1-2 Selecting a rhythm pattern to use
The PS-04 incorporates a rhythm function that always operates in sync with the recorder. This function
can automatically repeat patterns that are several measures in length and contain drum sounds (drum
kit) and bass sounds (bass program). It is also possible to use a combination of patterns to form a longer
rhythm accompaniment (song). In this example, we will choose a simple pattern to use as guide rhythm
during recording.
1. Press the [RHYTHM] key.
The [RHYTHM] key lights up and the PS-04 switches to RHYTHM mode which lets you make
various rhythm related settings.
The rhythm function has two modes: PATTERN mode for repeatedly playing patterns, and SONG
mode for playing the rhythm accompaniment to an entire song. By repeatedly pressing the
[RHYTHM] key, you can switch between these modes.
When you first select RHYTHM mode, the PATTERN mode is active, and the name of the
currently selected pattern appears on the display.
2. Turn the dial to select the pattern you want to play.
The PS-04 has 511 pattern slots, of which 346 are preprogrammed. (The indication "EMPTY" is
shown instead of a pattern name for empty patterns.)
In this example, we will select pattern number 510 which plays a rim shot sound as a quarter note.
3. Press the [R/P] key.
The selected pattern starts to play, and the [RHYTHM] key flashes in sync with the current tempo.
While the pattern is playing, you can also switch to other patterns simply by turning the dial.
H INT
Immediately after creating a new project, the pattern playback volume will be set to zero.
To hear the rhythm play, you must raise the drum/bass monitor level.
