# orx-midi
|
|
|
|
Basic MIDI support for keyboards and controllers. Send and receive note and control change events.
|
|
|
|
Orx-midi is a wrapper around javax.midi.
|
|
|
|
## Usage
|
|
|
|
```kotlin
|
|
|
|
// -- list all midi devices
|
|
MidiDeviceDescription.list().forEach {
|
|
println("${it.name}, ${it.vendor} r:${it.receive} t:${it.transmit}")
|
|
}
|
|
|
|
// -- open a midi controller and listen for control changes
|
|
val dev = MidiTransceiver.fromDeviceVendor("BCR2000 [hw:2,0,0]", "ALSA (http://www.alsa-project.org)")
|
|
dev.controlChanged.listen {
|
|
println("${it.channel} ${it.control} ${it.value}")
|
|
}
|
|
|
|
// or program changes
|
|
dev.programChange.listen {
|
|
println("${it.channel} ${it.program}")
|
|
}
|
|
```
