Proposal: Implementing a Linear Sync Protocol in MuseScore

Introduction

I propose the development of a new linear sync protocol for MuseScore, similar to Avid's Satellite Sync. This protocol would enable near-sample-accurate synchronization between MuseScore and Digital Audio Workstations (DAWs) or other music notation software like Dorico. The goal is to create an open standard that fills a current gap in synchronization capabilities within music production tools.

Background

Avid Satellite Sync is an excellent example of robust synchronization technology. It allows multiple Pro Tools systems and video software like Video Sync to synchronize with high precision. When enabled, it offers a more reliable workflow compared to traditional methods like MIDI Time Code (MTC) and MIDI Machine Control (MMC). Actions such as navigating the timeline, scrubbing, or editing selections are tightly synced across all enabled applications.

While ReWire (now deprecated) previously offered similar functionality, no comparable solution has fully replaced it. Modern audio routing solutions have advanced, but synchronization remains a challenge. Ableton Link is a great protocol for jamming and instant tempo synchronization but isn't designed for syncing edit selections or linear timeline workflows.

The Need for a New Protocol

There's a noticeable gap in the market for an open, easy-to-implement synchronization protocol. Some applications attempt to address this need but are limited by existing technologies. Avid has been reluctant to open Satellite Sync to others, making it difficult for third-party applications to achieve the same level of integration—though exceptions like Flo's Video Sync app exist.

Proposal Details

Key Features of the Proposed Protocol:

• Ease of Setup: The protocol should be straightforward to configure, minimizing technical barriers for users.
• Linear Synchronization: Enable synchronization of multiple tools along a linear timeline, both locally and over a network.
• Open Standard: Adopt an open protocol model (similar to ARA or the DAWproject) to encourage widespread adoption and collaborative improvement.

Benefits to MuseScore

• Enhanced Workflow: Users can seamlessly integrate MuseScore into their existing production setups, improving efficiency.
• Community Leadership: Position MuseScore as a forward-thinking leader in music notation software by contributing to an open standard.
• Interoperability: Foster better collaboration between different software tools, benefiting the wider music production community.

Conclusion

By developing and adopting this open linear sync protocol, MuseScore can fill a significant gap in the current music production landscape. This initiative not only enhances MuseScore's functionality but also sets a new standard for synchronization across music software applications.

I hope the MuseScore development team will consider this proposal and explore the possibilities of implementing such a protocol.
