General
What is Piano: Soloist?
- A web app that turns sheet music into a piano performance you can watch: the score, falling notes and keyboard move in sync, in 2D/2.5D/3D, with video recording. It runs right in your browser.
Is it free?
- Partly free. The core features are free to use: playing scores, the 400+ piece library, MIDI import, practice tools and video recording. A few extras, such as the high-quality piano and medley mode, come with Pro.
Are there ads?
- Only in two places: on the screen while a score is being converted, and in the optional "watch an ad for one more conversion" after you've used your free conversions. There are no ads anywhere else — not while you play, practice or record, and not in the song list. Pro and Pro-Lite don't see these ads either.
Do I need an account?
- No. There is no sign-up. Your saved scores and settings stay in your browser.
How is it different from Synthesia?
- It runs in the browser, shows the real sheet music next to the falling notes, opens MusicXML/PDF scores as well as MIDI, and records videos. Synthesia is an installed app with more keyboard-learning features.
Which browsers are supported?
- Recent Chrome, Edge, Safari and Firefox. Recording and MIDI keyboards work best in Chrome or Edge on a computer.
Is there a mobile app?
- There is no store app, but the site works on phones and tablets, and you can add it to your home screen. On phones it shows one hand at a time in landscape.
Playing and practice
Can I change the speed?
- Yes, from 0.5× to 1.5×.
Can I practice one hand?
- Yes. You can show only the right or left hand, and the other hand still plays.
Can I jump to a bar or loop a section?
- Yes, use the Bars menu to jump or repeat a range of bars.
Can I connect a MIDI keyboard?
- Yes, in Chrome or Edge on PC and Android (Safari has no Web MIDI). Wait mode pauses until you play the right keys — one piece a day on Basic, unlimited with Pro.
Does it show fingering?
- If the score contains fingering numbers, they appear above the falling notes. You can turn them off.
What views and themes are there?
- 2D, 2.5D and 3D, with themes such as Space, Classic, Christmas and Neon (some are Pro), plus your own background image.
Files and library
Which file types can I open?
- MusicXML (.musicxml, .xml), compressed MusicXML (.mxl), MIDI (.mid, .midi), printed PDF scores and piano recordings.
Where do the pieces come from?
- Public-domain and openly licensed scores (for example CC0 scores from PDMX and other open sources). Each piece page lists its source and license.
How well does PDF conversion work?
- It uses music recognition and works best on clean printed scores. Photos, blurry scans and handwriting are hard, and lead sheets with chord symbols are not a good fit. You can download the result and fix it in MuseScore.
Are my files uploaded?
- MusicXML and MIDI are processed on your device. PDF and recording conversions are sent to a conversion server and deleted as soon as the conversion ends.
How many scores can I save?
- 5 on Basic, unlimited with Pro. They are saved in your browser.
Recording and video
How do I make a video?
- Use Record. Live recording captures the screen as it plays; Render mode draws one frame at a time so even a slow PC makes a smooth video.
Can I make vertical videos for Shorts and Reels?
- Yes. In Render, choose Vertical 9:16.
What quality can I export?
- Basic: 720p with a small watermark. Pro adds 1080p and higher, 60fps and no watermark.
Can I record on iPhone or iPad?
- The site's recording works on computers. On iPhone and iPad, use the built-in screen recording.
Pro and payment
What does Pro include?
- High-quality piano sound, medley mode, 1080p/60fps recording without a watermark, 3D recording, unlimited Wait mode and saved scores, Pro themes and more conversions.
Is it a subscription?
- No. Pro is a one-time purchase that keeps working, including Pro features added later.
Is there a free trial?
- Yes, a 3-day trial without a card. It ends by itself and is never charged.
How do I pay?
- By card, PayPal, Apple Pay or Google Pay. Payments are handled by our reseller, Lemon Squeezy.
Can I get a refund?
- Yes, ask within 14 days of payment for a full refund.
How many devices can I use?
- One license key works on up to 3 devices.
Will sales stop?
- Sales will stop from December 28, but we plan to reopen them later. If you've already bought Pro-Lite or Pro, you can keep using its features.
What is Pro-Lite?
- A $3.99 one-time purchase for people who mainly need conversions: it removes ads and allows 3 PDF conversions a day (up to 20 pages each) and 5 recording conversions a day, with unlimited saved scores. It does not include Pro features such as the high-quality piano.
How many devices can I use Pro-Lite on?
- One Pro-Lite key works on up to 2 devices.
Troubleshooting
There is no sound.
- Check that your device is not muted (on iPhone, the silent switch), then press play again. Browsers only start audio after you tap or click.
Playback stutters.
- Turn on low-graphics mode (2D) or close other tabs. 3D needs more graphics power.
My file will not open.
- Make sure it is MusicXML, MXL, MIDI or PDF. If a MusicXML file fails, re-export it from MuseScore.
