Adding Loops

To add one or several (up to 8) loops into the Dr. Octo Rex Loop Player, proceed as follows:

1.	Unfold the Loop Editor panel.

2.	Select the Loop Slot you wish to add the (first) REX loop into.

3.	Open the REX Loop browser by clicking the folder button to the left of the Loop Slot buttons.

Alternatively, select “Browse Loops...” from the Edit menu or the device context menu.

4.	In the Browser, locate and select the desired loop(s).

You can listen to the loops before loading by using the Preview function in the browser.

To select several loops, hold down [Ctrl](Win)/[Cmd](Mac) and click.

To select a range of loops, hold down [Shift] while clicking the last file.

5.	Click the Load button in the Browser to load the selected file(s) in the Loop Slot(s).

If you have selected and opened several loops, the first loop will load in the selected Loop Slot and the rest will load in consecutive Loop Slots.

Loading new REX files will replace any files currently in the slots.

Alternatively, select the REX loop(s) in the Browser and drag and drop it/them on the Loop Editor panel section, or on a Loop Slot button on the Controller Panel.

If you have selected several loops, the first loop will load in the selected Loop Slot and the rest will load in consecutive Loop Slots.

If you drag a single REX loop from the Browser and drop on the Controller Panel (not on a Loop Slot button), the REX loop will load into Slot 1 and all other Slots will be cleared.

Loading Loops “On the Fly”

Another practical method for checking out loops, is to load them “on the fly”, i.e. during playback. This is especially useful if you want to check out a number of loops against other sequencer data and patterns previously recorded. Proceed as follows:

1.	Activate the Enable Loop Playback button on the Dr. Octo Rex device and start sequencer playback.

The REX loops and the sequencer are synced.

2.	Now load a new REX file by using the Browser in one of the usual ways.

After a brief silence, the new file is loaded, and sync is maintained.

3.	Repeat step 2 as necessary until you have found a suitable loop.

If you are trying out loops within the same folder, the quickest ways to select a new loop is to use the arrow buttons next to the loop name display.

Or, you can click in the loop name display and select a new loop from the pop-up menu that appears.

Removing Loops

To remove a loop from a Loop Slot, select “Remove Loop” from the Edit menu or device panel context menu.

Cut/Copy and Paste Loops between Loop Slots

To cut or copy a loop from one Loop Slot and paste into another, proceed as follows:

1.	Click the button of the Loop Slot that contains the loop you want to cut or copy.

2.	Select “Cut Loop” or “Copy Loop” from the Edit menu or panel context menu.

You have to context-click on the panel (not any button or knob) to access the correct context menu.

3.	Click the destination Loop Slot button and select “Paste Loop” from the Edit menu or panel context menu.

Now, you can edit the slices of the pasted loop as desired, see “Slice handling”.
