MIDIVisualizer 5.3(1)

This is a supplementary update to v5.3 which is fully compatible with it.

MIDIVisualizer 4.0

There are a lot of new things in this release so I'm upgrading MIDIVisualizer to version 4. Thank your for using this application and for your feedback!

New features:

• Visual elements (notes, score, particles, flashes) can now be toggled and re-ordered as a series of layers (#23). Click on "Show layers..." to display the list of layers, you can drag-and-drop them to customize their order.
• A background image can now be defined, with support for transparency (#19).
• Keys on the keyboard are highlighted when they are pressed (#24).

Improvements:

• You can now load as many particle images as you wish, and they will be converted to grey levels.
• The initial track position can now be adjusted (#18).
• The user interface has been cleaned up by regrouping options in categories.

Bug fixes:

• Initial position of the particles has been adjusted to align with the notes (#33).
• An issue with the particles on both Nvidia and Intel GPUs has been fixed (#7, #22, #28).

MIDIVisualizer 3.4

Improvements:

To avoid notes at the very beginning being hidden by the keyboard, the initial position of the track is now shifted (see #18).

Bug fixes:

Fixed a bug related to the particles on OpenGL < 4.0 (see #17).

MIDIVisualizer 3.3

Improvements:

• Notes can now be hidden.
• Colors for the background lines, texts, keyboard, sharp/flat keys can be customized.
• Flashes can be tinted and resized.
• You can access debug options by pressing the 'd' key, and can now dump all parsed MIDI events and generated notes in the console log.

Bug fixes:

• Controller pressure and unknown MIDI events are now ignored when computing a track timing.
• Updated GLFW on macOS, should improve Mojave performances.

MIDIVisualizer 3.2

New features:

• You can now export a track as a series of PNG frames in a directory. Those can then be used in video editing tools to generate a video without the performance issues of direct screen recording. The export framerate can be defined. Note: The export process can take a long time, be sure to look into the console log to track down the progress.

• The attenuation speed of the blur effect can now be adjusted, to avoid large glowing regions when many notes are playing on screen.
