INTRODUCTION TO THE SR18

Welcome to the SR18 Professional Drum Machine. The SR18 allows you to quickly and easily program
drum, percussion and bass sounds into rhythm Patterns and to turn these Patterns into Songs.
Let's begin with a quick explanation of some of the key elements:
PATTERNS VS. SONGS
PATTERNS – When recording with a drum machine, it's often easier to divide a song into shorter
individual Patterns and work on these rather than record an entire song. A typical Pattern might be
8,16, or 32 beats long, and correspond to a verse, chorus, bridge, instrumental, intro, etc. Think of
Patterns as the building blocks for your Songs. The SR18 holds 100 Preset (i.e., can't be edited)
Patterns and 100 user-programmable Patterns, each of which can be from 1 to 128 beats long.
SONGS are
sequenced together.
program your patterns in the order in which they should
be played, or you can select Patterns in real-time and
the SR18 will remember your performance.

THE 2 TYPES OF PATTERNS

The SR18 introduces exciting new Song construction techniques. The SR18 excels at live
performance—something usually not associated with drum machines. The key to using these advanced
features is to understand the different types of available Patterns.
PRESET Patterns provide a variety of rock, jazz, pop, and other rhythms programmed by
professional drummers.
USER Patterns are Patterns you can program, edit, and save. The PRESET/USER button selects
between these two master banks of Patterns. The only way to modify a Preset Pattern is to copy it
to a User Pattern, where it can be edited.

THE 4 SUB-PATTERNS

There are 100 of each type of Pattern, numbered 00-99. However, each numbered Pattern actually
contains four different "sub-Patterns":
A pair of independent MAIN Patterns (A and B, selected by their respective buttons).
A pair of associated FILL Patterns (A Fill and B Fill, selected by pressing the FILL button when
either A or B is selected). The Fills primarily provide transitional Patterns between Main Patterns,
which makes for more realistic drum parts. The associated Fill Patterns share the same length,
Drum Set, and name as their Main Patterns (e.g., if A is 16 beats, A Fill is 16 beats). Otherwise,
they are independent.
The reason for pairing the two different A and B Patterns together is simply so that you can switch back
and forth between them rapidly in live performance or while improvising.
