Scenic is a free software suite for streaming audio, video, and MIDI between live events. It was created at the Society for Arts and Technology (SAT) to give artists a powerful tool for telepresence in live arts contexts, and new media installations. The streaming is done over RTP with the GStreamer multimedia framework. Users can also choose low-bandwidth or high-quality codecs, depending on what is available on their system. It offers up to as many audio channels as your audio device supports. It consists of a desktop application and several command-line utilities: scenic (a Desktop application to stream audio, video, and MIDI over RTP); milhouse (streams audio and video over RTP); midistream (streams MIDI notes and controls over RTP); dc-ctl (controls connected DC IEEE 1394 cameras); firereset (resets an IEEE 1394 bus to help in case of problems); and jack-info (prints information about running JACK servers).
MIDI Sight Reader is an online music application (mupplet) inspired by its predecessor, the original MidiFlashCard system. The application scrolls both piano notes and guitar tablature. Notes are played for audio confirmation as they pass under the centerline on the window. The scrolling staffs drive a keyboard model and a guitar neck model. The guitar and keyboard can drive each other as well, for interactive exploration of the correspondence between the two instruments. The 3 components, staff, keyboard and guitar, can be independently added and removed from the top down, so many combinations of layout can be achieved.
