1. About the sequencer block

• This block lets you create songs by recording/editing the
musical performance that is recorded from an external MIDI
device or from the controller block, and then plays back the
data, transmitting it to the tone generator block or to an ex-
ternal MIDI tone generator as MIDI messages.
• The sequencer block can be operated in two modes: Song
mode and Pattern mode.
• Using the Auto-Accompaniment function allows you to cre-
ate song efficiently by joining together patterns and phrases.
Patterns and phrases will be explained below.
• By recording one track at a time to create a multi-track re-
cording, you can create songs which use up to 32 tracks (up
to 48 tracks if you use the Auto-Accompaniment function).
• When songs or patterns are played back, the musical data is
output to the tone generator block and to the MIDI OUT
connectors. The output destination of the musical data can
be specified for each track by setting the Out Channel.
• “Tracks” are memory areas in which musical performances
are recorded. Musical data can be recorded, edited, and
played back independently for each track.

2. Auto-Accompaniment

• Auto-Accompaniment is a function that lets you specify
chords for the phrases or patterns created in Pattern mode,
creating an accompaniment that is played back automati-
cally.
• The accompaniment created using the Auto-Accompaniment
function consists of three types of elements: phrases, pat-
terns, and songs.
• “Phrases” are musical accompaniment phrases for a single
instrument, such as a rhythm pattern for the rhythm part, a
bass line for the bass part, or a chord backing for the guitar
part. Phrases are the smallest unit that makes up the accom-
paniment of a song.
• “Patterns” are created by joining two or more Phrases hori-
zontally, or by joining up to 16 parts vertically to create an
accompaniment with drums, bass, and chord backing. While
phrases contain musical data for a single instrument, pat-
terns combine two or more phrases to create a single back-
ing pattern. Patterns are the basic unit with which the ac-
companiment of a song is created.
• In order to create the accompaniment for an entire song,
you will need to create different patterns for the various
parts of the song, such as the intro, theme, fill-ins, breaks,
and ending.
• Song mode provides a Pattern track in which patterns can
be arranged, and a Chord track in which chords can be ar-
ranged. When you place patterns and chords in these tracks
as appropriate for the changes in your song, the accompani-
ment patterns will automatically be converted for playback
with the chords you specify.
