Overview

MIDI Portal is a free MIDI monitoring Machine included with iLumidi. Watch traffic flow in Cascade, examine events in Log view, open device-specific windows, and save session logs for deeper troubleshooting.

It runs inside the shared iLumidi environment, making it useful on its own and alongside other Machines as the ecosystem grows.

MIDI Portal uses iLumidi’s CPU/JUCE display path for responsive monitoring, while visual Machines such as MIDI Sketch N’ Etch and Rainbow Rain use the GPU runtime.
