2C Program Change Filter in Global mode allows you to set how the X5DR responds to Program
Change messages. The options are ON (ENA), OFF (DIS), PRG (Program), and NUM (Number).
With the PRG setting, receiving Program Change messages on the Global MIDI Channel in
Combination Play mode will not select a Combination. The Combinations do not change. Only
the Programs of each Timbre are changed.
With the NUM setting, the X5DR ignores the Bank Select messages. This setting is used to
prevent the Bank from being changed when you are playing back performance data on the X5DR,
or when you are using a MIDI device that interprets the Bank Select messages in a different
manner than does the X5DR.
Pitch Bend
Pitch Bend messages [EnH,bb,mm] (bb:Lower digits of the value, mm:Upper digits of the value)
are used to shift pitch up or down. Note On messages determine the pitch (note or key) using the
note numbers in steps of a semitone. Therefore, if you wish to shift pitch in smaller steps, or if you
wish to create continuous changes in pitch, such as with trombone and guitar sounds, these
messages are useful. A total of 16384 steps are available by using the upper and lower digits
(bytes). The standard pitch (the pitch that exactly corresponds to the note number) is expressed by
8192 [bb,mm=00H,40H].
• How to set the Pitch Bend value varies depending on the type of sequencer or sequencing
software. (For example, some use values –8192–0–8191). Refer to the manual that came with
your sequencer or sequencing software.
To control the X5DR from a MIDI keyboard, you need to operate a pitch bend controller. There
are many types of controllers, such as joysticks, wheels, and levers. Operating any one of these
allows you to shift the pitch up and down, and releasing it causes the pitch to return to the standard
level.
When you input Pitch Bend on your computer or sequencer, you can set it to any value. However,
make sure that you restore the standard pitch. Otherwise, the Pitch Bend setting will affect
subsequent performances.
The Joystick Pitch Bend parameter allows you to set the pitch bend range for each Program. This
pitch bend range can be set for each Track by Bnd in Multi mode. In Multi mode, you can also use
the RPN to set the bend range. In this case, send the RPN [BnH,65H,00H,64H,00H] (Controller
#101 set to 0, and Controller #100 set to 0), then send the Data Entry messages [BnH,06H,mm]
(Controller #06). “mm” represents the bend range. “0” is no pitch change, 2 is a whole step (two
semitones), and 12 is one octave (12 semitones). The X5DR allows you to set a negative bend
range value. (In this case, the pitch bend direction will be reversed.) However, you can set only a
positive value using the RPN.
After Touch
After Touch is function that changes tonal color when you play the keys, then press them down
further. After Touch messages transmit the intensity of this effect. There are two types of After
Touch messages: Channel Pressure [DnH,vv] (vv:Pressure value) which applies the After Touch
effect equally to all keys for each MIDI channel, and Polyphonic Key Pressure [AnH,kk,vv]
(kk:Note number, vv:Pressure value) which applies the After Touch effect to each key separately.
The X5DR receives only Channel Pressure messages. (In general, Polyphonic Key Pressure
messages are not used.)
The After Touch messages transmit only the pressure value. The settings on the receiving device
determine what type of effect is applied by the After Touch. You can set the After Touch effect in
Program Edit mode on the X5DR to change tonal brightness and add modulation.
The MIDI filter in Global mode allows you to set the After Touch On/Off. You can set the After
Touch On/Off for each Timbre in Combinations and for each Track in Multi mode setups.
