What it is
Violin2Notes uses AI to turn recordings of violin, viola, cello, and double bass into editable scores and music files. It can work with string parts even when other instruments are present. Users can upload audio, paste a YouTube link, or record in the app; supported upload formats include MP3, WAV, MP4, MIDI, and FLAC. An editor lets users adjust notes, timing, and layout before exporting PDF sheet music, quantized or unquantized MIDI, or MusicXML. Piano Roll mode provides a visual way to view and play along with a transcription. Free demos can be repeated, but each covers only the first 20 seconds of audio, a video, or an in-app recording and provides a PDF preview. Pro includes 50 full transcriptions per month, each up to 15 minutes. It costs $14.99 a month, or $6.24 a year with annual billing, shown as an equivalent monthly cost. The service is available on web, iOS, and Android, and the maker says transcriptions sync across those platforms. The maker says clear recordings focused on strings produce the best results; corrections can be made in the editor.

Violin2Notes in depth
Read the full write-up
Violin2Notes is a transcription tool for violin, viola, cello and double bass recordings, including recordings with other instruments. It is best suited to players and arrangers who want to turn audio into editable scores; choose it for the editing and export workflow, not for full-length transcription at no cost.
Overview
You can begin with an uploaded file, a YouTube link or a recording made in the app. Violin2Notes produces notation and MIDI, then lets you refine notes, timing and layout before export. That combination is useful when the goal is a playable, adjustable score rather than a transcription to inspect and discard.
Source quality affects how much correction is needed: results work best with clear recordings focused on strings. The editor helps address errors, but it does not remove the work of reviewing a transcription. Audio is capped at 15 minutes per transcription.
Key features
Flexible inputs: Upload MP3, WAV, MP4, MIDI or FLAC, paste a YouTube link, or record in the app. That covers existing material and new takes without requiring a single recording workflow.
Score editing and exports: Adjust notes, timing and layout, then export PDF sheet music, quantized or unquantized MIDI, or MusicXML. The choice is valuable for moving between a readable score and formats intended for further music work; the maker says exports are compatible with major notation software and DAWs.
Piano Roll: View and play along with a transcription in an interactive visual format. This gives users another way to inspect the result alongside conventional notation.
Chord detection: Chord detection is supported, but tablature output is not. Players who specifically need tab should look elsewhere.
Cross-device syncing: Web and mobile apps sync transcriptions automatically, which helps when moving between devices.
Pricing
The free plan costs nothing and allows unlimited demos, but each demo transcribes only the first 20 seconds and provides a PDF preview. It is a way to check short passages, not to complete a full score.
Violin2Notes Pro (annual) costs $6.24 a year, shown as an equivalent monthly cost and billed annually. It includes 50 full transcriptions per month, up to 15 minutes each, and unlimited demos. Pro monthly costs $14.99 a month with the same quota and length limit. The annual option suits users willing to commit to annual billing; monthly is the more flexible choice for shorter-term use. Either paid plan is necessary for full transcriptions, and the 50-per-month cap matters to frequent users.
Platforms
Violin2Notes runs on web, iOS and Android. The maker says transcriptions sync automatically between its web and mobile apps. Its privacy policy says the website is hosted in an EU data center and uses SSL/TLS encryption for transmitted data.
Who it's for
Choose Violin2Notes if you play or arrange strings and want to create, edit or arrange a playable score from a recording, including music without existing sheet music. It is less suitable for users who need tablature, routinely work from unclear or dense recordings, or need more than 50 full transcriptions a month.
Pros and cons
Pro: Input options include uploads, YouTube links and in-app recording, so the workflow accommodates different source material.
Pro: Editing plus PDF, MIDI and MusicXML exports gives users a route from transcription to a refined score or compatible music file.
Pro: Unlimited short demos make repeated checks possible before paying.
Con: Free demos stop at 20 seconds and provide a PDF preview, limiting their usefulness for completing a piece.
Con: Paid plans cap full transcriptions at 50 per month and 15 minutes each.
Con: Accuracy works best with clear, string-focused recordings, and no tablature output is available.
Alternatives
Audio-to-MIDI converters and Music Transcription Software are useful starting points for comparing broader categories. For more specific alternatives:
AnthemScore may suit users seeking a desktop option, since it runs on Linux, macOS and Windows as well as web; its free trial allows full songs up to six minutes before switching to unlimited 30-second clips.
DrumConvert is the alternative to consider for drum conversion, with free 30-second conversions and PDF, MIDI and MusicXML export.
Klangio Transcription Studio offers the same web, iOS and Android availability and unlimited free demos up to 20 seconds, making it a close option for users comparing Klangio’s transcription apps.
Mirelo is an option for users seeking an API or desktop availability across macOS and Windows, as well as web access.
MuScriptor offers a free hosted demo and MIT-licensed code for users who prioritize open-source access; its model weights are CC BY-NC 4.0 non-commercial.
NoteFusion may fit a short trial of use: its free plan allows five transcriptions per account in total, and its one-month Pro access does not renew automatically.
Piano2Notes is the relevant alternative for piano recordings; its free demo is also limited to the first 20 seconds and its Pro plan costs $14.99 a month.
PianoConvert is another piano-focused option, with a 30-second free conversion limit and score edits included in its free plan.
Verdict
Violin2Notes is a sensible fit for string players and arrangers who need an editable score from audio and value several export formats across web and mobile. Its strongest reason to choose it is the path from transcription through correction to export. Look elsewhere if a 20-second preview is not enough to judge it and you do not want a paid plan, or if you need tablature or higher monthly volume.
Verdict
Violin2Notes combines string transcription with editing and several export formats across web and mobile. The free demo is brief, while Pro has monthly transcription and length limits.
