MIDI-humanizer

The MIDI Humanizer is a tool that allows you to humanize MIDI files by adding random variations to note timing, duration, and velocity. It provides a graphical user interface (GUI) built with PySide6, making it easy to select MIDI files, adjust humanization parameters, and save the processed files.

Features

• Select MIDI File: Choose a MIDI file using a file dialog.
• Adjust Humanization Parameters:
  • Time Offset: Randomly shift note start times within a specified range.
  • Duration Offset: Randomly adjust note durations within a specified range.
  • Velocity Offset: Randomly change note velocities within a specified range.
  • Duration Percentage: Reduce note durations by a specified percentage before applying offsets.
• Multiple Track Processing: Humanize each track individually while considering notes from all tracks to prevent overlapping.
• Save Processed File: Save the humanized MIDI file with a _humanized suffix in the same directory.
