SoundMiner v6

Here's a fun one that works MOST of the time. Set search path in Line 1 or template if you have multiple radium folders

Search your Radium Presets

const searchPath = ///SET YOUR SEARCH PATH HERE something like `/Users/ocdsound/Library/Application Support/SoundminerV5/Radium`
const sM = sf.ui.app("com.soundminer.v6")
const raidWin = sM.windows.whoseTitle.startsWith('Radium - ').first
const radiumMenu = sM.windows.whoseTitle.is("menu").first.children.whoseRole.is("AXWindow").whoseTitle.is("Soundminer").first
const patchLoadWindow = sM.windows.whoseTitle.is("Please choose a preset").first.splitGroups.first

//Search Radium Patchs
function radiumPatchSearch() {

    var radiumFileCandidates = sf.file.directoryGetFiles({
        path: searchPath,
        isRecursive: true,
    }).paths.filter(p => p.match(/\.(Radium|ra88)$/i) && !p.includes("Autosave"))


    var selectedPath = sf.interaction.popupSearch({
        items: radiumFileCandidates.map(p => ({
            name: p.replace(searchPath, '').substring(1),
            path: p,
        })),
    }).item.path;

    return selectedPath;
}

function navigateToInDialog(path) {
    //Get a reference to the focused window in the frontmost app:
    var win = sf.ui.frontmostApp.focusedWindow;

    var sheet = win.sheets.first.elementWaitFor({ timeout: 500 }, 'Could not find "Go to" sheet in the Save/Open dialog').element;
