Troubleshooting

No sound? Wrong sound? When a problem like this occurs, please check the following points before assuming that

the product is faulty. In many cases you’ll find the solution to your problem here. If the problem persists, then contact

your Yamaha dealer or service center (Page 91).

No sound.

•Is the power of the MOTIF-RACK and any external equipment connected to the MOTIF-RACK turned on? (Page 14)
•Have you made all the appropriate level settings – including the Master Volume on the MOTIF-RACK and the volume
settings on any connected external equipment? (Page
14
)
• Is the MOTIF-RACK properly connected to related external equipment (e.g., amplifier or speaker) via audio cables?
(Page
15
)
•When the voice produces no sound, is the volume in the Voice common edit set appropriately? (Ref. #33)
• When the voice produces no sound, are the parameters in the Voice element edit (e.g., level, element switch, note limit,
velocity limit) set appropriately? (Page 38)
• When the voice produces no sound, are the effect and filter settings appropriate? (Inappropriate filter cutoff frequency
settings can result in no sound.) (Pages 39, 41)
• When the multi produces no sound, has a voice been assigned to each part? (Ref. #20, #26)
• When the multi produces no sound, is the note limit of each part set appropriately? (Ref. #22)
• When the multi produces no sound, is the volume of each part set appropriately? (Ref. #33)
• When the multi produces no sound, is the output select of each part set appropriately? (Ref. #96)
• When the multi produces no sound, are any or all of the parts muted? (Page 38)
• When the multi produces no sound, are the receive channel of each part set appropriately? (Ref. #32)
• When the arpeggio produces no sound, are the note limit and velocity limit set appropriately? (Ref. #66, #67)

Distorted sound.

• Are the effect settings appropriate? (Ref. #162-#174)
• Are the filter settings appropriate? (Excessively high filter resonance settings can cause distortion.) (Ref. #76-#79)
• Is the VOLUME set so high that clipping is occurring? (Page
14
)
• Is the volume of each element in the Voice mode or the volume of each part in the Multi mode set too high? (Ref. #33,
#111)

Sound level is too low.

• Are the MIDI volume or MIDI expression settings too low? (Page 78)
• Is the cutoff frequency of the filters set too high/low? (Ref. #76, #81)

Sound is cut off.

• Are you exceeding the maximum polyphony of the MOTIF-RACK? (Page 20)
