This command creates one or more modulations targeting the selected tracks. It's particularly useful for creating a group of modulators all having the same modulation type, as in scale modulation for example. Instead of creating the modulators one by one in the modulations bar, it's easier to create them all at once using this command.
At least one track must be selected in the track view for this command to be enabled, because the track selection determines which tracks will be modulated. The command displays a dialog, allowing you to select one or more source tracks and pick a modulation type. Press OK to create the modulations. For help with selecting multiple items, see list controls. It's recommended to keep the modulations bar visible while using this command so that you can see its effects. This command is also accessible via the Insert Group item on the modulations bar's context menu.
You also have the option to sequentially distribute one source to each selected track. To do this, check the Modulation dialog's Distribute option. This is particularly useful when creating index modulation for a chord. Instead of assigning a different index modulator to each chord voice one by one, you can assign them all at once. For example if tracks 1, 2, 3 are selected, and sources 4, 5, 6 are distributed to them, after the command, 4 modulates 1, 5 modulates 2, and 6 modulates 3. Note that if Distribute is checked, the number of source tracks must match the number of selected tracks, otherwise an error message is displayed.
