Tired of robotic, machine-gun-sounding autoplayers? HuMidi uses advanced algorithms to make any MIDI file sound like a real, living pianist.
Watch the engine perfectly execute a complex track in real-time.
We didn't just build a macro. We built a virtual pianist.
Built and optimized specifically for Roblox virtual pianos, HuMidi seamlessly translates MIDI files into flawless key presses perfectly matched to the game's input schema.
A full suite of independent controls: velocity dynamics, articulation shaping, chord rolling, timing variance, hand drift correction, and a customizable mistake chance. Dial in exactly how human you want to sound.
Forget muddy, terrible sounding chords. Our adaptive algorithm knows exactly when to press and release the spacebar to keep the harmony clean and beautiful.
Don't let complex songs limit you. HuMidi supports standard layouts and extended 88-key virtual pianos (utilizing Shift and Ctrl combinations) so you never miss a note.
Built with an ultra-lightweight, multi-threaded engine. HuMidi runs in the background with microsecond precision, never slowing down your game.
Everything you need to fine-tune your performance in one sleek window.
An expanded panel puts every humanization control at your fingertips: velocity dynamics, articulation, timing variance, chord rolling, hand drift correction, and more.
Save complete playback configurations as named presets, organized per-MIDI. Reload any performance setup with one click, no re-dialing required.
Switch to light mode or dial in a custom color scheme. HuMidi's new theme editor lets you personalize the look without touching a config file.
Collapse HuMidi down to its bare essentials. The minimized overlay keeps only the controls you need visible, with everything else tucked away.
See how HuMidi evolved into the ultimate virtual pianist.
We are ripping out the old algorithmic rules and replacing them with true intuition. HuMidi's next major feature is a dedicated Machine Learning model built exclusively to master the sustain pedal. By training on the prestigious MAESTRO Dataset V3.0.0, the engine is learning how professional concert pianists actually use the pedal, anticipating harmonic changes rather than just reacting to them.
The biggest humanization overhaul yet. V2.0 expands the performance engine with a full suite of independent controls: velocity dynamics, articulation shaping, configurable timing variance, and a new drift correction system with a tunable decay factor. Added a complete preset system for saving and loading your favorite playback configurations instantly, a real-time transpose slider, a built-in auto-update checker, and UI theme customization. A significant engine tightening pass rounds out the release.
The definitive quality-of-life update. Introduced the interactive timeline visualizer allowing users to scrub and seek through tracks in real-time. Added the highly requested Overlay Mode (featuring customizable window opacity and always-on-top toggles), alongside fully bindable custom hotkeys for seamless background operation while gaming.
Added auto-save config (loads automatically when the application runs and saves on Play). Introduced the option to invert tempo sway weights. Rearranged the GUI and added more behind-the-scenes UX features. Tweaked humanization factors and significantly advanced the dynamic pedal logic.
Fixed playback generation bugs and introduced 88-key layout support for specific experiences. Improved general UI and overall performance. Featured a massive logic overhaul, optimizing the engine and greatly increasing accuracy based on advanced music theory rather than basic assumptions.
The original major release! Brought the core humanization options to life. Evolved the application from a difficult-to-use CLI script into an accessible GUI, allowing users to easily toggle flags, load files, and send assembled commands with a click.
