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 already, 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.

Activating playback in the sequencer will now play back the notes on the sequencer 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 playback.

You can use the Alter Notes function in the Change Events dialog 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.

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 delete the notes, then use the "To Track" command again after having loaded the new REX file.
