Advanced MIDI - The External Control Bus inputs
About the External Control Bus inputs
The External Control Bus inputs allow you to receive MIDI from external equipment/applications directly to individual
Reason devices.
! MIDI control keyboards/surfaces should NOT be set up using the External Control Bus! Instead, set them up on
the MIDI tab, see “Preferences – MIDI”.
• These MIDI inputs are for controlling Reason devices from an external sequencer.
This could be an external hardware sequencer or a sequencer application running on another computer.
! Do NOT use the External Control Bus if you are only going to use Reason’s internal sequencer for recording
and playback!
You set up the External Control Bus inputs on the Sync tab in the Preferences dialog:
D Select a separate MIDI port for each bus you plan to use.
Each bus provides 16 MIDI channels, for a total of up to 64 MIDI input channels. For example, if you have an ex-
ternal sequencer with two MIDI outputs, you connect these to two MIDI inputs on your MIDI interface and select
these two inputs for the first two busses on the Advanced MIDI page. You will then be able to send MIDI on up to
32 channels from the external sequencer to Reason.
D Make sure you don’t select a MIDI port that is already selected on the Control surfaces tab (or in the MIDI
Clock Sync section).
q To control external MIDI equipment from Reason, you can use the MIDI Out Device. Refer to “MIDI Out Device”
for more details.
