Volume Control

Author: Sander

Script Version: 2

Minimum CoyoteMIDI Build: 771

Allows you to control the volume of your system directly from a MIDI control. On Windows, you can also target a specific process or the foreground process instead.

By default, the script will automatically use the value of the MIDI event that triggered the translation, so that the position of a CC fader or knob, or the velocity of a note, will translate to the volume. When triggering the translation from a control change event, it is best to set the condition of the CC input to ‘any’.

You can also select the ‘increment_volume’ script to add or subtract from your system’s volume by a set amount without using the MIDI input’s value.

It adds the following parameters to a translation:

Target (Windows): The process name to change the volume of, or “*” for the system volume, and “foreground” for the current foreground application.

Foreground Key (Windows): The key to hold down to override the target with the current foreground application.

Ignore Key: The key to hold down for this script to do nothing while the input MIDI is triggered.

Amount (increment_volume subscript only): The amount to increase or decrease the volume with.
