Visualization

+ The default visualization comes as a plugin of QMidiPlayer. So before using it you + have to enable it first in the plugin manager.
+ To use the visualization, click the Visualization button in the main window.
+ The visualization plugin adds two new option tabs. +

Known problems

+ In some systems closing and reopening the visualization results in a crash. This is + due to a dbus-related conflict in SDL and Qt. +

Options

+ The options listed here are applied after closing and reopening the visualization. +

+ Visualization-Appearance +
- Show Piano: Whether to show the virtual piano in the visualization scene. Currently drawing the piano is very expensive, so it is not recommended to enable this unless you have a beefy computer.
- 3D Notes: 2D notes are used when this is unchecked. Using 2D notes is less resource-hungry.
- Arrange channels on a stair: If checked, virtual pianos will be arranged on a stair-like shape. This option has no effect if virtual piano is not shown.
- Show channel labels: If checked, channel preset will be shown on the left side.
- Show particles: Whether to draw particles. Very resource-intensive!
- Horizontal Visualization: Uses a horizontal visualization style. Overrides everything above except 3D Notes.
- 2D Visualization: Tick this to use a simple 2D visualization instead. Much less resource-demanding.
- Use spectrum instead of piano roll: Draw spectrum-like bars over the piano.
- View distance: This option affects the maximum number of notes rendered on the screen. Only applies to the 3D visualization.
- Note stretch: The length multiplier of notes.
- Minimum note length: Avoid notes that are too short to be visible by adjusting this value.
- Chequer board tint (AARRGGBB): change the color of the chequer board background.
- Background Image: Use a background image instead of the default dull grey color.
+
+ Visualization-Video +
- Enable VSync: Enable vertical synchronization.
- Save Viewport: Restore last camera configuration when the visualization is started.
- Window Width/Height: Change the window size. If the size equals to your screen size, the visualization will start in fullscreen mode.
- FPS: FPS limit of the visualization.
- Supersampling: Supersample anti-aliasing. 1 means no SSAA.
- Multisampling: Multisample anti-aliasing. 0 means no MSAA.
- FOV: Field of view.
- OSD Position: Change position of the on screen display, or simply disable it.
- Font size: Change font size used by the visualization. Useful for HiDPI screens.
+
+ Key-only options
+ Options listed here does not provide an entry in the option GUI. You have to add them to the configuration file manually if they don't exist in it. +
- px py pz rx ry rz (automatically created if save viewport is set to true): Doubles. Saves the last viewport. (px,py,pz): Position of the camera. (rx,ry,rz): Orientation of the camera.
- chActiveColor<channel id 0..15> : Unsigned 32-bit integers. Colors of sounding notes.
- chInactiveColor<channel id 0..15> : Unsigned 32-bit integers. Colors of normal notes.
