Figure 149. Tempo track.In the Tempo track, tempo changes appear as envelope nodes. Use the global tools to edit the tempo envelope. You create tempo changes by adding envelope nodes, then editing their values. You can draw, move, cut, copy, and paste tempo changes, create tempo curves, and edit tempo points in other ways.You edit the project’s tempo map the same way you edit automation envelopes. For information on general automation envelope operations, see Creating and editing automation envelopes.If you make a mistake using any of these tools, you can use Edit > Undo to correct the error.
To prevent the tempo map from being affected when you edit arranger sections, right-click the Tempo track and select Arranger Exclude.Before inserting a tempo change, decide if you want the tempo change to latch until the next tempo change, or only span a specific time range:
1. To insert a tempo change, do one of the following:
By default, tempo changes are inserted as envelope “jump” shapes. To change the curve type, right-click the envelope shape or click the rightmost column in the Tempo inspector. For details, see Adjusting the shape of a tempo change.
2. Select Edit > Copy or press CTRL+C.
4. Select Edit > Paste or press CTRL+V. The contents of the Clipboard are pasted from the insertion point, replacing any existing tempo events.You can also select Tempo Changes in the Cut Special (Edit > Cut Special), Copy Special (Edit > Copy Special), Paste Special (Edit > Paste Special), and Delete Special (Edit > Delete Special) dialog boxes to include/exclude tempo change events.To adjust an existing tempo change in the Tempo track, drag the envelope node or shape with the Smart tool , Move tool , or Edit tool .To enter a specific tempo numerically, right-click the envelope node and select Properties to open the Edit Node dialog box, then specify the desired BPM value and time position.To move multiple nodes, drag with the right mouse button to lasso select the desired nodes, then drag any of the selected nodes.When dragging an envelope node, the tooltip shows the current value and the delta value for the change.The mouse pointer informs you if you are moving a single node, multiple nodes, a line segment, or a time selection. The following table shows the various mouse cursors.
Table 5. Envelope mouse cursors
By default, when dragging tempo envelope nodes vertically, or using tap tempo or the BPM value field, tempos automatically snap to whole BPM values, without decimal points.To enable/disable whole value snapping, right-click in the Tempo track and select Snap Tempos To Whole Values.
3. By default, tempo changes are inserted as envelope “jump” shapes, which appear as a straight dotted envelope. Jump shapes produce an instant ninety degree jump where the envelope reaches the next tempo change.To change the tempo curve type, move the cursor over the segment of the envelope that lies between the two nodes until the Pencil cursor appears, then right-click the envelope and choose one of the following shapes on the pop-up menu:
Jump. This choice causes the envelope to make a ninety degree jump where the envelope reaches the second node. The tempo value continues until the next tempo change. Cakewalk displays jumps with a dotted line, meaning that there is automation data at the nodes where the dotted line begins and ends, but not where the line itself is.
Linear. This choice draws a straight line between the two nodes.
Fast Curve. This choice draws a curve between the two nodes that changes value rapidly at first, but more slowly toward the end of the curve.
Slow Curve. This choice draws a curve between the two nodes that changes value slowly at first, but more rapidly toward the end of the curve.You can also change the shape by clicking the rightmost column in the Tempo Inspector (see Modifying tempo properties in the Tempo Inspector).
To create a ramp, insert a new tempo node and drag the node above or below its neighboring envelope node.You can offset the tempo map, and thereby speed up or slow down the tempo, without losing the relationships between tempo changes. This is also referred to as “shelving” the envelope. You can raise/lower the entire tempo envelope, or only the selected time range.
2. Do one of the following:
Note: If the selected duration only spans a dotted envelope (Jump shape), you cannot position the pointer within selection to drag up/down. However, you can position the pointer above any tempo envelope node until the mouse pointer looks like this , then drag up/down.You can also quickly convert the selected dotted envelope range to a Linear shape. To do so, right-click the selected envelope region and select Add Nodes at Selection.This creates envelope nodes at the selection boundaries, and converts the region to a Linear shape.To offset the entire tempo map numerically, right-click in the Tempo track and select Offset Tempo Map, then specify a value to apply to all existing tempo changes. For details, see Offsetting the tempo map.To move an individual envelope shape vertically, including its start and end nodes, do one of the following:
2. Position the pointer over the envelope shape until the mouse pointer looks like this , then drag up/down.In a new song, the tempo may not be defined yet. If you don’t know the exact BPM value for your project, you can manually set the project tempo by tapping the mouse button.
2. Click the TAP button in the Tempo track repeatedly to tap out a tempo.Cakewalk averages the last 16 taps (weighted in favor of the last 4) to determine the correct tempo. The computed BPM value appears in the BPM textbox.
Tip: If you want to use the computer keyboard to tap, select Project > Insert Tempo Change to open the Tempo dialog box, then click the Click here to tap tempo button to give it focus, and tap with the SPACEBAR or ENTER key.If you want to use tap tempo during playback, first right-click the Tempo track and make sure Update BPM Display During Playback is disabled.To delete a tempo change, do one of the following:
Right-click an envelope node and select Delete Node.
To reset a tempo envelope node to its default value, do one of the following:
Right-click the node and select Reset Node.Double-clicking the first node will set the tempo to 120 BPM. Double-clicking any other nodes will set it to the project tempo (i.e. the first tempo entry).To reset the entire tempo map and clear all tempo changes, do one of the following:
Right-click the tempo envelope and select Clear All.
Right-click the Tempo track and select Reset Tempo Map.To show/hide BPM values on the tempo envelope, right-click the Tempo track and select Show Tempo Values on Envelope.
