# orx-midi

MIDI support for keyboards and controllers. Send and receive note and control change events.
Bind inputs to variables.

Orx-midi is a wrapper around `javax.midi`.

## Usage

```kotlin

// -- list all midi devices
listMidiDevices().forEach {
    println("${it.name}, ${it.vendor} r:${it.receive} t:${it.transmit}")
}

// -- open a midi controller and listen for control changes
val dev = openMidiDevice("BCR2000 [hw:2,0,0]")
dev.controlChanged.listen {
    println("${it.channel} ${it.control} ${it.value}")
}

// or program changes
dev.programChange.listen {
    println("${it.channel} ${it.program}")
}
```
