Why we like it

Live Midi Visualizer earns its place in the superhive library as a focused Blender add-on for turning live MIDI input into viewport feedback. Worth knowing before you download: it visualizes MIDI messages rather than detecting audio, and does not convert MP3 or WAV files into notes.

What is Live Midi Visualizer - Real-Time Midi Controller Add-On?

Live Midi Visualizer, also known as MIDIFlare Live, is a Blender add-on that listens to incoming MIDI messages and turns them into visual feedback inside the viewport. Connect a MIDI controller, press keys, pads, knobs, or buttons, and matching objects react in real time. It can also generate a visual MIDI controller layout inside Blender.

When a key is pressed, the matching key object can move or glow; pads can light up when hit, and knob objects can rotate based on MIDI CC values. The add-on supports piano keys, drum pads, knobs using MIDI CC values, and buttons or controller actions, with animated key press and release feedback and a debug display for incoming MIDI messages. It is useful for Novation Launchkey-style controller visuals.

It is aimed at music creators, MIDI controller demos, educational videos, audiovisual experiments, and live performance visuals. The add-on handles MIDI input visualization rather than audio detection, so it does not convert MP3 or WAV files into MIDI notes. It runs on Blender 3.6 through 5.1.

Frequently asked questions

What Blender versions does Live Midi Visualizer support?

Live Midi Visualizer runs on Blender versions 3.6 through 5.1, and the render engines listed are Blender-Internal, Cycles, and Eevee. It is released under the GPL license. Because it reads live MIDI, your MIDI device also needs to be detected by your operating system before Blender can pick it up. If you are working within that version range, the add-on's real-time viewport visualization should be available to you.

Does Live Midi Visualizer need a MIDI controller connected?

Live Midi Visualizer requires a MIDI controller that your operating system can detect, since it listens to incoming MIDI messages rather than generating them. Once your device is connected, open the Live MIDI panel in Blender, refresh the MIDI device list, select your input device, and start listening. From there you can play keys, pads, knobs, or buttons and see matching objects react in real time inside the viewport.

Can Live Midi Visualizer turn an MP3 or WAV file into MIDI?

Live Midi Visualizer is built for MIDI input visualization, not audio detection, so it does not convert MP3 or WAV files into MIDI notes. It listens to live MIDI messages coming from a connected controller and turns them into visual feedback inside Blender. If your goal is to react to played MIDI data from keys, pads, and knobs, that is what this add-on handles, but audio files fall outside its scope.

How do I set up Live Midi Visualizer in Blender?

Live Midi Visualizer follows a straightforward setup: install and enable the add-on in Blender, connect your MIDI controller to your computer, then open the Live MIDI panel, refresh MIDI devices, select your input device, and start listening. Once you play, the connected objects react in real time. Note that some setups may require installing MIDI Python dependencies into Blender's Python environment, and your MIDI device must be detected by your operating system first.

Is Live Midi Visualizer free?

Live Midi Visualizer is listed as free in this catalog, so check the developer's page for current pricing and licensing details before you download. The add-on is distributed under the GPL license and, according to its listing, includes product updates and a support period offered directly by the developer, Egon Castle. For the most accurate and up-to-date terms, the developer's page is the place to confirm.
