Sometimes I see technology as a wave, a wave as high as a mountain sweeping everything away in its path. The computer and software used in creating music is part of such a wave. At first, it's a novelty. "Wow, look what we can do! Create a whole section of violins, then add some drums!" And then some take it a step further, creating entire symphonies on a MIDI keyboard. The sounds of the early software sounds "synthetic" and not very real, even though the sounds may be actual samples of real instruments. But the "feel" isn't quite right. Then time goes by, and new technology comes up with modeled instruments. All the while people are experimenting with new ways to control the sounds - varieties of MIDI controllers evolve, guitars, horns, woodwind controllers. And the software continues to get better, more accurate, more under the feel and control of the player. And the computers get faster, more powerful. And then people develop software that actually composes music, from pattern recognition of evey piece of music ever written. Thus, you have a computer system with the entire history of music in its database, an ability to play in perfect pitch, and to combine and recombine patterns in infinite ways. In the very near future, there will be music contests, like the chess playing contests between the chess master and the computer, to see whether the computer can create and play a better piece than people.
Now, at this point, many of the real musicians and composers will freak out in dismay, and say "music is dead!" or fear for their jobs and such like. I think what may happen is that by being exposed to such a scenario, musicians and composers will be able to see "music" in a way they've never seen it before. Something like a total comprehension of how music has been created for the past several hundred years. The computerized system will mark the end of music as we know it, yes. But it will open a door to the real capability that only humans have - to actually "create" - to produce something "new". This is the point in the process that I look forward to.
