Android 手机上的 USB MIDI 是做什么用的？怎么用 Android 手机上的 USB MIDI 是做什么用的？怎...

如果手机支持OTG，那么你可以通过OTG将键盘（这里的键盘是指作曲的键盘，类似电钢琴，但是他只是按键，没有音源）与手机连结，功能有两种，第一是用键盘在手机上弹奏作曲，第二是用手机作为MIDI设备在电脑上作曲弹奏。

一般是即插即用的。

你好楼主
usb midi键盘 , 相当于控制器，可以控制midi音源~
这个大概玩专业音乐,街头音乐弄的
你普通使用不用理会这东西,用不上的!

USB test: peripheral mode(这种模式下USB从设备是作为一个MIDI键盘！！)

Hardware needed: USB cable, OTG adapter
Android-to-Android
Apps needed: MidiKeyboard on Android device under test, MidiScope on another Android device.
Use Android devices as a peripheral controller for another Android device. To help test this mode, use another Android device running in host mode. Note that you could modify the test to work with a desktop computer running Digital Audio Workstation (DAW) software such as GarageBand.
Connect the USB cable to the Android device under test (Android device A).
Use an OTG adapter to connect the other end of the cable to a second Android device B that operates in host mode.
On Android device A:
Drag finger down from top of screen.
Select USB for Charging icon.
Select MIDI.
Launch MidiKeyboard app.
Select Android USB Peripheral Port from Receiver for Keys menu at top.
On Android device B:
Launch MidiScope app.
Select the other Android device as the source.
On Android device A:
Play notes on the keyboard and look for NoteOn and NoteOff on Android device B.

另外文章里还介绍了 MIDI 可以走 USB Host Mode/USB Peripheral Mode/BLE, 以及相应的测试方法.
