I haven't heard 'searching', but changing the tempo isn't really a good idea!

Now, if you absolutely want to do that, there are ways. I don't know what sequencer you are using, but, for example, in Cubase, you'd have to use the master track to set up your tempo changes.

However, as I'd be willing to bet (without even hearing the track), coast 2 coast never actually changed the tempo. What they probably did was just adjust the note lengths. If you're at 140 bpm, keep your track at 140, but make each quarter note a half note, each eigth note a quarter note, etc. That'll get you to 70 bpm.

I see what you mean, but how can I smoothly increase the track from 70 to 140 ??

I use Reason 2 and Cubase 5.1 (And a notecomposer called Musicator)

In cubase, click "Project -> Tempo track". The effect you want is easy enough to do.

i don't know, but i think i remember mauro doing this in some song...i would think that all you would need to do is make a melody, and then pitch bend it down to the desired bpm and the back up...i don't know really though...

Sorry, I didn't realize that you wanted to change the tempo gradually. Yes, that would be quite difficult using the method I described

If you have fruity, would it not be possible to automate the tempo???

That might work, not sure...

Yes, it IS possible to automate track Tempo in Fruity, just like u can do to anything else. But just make sure that bfore u go playing with that, u set its initial tempo as default, so your track tempo wont go on the loose if u dont match the exact initial tempo after the automated process. Right-click it and turn on the option "start events in this position", or u can draw your automation line and click on the menu option "draw actual position" (or something like that, cant remember exactly), and just make the variation u want on that point whithout affecting the rest of the track.
Cant help with other sequencers, but the way to go should be pretty much the same...

Once i heard a very cool bangin track in some rave here, that after its energy peak, its tempo began to go down gradually and some strings rising and elements being added, until it stoped into a beautiful chilling breakdown, and then it rised again with full energy and the new elements rearranged after that (dont know which song is that), and it was so awesome (not to mention creative)!

Searching does utilize a tempo change rather than note changes, it's easy to tell because the percussion elements are affected as well not just melody notes.

You can also do this in the mastering process later on.
Like in WaveLab 4 for example:
Select the area you want to use, go to Process -> Pitch Bend and apply as much pitch bend as you feel like. The pitch goes down along with the tempo of the track.
I'm sure other programs have similar functions too.

Well, but this will make the song pitch to decrease as well and change the melody and the notes lenght... Although its a cool effect, its not the case of the song he mentioned, where just the tempo is tweaked, not the pitch

Pitch shifting is a bad idea, it's not the same as a tempo change.
