App Tutorial & Features
Our music library is continuously updated with new songs by talented arrangers and shared with the community. Additionally, we have integrated with Musicboxmaniacs.com (MBM), the largest music box community, expanding our library to nearly 50,000 songs. You can freely search, browse, and add songs to your playlists. We also offer official songs for free (30 songs for N20; 15 songs for N40).
No, it doesn’t. You can consider the Muro Box as an “unlocked” or “one-time purchase” music box.
The Muro Box music box plays MIDI files, and the hardware itself has flash memory that can store up to 1,024 songs.
The music box can directly play the last synced offline playlist by simply pressing the knob.
However, we recommend that you create additional playlists to categorize your collection, such as by genre or tempo: sleep, pop, classical, 80s hits, etc. This way, you can play different playlists according to the situation, enhancing your listening experience.
To adjust the songs in the offline playlist. you need to connect the music box to the app, where you can add or remove songs from the offline playlist or drag them to change their orders in the offline playlist.
- Open the Muro Box App.
- Tap the circular profile photo icon in the upper left corner to enter the “Personal Information” page.
- Tap “Notification Settings.”
You can enable or disable each notification according to your needs, including:
– Someone likes your tune
– Someone adds your tune to their collection
– Someone leaves a comment on your tune
– Your tune ranks among the top 5 popular tunes
– Someone follows your playlist
The settings will be saved automatically after completion. You can return at any time to adjust your notification preferences.
- Open the Muro Box App.
- Tap the circular profile photo icon in the upper left corner to enter the “Personal Information” page.
- Tap “Edit Personal Information” to edit your photo, nickname, email, location, website, bio, etc. You can use this area to promote your social media accounts.
- Open the app and tap the “cloud note” icon
at the bottom left to enter the “Music Library.” You can browse popular songs, newly added songs, or explore playlists categorized by themes such as classical, pop, and anime. You can also view the latest MBM tracks, which are synced with the cloud every hour.| - Tap the “magnifying glass” search icon at the top right of the screen, then directly enter the song title, artist, or creator name to quickly find the desired track in the cloud library.
- Next to a song, a “20” marker indicates the 20-note musical scale and model, while a “40” marker indicates the 40-note scale and model.
Arrangement Resources & MIDI Guide
(1) File Format Restriction: Muro Box can only read single-track MIDI files and does not support other formats.
(2) Range Restriction:
N20: Range from C3 to A5, covering the white keys of a piano (excluding black keys).
N40: Range from F2 to A6, excluding F#2, G#2, A#2, and C#3.(Middle C = C3, 261.6 Hz)
(3) Track Length Restriction: Each song can be played for a maximum of 30 minutes as set in the app to prevent insufficient space on the mobile device.
(4)Playback Speed Limit:
At a tempo of BPM = 120, the minimum unit for consecutive single notes is an eighth note.
This means that when using eighth notes, the fastest possible rate for consecutive single notes is 4 beats per second, or 240 beats per minute.
Maximum simultaneous note output:
– N20 model = 7 notes
– N40 model = 10 notes
(Maximum simultaneous note output refers to the highest number of notes that can be struck and played at the same time.)
Q: Why is there a speed limit for note playback?
• Speed Limit: For the same pitch, the maximum playback rate is 4 beats per second (BPM = 240). Faster rhythms will be automatically filtered out.
• Design Rationale: Most music box melodies are gentle and soothing. Since the music box is a simple acoustic instrument, fast-paced arrangements require careful tuning to sound pleasant.
• Physical Constraints: Rapid consecutive notes can cause a “click” noise due to overlapping vibrations. To prevent this, a damper is needed to quickly stop the comb’s vibration.
However, due to the limited internal space of a music box, we cannot use large felt dampers like those found in pianos. Instead, we use a chrome-plated vibration absorber beneath the comb. While this performs better than traditional music boxes, it still doesn’t match the rapid damping effect of a piano.
• Motor Noise: Higher motor speeds increase gear and motor noise. Although the Muro Box motor can run faster, we’ve chosen the current setting to balance performance and sound quality.
The N40’s range is downward compatible with the 40, 30, 20, and 15 notes music boxes, including the Muro Box-N20. So, any compositions created for the N20, whether by you or other customers, can be directly played on the N40.
This article explains how to use the free notation software MuseScore to adjust MIDI files downloaded from the internet into a format that can be played on the Muro Box. It covers steps such as downloading MuseScore, obtaining MIDI files, opening them in the software, adjusting pitch range and octaves, setting instruments and range warnings, and fixing notes that exceed the playable range. The guide is designed to help users with sheet music reading skills edit MIDI files so the music box can perform their favorite songs.

