF
Open the on-screen keyboard and it sounds with the chain that was just measured. Adjust every effect with its knobs, add the ones you want, and save your sounds by name. Turn the phone sideways and three octaves fit. Plug in a MIDI keyboard over USB and play it with your own hands, velocity and sustain pedal included.

HONEST ABOUT ITS LIMITS
The "Limits" tab explains what a phone microphone can and cannot measure over a full mix, so you know when to trust it.

PRIVATE
All the analysis happens on your device. Your audio is never recorded or sent anywhere, and there are no accounts. The microphone only turns on while the scan you asked for is running.

NO ADS WITH PRO
The free version includes advertising, which never appears during a scan. Piano Effect Pro removes it for good with a single payment, and everything that comes with it goes too: the app stops requesting ads, ad consent and tracking permission. Everything else is identical.

## Version history (last 3 releases)

### 1.2 — 2026-09-22

MIDI KEYBOARDS
Plug a MIDI keyboard into your iPhone over USB and play with the effect chain the app just measured. Velocity and the sustain pedal come through, and the polyphony now holds a pedalled chord without cutting notes.

The app shows you what it can actually read from your keyboard, what it can only infer from what you play, and what MIDI simply does not say — the number of keys, the key action or whether a pedal is even plugged in do not travel over the protocol, so the app does not invent them.

NOW IN ENGLISH
The whole interface is translated, note names included: C4 where it used to say do4.

### 1.1 — 2026-09-17

• Si suenan dos o tres teclados a la vez, ahora salen como capas separadas, cada una con su propia cadena de efectos.
• Un colchón de acordes sostenidos ya no se confunde con un arpegio.
• Piano Effect sigue siendo gratis y ahora incluye publicidad, que nunca aparece mientras escaneas. Si prefieres usarla sin anuncios, Piano Effect Pro los quita para siempre con un pago único.

### 1.0 — 2026-09-15
