REDRUM
88
Introduction
At first glance, Redrum looks styled after pattern-based drum machines, like the
legendary Roland 808/909 units. Indeed, it does have a row of 16 step buttons
that are used for step programming patterns, just like the aforementioned clas-
sics. There are significant differences, however. Redrum features ten drum
“channels” that can each be loaded with an audio file, allowing for completely
open-ended sound possibilities. Don’t like the snare - just change it. Complete
drum kits can be saved as Redrum Patches, allowing you to mix and match drum
sounds and make up custom kits with ease.
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 references 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
! All samples are stored internally in 16-bit format, regardless of their
original bit depth or sample rate.
Wave and AIFF are the standard audio file formats for the PC and Mac plat-
forms, 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 Technologies.
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 audio
cards. The samples in a SoundFont are stored hierarchically in different catego-
ries: 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 affect-
ing 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.
