PATTERN Mode ——————————————————————————
1The QY20: What It Is & What It Can Do
2. The accompaniment tracks feature Yamaha’s advanced ABC
(Auto Bass Chord) auto-accompaniment system ( page 47).
Of course, you can create accompaniments without using ABC
if you like.
The QY20 PATTERN mode produces the accompaniment patterns
that are used by the SONG mode accompaniment tracks. 100 preset
patterns are provided (each with 6 variations: Intro, Normal, Varia-
tion, Fill-in 1, Fill-in 2, and Ending) that you can simply select and
use to create accompaniments in a wide variety of styles ( page 42).
In the PATTERN mode you can also record entirely original patterns
that you’ll later string together in the SONG mode to create a com-
plete accompaniment track ( page 52). The ABC auto-accompani-
ment feature can be applied to your own patterns. The QY20 can store
up to 100 original patterns, and you can use the MIDI bulk dump util-
ity to transmit pattern data to a MIDI data recorder such as the
Yamaha MDF2 if you want extra storage capacity ( page 163).

See the Appendix (page 178) for a complete list of the preset patterns.
