DR. REX LOOP PLAYER
186
Introduction
The Dr.Rex Loop Player is capable of playing back and editing files created in
ReCycle, another product created by Propellerhead Software. ReCycle is a pro-
gram designed especially for working with sampled loops. By “slicing” a loop
and making separate samples of each beat, ReCycle makes it possible to
change the tempo of loops without affecting the pitch and to edit the loop as if it
was built up of individual sounds.
ReCycled Loops
To fully understand Dr.Rex you need to understand what it means to ReCycle a
drum loop. Imagine that you have a sample of a drum loop that you want to use
in a track you are working on. The loop is 144 bpm and your track is 118 bpm.
What do you do? You can of course lower the pitch of the loop, but that will
make the loop sound very different, and if the loop contains pitched elements
they will no longer match your song. You can also time stretch it. This won’t alter
the pitch, but will make the loop sound different. Usually it means that you loose
some “punch” in the loop.
Instead of stretching the sample, ReCycle slices the loop into little pieces so
that each drum hit (or whatever sound you are working with) gets it's own slice.
These slices can be exported to an external hardware sampler or saved as a
REX file to be used in Reason. When the loop has been sliced you are free to
change the tempo any way you want. You can also create fills and variations
since the slices can be moved around in the sequencer.
About File Formats
Dr.Rex can read files in the following formats:
D REX (.rex)
This is the file format generated by previous versions of ReCycle (Mac plat-
form).
D RCY (.rcy)
This is the file format generated by previous versions of ReCycle (PC plat-
form).
D REX 2 (.rex2)
This is the ReCycle file format for both Mac and PC platforms generated by
ReCycle version 2.0. One of the differences between the original REX for-
mat and REX2, is that the REX2 format supports stereo files.
! Unlike the other audio devices, Dr.Rex does not load or save file in-
formation in a “Patch” format. The REX file and the associated
panel settings is instead saved in the Song (.rns) file.
✪ If you have made adjustments (pitch, level etc.) to a REX loop that
you wish to use in another Song, you can simply copy the whole
Dr.Rex device from one song to another.
