Muro Box-N40 Standard

Turn Your Programmable Music Box into a Musical Instrument

The Music Box That Plays Your Own Music

Do you love the sound of a music box and wish it could play your compositions like a piano? Now, with the N40 Standard version of the music box, your dream can easily come true! By connecting a MIDI keyboard and laptop through the MIDI input port, the music box can perform your compositions in real time.

Allow us to proudly introduce the world’s first app-controlled music box, “Muro Box,” designed and manufactured in Taiwan. Its name is derived from the abbreviation of Music Robot in a Box.

Increase Music Range to 40 Notes

The N40 can use 40 notes:

F2-C6 (excluding F#2, G#2, A#2, and C#3; Middle C = C3 = 261.6 Hz)

To understand why we chose to exclude these four semitones, please refer to this Muro Box-N40 update #8.
When users want to cover other people’s songs, the current N40 scale range can restore the original songs’ features easily. N40 also gives you more freedom to create your own melodies and chords.

Easily Compatible with Various MIDI Devices

Allow us to proudly introduce the world’s first app-controlled music box, “Muro Box,” designed and manufactured in Taiwan. Its name is derived from the abbreviation of Music Robot in a Box.

Both N40 music box models come with the DIN 5 MIDI input and USB-C MIDI input (Host/Device Mode), allowing you to connect the Muro Box-N40 to any MIDI devices.

For detailed instructions on using MIDI external devices, please refer to this tutorial page.

※Please note that the button on the back is the switch for the MIDI device, “NOT” the power switch for the music box! The Muro Box music box is powered on as soon as it is plugged in. Simply keep it plugged in to maintain the power-on state; there is no “off” mode. If you really wish to turn it off to save energy, please unplug it directly. Plugging in the Muro Box is equivalent to turning on the power.

One Music Box Play All of Your Favorites: Set the length and number of songs as you wish!

With the exclusive Muro Box app, you can search for songs, edit playlists, and create new melodies to send directly to the music box for live performance. Finally, your dream of playing a complete custom repertoire on a music box can come true!

The Muro Box-N40 music box expands its range to 40 notes, including black-key semitones, letting you store all your favorite theme songs of cherished memories!

More Compatible Free Melodies Export from Music Box Maniacs

Support more tracks to be exported from Music Box Maniacs ( MBM ) to Muro Box-N40 for free!

The rich music collection made by global music box fans can be imported to your Muro Box App simply by scanning the QR code of the melody you like!

N40 Widens Music Range to Break the Limitation for Music Arrangement

The N40 music range covers 40 notes from F2 to C6. (Middle C = C3 = 261.6 Hz)
The music range spans nearly 4 octaves, providing you with more varieties in arranging your own accompaniment and melody.

▲The above video is a simulation of the tone and not an actual recording of the N40 music box’s sound. The focus of this video is to demonstrate how the expansion of the N40’s range enhances the variability in arrangement techniques.

The Secret to Beautiful Sound: Our Dedication to Material and Craftsmanship

The comb, metal base, and wooden box body complement each other, and each is indispensable. Let’s take a look at the development journey of each component to understand the key technologies and design insights that allow the music box to produce a lingering resonance, just like a musical instrument.

Complete Music Range with 40 Notes

Using 2 combs (vibration plates) to cover notes in a chromatic scale to truly satisfy musician’s composition needs and faithfully representing meaningful songs in your memories.

We utilized modular design to extend the well-refined 20-note comb to build the N40 music box based on the foundation of our existing product: Muro Box-N20. The comb of the previous N20 model has undergone over 1,000 hours of wear and stress testing, ensuring its quality and reliability. If you are interested in learning more about the development process of our comb, please refer to this blog post.

Exclusive Ｂrass Tuning Weight Design

The reason for using brass is because we aim to utilize a lead-free process, which rules out the use of conventional lead blocks. Brass, being a material with a higher density, is the most common alternative and is readily available with stable processing properties.

We have proposed a new method of securing the brass blocks using a dovetail joint. This involves drilling holes at the front end of the comb teeth, allowing the brass blocks to be inserted and wedged directly onto the teeth.

>>Learn More about the Design Process of the Comb

Zinc Alloy Base

The traditional music box base is crafted from zinc alloy to produce warm and mellow sounds. Welcome to read this article to learn about the manufacturing process of the zinc alloy base.

