just wondering.
people seem to rave a lot about live sequencing features, such as triggering a certain pattern with a key, or throwing in loops o the fly, for example.

i guess it's meant for live gigs, so the (computer-)musician has a bit more to do then just pressing the play button.

however i still don't really understand the sense of it.. one doesn't really change the arrangement of his song when playing live i guess? even with traditional handplayed instruments people usually stick to the pre-made songstructure... what's different when playing live are subtle variations.. but when triggering patterns, there are no such variations. so the result will be exactly the same as without such live features...?

or is that just me? would you change your songstructure on the fly while playing live? probably it depends on the style of music if it would work or not? i can imagine it would work with minimalistic/ repititive music.

I don't have any DJ experience, but it's about being interactive, I guess.

As far as real instruments are concerned, you can play the same song in different ways even if it's not a repetitive song. Knowing the scales would enable you to improvise in any kind song. In fact, I think only classical music musicians play a song as exactly it's written.

you mean something like, for example, making some harder and some more mellow patterns, and desciding on stage which one to trigger, according to the mood of the audience?

hm, i played guitar in a few bands some years ago, and yes, i did always improvise and change a riff a little bit (though not on stage), but the fun thing for me about that is how this comes spontaneously... if i had to program different versions before jamming it wouldn't be that fun.
but that's just me.
while thinking about it... i guess it could make composing (at home) a song more fun.

Yeah, something like that. But then again, I'm not a DJ, so someone else could better explain how to prepare materials and use them during the show...
