HuMidi ~ ROBLOX Piano Player


HuMidi is a universal piano auto player for ROBLOX. It plays even the most generic MIDI file with great depth, thanks to the humanization and automatic sustain pedal generation algorithms. The pedals are generated with a thorough analysis of the MIDI data, adding more depth to your performance that no other MIDI players could!

Personally have been tested in:

  • Visual Pianos
  • Starving Pianists
  • Digital Piano
  • Piano’s Got Talent

This tool is universal, as long as the piano in-game allows to be played on a keyboard.

Features:

  • MIDI auto player
  • Humanization options
  • Automatic sustain pedal (even if your MIDI doesn’t have the data!)
  • Visualization
  • Pause and resume
  • Scrubbing / seeking – You don’t have to play from the beginning every time, just skip to the part you want to play!
