MIDI Functions on the DTX
As mentioned above, MIDI messages can be divided into a channel message and a system message. The
following section describes the kind of data can be transmitted in these messages along with general MIDI
knowledge and explanations.
In order to transmit MIDI data from the DTX, it is necessary to set the various MIDI function parameters on
the display pages in Utility mode (P.112). Reference pages are indicated by each item to look for details on
how to operate or set each message.

Channel Message
You can transmit the following channel messages from or to the DTX. In order to transmit a channel
message, it is necessary to match the MIDI transmission channel (P.42, 92, 110, 118) of the DTX to channel
where the external MIDI device is connected.
Key Data
This data is the most important data concerning the performance of the DTX and in general these messages
are sent when a MIDI keyboard or synthesizer is played. It is also possible to send this data from an external
keyboard or sequencer and play the DTX. In the opposite manner, it is also possible to play a pad connected
to the DTX, a pattern or song and send these messages to play other external synthesizers.
Note On ........
Generated when a key is pressed.
Velocity ........
Shows how hard the key is struck.
Note Off ........
Generated when a key is released.
The DTX contains drum voices and keyboard voices. Each drum voice (drum or percussion sound) is assigned to MIDI
note numbers 0 to 127 and each keyboard voice is assigned to the half notes of MIDI note numbers 0 to 127. For
example, if you play an external MIDI keyboard and send the key data of note number 60, you will hear the drum voice
(drum or percussion sound) assigned to note number 60 on the DTX if it is a drum voice and note number 60 (or C3) if
it is a keyboard voice. Also, if you are sending key data from the DTX by playing a pad connected, you can also send
the note number data assigned to the input of the pad connected to an external device
To correctly send key data from the DTX is it necessary to match the MIDI send channel to the channel of the external
MIDI device on the 13th display page of Drum Kit Trigger Edit mode (P.42) Also, if you want to play a drum voice on
the DTX from an external MIDI keyboard, it is necessary to set the send channel of the external MIDI keyboard to 10.
Program Change
This data is used to switch the tone. When you switch a drum kit on the DTX, the numbers assigned to each
drum kit are sent. You can also switch the drum kit on the DTX by sending these messages from other
keyboards or sequencers.
In order to send program change data, it is necessary to assign the program change number on the 16th
display pages of Drum Kit Voice Edit mode (P.59). Also, in order to receive program change data, it is
necessary to set the parameter on the 15th display page of Utility mode to “receive” (P.118).
