Editing tempo and signature
The Beat Calculator
The Beat Calculator is a tool for calculating the tempo of
freely recorded audio or MIDI material. It also allows you to
set the tempo by tapping.
Calculating the tempo of a recording
1. In the Project window, make a selection that covers an
exact number of beats of the recording.
2. Select “Beat Calculator…” from the Project menu.
The Beat Calculator window appears.
3. In the Beats field, enter the number of beats that the
selection encompasses.
The corresponding tempo is calculated and displayed in the BPM field.
• If you need to adjust the selection, you can go back to
the Project window, leaving the Beat Calculator open.
To re-calculate the tempo after adjusting the selection, click Refresh.
4. You can also insert the calculated tempo into the
tempo track by clicking one of the buttons in the lower left
corner of the Beat Calculator window.
Clicking “At Tempo Track Start” will adjust the first tempo curve point,
while “At Selection Start” will add a new tempo curve point at the selec
-
tion’s start position, using the “Jump” curve type (see “Adding tempo
curve points” on page 465).

rial, activate playback.

board or with the mouse button.

Action –
Insert Bars
When you select this action, clicking the Process button
will insert the specified number of empty bars with the set
time signature at the start position specified above.
Action –
Delete Bars

will delete the specified number of bars, beginning at the
start position specified above.
Action –
Reinterpret
Bars
When you select this action, clicking the Process button
will reinterpret the bar range to fit the specified time signa
-
ture. This is very special in the sense that both bars+beats
positions of the notes and the tempo are being changed to
fit the new time signature, but the playback of the notes will
stay just the same.
For example, if you want to reinterpret a bar with the time
signature 3/4 so that it gets the time signature 4/4, quarter
notes will become half note triplets. If you reinterpret a bar
with the time signature 4/4 to attain 3/4, you will get qua
-
druplets.
Action –
Replace Bars
When you select this action, clicking the Process button
will cause the time signature of the specified bar range to
be replaced by the one you specify in this dialog.
Action –
Signature
This lets you specify the time signature for the action you
select on the Action pop-up menu (except for the Delete
Bars action).
Process Click on this button to apply your changes to the speci-
fied bar range.
Close Clicking this button without clicking on “Process” first will
close the dialog without applying your settings.
