INTRODUCTION
Congratulations on your purchase of a Yamaha RX21 Digital Rhythm Programmer!
Your RX21 represents the crystallization of the most sophisticated electronic music
technology, combining advanced microcomputer control with a top-quality digital PCM
sound storage and reproduction system. With the RX21 you will be able to program
virtually any type of rhythm pattern, and since the instrument sounds are digitally recorded
they are indistinguishable from live percussion instruments.
To ensure that the RX21 will give you maximum performance and versatility, we urge
you to read this operation manual carefully before attempting to operate the unit. A handy
fold-out diagram of the RX21 control panel allows you to instantly locate any controls
mentioned in the text, so that you can familiarize yourself with the operations as easily
and effortlessly as possible.
The 44 preset patterns stored in the RX21’s memory are detailed in the accompanying
RX21 PATTERN BOOK. It also contains other rhythm patterns for you to try out, a pattern
chart in which you can note down your own personally programmed patterns, and a
song chart.
