M9 Docs   Project Browser

MuLab 9 features a multi-functional browser where you'll find all samples, sequences etc in your project, but also your MUX presets, VST / CLAP plugins, sample files, MuClips, MIDI files etc...
It's a central place from which you can easily preview and drag-drop objects around.

The project browser can be opened via Project Browser button at the right of the main menu.

The browser has 3 main parameters:

  • What: What defines what kind of items you want to see. Hold your mouse over the "What" buttons at the top, a tool tip will tell you what they represent.
  • Where: Where defines the folder location.
  • Which: Which defines a name filter for example if you input "bass" you'll only see items with "bass" in the name. This filter is case-insensitive.

You can drag-drop items from the browser to various parts of the app, and you can also drag-drop objects from your project into the browser so to save them.
Drag-drop is a very intuitive way of working and MuLab supports all kinds of drag-drops, too many to list all drag-drop relations individually.
So how do you know which drag-drops work?
Well just try it and if the mouse cursor shows a drag-drop object picture then it's working, else if the mouse cursor shows a stop sign, it's an unsupported drag-drop operation.

About the "Resend" feature: When you have drag-dropped an object on something, the Resend will auto drag-drop the current selected item to that last location again.
Sounds theoretical so a practically example:
If you have dropped a plugin somewhere then you can quickly resend = redrop another plugin on that same destination, which may be more handy than having to effectively drag-drop again.
Note you can also assign a shortcut to this Resend function!

Browser Presets

Most probably when using the browser intensively, switching the What-Where-Which all the time could become a bit uncomfortable.
That's why you can setup Browser Presets. That's done via the smiling folder button.
When you have a frequently used combi of What-Where-Which , then save it as a Browser Preset, so you can quickly recall it in 2 clicks.
And if 2 clicks are too much for your very favorite browser presets, eg. your favorite kick samples, you can setup a Browser Preset Button that will appear on the browser so that you can show your preferred content with a single click!

Previewing Items

Most items in the browser can be previewed.
When automatic previewing is enabled, selecting an item will preview automatically it.
When automatic previewing is off, you can still double-click an item to preview it.
Auto-preview can be switched on/off using the [A] button at the bottom-left of the browser.

As soon as you have previewed an item, there is a "Previewer" MUX in the Project Modular Area.
Inside that Previewer MUX, modules are automatically added/removed depending on what's being previewed.
This Previewer MUX also contains a "Previewer Rack" where you can control the volume of the preview.
You can easily show this rack using the rack button at the bottom of the browser.
You can also easily change the preview volume using the volume knob at the bottom of the browser.
The Previewer MUX itself is switched on / off automatically when necessary so that it doesn't use CPU when not being used.

When previewing MIDI files: MuLab automatically uses a basic SMF player for a relevant sound preview.
You can setup your own SMF Player in User/Library/MUX/Instruments/Templates/SMF Player.Mux
If in the Previewer rack the SMF Player slot is powered off then MIDI files are previewed via the focused module. (eg. focused track / rack).

Attention: Previewer rack slots 1 and 2 are reserved. If you want to add insert effects, put them in slot 3, 4, ...


  • The favorite folders listed in the browser's "Where" list are the same favorites as listed/managed in the file/folder browser that pops up when you choose "Where" -> "Browse For Folder..."
    In that popup window there is a favorites folder icon button via which you can manage your favorite folders.
  • You can also use the browser in a floating window via the browser's options menu or via Edit Preferences.
    When the browser is docked, a single click on the splitter at its side quickly minimizes/maximizes the browser.
  • The browser's setup is stored in the project file.
    You could create/update your 'New' project template so that the browser is setup as you want whenever you do New Project.
    For more info on project templates, hover the "Save As Template" menu item.
