Yamaha DGX "portable grand" is the most playful yamaha keyboard for different melodies and world styles. Enjoy using it.
Q :When the instrument is turned on or off, a popping sound is temporarily produced.
A: This is normal and indicates that the instrument is receiving electrical power.
Q: When using a mobile phone, noise is produced.
A: Using a mobile phone in close proximity to the instrument may produce interference. To prevent this, turn off the mobile phone or use it further away from the instrument.
Q: There is no sound even when the keyboard is played or when a song or style is being played back.
A: Check that nothing is connected to the PHONES/OUTPUT jack on the rear panel. When a set of headphones is plugged into this jack, no sound is output.
A: Check the Local Control on/off.
Q: Playing keys in the right hand area of the keyboard does not produce any sound.
A: When using the Dictionary function, the keys in the right hand area are used only for entering the chord root and type.
Q: The volume is too soft.
Q: The sound quality is poor.
Q: The rhythm stops unexpectedly or will not play.
Q: The recorded data of the song, etc. does not play correctly.
Q: The LCD display suddenly goes dark, and all panel settings are reset.
A: The batteries are low or dead. Replace all six batteries with completely new ones, or use the optional AC adaptor.
Q: The style or song does not play back when the [START/STOP] button is pressed.
A: Is External Clock set to ON? Make sure External Clock is set to OFF.
Q: The style does not sound properly.
A: Make sure that the Style Volume is set to an appropriate level.
A: Is the split point set at an appropriate key for the cords you are playing? Set the split point at an appropriate key. Is the "ACMP ON" indicator showing in the display? If it is not showing press the [ACMP ON/OFF] button so that it does show.
Q: No rhythm accompaniment plays when the [STAT/STOP] button is pressed after selecting style number 121 or a style between 133-150 (pianist).
A: This is not a malfunction. Style number 121 and style numbers 133-150 have no rhythm parts, so no rhythm will play. The other parts will begin playing when you play a chord in the accompaniment range of the keyboard if style playback is turned on.
Q: Not all of the voices seem to sound, or the sound seems to be cut off.
A: The instrument is polyphonic up to a maximum of 32 notes. If the Dual voice or Split voice is being used and a style or song is playing back at the same time, some notes / sounds may be omitted (or "stolen") from the accompaniment or song.
Q:The footswitch (for sustain) seems to produce the opposite effect. For example, pressing the footswitch cuts off the sound and releasing it sustains the sound.
A: The polarity of the footswitch is reversed. Make sure that the footswitch plug is properly connected to the SUSTAIN jack before turning on the power.
Q: The sound of the voice changes from note to note.
A: This is normal. The AWM tone generation method uses multiple recordings (samples) of an instrument across the range of the keyboard; thus, the actual sound of the voice may be slightly different from note to note.
Q: The wrong notes sound when the keyboard is played.
A: Perhaps the performance assistant technology is turned on. Press the [PERFORMANCE ASSISTANT] button to turn it off.
Q: The ACMP ON indicator does not appear when the [ACMP ON/OFF] button is pressed.
A: Is the [STYLE] button lit? Always press the [STYLE] button first when you are going to use any style-related function.
Q: There is no harmony sound.
A: The harmony effects (01-26) behave differently according to their type. Types 01-05 function when style playback is on, chords are played in the accompaniment range of the keyboard, and a melody is played in the right-hand range. Types 06-26 will function whether style playback is on or off. For types 06-12 you need to play two notes at the same time.
