  nmj - Network MIDI for Android™ & desktop Java

humatic - htools
nmj is a pure Java MIDI over ethernet solution for Android™ and desktop Java on all major operating systems, compatible with
  • RTP MIDI (as specified in RFC 4695 and implemented in Apple's Network MIDI in OS X)
  • ipMIDI (and other "raw" solutions like Midi2Net)
nmj provides a user defineable number of multi- or unicast raw or RTP MIDI channels and is fully configureable through a simple java api or an included control panel

The desktop version implements Java's service provider architecture for MIDI devices and will let java applications and applets access all configured network MIDI channels soon as the library has been put onto the classpath. There are no additional installations required and no native libraries involved.

As javax.sound is not implemented on Android, a small public api has been added that makes the underlying architecture accessible with little coding effort, enabling creation of standards compliant MIDI over Wifi applications for Android devices.

The library supports multicast DNS service discovery for zero configuration MIDI networking with OS X or rtpMIDI hosts and brings default configuration settings that will let it instantly work with ipMIDI, another popular native MIDI over ethernet solution (available for Windows and OS X).
