About file formats
Redrum reads two basic types of files:
Redrum Patches
A Redrum patch (Windows extension “.drp”) contains all settings for all ten drum sound channels, including file refer-
ences to the used drum samples (but not the actual drum samples themselves). Switching patches is the same as se-
lecting a new drum kit.
Drum Samples
Redrum can read and play back sample files of the following formats:
•Wave (.wav)
AIFF (.aif)
SoundFonts (.sf2)
REX file slices (.rex2, .rex, .rcy)
Any bit depth
•Any sample rate
Stereo or Mono
Wave and AIFF are the standard audio file formats for the PC and Mac platforms, respectively. Any audio or sample
editor, regardless of platform, can read and create audio files in at least one of these formats, and some of them in
both formats.
SoundFonts are an open standard for wavetable synthesized audio, developed by E-mu systems and Creative Tech-
nologies.
SoundFont banks store wavetable synthesized sounds, allowing users to create and edit multi-sampled sounds in
special Soundfont editing programs. The sounds can then be played back in wavetable synthesizers, typically on au-
dio cards. The samples in a SoundFont are stored hierarchically in different categories: User Samples, Instruments,
Presets etc. The Redrum allows you to browse and load single SoundFont samples, not
entire soundfonts.
REX files are files created in ReCycle – a program designed for working with sampled loops. It works by “slicing” up
a loop and making separate samples of each beat, which makes it possible to change the tempo of loops without af-
fecting the pitch and to edit the loop as if it was built up of individual sounds. The Redrum lets you browse REX files
and load separate slices from it as individual samples.
