The SLOOP command is used to set repeat playback mode. The command can be input for each channel.
The SLOOP command allows specifying multiple channels at one time. Setting any bit(s) from CH0 to CH3 to
“1” repeats playback on the corresponding channel(s). Input the SLOOP command with each NCR set to a ”H”
level.
Channel settings
Channel
CH0
Setting this bit to “1” repeats playback on channel 0.
CH1
Setting this bit to “1” repeats playback on channel 1.
CH2
Setting this bit to “1” repeats playback on channel 2.

Be sure to set the channel setting bits( CH0-CH3).
Once repeat playback mode is set, the current phrase is repeatedly played until the repeat playback setting is
released by the SLOOP command or until playback is stopped by the STOP command. In the case of a phrase
that was edited using the edit function, the edited phrase is repeatedly played. Following shows the SLOOP
command input timing.
Effective Range of SLOOP Command Input
The SLOOP command is only enabled during playback. After the PLAY command is input, input the SLOOP
command within 10 ms (t
cm
) after the NCR signal on the target channel goes “H”. This will enable the SLOOP
command, so that repeat playback will be carried out. The NCR signal remains “L” during repeat playback
mode.
