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.

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.

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 (tcm) 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.
