Shielding?
It makes sense. Music is computerized now. It can do simulations, recording, and editing. Why even have a synthesizer when a computer can do everything?
Here's the real question: why are we still using a 30 year old software language for music (MIDI)?
MIDI (Musical Instrument Digital Interface), pronounced /ˈmɪdi/, is an industry-standard protocol defined in 1982[1] that enables electronic musical instruments such as keyboard controllers, computers, and other electronic equipment to communicate, control, and synchronize with each other. MIDI allows computers, synthesizers, MIDI controllers, sound cards, samplers and drum machines to control one another, and to exchange system data. MIDI does not transmit an audio signal or media — it transmits "event messages" such as the pitch and intensity of musical notes to play, control signals for parameters such as volume, vibrato and panning, cues, and clock signals to set the tempo. As an electronic protocol, it is notable for its widespread adoption throughout the music industry.
HD Protocol
Development of a version of MIDI for new products which is fully backward compatible is now under discussion in the MMA. First announced as "HD-MIDI" in 2005 and tentatively called "HD Protocol" since 2008, this new standard would support modern high-speed transports, provide greater range and/or resolution in data values, increase the number of Channels, and support the future introduction of entirely new kinds of messages. Representatives from all sizes and types of companies are involved, from the smallest speciality show control operations to the largest musical equipment manufacturers. No technical details or projected completion dates have been announced.[6][7] Various transports have been proposed for use for the HD-Protocol physical layer, including a call for ACN to be used as the sole or primary transport in show control environments.
