Changing Part Settings From An External Midi Device - Roland XV-5050 Owner's Manual

Changing Part Settings from
an External MIDI Device
By sending Control Change messages for different Part settings,
including volume, panning, and pitch, you can change these settings
remotely from an external MIDI device connected to the XV-5050.
This lets you control fade-ins and fade-outs, open and close filters,
and exercise other controls in realtime from the external MIDI
device.
The parameters that can be used for changing the settings, and the
Control Change messages that can be used to change the values, are
shown below.
* For more detailed information about Control Change messages, please
refer to "MIDI Implementation" p. 154).
* To change multi-effects, reverb, or chorus effects from an external
MIDI device, send a "System Exclusive message" (p. 157).
Remotely Controlling Volume (p. 154)
• Volume: Controller number 7
Remotely Controlling Stereo Positioning (p.
154)
• Panpot: Controller number 10
Remotely Applying Portamento (p. 154, p.
155)
• Portament: Controller number 65 (Portamento switch),
Controller number 5 (Portamento time)
Remotely Changing Sounds' Attack and
Release Time (p. 155)
• Release Time: Controller number 72
• Attack Time: Controller number 73
Remotely Changing the Cutoff Frequency (p.
155)
• Cutoff: Controller number 74
Remotely Changing Resonance (p. 155)
• Resonance: Controller number 71
Remotely Changing the Amount of Internal
Chorus/Reverb (p. 156)
• Effect 3 (Chorus Send Level): Controller number 93
• Effect 1 (Reverb Send Level): Controller number 91
Remotely Changing Pitch (p. 158)
• Coarse: Controller number 100 (value is 0), Controller number
101 (value is 2), Controller number 6 (value is 16–112)
• Fine: Controller number 100 (value is 0), Controller number 101
(value is 1), Controller number 6 (value is 32–96), Controller
number 38 (value is 0–127)
* When changing the Coarse parameter, set the amount of change in
pitch using Control Number 6 (Data Entry MSB) value. There is no
change in pitch when the value is set to "64." The pitch is raised as the
value increases from 64, and is lowered as the value decreases below 64.

Remotely Specifying the Range of Pitch Bend
(p. 156)
Procedure
1. Enable the external MIDI device to send a Control Change
2. Operate the external MIDI device — adjust its controls, play
* When changing the Fine parameter, set the amount of change in pitch
using Control Number 6 (Data Entry MSB) and Control Number 38
(Data Entry LSB) settings. There is no change in pitch when Data
Entry MSB is set to "64" and Data Entry LSB to "0." The pitch is
raised as the respective values increase, and lowered as the respective
values decrease.
• Bend Range: Controller number 100 (value is 0), Controller
number 101 (value is 0), Controller number 6 (value is 0–12)
message.
For example, if you want to change the volume level, set the
external MIDI device to send Control Number 7 (Volume
message). In this case, the MIDI channel is matched to the MIDI
channel of the Part whose volume you want to change.
* For information on how to set up your external MIDI controller, refer
to its owner's manual.
its sequencer, etc. — to send the desired MIDI messages.
* As sound changes occur, displayed parameter values reflect the changes
you make.
About RPN
"RPN" (Registered Parameter Number) is an extended MIDI
message activated by a previous Control Change message.
Use an RPN when you want to remotely change the XV-5050's
Pitch or Pitch Bend range settings. An RPN has an superior part
(RPN MSB) and a subordinate part (RPN LSB). The RPN MSB
(Control Number 101) informs the XV-5050 that an RPN setting
is to follow, and the RPN LSB (Control Number 100) value tells
the XV-5050 which parameter is to be set. Finally, a Data Entry
(Control Change 6) message sets the desired value.
Once the XV-5050 has received an RPN parameter, all further
Data Entry messages on that MIDI channel are applied to that
parameter. In order to prevent accidental changes, once the
desired setting has been made for the parameter, we
recommend that RPN be set to "Null."
For example, to raise the pitch of a certain Part by one half-step
(semitone) send the following Control Change message from
the external MIDI device.
• Controller number 100: value "0"
• Controller number 101: value "2"
• Controller number 6: value "65"
• Controller number 100: value "127" <- RPN null
• Controller number 101: value "127" <- RPN null
* For more detailed information about RPN messages, please refer
to "MIDI Implementation" (p. 154).
