Advanced MIDI Device

This is opened by clicking the “ADVANCED MIDI” button on the Hardware Interface panel. The Advanced MIDI device is only used if you are controlling Reason Essentials from an external sequencer, using the External Control Bus inputs. Normally, you send MIDI to a track via the sequencer, by selecting the sequencer track.

You can select MIDI ports for up to four External Control Busses (on the Sync page in Preferences). Each bus can host 16 MIDI channels, for a total of up to 64 MIDI input channels. The Advanced MIDI Device is where you can route each MIDI channel to a specific device in the Reason Essentials rack:

1.	Select one of the External Control Busses by clicking the corresponding Bus Select button at the top of the Advanced MIDI device.

2.	Pull down the device pop-up menu for a MIDI channel and select a device.

The menu lists all devices in the current song.

Now, incoming MIDI data on the selected bus and MIDI channel is sent directly to the selected device, bypassing the Reason Essentials sequencer. The name of the device is shown in the name field for that MIDI particular channel.

3.	Try sending MIDI notes from the external sequencer, on the selected bus and MIDI channel.

The indicator below the channel's name field should light up.