- Keep the microphone at a distance (avoid contact recording): Placing the microphone directly against the wooden casing amplifies motor noise. It is recommended to use an external microphone and maintain an appropriate distance to fully capture the room’s natural reverberation.
For reference, please see the official sound quality comparison video:
https://www.youtube.com/watch?v=y50cW11zRPY - Lightweight equipment and simple post-processing:
Lavalier microphone: Position a small microphone (e.g., Boya Lav) in front of the sound hole, and apply noise reduction plugins (e.g., Brufsi) during post-processing to reduce mechanical noise. Musician Shwan’s test:
https://www.youtube.com/watch?v=bRDALSQmCfo
Handheld recorder: Use a portable recorder (e.g., Zoom H2) for audio capture, then apply noise reduction software and EQ adjustments during post-processing to minimize motor noise. Musician Christophe’s test:

⚠️ Important Reminder:
The hotspot feature on iOS devices tends to turn off automatically very easily. While it is technically possible to use, the experience is poor for most users. Therefore, we do not recommend general users to rely on the iOS hotspot. (The key issue with iOS hotspot sharing is that it often turns off too early—before the music box can connect. Therefore, the key is to keep the hotspot active long enough.)
For the complete step-by-step instructions, please refer directly to the detailed tutorial on iPhone hotspot connection. The process outlined on that page has been tested and confirmed to work. If you have any questions, please contact our customer support: support@tevofy.com.

