MIDI-Probe
By Michael Hitz
MIDI-Probe is a free MIDI diagnostic utility for iPhone and iPad that monitors and sends MIDI commands across USB, Bluetooth, and network protocols.
The App DNA
What makes this app unique?
It removes the cognitive friction of debugging complex MIDI signal chains by providing a transparent, timestamped view of exactly which messages reach a target device.
For Music producers, hardware developers, and live performers requiring MIDI routing verification.
What does it look like?
Key features
Detects USB, Bluetooth, and RTP network MIDI devices with serial and transport details.
Monitors inbound MIDI traffic with command-type filtering.
Verifies MSB/LSB pair transmission for high-resolution parameter changes.
How much does it cost?
MIDI-Probe functions as a community-driven utility with no monetization gates, prioritizing accessibility for technical users.

Competitive landscape for MIDI-Probe
How's the Music market?
MIDI-Probe occupies a niche utility space in the Music category, currently holding a 5-star rating from a single user. The lack of recent updates (241 days) positions it as a static tool rather than an active competitor in the MIDI diagnostic market.

Key takeaways for MIDI-Probe
Where is it heading?
The market for specialized MIDI utilities remains stable but niche, with little pressure for rapid feature iteration. MIDI-Probe's current maintenance-only posture means it will likely remain a static tool, which risks obsolescence if iOS MIDI APIs change significantly in future versions.
- The 241-day release gap suggests the developer has moved to a maintenance-only posture, limiting future feature expansion.
- The lack of user feedback beyond a single rating prevents data-driven iteration, keeping the app in a static state.
The SWOT
- Multi-protocol discovery barrier against hardware-specific utilities
- Live timestamped logging enables real-time command verification
- 14-bit CC validation ensures high-resolution parameter compatibility
- Integration of MIDI-over-network presets for RTP-MIDI users
- Expansion into automated test-scripting for hardware developers
Next best moves
Audit MIDI API compatibility because the app has not been updated in 241 days → maintain core functionality
The counter-intuitive read
The lack of monetization is not a weakness…
Read the full takeSince the last report: The app remains in a static, maintenance-only state with no functional changes or updates recorded over the last 241 days. The primary shift is a more precise articulation of the app's competitive risks and market position within the SWOT and outlook sections.
Bottom line
MIDI-Probe provides a high-utility diagnostic tool for niche hardware troubleshooting, but the 8-month development silence suggests the project is in maintenance mode. Resuming support with automated test-scripting would unlock value for hardware developers beyond simple monitoring.
