Wave

WAVn

Sine, Other

Modulation waveform. Sine wave or other (“other” is the wave selected 
in the Wave Form Parameter above).

Phase

PHSn

Normal, Reverse

Phase of the delay

Tap

TAPn

0 to 100 %

The output time of the delay sound in regard to the time of the delay 
loop (see 

page 31

)

Speed

SPDn

0.0 to 10.0

Modulation speed (modulation phase if the band is synchronized with 
another band)

Depth

DPTn

0.0 to 10.0

Modulation depth

Pan

Delay level

Sync

SYNn

1 to 8

Setting to synchronize the modulation of different bands (set to any 
number other than the band number of the current band, it will syn-
chronize with that band. If set to the same number as the current band, 
it will not synchronize.)
