Many MIDI messages listed in the MIDI Data Format section, beginning on page 7, are expressed in hexadeci-
mal numbers. The chart below lists the corresponding decimal number for each hexadecimal number. (Hexa-
decimal numbers may include the letter “H” as a suffix.)

MIDI Messages Received by the DB50XG
The DB50XG is controlled by various types of incoming
MIDI messages which automatically determine play mode,
select MIDI channels, Voices and effects, change param-
eter values, and of course play the Voices specified for the
various Parts—complete with all the subtle nuances and
powerful dynamics of expression that the composer origi-
nally intended. Below is an explanation of the various types
of MIDI messages which the DB50XG can receive.

●
Key On/Key Off
Key On/Key Off messages, also called Note messages, tell
the DB50XG which notes to play, the Velocity value (de-
pending on how hard the keys are struck) at which to play
them, and how long to play them—i.e., when to start (On)
and stop (Off) playing each note.

●
Control Change
Control Change messages let you select a Voice bank, con-
trol volume, panning, modulation, portamento time, bright-
ness and various other controller parameters, through spe-
cific Control Change numbers which correspond to each
of the various parameters.

Program Change
Program Change messages tell the DB50XG which Voice
to select for each Part. You can insert Program Change
to select for each Part. You can insert Program Change
messages at any desired location in a song. Combining Bank
Select numbers let you select various Voices from the hun-
dreds of Voices available in the DB50XG.

Pitch Bend
Pitch Bend messages are continuous controller messages
that allow the pitch of designated notes to be raised or low-
ered by a specified amount over a specified duration.

System Exclusive messages control various functions of
the DB50XG, including master volume and master tuning,
play mode (XG or TG300B), effect type and various other
parameters specifically related to the DB50XG.