Due to the complexity of battery transportation safety regulations, we decided from the very beginning of the design process not to include a battery, allowing the music box to be shipped to as many countries as possible.
If you need to use the music box on the go, the N20 Standard, N40 Standard, and N40 Sublime all support USB-C power banks, allowing you to easily take the music box anywhere you go.
Compatible power bank specifications: Minimum of 45W USB-C power supply. Please use a model that supports 15V voltage and at least 3A current (45W 15V/3A).
For example, the following power bank is one of the models we used in internal testing: https://www.mi.com/tw/20000mAh-mi-power-bank-3-pro/specs/
We know that making the music box movement become a DIY module for people to design their own boxes will attract many makers. However, at this early stage, we try to control its performance and stability first for building product’s reputation, so we cannot allow customers to purchase the mechanical part alone. Any mistake in assembling the box may interfere its music playing performance and even damage its hardware.
To avoid potential negative feedback due to inappropriate assembling process, we cannot sell Muro Box without its wooden case. However, after our product is mature enough for developing a DIY module, we will definitely share this news with our fans.
Due to hardware limitations, continuous playback is capped at a maximum of 3 hours. After 3 hours, the playback speed will be reduced to prevent the device from overheating. If you need extended playback, we recommend setting up scheduled playlist playback, with a 30-minute interval between the start times of each playlist to protect the components from excessive wear. You are welcome to review the instructions for setting up scheduled playlist playback.
To ensure optimal sound quality and stability, we do not recommend assembling the mechanical movement yourself.
Minor errors during assembly can affect resonance or damage delicate components. If you are willing to accept the risks and wish to purchase a DIY movement kit, please email your intended use to: support@tevofy.com.
For a perfect hands-on experience, we highly recommend our “DIY Cylinder Assembly Course”!
Purchase the course in our store and book a visit to our Taipei office. You will receive 1-on-1 guidance directly from the Muro Box founders, allowing you to build your own music box and explore our patented design safely.
First, ensure the music box is properly powered on. If you have recently changed your Wi-Fi password, router, or moved the music box to a different location, please re-pair and reconnect the music box in the App. When the App displays “Cannot connect to server,” try tapping the play button or switching tracks to automatically restore the connection, and confirm that your phone’s network connection is stable. If error messages frequently appear, it is usually due to version incompatibility—please update the Muro Box App to the latest version.
If the issue persists, directly tap the gear icon in the bottom-right corner of the Muro Box App toolbar, select “Report a Problem,” and fill out the form. The system will automatically include your device model and serial number to facilitate efficient troubleshooting by our engineers. If the App cannot be opened, you may seek official assistance via the official problem report form or by emailing support@tevofy.com.
Muro Box’s mechanical components, including the comb, solenoids, and gears, are designed for long-term durability and have undergone rigorous endurance testing. Under normal use and proper environmental conditions, there are no components that are expected to fail regularly or require routine replacement.
The lifespan of the following parts may be affected by usage habits and environmental conditions:
- Power adapter and USB-C cable: Please use a USB-C PD power adapter rated at 45W or higher to ensure stable operation of the music box.
- Wooden enclosure: Although it is not a consumable part, natural wood is sensitive to sudden changes in temperature and humidity, which may cause warping. For example, avoid moving the music box directly from a snowy outdoor environment into a warm indoor space, or placing it in an extremely dry environment near a heater.
- To protect the internal components and motor, Muro Box automatically reduces its playback speed after 3 hours of continuous operation. We also provide a 1-year warranty and 3-year repair service. Please do not disassemble the music box yourself.
Regardless of whether you are using the N20 or N40 series, the physical button reset procedure is the same.
- Find a soft cloth to put on a table before you put the Muro Box upside down. This soft cloth should protect the lid of the Muro Box from being scratched by accident.
- Find something tiny and hard like a needle so that you can insert it to the reset hole for resetting the Muro Box to its factory check mode.
【Regarding the location of the reset hole: Please turn the music box over. You will see a small, circular hole (approximately 2 mm in diameter) in the center of the base. This is where the reset button is located. 】 - Push the reset spot with the needle in the unpowered Muro Box. Hold this needle in the reset hole and then connect the power cord of the Muro Box and continue holding this needle for 5 seconds.
- Remove the needle from the reset hole. Wait for the short default melody playing by the Muro Box to tell you the rest step is completed.
- Ensure that Bluetooth is enabled on your phone and that your Muro Box is connected to a stable Wi-Fi network.
- Open the Muro Box App, tap the gear icon in the lower right corner of the toolbar, then select “Music Box Settings” > “Firmware Update.” If a new firmware version is available, the system will display an update prompt.
- Start the upgrade: After tapping “Update Firmware,” the music box will automatically begin downloading and installing the update.
⚠️ Please note:
- Do not disconnect power: During the update process (which typically takes only a few minutes), do not unplug the power cord or turn off the music box, as this may cause damage to the system.
- Maintain network stability: Ensure that the Wi-Fi signal for your music box is stable to avoid download interruptions.
- Retry and report issues: If the update success message does not appear after more than five minutes, unplug and replug the power cord and try updating again. If the issue persists after multiple attempts, please contact us via the problem report feature.
Both the N20 Standard, N40 Standard, and N40 Sublime use USB-PD and can be powered by a portable power bank, allowing you to take your Muro Box wherever you go.
(Note: The N20 Lite uses a traditional DC power supply and does not support this external power bank functionality.)
Compatible power bank specifications: Minimum of 45W USB-C power supply. Please use a model rated for 15V voltage and at least 3A current (45W 15V/3A).
For example, the following power bank model is one we have used in our internal testing: https://www.mi.com/tw/20000mAh-mi-power-bank-3-pro/specs/

Pre-purchase FAQs
N20: The 20-note music box features a diatonic scale, and it does not include semitones (the black keys on a piano). Most pop songs can be transposed to be performed with these 20 notes. It uses a single 20-note comb, producing a crisp, bright sound.
N40: The 40-note scale expands the range and includes semitones (chromatic scale), offering significantly more performance possibilities. It is ideal for songs with larger arrangements or prominent semitones (such as film scores, minor-key songs, jazz, and classical music). The N40 Standard uses two combs (40 notes total), with the same crisp, bright tone as the N20. The N40 Sublime (SLM) features four combs working in harmony. Each note strikes two comb teeth tuned 14 cents apart (80 teeth in total), creating a dense, rich resonance that replicates the luxurious sound of antique music boxes.

N40 Standard – For a Pure and Clean Tone:
It features two 20-note combs for a total of 40 notes, paired with a zinc alloy base and North American hardwood body. The sound is clean, direct, and crisp, ideal for those who prefer transparent, bright timbre with faithful reproduction of the original sound.
N40 Sublime – For Rich and Lush Resonance:
It uses a brass base and heat-treated Acacia wood to produce a warmer tone. The key difference lies in the addition of a set of four combs detuned by 14 cents. During play, this creates a unique layered trembling resonance and extended sustain, resulting in a warm, deep, and emotionally complex timbre that recreates the opulent feel of luxury music boxes.

