Thirdly, it contains an audio amplification section for the output of the various tones produced by the sound module section. This output section may contain a pre-amplifier only with no internal speakers and audio output jacks which can be connected to any sound system. MIDI was, and still is, the most viable system for music recording production using the minimum involvement of personnel. Almost all CD's, cassettes, DAT's and live performances, concerts, and most television commercials are produced using MIDI to some extent. Of course, this also assumes that the playback amplification is of equal value to the original audio system used to master the recording.
Most sound cards sound like a cat mugging a canary in Central Park.
These include most karioke files and the various software proprietary file producers. Most of them are excellently done and the musicianship is extraordinary. Commercial recordings, on the other hand, are not always produced in General MIDI because of some limitations imposed by that system. The first sequencers were very complicated and rarely could the keyboard player operate both the keyboard and the recording device at the same time. General MIDI was an excellent answer to the problem of the various sound modules and keyboards not having instruments in defined locations for easy access on playback.
