● Is the gain set too low? ( m Reference Guide : P. 12 [1-2. Gain, Minimum Velocity])
● Is the Utility mode’s [2-2. Trigger Bypass] bypass switch set to “ON”? ( m Reference Guide : P. 30)

produce sound when the pads are hit. ( m Reference Guide : P. 33 [3-6. Device Number, Local Control])
● Is the cable you are using OK?
The external tone generator does not produce sound.
● Is the MIDI cable (connector) properly connected? ( m P. 14)

Produces sound but the sensitivity is too low (volume is low).
● Is the gain set too low? ( m Reference Guide : P. 12 [1-2. Gain, Minimum Velocity])
● Pads with output or sensitivity control volumes should be adjusted (increased).
● Is the minimum velocity set too low? ( m Reference Guide : P. 12 [1-2. Gain, Minimum Velocity])
● Is a proper velocity curve being used? ( m Reference Guide : P. 13 [1-3. Velocity Curve])
● Is the volume of the voice you want to use too low? ( m Reference Guide : P. 18 [1-2. Volume, Pan])
● Is the drum head getting old?
● Change the INPUT ATTENUATION setting on the rear panel. ( m P. 9)
The trigger sound is not stable (for acoustic drums).
● Check the “Produces sound but the sensitivity is too low (volume is low).” list above.
● Is the proper pad type set? Select a larger pad type setting (DT snare m DT hi tom m DT lo tom m DT kick 1 m
DT kick 2) ( m Reference Guide : P. 12 [1-1. Pad Type])
● Is the DT20 properly attached with sticky tape? (Is there any old sticky tape remaining on the head?) ( m P. 13)
● Is the cable securely connected to the DT20 jack?
Double-triggers (when 2 sounds are played at the same time) are produced.
● Are you using a sensor made by a manufacturer other than Yamaha? If the signal is too large, double-triggers may
be produced.
● Is the head causing irregular vibrations? It may be necessary to mute the head.
● Is the sensor attached close to the center of the head? Move the sensor closer to the rim (above the bearing).
