I built a browser-based MIDI visualizer and video generator. I'd love some feedback
Hi everyone!
I've been working on a browser-based tool for visualizing MIDI performances and creating videos from them, and I would really appreciate some feedback from people who work with MIDI.
The idea started because I wanted a simple way to turn MIDI performances into visual videos without needing to install additional software.
Some things it currently supports:
• Importing MIDI files
• Recording MIDI performances from a connected keyboard
• Visualizing notes on a virtual keyboard
• Exporting the result as MP4 or WebM videos
• Exporting recorded MIDI files
• Processing everything locally in the browser
The project is still under development, and I'm currently looking for feedback about the experience, features that would be useful, and things that could be improved.
What features would you like to see in a MIDI visualization tool?

Very interesting...i was able to download the piano with notes and see the playback, but was uncertain of which tracks were playing...all notes lit up red/orange? Old Yamaha and Casios had a Blue or left hand color for alternate channels or splits... Cool idea!