Resonance Box: Enhancing Volume and Sustain

The N40 series packaging is designed with a different approach, combining the functions of a shipping box and a resonance box.

The impact of the wood on sound quality was our primary consideration. After extensive visits and procurement, evaluating sources and manufacturing processes, and conducting sound quality experiments with resonance boxes made from different woods.

Customers' Comments about N40 Standard

Muro Box is my dream instrument!

Shawn

Hi, I’m Shawn from Lullatone. My wife Yoshimi and I make music as Lullatone. We’ve released a ton of albums and also recorded songs for films and videos.
I’m a big fan of the Muro Box – the amazing electro-acoustic mechanical music box that lets you play your own melodies on its tines. You can connect MIDI keyboards, use their app or even send the notes to play from your DAW (like Ableton, etc). The new Resonance Box makes your music box melodies louder, deeper and richer.

Here, I’m controlling the plucking of the music box’s tines with the OP-1 Field’s keyboard by MIDI over USB-C, while sometimes adding in soft sine tone synth sounds coming out of the OP-1 at the same time. Soft sine tones and music boxes have been the Lullatone dream team since the early 2000s : )

What a beauty and what a sound!

Joeri

I’m Joeri from the Netherlands; I am also a member of the Dutch Pianola Association. Being an interested person of inventions that use technology and innovative energy to make the world better, I was becoming one of the earliest customers of the N20.

A few years later, when the N40 crowdfunding campaign was launched in October 2023, I immediately decided to support it.

The N20 enriched me to play with an automatic music box in which you can play more different pieces of music with a beauty of sound. I like to help with interesting developments. And with the N40 you get a larger range of (chromatic) tones.

My expectations (and they are even more than that I hoped for) of the N40: a more complete beauty of instrument with a lot of possibilities.

The music they play is beautiful and fills the entire room. It’s not a soft tinkling toy, but a true instrument.

The music they play is beautiful and fills the entire room. It's not a soft tinkling toy, but a true instrument.

Hanneke

Since childhood, I have been deeply enamored with music boxes, especially the punched paper tape type. Today, I’ve transcribed the music from these paper tapes into the song library of the Muro Box App.

I initially purchased the N20, which impressed me not only with its elegant design and high-quality sound but also with its song-switching feature. So when N40 was released, I immediately pre-ordered both the Sublime and Standard models.

The N40 Sublime, with its special resonator, plays classical pieces with a majestic reverberation effect, reminiscent of the rich sounds from my grandparents’ antique music box. The N40 Standard, on the other hand, has a pure tone quality that’s ideal for reproducing serene melodies, such as those found in traditional nursery rhymes.

The standard N40 version leans more towards a simple music box sound, and suits those songs better.

Muro Box App Functions

No matter which model of Muro Box you have, you can enjoy the same composing functions and music cloud library.

Start Playing Your Favorites by Pressing the Knob!

Adding songs to the “offline playlist” is similar to copying and pasting files from your cloud drive folder to a local folder at your desktop.

All of the family members who have paired with the same Muro Box can edit an exclusive offline playlist for this music box by adding or removing songs and adjusting the order.

Huge Music Box Melody Collection

Muro Box App supports searching tracks from Music Box Maniacs (MBM) for free! The rich music collection made by global music box fans can be found easily in our app.

In our app, you can easily explore a diverse collection of music box melodies created and shared by music box enthusiasts from around the world. New songs are added daily, and you’re welcome to add them to your personal playlist anytime. With a Wi-Fi connection, you can transfer your app playlist to the Muro Box for playback.
Whether you choose the N40 or N20 model, you’ll enjoy the same app library resources, with full access to select and save your favorite songs!

How many songs will be preloaded in the music box?

If you haven’t ordered our customized music arrangement service, the music box will include 15 official complimentary tracks in the offline playlist. There will be famous classical music and children’s songs as well as some original music.

If you have ordered our music arrangement service, the melody you requested will be added to the offline playlist, while the initial 15 complimentary tracks we made will be stored in the online playlist for you. This allows you to directly play your customized melody by pressing the knob after you or the gift receiver unboxes the product. Your customized melody playing from the music box will touch his/her heart with a surprise!

Note: Search “N40 Official List” in the Muro Box App, and you will find the 15 complimentary tracks we provide.

Create Your One-of-a-Kind Music Box with Our Custom Services

Free Customized Engraving Service

Add-on Service: Customized Arrangements / Upload Playlist for You

Musical Arrangement

Lack of music arranging skills? No problem. With Muro Box’s experienced music arrangers and a complete 40-note range, your beloved songs will be faithfully represented in the classic music box.

