Tempo and Meter Changes
Pro Tools transmits both Tempo and Meter data
to ReWire client applications, allowing ReWire-
compatible sequencers to follow any tempo and
meter changes in a Pro Tools session.
With the Pro Tools Conductor button selected,
Pro Tools always acts as the Tempo master, us-
ing the tempo map defined in its Tempo Ruler.
With the Pro Tools Conductor button dese-
lected, the ReWire client acts as the Tempo mas-
ter. In both cases, playback can be started or
stopped in either application.
Looping Playback
Because Pro Tools does not offer separate loop
markers as found in other third party applica-
tions such as Reason, if you want to loop play-
back, do one of the following:
To loop playback in Pro Tools:
1 In the Pro Tools Time Line, select the time
range that you want to loop.
2 Begin playback by pressing the Spacebar or
clicking the Transport’s Play button.
To loop playback within a ReWire client sequencer
■ With playback stopped, specify the loop
within the ReWire client application and begin
playback.
Automating ReWire
ReWire supports automation for switching in-
puts during playback.
To automate switching inputs during playback:
1 Set the track’s automation to write.
2 Change the input link pop-up menu manu-
ally.
– or –
Draw the automation in the Edit window.
Pro Tools supports tempo values from
30–300 bpm. When slaved to a ReWire cli-
ent application, Pro Tools playback will be
restricted to this range even if the client ap-
plication’s tempo is outside this range. Ad-
ditionally, some ReWire client applications
(such as Reason) may misinterpret
Pro Tools meter changes, resulting in mis-
matched locate points and other unexpected
behavior. To prevent this, avoid using meter
changes in Pro Tools when using Reason as
a ReWire client.
If you create a playback loop by making a
selection in the Pro Tools Time Line, once
playback is started, any changes made to
loop or playback markers within the Re-
Wire client application will deselect the
Pro Tools Time Line selection and remove
the loop.

tion, see the Pro Tools Reference Guide.
