Fig. — MIDI Matrix MonitorSchematic

A conceptual overview of MIDI channels 1–16, not audio-level meters or a routing matrix. Notes, velocity, controllers, pitch bend, pressure and program changes are observed per channel; system events are separate. The display monitors events. The AUv3 can also pass received MIDI onward; no channel-remapping operation is depicted.

Is this you?

  • 01You play MIDI guitar (or a keyboard MIDI controller) and need confirmation of what's happening with each string.
  • 02You use MPE and want pitch bend, pressure and note data separated rather than interleaved.
  • 03You are debugging a controller, a converter or a piece of hardware and need to clealy see the CCs it actually transmits.
  • 04You have multiple input MIDI istruments and need quick and easy acces to their MIDI monitoring configurations.

What it is

MIDI Matrix Monitor is a visually customisable MIDI monitor for macOS and iPadOS, built for MIDI guitarists, MPE users, producers and performers with complex MIDI setups.

Instead of combining every MIDI event in one stream, it separates incoming MIDI activity by channel — so notes, velocity, pitch bend, aftertouch and controller data can be read in real time, per channel, at a glance.
