Examples of MidiDeviceProvider

javax.sound.midi.spi.MidiDeviceProvider
A {@code MidiDeviceProvider} is a factory or provider for a particular typeof MIDI device. This mechanism allows the implementation to determine how resources are managed in the creation and management of a device. @author Kara Kytle