If you have a custom arrangement, it will be uploaded to the music box before shipping, so you can listen to your selected songs by just plugging in and pressing the knob, without needing the app.
The Muro Box music box plays MIDI files, and the hardware itself has flash memory that can store up to 1,024 songs.
The music box can directly play the last synced offline playlist by simply pressing the knob.
However, we recommend that you create additional playlists to categorize your collection, such as by genre or tempo: sleep, pop, classical, 80s hits, etc. This way, you can play different playlists according to the situation, enhancing your listening experience.
To adjust the songs in the offline playlist. you need to connect the music box to the app, where you can add or remove songs from the offline playlist or drag them to change their orders in the offline playlist.
We currently have demo locations in Taiwan, Hong Kong, Japan, and South Korea where you can try listening and playing with the music box. Please fill out the reservation form in advance or call to book a trial session in case the products are sold out.

- Search for Your Desired Song
Go to the [Muro Box Online Music Library] and search directly by song title or browse the “Popular Songs” section. A mark of 20 indicates the 20-note specification, while a mark of 40 indicates the 40-note specification. - Choose a Preview Mode
Click on a song to enter its playback page, where you can freely switch between two modes:
– Web Mode (Preview): The system digitally plays the melody using the N20 music box’s tone samples, allowing you to quickly verify the melody and arrangement style.
– Live Acoustic Demo Mode: Remotely connect to a physical music box in our Taipei office and hear the authentic sound of the note comb strike in real time! - Select a Model and Listen Immediately
In Live Demo Mode, you can choose between the N20, N40 Standard, or N40 SLM (Sublime) to experience the distinct sound and resonance of each model.
Due to the complexity of battery transportation safety regulations, we decided from the very beginning of the design process not to include a battery, allowing the music box to be shipped to as many countries as possible.
If you need to use the music box on the go, the N20 Standard, N40 Standard, and N40 Sublime all support USB-C power banks, allowing you to easily take the music box anywhere you go.
Compatible power bank specifications: Minimum of 45W USB-C power supply. Please use a model that supports 15V voltage and at least 3A current (45W 15V/3A).
For example, the following power bank is one of the models we used in internal testing: https://www.mi.com/tw/20000mAh-mi-power-bank-3-pro/specs/
Due to hardware limitations, continuous playback is capped at a maximum of 3 hours. After 3 hours, the playback speed will be reduced to prevent the device from overheating. If you need extended playback, we recommend setting up scheduled playlist playback, with a 30-minute interval between the start times of each playlist to protect the components from excessive wear. You are welcome to review the instructions for setting up scheduled playlist playback.

⮕ How to submit a custom arrangement request
Muro Box uses a purely physical mechanical structure to strike the note comb, allowing the metal and wooden box to resonate naturally, producing a crisp tone. Since the sound is generated physically rather than through an electronic speaker, the volume cannot be directly controlled via the APP or a knob. However, you can enjoy the pleasure of fine-tuning the sound by changing the “conductive medium”:
- Increase Volume (Enhance Resonance): Place the music box on a large wooden table, a hollow wooden cabinet, or use the official dedicated resonance box. The large wooden cavity amplifies the volume through physical resonance.
- Decrease Volume (Absorb Vibration): Place a towel, sound-absorbing pad, or similar soft material under the music box. These soft materials absorb part of the physical vibration, reducing sound transmission to the table surface.
Choosing a Muro Box depends primarily on your budget, arrangement needs, and sound quality preferences:
- N20 Series (Ideal for Beginners or Gifting): Features 20 full notes with a crisp timbre. Suitable for those on a budget, for gifting, or for playing general pop music.
- N40 Standard (For Music Creators):Covers nearly 4 octaves (including semitones/black keys) and supports MIDI keyboard input. Best for creators who enjoy arranging and want to faithfully reproduce complex classical pieces or pop songs.
- N40 Sublime (Flagship Collector’s Edition): Utilizes four note combs (80 teeth) playing in coordination, paired with a brass base and a Taiwan acacia wood case. Delivers a rich resonance and sustain, ideal for collectors seeking the ultimate sound quality.
- Common Features: All models support unlimited song playback via the app, offline playlists, and optional laser engraving and custom arrangement services.
