How can I move the mouse cursor to an active fader window in Pro Tools?

Hi @Dan_Oxer

Try this script. :-)

function focusSendFader({ sendNumber }) {
    // Ensure the Pro Tools main window is active
    sf.ui.proTools.appActivateMainWindow();

    // Get the corresponding letter for the send number
    // Convert number to corresponding letter (1 = 'a', 2 = 'b', etc.)
    const sendLetter = "abcdefghij"[sendNumber - 1] || null;

    // Toggle the send visibility for the selected track
    sf.ui.proTools.selectedTrack.trackSendToggleShow({ sendNumber });

    if (sf.ui.proTools.mainTrackOutputWindow.exists) {
        // Wait for the output window to open and validate that the correct send is displayed
        sf.waitFor({
            callback: () => {
                const outputViewSelector = sf.ui.proTools.mainTrackOutputWindow.buttons.whoseTitle.is("Output View selector").first;
                return outputViewSelector.value.invalidate().value === `send ${sendLetter}`;
            },
            timeout: 2000,
        }, `Send Number ${sendNumber}'s output window did not open.`);

        // Locate the volume slider
        const volumeSlider = sf.ui.proTools.mainTrackOutputWindow.sliders.whoseTitle.is("Volume").first;
        // Get the frame of the slider
        const sliderFrame = volumeSlider.frame;

        // Calculate the center position of the volume slider
        const targetMousePosition = {
            x: sliderFrame.x + (sliderFrame.w / 2),
            y: sliderFrame.y + (sliderFrame.h / 2),
        };

        // Move the mouse to the calculated position
        sf.mouse.setPosition({ position: targetMousePosition });

        // Click the volume numerical text field to activate it (Uncomment this line if you want to be able to scroll your mouse to change the sennd volume)
        //sf.ui.proTools.mainTrackOutputWindow.textFields.whoseTitle.is("Volume Numerical").first.elementClick();
    }
}

focusSendFader({ sendNumber: 1 });
