Yes. Absolutely.

From the very beginning, Muro Box was designed with the belief that a music box should be able to last for generations. To avoid the common risk of vendor lock-in associated with smart devices, Muro Box is built on open hardware architecture and standard communication protocols.

Even in the most extreme scenario—no official server, no Internet connection, and no App—your Muro Box remains a fully functional smart music box. You can continue using it and changing its songs through the following two completely cloud-independent methods:

1. Offline Playback (Built-in Memory & USB Drive Support)
   
   Muro Box features built-in non-volatile memory. Any offline playlists synchronized from the App are stored directly inside the device. Even without an Internet connection or the App, simply connect the power and press the control knob to play the locally stored playlist.
   
   In addition, Muro Box supports direct playback from a USB flash drive. We designed this feature for users who prefer a simple, familiar way to update their offline songs without using the App.
   
   Simply:
   
   
   
   • Prepare a USB flash drive formatted as FAT32.
     
     
     
   • Copy your Standard MIDI files (.mid) into the root directory of the USB drive.
     
     
     
   • Insert the USB drive into the USB-C port on the back of the music box. Muro Box will automatically import the files into its offline playlist.
     
     
     This means that even without the App, you can freely update the songs stored in your music box for its entire lifetime.
     
     
     
2. Standard MIDI Interface (Lifetime Hardware Compatibility)
   
   At its core, Muro Box is a MIDI playback device built around a real mechanical comb. It supports the industry-standard MIDI protocol via USB-C or Bluetooth BLE, allowing it to operate independently of our App or cloud-based music library.
   
   
   • Connect to a computer or mobile device
     
     You can use virtually any Digital Audio Workstation (DAW), including GarageBand, Logic Pro, Cubase, or Ableton Live, as well as third-party or open-source MIDI playback software, to send MIDI data directly to Muro Box for real-time performance.
     
     
   • Connect to external MIDI instruments
     
     You can also connect Muro Box directly to MIDI keyboards, digital pianos, or other MIDI-compatible hardware. Whatever you play on the controller will be performed instantly by the music box.
     
     

Even if the official App is no longer maintained in the future, engineers and makers around the world can continue controlling Muro Box using existing technical documentation with tools such as Python, Raspberry Pi, or Arduino, or even develop their own third-party control software. The product’s lifespan is not limited to our software—it can continue evolving with the community.

• We fully understand concerns about the longevity and long-term reliability of smart devices. That’s why Muro Box is designed with a decentralized architecture. The cloud service and App are provided for convenience—not as a requirement. When you purchase a Muro Box, you own a fully programmable mechanical musical instrument that remains under your control.
