Modifying Multi-Effects to Match 
the System’s Tempo
In the following example, we will synchronize the Step Rate 
parameter of STEP FLANGER to the system tempo.
1. Select the Patch 
PR-C: 094 Albion
 on the PATCH PLAY 
page.
This Patch uses STEP FLANGER as the Multi-effects 
type.
2. Set the Clock Source parameter (PATCH/COMMON/
3. Set the Step Rate parameter (PATCH/EFFECTS/PATCH 
MFX PRM) of each Tone to the beat length for the tempo 
you are synchronizing (p. 126).
4. Set the Clock Source parameter (SYSTEM/SETUP/
When the Clock Source parameter is set to MIDI, you can 
achieve synchronization with the tempo of an external 
MIDI device.
5. Try playing the keyboard while you change the System 
Tempo parameter (SYSTEM/SETUP/SYSTEM SETUP) 
to various values (p. 169).
You’ll notice that the tempo of the Patch’s modulation 
changes in accordance to the tempo clock of the XV-88’s 
system.
You can modify Multi-effects parameter values in time 
with a specified tempo or the tempo of an external MIDI 
device when you have selected the following values for 
the Type parameter of Multi-effects (PATCH/EFFECTS/
PATCH MFX TYPE).

Playing Phrase Loops in Sync 
with the System Tempo
Samples of drum, percussion, or other such phrases are 
called Phrase Loops. Normally, to play a Phrase Loop at an 
altered tempo, the pitch has to be adjusted. This is because of 
the nature of Phrase Loops, that is, when the tempo of a 
Phrase Loop is increased, the pitch rises, and the pitch falls 
when the tempo is decreased. To give an example, if a record 
is spun faster than normal, the pitch is higher than when 
normally played, and if spun more slowly than normal, the 
pitch is lower than when played normally. Such adjustments 
in pitch when playing a Phrase Loop at a changed tempo 
consumes a lot of time and effort.
Certain Patches on “SR-JV80-10: BASS&DRUMS” and other 
commercially available Wave Expansion Boards use Waves 
(Phrase Loops) for which the tempo (BPM) is indicated. With 
the XV-88, you can synchronize performances to a 
designated tempo in a Phrase Loop or the tempo set by an 
external MIDI device merely with a simple setting. Here, let’s 
synchronize a Phrase Loop to the System tempo.
