Mackie Tracktion

Use racks to set up sophisticated effects routings

By Craig Anderton
Objective: Set up a series/parallel effects “filter” that can be dragged into a track’s signal chain.

Background:A Tracktion rack is a signal processing module that can host multiple plug-ins, patched in any combination of series and parallel routings. You can then insert the completed rack into a track.

Step by Step: This is a simple workflow — just follow the steps in sequence.

1. Click on the Racks box to show the rack configuration area.

2. Click on New Rack and select Create New Empty Rack.

3. Drag a new “filter” (potential plug-in) into the rack. When you release the mouse button, select the desired plug-in. When asked if you want to auto-connect the filter, say “no.”

4. Keep adding plug-ins by dragging filters into the rack.

5. Patch the plug-in ins/outs together by clicking on one point, dragging it to another, then releasing. In this example, two pairs of effects have been wired in series, and these two series chains have been patched together in parallel.

6. Click within the rack filter to select it (as indicated by a red outline). Drag the object that says “Drag here to insert an instance of this rack” into the desired location in the track’s signal chain. Note the red background that shows where the rack will end up after being dragged.


• To edit a rack plug-in, click on it. Its interface will float if it’s a non-Tracktion effect; otherwise the interface will appear in the Rack Filter Properties panel.

• To disconnect a “software patch cord” within the rack, click on the cord itself (not an end), and drag it away.

• From within the Rack Filter Properties panel, you can rename/add/delete inputs and outputs, as well as manage rack presets.

• Click on the Racks button again to hide the rack filters, thus allowing more screen space for tracks.
