Editing Song Position Markers This section covers two additional Marker-related features and details. For basic information on using the Markers for jump playback and loop playback, refer to the Owner's Manual.  Jump Markers The Markers explained in the Owner's Manual are also called "Jump Markers." In the Event List of the System Exclusive data (page 83), they are indicated as "SPJ-01"-"SPJ-04." In the Event List, they can be moved freely to other positions and can even copied to create identical Marker numbers at other positions. When the same Marker number is contained at different locations in the Song, the latest occurring one is used as a "Loop End Marker" (below).  Loop End Marker Loop End Markers can be used for putting additional Markers in Song data, providing even greater versatility. Creating a Loop End Marker is done within the Event List (and not on the Song Playback display), by simply copying one "SPJ" Jump Marker event to another position in the Song. The examples below show how Loop End Markers can be used in Song playback on the Song Playback display. Example 1 Copied within the Event List. Copied event becomes Loop End Marker Top of the End of the song song [SPJ-01] (1) [SPJ-01] [SPJ-02] (2) [SPJ-03] [SPJ-04] 5 (1) If the Song is playing back between the two SPJ-01 points, turning on [Loop] will result in a playback loop between those points. (2) If the Song is playing back between the second SPJ-01 and SPJ-02 and [Loop] is turned on, playback jumps back to the first SPJ-01 and loops between two SPJ-01 points. Example 2 Top of the song [SPJ-01] Copied within the Event List. Copied event becomes Loop End Marker [SPJ-02] [SPJ-01] [SPJ-03] [SPJ-04] (2) (2) (1) (3) End of the song MIDI Song Recording/Editing (1) If the Song is playing back between SPJ-02 and the second SPJ-01, turning on [Loop] will result in a playback loop between those points. (2) If [Loop] is turned on while the Song is playing back between the top of the Song and SPJ-02, playback will loop between SPJ-01 and SPJ-02. (3) If the Song is playing back between the second SPJ-01 and SPJ-03 and [Loop] is turned on, playback jumps back to SPJ-02 and loops between SPJ-02 and the second SPJ-01 (Loop End Marker). In the examples above, the actual data of the Loop End Marker is identical to the event it was copied from-only the location of the copied Marker provides it with this different function. In Song playback, the markers formatted as "SPJ-xxxxx" (xxxxx: any character except 01-04 and any number of letters is OK) are handled as Loop End Markers. Since the Event List in the MIDI Multi Recording function does not let you freely name Markers, the instructions above are recommended for creating new Markers. However, with sequence software on a computer, you can create new Markers and assign appropriate names to them. By naming Markers in this way, you can easily distinguish between Loop End Markers and Jump Markers in the Event List. NOTE Loop playback problems may occur if successive Markers are too close to one another. NOTE When the effect settings of the jump destination (the position you're jumping to) differ from those at the jump source, glitches or drop-outs in the sound may result. This is because of limitations in the effect processors of this instrument. NOTE When using the Guide function (page 65) with jump playback, keep in mind that the Guide indication may not be able to stay in time with the jumps. PSR-SX900/SX700 Reference Manual 85
