2. Close the Preferences window.
3. Select “Sync -> Send MIDI Clock” from the Options menu.
Now, you have set up Reason as a MIDI Clock sync master. When you start the Reason sequencer, MIDI Clock is
sent out on the selected MIDI Out Port.
D If your synced MIDI equipment is not in phase with the Reason sequencer, you might have to change the Out-
put Offset in the “MIDI clock sync” section on the Sync tab in Preferences.
D If the external MIDI equipment lags, set the Output Offset to a negative value.
A negative Output Offset means that the MIDI Clock signal is sent out from Reason earlier to compensate for the
lag.
D If the external MIDI equipment plays ahead of the Reason sequencer, set the Output Offset to a positive value.
There are also some additional options regarding the MIDI Clock signal that can be selected at the bottom of the
MIDI clock sync section:
• Send MIDI clock while sequencer is stopped.
When this box is checked, Reason continues to send out MIDI clock signal also when the sequencer is stopped.
• Send song position pointer.
When this box is checked, Reason sends out MIDI Song Position Pointer information to the slaved device. If the
sync slave device doesn't support Song Position Pointer, turning this setting off can improve synchronization. This
is also useful if the sync slave is playing a looped pattern and should disregard all positioning.
• Send stop/continue when repositioning.
When this box is checked, Reason sends out Stop/Song Position Pointer/Continue messages to the slaved de-
vice if the song position locator in the sequencer is moved (either manually or when in Loop mode) when the se-
quencer is running.
If unchecked, only Song Position Pointer messages are sent out if the song position locator is moved (or in Loop
mode) while the sequencer is running.
