Creating a tempo map

Problem:
OK so you have a bunch of stems and you want to find the tempo of the
recording (without tapping your keyboard).

Pro Tools lets you do this by cutting a bar (usually drums) and
placing it at the zero point on a new track. It then has a tempo
marker which you place at the end of the clip. Presto magic, the tempo
of the song is displayed on the transport and you can set your grid to
match..

How do I do this in Cubase? Do I have to tap tempo the whole song to
make a tempo map? Is there no way for me to assess it's relative tempo
and then force the beats to match or drift as I see fit?

Thanks, CS

I think, what you´re looking for is called "Hit points" in Cubase, not
"tempo map". Look it up in the manual for further info, how it works...
I have tried to use it a few times, but didn´t really get to the point,
where I wanted to - probably cause I´m not a real MIDI guy.
Anyway, a friend saw a studio guy use hit points to detect a noticeably
unprecisely drum kit played live and then the MIDI timing (for various VSTi)
was adapted to the timing of the real drum kit.
How this is done exactly, I don´t know! But it was obviously possible in SX3
already!

If you can "slice" audio to stretch/trim it timewise, is also beyond my
experience. It is possible with C5, but I´m not sure about previous
versions.


Hope that helps at least a litte,

Phil

You want to use the Time Warp function.
Open the audio clip in the audio editor. Place the "S" line on the left
at the point where the clip starts. (If you can't see the S-line you
need to toggle "Show audio event").
Now go back to the project and drag the clip a little bit so that it
"snaps" to a bar line, let's say Bar 2. (supposing "snap" is on, "snap
type" is grid, and "grid type" is bar).

Go back to the audio editor. You will notice that the S-line now falls
on bar line 2. Now turn on Time Warp. Shift-click on the S-line. Drag
the appropriate bar line to the end of the clip, i.e. if the clip is 4
bars long, drag bar line 6 there (2 + 4 = 6).
If in doubt, turn on the click and check.
Now press CTRL-T to view the tempo map. You will notice that a tempo
event with the correct tempo has been inserted at the start of bar 2.
Map out the rest of the clip if necessary.

Does this help?

Thanks Phil...I'm not sure hit points will work for me here...I use
them all the time in Ableton Live to stretch timing and such but I'm
just trying to discover the tempo of an existing recording wihout
having to tap it on the mouse or keyboard (through the tempo detective
feature) and thus create the tempo map (grid lines on the quarter beat
of my particular tempo (e.g. 118.0034Bpm) to help me line up drum and
bass hits). I'll look up hit points in Cubase again, but I'm pretty
sure they don't identify the existing tempo of a track, they only
allow you to stretch to a different tempo (in loop creation mode). It
is a little frustrating because it is such a basic starting step and
Pro Tools makes it a no brainer...I'm surprise by it's absence. Thanks
for your help.

Cheers, CS
