BASIC CONCEPTS 4. Sequencer block 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 external 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 create 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 recording, 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. external MIDI device, MIDI tone generator external MIDI device, MIDI keyboard MIDI IN MIDI OUT Sequencer block Song Pattern Phrase Tone Generator block Effect block MIDI messages audio signals audio signals MIDI messages Controller block 1 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 automatically. • The accompaniment created using the Auto-Accompaniment function consists of three types of elements: phrases, patterns, 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 accompaniment of a song. • "Patterns" are created by joining two or more Phrases horizontally, 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, patterns combine two or more phrases to create a single backing pattern. Patterns are the basic unit with which the accompaniment 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 arranged. When you place patterns and chords in these tracks as appropriate for the changes in your song, the accompaniment patterns will automatically be converted for playback with the chords you specify.
