SYNCHRONIZATION

130

ReWire users – Read This!

This chapter is about synchronization via MIDI Clock, and does not apply to users of

ReWire. If you are using Reason together with a ReWire compatible application, Re-

Wire automatically handles all synchronization issues for you. See page 123 for de-

tails.

What is Synchronization and

MIDI Clock?

Synchronization, in this context, is when you make Reason play at the same tempo as

another device; where both start, stop and can locate to certain positions, together.

This is done by transmitting MIDI Clock signals between Reason and the other de-

vice. MIDI Clock is a very fast “metronome” that can be transmitted in a MIDI cable. As

part of the MIDI Clock concept there are also instructions for Start, Stop and locating

to sixteenth note positions.

You can set up synchronization between Reason and hardware devices (tape record-

ers, drum machines, stand alone sequencers, workstations etc.) and other computer

programs running on the same or another computer.

Master/Slave

In a synchronized system there is always one master and one or more slaves. In our

case, the master is the one that controls the tempo. In other words, it is only the

tempo setting on the master device that is of any relevance, since the slaves slavishly

follow the master's tempo.

D Reason always acts as a slave. That is, it receives MIDI Clock signals, it

never transmits them.

! Before you create any serious projects that require sync, try out the fea-

tures described below and check out “Synchronization Considerations”

on page 117.

Slaving Reason to an

External Device

This example assumes that you have an external device, such as a drum machine,

hardware sequencer, another computer, tape recorder etc., that transmits MIDI Clock

signals to which you want to synchronize Reason.

1. Connect a the device via USB/MIDI to the computer running Reason.

2. Set up the other device so that it transmits MIDI Clock signals to the MIDI

Out you just connected to the computer running Reason.

3. In Reason, pull down the Edit menu (under Mac OS X, the Reason menu) and

open the Preferences dialog. Select the Advanced MIDI page.

4. Pull down the MIDI Clock Sync pop-up and select the MIDI Input to which you

connected the other device.

5. Close the dialog.

6. Activate MIDI Clock Sync from the Options menu in Reason.

This can also be set on the Transport panel.

7. Activate playback on the other device.

Reason will start playing ‘in sync’ with it and the Sync LED on the Transport will

light up.
