Velocity
Dormant developmentopaqueShow more...
The development history shows a complete lack of consistent momentum, with only two releases recorded over a span of more than six years. The latest release in September 2025 provided no release notes, and the previous update dates back to July 2019. Given the extreme inactivity and lack of recent feature development, the app is classified as a zombie project.

Key takeaways for MIDI Scope
Where is it heading?
The diagnostic utility market is consolidating around tools that support multiple protocols like OSC and MIDI. MIDI Scope remains exposed due to its platform-specific stagnation on Android, so the PM must prioritize feature parity to prevent churn to cross-platform rivals.
- The lack of Android updates since 2015 creates a platform parity gap that forces power users toward cross-platform competitors like Protokol.
- High user satisfaction with the core diagnostic utility provides a stable base for implementing requested features like message filtering.
The SWOT
- Raw packet interpretation provides technical barrier to entry
- Free distribution model drives high user satisfaction
- Implementing advanced message filtering resolves primary user complaint
- Adding session export features enables offline analysis
Next best moves
Ship advanced message filtering because users report timing clocks obscure controller data → increase log readability