If you prefer the entire song, please contact us to get a quote. After the arrangement is complete, we will provide a MP3 file for preview and offer two opportunities for revisions. After you approve it, the song will be uploaded to the music box before shipping, so you or the recipient can hear the customized song by simply powering on and pressing the knob.

Create My Playlist

(Only Public Songs in Muro Box App Library Are Applicable)

By purchasing this service, we will preset your exclusive playlist before the music box is shipped, so that when you press the button, the music box will instantly play ten carefully selected songs from our app’s public library. Additionally, you can customize the playlist’s cover and name, creating a personalized themed playlist (e.g., “Our Favorite Memories”), adding a surprise and conveying your feelings when giving the gift.

*This service is designed to enhance customization options for gift-giving. If not purchased, you can still use the app to freely choose and add songs from the public library to your collection after receiving the music box.

Add-On Option: Black Color Painted on the Wooden Box

If you prefer a darker color compared to the natural wood tone, we offer an upgrade service. You can choose to have the music box’s natural maple wood box upgraded to a sleek, matte black lacquer finish. The smooth, refined black paint will replace the original wood grain, matching the zinc alloy base and stainless steel accents, showcasing your unique taste.

Clever Resonance Box Design

We visited many manufacturers in Taiwan to study the characteristics and limitations of different materials to create a melodious tone for the music box. We finalized the design of the N40 music box’s wooden case by referencing instruments like guitars and kalimbas, and incorporating customer feedback.

Duel Functions: Amplification and Storage

The packaging wooden box for the N40 music box transforms into a dedicated resonance box once assembled. When used together with the music box, it enhances the richness and resonance of the sound, making the music box’s tail notes more vibrant and full!
Unlike speakers, the sound mechanism of a music box cannot be controlled by a volume knob. The volume can only be reduced by using softer materials like cushioning fabric or silicone pads to dampen the sound waves transmitted through the wooden box to the surface. To amplify the volume and extend the resonance effect, the Muro Box-N40 dedicated resonance box is required.

We have designed a dedicated resonance box for the N40, available in the following four styles:
1. Millettia Laurentii (Chicken Wing Wood)
2. Pinewood painted in black walnut color
3. Pinewood coated with a clear protective finish
4. Unfinished pinewood
(As shown in the image, from left to right)

Customers who purchase the N40 music box will receive a complimentary unfinished pinewood resonance box, which also serves as the product’s packaging box. If you choose to upgrade to another version of resonance box, such as “Pinewood with Clear Coating,” “Pinewood with Black Walnut Coating,” or “Millettia Laurentii,” we will replace the default unfinished pinewood resonance box with the upgraded version you selected when shipping your order.

The harder the wood used to make the resonance box, the clearer and more beautiful the reverb effect. Pinewood is the softest wood option, while Millettia laurentii (chicken wing wood) has a higher hardness.

The pinewood resonance box is available in two color options: natural pinewood with a clear protective coating and pinewood with a black walnut wood-colored finish.

Come and listen!
Experience the performance effects brought by resonance boxes made of different materials.

We selected the classic piece “The Old Clock” to help you compare the sound quality differences using a familiar melody. The recording was done in the same setup environment with various combinations of different models and resonance boxes, allowing you to directly compare and find your favorite sound combination!

(1) Muro Box-N40 Sublime + Millettia Laurentii (Chicken Wing Wood) Resonance Box Performance of The Old Clock
(2) Muro Box-N40 Sublime + Pinewood Resonance Box Performance of The Old Clock
(3) Muro Box-N40 Standard Model + Pinewood Resonance Box Performance of The Old Clock
(4) Muro Box-N40 Standard Model + Millettia Laurentii (Chicken Wing Wood) Resonance Box Performance of The Old Clock

The Resonance Box of the N40 also Serves as the Product Packaging Box

The items shipped together are as follows: the N40 music box, the scratch protection cover for the music box lid, the music box’s outer box which also serves as the resonance box, the user manual, and the brand introduction card.

Box A: Power cord, USB-C adapter.
Box B: Sound Post x1, shock absorber x4, metal pad x4.

