How do I create sequencer notes in Dr. REX?
Creating Sequencer
Notes
To be able to make your REX loop start at the same time as other sequencer
or pattern data, you first have to create sequencer notes from the slices:
1. Select a sequencer track connected to the Dr.Rex device.
2. Set the left and right locators to encompass the section you want to
fill with REX notes.
You may want to make sure that this area doesn’t contain any notes al-ready,
to avoid confusion.
3. Click the To Track button on the Dr.Rex panel.
Now, the program will create a note for each slice, positioned according to
the timing of the slices. The notes will be pitched in semitone steps, with the
first note on C1, the second on C#1 and so on, with one pitch for each slice.
If the area between the locators is longer than the loop length, the loop notes
will be repeated to fill out the loop.
The loop notes in the Arrange View…
…and in the Edit View.
Activating playback in the sequencer will now play back the notes on the se-quencer
track. These in turn will play back the slices in the Dr.Rex device, in
the correct order and with the original timing maintained. Now the fun begins!
– You can change the groove in the loop by quantizing or moving
notes.
– You can transpose notes to change the order of the slices on play-back.
– You can use the Alter Notes function in the Change Events dialog
(see page 29) to scramble the loop notes – without destroying the
original loop timing.
– You can remove and draw new notes, creating any kind of variation.
– You can use the User Groove function to apply the rhythmic feel of
the loop to notes on other sequencer tracks.
For details about editing in the sequencer, see page 20.
! Note that if you have created sequencer notes from a REX file, you
cannot load a new REX file into Dr.Rex and play it from the existing
track. Well, you can, but it will not play back properly. If you have
created notes in this way, and want to change the REX file, first de-lete
the notes, then use the “To Track” command again after having
loaded the new REX file.
You can also export the REX file as a MIDI file, as described on page 174.

The estimated required monthly payment shown which excludes taxes and delivery equals the amount financed divided by the number of months in the promo period, rounded up to the next cent. During the last month(s) of the promo period the required monthly payment may be reduced due to this rounding. These payments apply only with the financing offer shown. If you make these payments by the due date each month, you should pay off this amount financed within the promo period, if it is the only balance you are paying off. If you have other balances on your account, this payment will be added to any other minimum monthly payments.
