13. Background Images and Encoder Colors

Background Images

You can load background images to each page of the MPH. You can drag and drop an image, jpg or png format to the current page you are working on, from your file explorer. The image must be of 1920 x 1080 px resolution, jpg or png. The image will be saved when saving a preset and be placed in the Images folder on the same folder level as the Presets folder, in the MP/Host folder on your computer.

Update June 18th, 2026

The MP Host now can load webp images for background as well. There is a new section in the right click menu named Page Background. You can download a library of 800 image backgrounds and place them in the /images/default folder. Enable the Random page background option so that each time you load a plugin from the plugin list, it will load a new background image from the default folder.

Steps to enable automatic background images:

1. Select option: Open Images Folder
2. Select option: Download Images. It will download a zip file. Extract the images of the zip file in the /images/default folder.
3. Enable Random Background.
4. Load a new plugin and it will assign a randoma backgrounf image to each page.

Encoder Background Colors

Right/Left clicking on the inner area of each encoder will display a palette of colors which you can select to color code the encoders. It’s a good practice to color encoders that belong in the same group, like an ADSR envelope.  These encoder assigned colors are saved in multi host and single host presets.

You can disable the left click to show not show the color palette by editing the host.properties file in a text editor and changing the last line:
<VALUE name="disable_left_click_color_palette_on_encoders" val="0"/>

to

<VALUE name="disable_left_click_color_palette_on_encoders" val="1"/>

Then, save the file. 

Remove the MP Host and load it again and now it should not show the color palette when left clicking in the center of the encoder.
