Muro Box gives you the freedom of composing your own melodies and allows you to play a lifetime of memories in one mechanical music box. Muro Box has flexible pins on the cylinder to pluck the comb according to your programmed music. There is no capacity limitation on how many melodies you can upload to your music cloud library. Now, you can create as many playlists as you want to play your favorite melodies for different occasions.

We set up the maximum duration/length per song is 30 minutes long to prevent your cell phone overload. Our product uses WIFI instead of bluetooth for connecting app and Muro Box, so you can use our app as a remote controller to play the meaningful music for your family even when you are not at home. What’s more, you can enjoy the whole song performed by a music box without keep turning the switch button.

With our patented cylinder design and the music cloud library, Muro Box can play infinite songs in just one music box. Now, you can choose or compose your own songs and schedule their play time on its mobile app. There is no limitation of how many playlists you can create and no limitation on how many songs you can put into one playlist.

Please note that Muro Box should be connected to the Internet when you update the playlist or upload your own compositions to the app. Otherwise, the songs stored on the offline playlist can be played without Internet connection!

In addition, we have already downloaded more than 30 offline melodies on your Muro Box. Those melodies include well-known classical music, original music, and children’s songs. You can get access to them simply by downloading our app “Muro Box” in App Store or Google Play.

We support both iOS and Android apps. Welcome to download it for free!
Attention: Android needs to be 5.0 or newer version; iOS needs to be 9.0 or newer version.

The procedures for the first-time use are as follows.

  1. Register an account after downloading our Muro Box app.
  2. Pair Muro Box device with your smartphone mobile with WIFI, not Bluetooth.
  3. Choose the music you want to play on Muro Box from the playlists already in the front page or create your own playlists.
  4. When choosing to upload music to create your own playlist, please make sure that your music format is midi and the music range can fit the current 20-note Muro Box: C3-A5 (C4-A6 in American Standard), not including any semitone. If a song contains some notes beyond this range, those notes will be skipped so the music will sound differently.

The songs of Muro Box are stored in the music cloud library. You can edit a melody and play it on our app before sending it Muro Box. There are two things to check before you upload your music to our music cloud library.

(1) The formation of song needs to be MIDI
Please make sure that your file is MIDI. What’s MIDI?

(2) The scale of your song is compatible to Muro Box
According to the Music Instrument Digital Interface(MIDI), the scale of Muro Box is between C3 to A5 (C4-A6 in American standard), so it includes about 2.5 octaves. Please notice that the first generation of 20-note Muro Box uses a diatonic scale (not including sharp and flat). In 2021, we will start to develop a 40-note Muro Box to include more semitones for music professionals. If you are interested in getting a 40-note Muro Box, please subscribe our email from our website. We will keep you updated about our development progress for this advanced model. 

(3) We set up the maximum duration/length per song is 30 minutes long to prevent your cell phone overload.

(4) Muro Box can play as fast as 4 beats per second for the same note, which is consecutive eight notes at BPM 120. The basic unit of notes in Muro Box is eighth note (quaver). Muro Box allows 7 notes to be plucked at the same time as the maximum.

If you need customized music composing service to play on Muro Box, please contact us by email or Facebook.

Muro Box needs electricity to play music. The first generation of Muro Box (for zeczec backers who ordered in 2018) will have a 12V DC power supply in the package, and we will provide the correct power cord to our backers according to their shipping countries. Please notice that Muro Box is a highly-sensitive electronic instrument. To avoid the damage in circuit, please only use the adapter provided by Muro Box.

Due to the restriction of hardware, the first generation of Muro Box can only connect with one device (phone). If you would like to change the device connected with it, please follow the pairing instructions in your app.

We provide 1-year limited warranty, which applies on the body of Muro Box but not include the attachments. The warranty period starts from the first time you pair your Muro Box with a smart phone to activate its service.This warranty covers only defects in material or workmanship under normal use during the warranty period. Please also notice that warranty will be void once you open the body of Muro Box.

We also provide 3-year limited maintenance. Shipping and handling charges may apply except where prohibited by applicable laws. This limited product warranty is valid only where the products are sold by our company or through its authorized retailer or local agent.

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 demange 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.

The following product specifications are for the first generation of Muro Box, which was shipped to our backers from zeczec.com. The product specifications of the newer version of Muro Box, which will be shipped to Indiegogo backers, will be announced later.

Our team has reached a consensus that we will open API in the future, but for now it will be closed API. We want the system get tested from our early customers before release the API to the public. Our system use RESTful api and MQTT, which is standard like most other IoT platforms.

Muro Box can read midi file, but you will need to export your midi file and then upload it to your smart phone or the Internet to get a url for Muro Box app to open it. For the music upload procedure, please check out our tutorial video in the first question of our FAQ page.

We do have many requests about adding MIDI inputs on Muro Box. However we don’t have any plans on this for the coming Indiegogo version of Muro Box, yet. The current Muro Box is positioned as a special gift instead of a musical instrument, and we are planning to fit that gap in the future with an ultimate version that contains a wider scale and more semitones.

So far, we only designed one style of case for Muro Box for our Indiegogo campaign. We will provide two different colors (oak color versus maple wood color) as shown in the following picture.

Our design concept is to present the beauty of mechanical movement as the key attraction of music box. Welcome to watch this video to better understand our current design. In the future, we welcome other designers to create models with decoration or moving figures to reflect different tastes in different countries.
