The Tone will not sound while the key is 
being pressed, but will sound after the 
Delay Time when the key is released.

The Tone will not sound while the key is 
being pressed, but will sound after the 
Delay Time when the key is released. 
However for this setting, the TVA envelope 
of the Tone will begin when the key is 
pressed, so in most cases only the decay 
portion of the sound will be heard.

If you select a Wave with tempo (BPM) 
being displayed, the Tone will synchronize 
to the tempo clock of the system regardless 
of which key is pressed. This is most 
effective when playing phrase loops in sync 
with the tempo of a song (p. 130).
If you want to sync to the tempo of a system 
in Patch mode, set the Source parameter 
(PATCH/COMMON/PATCH CLOCK) to 
SYSTEM.
If you want to sync to the tempo of a system 
in Performance mode, set the Source 
parameter (PERFORM/COMMON/
PERFORM CLOCK) to SYSTEM.

Specify the time after when the Tone will sound when using 
Tone Delay.
If PLAYMATE has been selected in Tone Delay mode, a 
setting of 64 will mean that the delay time will be set to the 
interval between the previous Note On and the current Note 
On. A setting of 127 will result in a time that is twice as long 
as for a setting of 64, and a setting of 32 will result in a time 
that is 1/2 as long.
If the Tone Delay Mode is set to CLOCK-SYNC, the setting 
will be in quarter-note steps, and the corresponding note 
value symbol will also be displayed. This lets you specify the 
delay time in note lengths relative to the synchronization 
tempo.
