Snapping to a minute while dragging a beat may result in some verly slow tempos.
Snapping a beat to a video frame however is an incredibly useful way to ensure your soundtrack is punchy and synchronised to the sample.

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.

-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).</p>

<p>A constant tempo will keep the sesion tempo constant until the next tempo section, at which time it will jump instantly to the next tempo.
these are mostly useful abrupt changes, and is the way in which traditional DAWs deal with tempo changes (abrupt jumps in tempo).</p>

-Meter positions beats using the musical pulse of a tempo, and groups them into bars using its number of divisions per bar.

<p>The first meter in a new session may be moved freely. It has an associated tempo which cannot be dragged by itself (although all others can).
It can be moved freely and is locked to audio.
</p>
That bar number cannot be changed, nor can tempo motion allow the previous bar to overlap.
If you need another bar, lock the meter to music again (right click->"Lock to Music"), drag the meter to the desired bar and re-lock to audio.
You may now drag your new bar freely again.

-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
Two bars later, place another new tempo.
</p>
Now while dragging any beat *after* the second new tempo, watch the drum audio and tempo lines until they align.
-<p>
+<p class="note">
Notice what is happeneing here: the tempo previous to your mouse pointer is being changed so that the beat you grabbed
aligns with the pointer.
Notice that the tempo lines previous to the changed one also move. This is because the previous tempo is ramping *to* the tempo you are changing.
<p>Holding down the constraint modifier, and with snap set to 'TC Frames', grab the BBT ruler just *after* 4|1|0.
Drag the ruler so that 4|1|0 snaps to the 'phone' frame.
</p>
-<p>Notice what happened : The second tempo was changed.

-<p>You had set a musical position for the second tempo marker. It was not alignaed with the frame you wanted, so
+<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 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.
