Synchronization
Considerations
Adjusting for Latency
Latency compensation.
Because of the latency problem described on page 282, you might need to ad-
just Reason’s playback in relation to the sync master, so that they are in perfect
time. The tempo will not differ between the two, but Reason might play ahead or
behind the other application. You might need to adjust this. However, this is
something you only need to do once. The setting is stored with your other pref-
erences, so you don’t need to adjust it again.
Proceed as follows:
1. Set up the other application so that it generates a solid click, on for
example quarter or eighth notes, preferably with a special sound on
the downbeat.
This click can either come from an internal metronome or from a MIDI
source. If you use a MIDI source, make sure you pick one that has solid MIDI
timing.
2. Set up Reason so that it plays a similar rhythm as the other applica-
tion.
You might for example use the Metronome or Redrum drum computer for
this.
3. Start the two applications in sync.
4. Make sure you hear both applications at approximately equal level.
5. Open the Preferences dialog in Reason and select the Audio page.
6. Trim the “Latency compensation” setting until the “clicks” from the
both sources sound at exactly the same time.
7. Close the Preferences dialog in Reason.
