10 The QY20 As A Tone Generator/ABC Expander
As an ABC Expander ————————————————————————
The QY20’s advanced ABC system can
also be controlled from an external keyboard,
making it useful as an ABC expander mod-
ule. Use the utility mode “ABC Zone” func-
tion (page 165) to specify the range of notes
in which you want the QY20 ABC system to
recognize chords. Then you can change ac-
companiment chords during song playback
simply by playing the appropriate chord in
the specified section of the keyboard. See the
“ABC Fingering Chart” in the Appendix
(page 179) for a list of the chords that can be
recognized by the QY20 ABC system.

If you place the cursor at the pattern number
or section name during song playback, you
can use the micro-keyboard section keys to
change sections as you play.
