输出的大小MIDI Controlsblock is determined by theMIDI controlsandMIDI control numbersparameters.

The output data type is determined by theOutput modeparameter.

Data Type	Output Mode
`double`	`Normalized (0-1)`
`uint8`	`生MIDI (0 - 127)`

Parameters

expand all

`MIDI device`— MIDI control surface your block listens to
`Default`(default) |`Specify other`

To set the default MIDI device, use thesetpreffunction. For example, if the device is namedBCF2000, at the MATLAB command line, enter:

setpref('midi','DefaultDevice','BCF2000');

`MIDI device name`— Device name of MIDI control surface your block listens to
character vector

The MIDI device name is assigned by the device manufacturer or host operating system, and specified as a character vector. Usemidiid交互式identify your MIDI device.

To enable this parameter, setMIDI devicetoSpecify other.

`MIDI controls`— Specify if block responds to all controllers or specific controllers on MIDI surface
`Respond to any control`(default) |`Respond to specified controls`

This parameter also determines the size of the block output port. If you chooseRespond to any control, then the block output is a scalar corresponding to the value of the most recently manipulated control.

`MIDI control numbers`— Control numbers associated with MIDI surface controllers that your block responds to
`0`(default) | integer | array of integers

Usemidiid交互式identify the control numbers of your MIDI device. This parameter is available when you setMIDI controlstoRespond to specified controls.

`Initial values`— Control numbers associated with MIDI surface controllers that your block responds to
`0`(default) | scalar | array

If you specifyInitial valuesas a scalar, all controls specified byMIDI control numbersare assigned that value.

If you specifyInitial valuesas an array, the array must be the same size asMIDI control numbers.

`Send initial values to device at start`— Synchronize MIDI surface with values specified initial values
`off`(default) |`on`

选择该参数同步ize a MIDI device with values specified by theInitial valueswhen simulation starts. If your MIDI device can receive and respond to messages, it adjusts its controls as specified. This parameter is valid only whenMIDI controlsis set toRespond to specified controls.

Many MIDI devices are not bidirectional. Selecting this parameter with a unidirectional device has no effect. TheMIDI Controlsblock cannot tell whether a value is successfully sent to a device or even whether the device is bidirectional. If sending a value fails, no errors or warnings are generated.

`Output Mode`— Output mode for MIDI control value
`Normalized (0-1)`(default) |`生MIDI (0 - 127)`

Output mode for MIDI control value, specified asNormalized (0-1)or生MIDI (0 - 127).

Model Examples

Output Values from MIDI Control Surface

The example shows how to set the MIDI Controls block parameters to output control values from your MIDI device.

Open Model

Using a MIDI Control Surface to Interact with a Simulink Model

Use a MIDI control surface as a physical user interface to a Simulink® model, allowing you to use knobs, sliders and buttons to interact with that model. It can be used in Simulink as well as with generated code running on a workstation.

Direct Feedthrough	`no`
Multidimensional Signals	`no`
Variable-Size Signals	`no`
Zero-Crossing Detection	`no`

Tips

TheMIDI Controlsblock is not supported for rapid accelerator mode.

The executable generated from this block relies on prebuilt dynamic library files (.dll files) included with MATLAB. Use thepackNGofunction to package the code generated from this object and all the relevant files in a compressed zip file. Using this zip file, you can relocate, unpack, and rebuild your project in another development environment where MATLAB is not installed.
