## Shader Properties

### Beats Per Minute

Parameter ID: `MGBEATSHADER_BPM` · Range: [0.00..200.00]

Use this setting to define the rhythm's frequency, i.e., how often the **Range Curve** should cycle (ping-pong) per minute of animation (when the peak is equal to 100%).

### Peak Range

Parameter ID: `MGBEATSHADER_PEAK` · Range: [0..100%]

This is the effect that the curve at the left has over time on the shader's color gradient at different peak intervals.

If this slider is set to 100%, the **Range Curve** will be repeated in a ping-pong motion (i.e., back-and-forth). The animation will start at frame 0 at the center of the defined curve. If a value less than 100% is defined, the curve will be scaled horizontally from left to right, thus leaving a **null zone** at the right of the graph. As shown in the image above, the double heart beat will beat quicker when set to 50%. After each second beat nothing will occur while the **null zone** is played.

### Range Curve

Parameter ID: `MGBEATSHADER_SHAPE`

Use this curve to define the mix between white (maximum) and black (minimum). This curve will be cycled according to the **Beats Per Minute** setting.

### Inverse

Parameter ID: `MGBEATSHADER_INVERSE`

Use this setting to invert the effect of the shader.
