<p>Tempo and meter belong together. without both, there is no way to know where a beat lies in time.</p>
-<p>Tempo provides a musical pulse, which is divided into beats and bars by a meter.</p>

+When you change tempo or move an audio-locked meter, all objects on the timeline that are glued to bars and beats (locations, regions) will move in sympathy.</p>

+<p>Tempo can be adjusted in several ways:
<ul><li>by double clicking on a tempo marker.
this opens the tempo dialog which will allow you to enter the tempo directly into an entry box.
it is, however, a useful way to adjust the first tempo for a quick result.

If a tempo is locked to music, an entry will be available to lock it to audio.
Similarly an audio-locked tempo may be locked to music by right clicking it an selecting the "Lock to Music" entry.

-<p>Audio locked tempos stay in their frame position as their neigbours positions are altered. Their pulse (musical) position will change as their neighbours move.
-Music locked tempos move their frame position as their neighbours are moved, but keep their pulse position (they will move as the music is moved).

+<li>A ramped tempo increases its tempo over time so that when the next tempo section has arrived, the sesion tempo is the same as the second one.
this is useful for matching the session tempo to music which has been recorded without click tracks or electronic clocks.
Ramps may also be used as a compositional tool, but more on this later.
Note that a ramp requires two points - a start and an end tempo. The first tempo in a new session is ramped, but appears to be constant as it has no tempo to ramp to. It is only when you add a new tempo and adjust one of them that you will hear a ramp.
The same applies to the last tempo in the session - it will always appear to be constant until a new last tempo is added and changed.

<p>To add a new tempo, use the primary modifier and click on the tempo line at the desired position.

<h3>Techniques </h3>
<br>
-<p>As a general approach, the best way to control tempo ramps is to use them in pairs (disregarding the first one).

+<p>Lets imagine we want to match the click to a drum performance recorded in 'free time'.<br>
The first thing we need to do is determine where the first beat is. Drag the first meter to that position.
</p>
<p>Now the first click will be in time with the first beat. To get all the other beats to align, we listen to the drums
Drag the ruler so that 4|1|0 snaps to the 'phone' frame.

<p class="note">Notice what happened : The second tempo was changed.<br>
-You had set a musical position for the second tempo marker. It was not alignaed with the frame you wanted, so
+You had set a musical position for the second tempo marker. It was not aligned with the frame you wanted, so
you dragged the BBT ruler, making the second tempo provide enough pulses over the ramp for 4|1|0 to align with the desired frame.
</p>
<p>If your ramp doesn't feel correct, you may add more points within it and keep adjusting beat positions in a similar manner.
