REX files .rx2, .rcy or .rex REX files are created in another Propellerheads application, the ReCycle loop editor. REX
files contain audio loops chopped into slices, with one slice for each significant beat in the
loop.
REX files can be imported to Audio Tracks in Reason and are automatically converted to au-
dio files. By loading a REX file into the Dr. Octo Rex Loop Player device, you can play back
the loop in virtually any tempo (without affecting the pitch), manipulate individual beats in the
loop, extract timing info, etc.
Note that you can also load REX files into the samplers, the Redrum drum machine and Kong
Drum Designer.
Audio files and Samples .wav, .aif, mp3 etc. Audio files of various formats, resolutions and sample rates can be imported to Audio Tracks
in Reason. All sampler devices in Reason can also load and play back samples and audio files
in these formats. You can use files of different formats in the same device - one drum sound
can be an 8-bit sample, the next a 16-bit sample, etc.
The audio file format support differs depending on which computer OS you are using.
In Mac OSX10.7, the following audio file formats are supported:
.wav (not floating point), .aiff (not floating point), .3g2, .3gp, .mp1, .mp2, .mp3, .mpeg, .mpa,
.snd, .au, .sd2, .ac3, .aac, .adts, .amr, .caf, .m4a .m4r and .mp4.
In Windows 7, the following audio file formats are supported:
.wav (not floating point), .aif (not floating point), .mp3, .aac, .m4a and .wma
SoundFont Bank .sf2 The SoundFont format was co-developed by E-mu Systems and Creative Technologies and is
used with many audio cards and software synthesizers. SoundFont banks store wavetable
synthesized sounds, allowing users to create and edit multi-sampled sounds in special
Soundfont editing programs. The SoundFonts can then be played back in wavetable synthe-
sizers, typically on audio cards, thereby effectively turning an ordinary sound card into a sam-
pler.
The NN-XT and NN19 Samplers and the Redrum drum machine allow you to browse and
load SoundFonts. Regardless of which editing program was used to create them, these banks
are similarly and hierarchically organized, with folders for instruments, presets, samples etc.
The NN-XT, NN19 and the Redrum lets you load individual samples and presets from a
SoundFont bank, but
not the complete SoundFont.
Rack Extension Patch .repatch These are patches for Rack Extension devices. All Rack Extension devices use the same file
extension but the patch files contain different data depending on which device was used for
creating them.
