Logic Pro X: Freeze Modus

Thanks for your patience with this one @Josh_Ha

Let me know if this script works for you.

const logic = sf.ui.logic;
logic.invalidate();
logic.appActivate();
const inspector = logic.mainWindow.inspector;
const inspectorList = inspector.children.whoseRole.is("AXList").first;
const channelPanels = inspectorList.groups;
const trackPanel = channelPanels.find(panel => panel.children.some(child => child.value.value === "Track:"));
const disclosureTriangle = trackPanel.childrenByFullRole("AXDisclosureTriangle").first;

// Ensure the "Track:" panel is open.
if (!disclosureTriangle.isCheckBoxChecked) {
    disclosureTriangle.elementClick();

    // Wait needed for panel to expand
    sf.wait({intervalMs:200});

    //Invalidate the "Track:" panel in case it was closed
    trackPanel.invalidate();
}

const trackPanelScrollArea = trackPanel.scrollAreas.first;
const trackPanelTable = trackPanelScrollArea.tables.first;
const trackPanelTableRows = trackPanelTable.childrenByFullRole("AXRow:AXTableRow");
const freezeModeRow = trackPanelTableRows.find(row => row.children.first.value.value === "Freeze Mode:");
const freezeModePopup = freezeModeRow.children.allItems[1];

if (freezeModePopup.value.value === "Source Only") {
    freezeModePopup.popupMenuSelect({ menuPath: ["Pre Fader"] });
} else if (freezeModePopup.value.value === "Pre Fader") {
    freezeModePopup.popupMenuSelect({ menuPath: ["Source Only"] });
}

Thanks for requesting this. When I have time I plan on turning this into a command template to control other parameters in the Track and Region panels.