Note:
The resonance box also serves as the outer box of the music box. When shipping, we will place the music box inside the resonance box. Therefore, when purchasing an N40 music box, you will need to choose a resonance box for it. If you do not wish to upgrade or purchase a different style of resonance box, we will ship your N40 music box with the default unpainted pine wood resonance box at no extra charge.

This is an unboxing video we made using the N40 Sublime music box paired with the unpainted pinewood resonance box. It provides a preview of the packaging and accessories you will receive with the N40 Standard music box, which are identical to those of the N40 Sublime version.

The New feature will Open Your Eyes!

No need for an internet connection—just plug in a USB flash drive and start playing.

Any MIDI file that fits within the music box’s note range can be placed on a USB flash drive and inserted into the Muro Box’s MIDI input port. The music box will read the file and play it directly! This allows those who cannot connect to the internet or are not familiar with using the app to easily change songs on the music box.

Note 1: The maximum number of tracks on the USB flash drive is 100. Only single-track MIDI files can be read.
Note 2: MIDI file formats must be within the Muro Box’s note range:

N20: C3-A5 (excluding black keys)
N40: F2-C6 (excluding F#2, G#2, A#2, B#2)
Middle C = C3 = 261.6 Hz)

Where to find MIDI files?
The best place to find music files is within the community dedicated to arranging for music boxes. For guidance, please refer to: How to Download Music from the Music Box Maniacs (MBM) Website.
Bonus: USB-Type C Adapter Included
A USB-Type C adapter will be included with your order, making it easier to connect a USB flash drive or other MIDI devices to your Muro Box music box.

Supports Portable Power Banks Easy to Carry

Both the N20 Standard and N40 series use USB-PD and can be powered by a portable power bank, allowing you to take your Muro Box wherever you go!

Compatible power bank specifications: Minimum of 30W USB-C power supply. Please use a model that supports 15V voltage and at least 2A current (such as 30W 15V/2A or 45W 15V/3A).

Please refer to the following power bank models used in our internal testing: https://www.mi.com/tw/20000mAh-mi-power-bank-3-pro/specs/

Preset Playback Time: Transform the Music Box into a Charming Alarm Clock

With the Muro Box exclusive app, you can easily set multiple timers, allowing the music box to become part of every important moment in your life, adding a touch of elegance and surprise to your daily routine!

Many customers choose to use the beautiful melodies of the music box as an alarm to wake them in the morning. Some stores use the timer function to make the music box a thoughtful timekeeper, while romantic users plan special surprises for anniversaries—playing specific songs at specific moments, infusing precious moments with deeper emotions and memories.

How many songs are available in the app’s music library?

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).

Can I listen to music without connecting to the app?

Not familiar with connecting to the app? No worries! The music box comes pre-loaded with the official playlist (30 songs for N20; 15 songs for N40). Once plugged in, simply press the knob to play the default playlist. 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.

How much storage space is available for songs in the music box? How many songs can be saved in the offline playlist?

The Muro Box music box plays MIDI files, and the hardware itself has flash memory that can store around 2,000 songs.

Thus, the maximum number of songs that can be stored in the offline playlist on the app is approximately 2,000. 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.

How many offline songs can be set on the music box?

Songs placed in the offline playlist can be played directly by pressing the knob on the music box. The Muro Box music box reads MIDI files for playback and has built-in flash memory that can store up to 100 songs.

To adjust the songs, connect the music box to the app, where you can add or remove songs from the offline playlist, or drag to reorder them.

Range and tempo limitations for music box arrangements

(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 Restriction: At a BPM of 120, continuous single notes can be played with a minimum unit of eighth notes; thus, the fastest continuous single note can be 120 notes per minute. The maximum number of simultaneous notes = 10 (up to 10 notes can be played simultaneously).

Can I use the compositions I created for the N20 to be played on the N40?

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.

How to estimate import duties when shipping from Taiwan to overseas?

We will use the website provided by DHL to estimate the local import duties based on the product price. If you need assistance with the estimation, please email us at support@tevofy.com.

Why doesn’t the music box have a built-in battery?

Due to the complex safety regulations involved in transporting batteries, 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/ N40 Sublime models all support using USB-C power banks, making it easy to take the music box with you anywhere.

The Specifications of the Power Bank forMuro Box-N20 Standard / N40 Standard / N40 Sublime Music Boxes

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!

Compatible power bank specifications: Minimum of 30W USB-C power supply. Please use a model that supports 15V voltage and at least 2A current (such as 30W 15V/2A or 45W 15V/3A).
