If knob and slider movements (MOTION) recorded in a pattern on the Roland JX-08 are not played back, “CC” in the sequencer menu may be set to “OFF”. When “CC” is “OFF”, MOTION is not recorded or played back. In sequencer mode, press the [MENU] button and set “CC” to “On”, then record the movements again if necessary.
For the detailed procedure, refer to “Making sequencer settings” in the JX-08 Reference Manual.
