Playing Loops

1.	Make sure the Enable Loop Playback button is on (lit).

2.	Click the desired Loop Slot button.

3.	Play back the loop by clicking the Run button.

The loop in the selected Loop Slot will play back repeatedly in the tempo set on the Transport Panel. If you change the tempo, the loop tempo will follow.

You can also play the loop once via MIDI, by using the D0 key.

To check out the loop(s) together with other device sequencer data and patterns already recorded, click the sequencer Play button.

The loops will automatically play back in perfect sync with the sequencer.

Switching playback between Loop Slots

Switching playback between loops in different Loop Slots is just like switching a Pattern in a Redrum device, for example.

1.	Activate the Enable Loop Playback button on the Dr. Octo Rex device.

2.	Click the Run button - or start sequencer playback.

3.	Click another Loop Slot button to switch loop.

Selecting Loop Slots that have no loops loaded will result in silence.

The Trig Next Loop function

The Trig Next Loop function determines how long Dr. Octo Rex waits after a Loop Slot button (or a key) is pressed before it actually “gates in” or triggers the loop. This allows for different “precision” when switching between running loops:

Activate the Bar button to make the loops switch at the next bar of the current loop.

Activate the Beat button to make the loops switch at the next beat of the current loop.

Activate the 1/16 button to make the loops switch at the next 1/16th note of the current loop.

Switching Loops using Pattern Automation in the sequencer

Switching between Loop Slots can be automated, by using Pattern Automation in the main sequencer.

When using Pattern Automation, the Trig Next Loop function described above is disregarded - the switching between Loop Slots is instantaneous.

Refer to “Pattern automation recording details” for details about Pattern Automation.

When you use the Pencil tool to draw Pattern Automation clips and select Pattern in the Inspector, the Bank selection is of no importance since Dr. Octo Rex doesn’t make use of Banks.

Triggering playback and selecting Loop Slots from a MIDI keyboard

It’s also possible to control playback, stop and Loop Slot selection in real-time by pressing different keys on a MIDI keyboard. By pressing the keys E0 to B0 you select Loop Slot 1-8 and start playback of the corresponding loop. The loop(s) will play back continuously, one loop at a time, until you press the D#0 key to stop playback, or click the Run button or Stop in the main sequencer. The time between key press and Loop Slot switching is determined by the Trig Next Loop function, see “The Trig Next Loop function”.

Note that the Enable Loop Playback button must be on.

The picture shows what keys should be pressed to select and play Loop Slot and to stop loop playback:

•	To maintain backwards compatibility with Dr. Rex, the D0 key can be used to play back the REX loop in the Loop Slot that currently has Note To Slot focus (see “Note To Slot”).

The loop is played back once (single-shot) and cannot be stopped during this time.
