It all started out with [url="http://www.youtube.com/watch?v=ijSQ9-HjoAA&feature=sdig&et=1253877080.6"]this video[/url], which you will either get with or without my explanation. The video also gives a slight introduction into [url="http://www.celemony.com/cms/index.php?id=products_plugin"]Melodyne[/url], so I won't dabble too much into that.

Now, sequencing isn't new. It's been around for a long time and before that there was a lot of things that could be done in the editing and recording room. The recently deceased Paul 'Les Paul' invented multitrack recording, which gave editors some measure control over the music since the 60's. Today, with either digital instruments or prerecorded samples and a good deal of synthesizing, you can do a lot too.
So how is this new program different? It's never been possible to access every single note on a 'normally' recorded piece of music. This program identifies notes, keys, the individual pitch, loudness and velocity of notes all at the same time, out of what up until now has always been a raw, unworkable stream of wavelengths. It's never been possible to do something so absolute in post-production.
Of course, all of this is of no use to anyone who wants to play live.

At present, this program is already causing a revolution in the music industry. So what does this mean for the future? In the demonstration video, you can see that the program actually processes Jeff's music faster than he can play. Theoretically it should be possible to correct notes just after he pays them as well. Of course, only a Jedi could do that.
Seriously, take another look at the beginning of that video. As Jeff points out, the program already has code that detects the key (the tuning all tones are subject to in any music piece) the piece is played in. Given enough time someone will also develop code that detects the type of music and the style it is being played in. And when you take that line of thought far enough, someone will eventually write a program that will simply correct you as you play your instrument.
All in all I think we're looking at the Guitar Hero of 2015 or so. :laugh:
