About

Piano Effect

Features
Read full description

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. A SOUND LIBRARY BY GENRE 41 ready-to-play sounds: gospel, worship, neo soul, jazz, blues, bossa nova, funk, lo-fi, synthwave, 80s, pop, rock, ballad, salsa, cumbia, bachata, merengue, reggaeton, Regional Mexican and more. Plus your scans, saved with song and artist; search them and filter by genre or effect. ROLAND JUNO-DS: MAKE THE KEYBOARD SING With a JUNO-DS the app makes the keyboard itself sound: it loads its patch by number, writes the reverb, echo or chorus into it, or both. When you leave, the keyboard goes back to how it was. 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.
