Screen 3: The Advanced MIDI panel of the Rack's Hardware Interface lets you patch incoming MIDI channels to devices. The other three synths are played by the three Arp/Sequencer tracks available on the keyboard. A Kong drum machine is patched to the KeyStep's Drum track on channel 10. The main screen shows the Rack I've set up for sequencing with an Arturia KeyStep Pro, which has four channels. There's often some overlap in device names, so be careful that you're routing to the right place. Note that Mix Channels modules are shown as well as instruments and effects (so that you can automate them from external CC sources). The pop-ups list every device in the Rack, and set the routing target for each incoming MIDI channel. The panel has four buttons for viewing the buses (MIDI Ports), with panes for the individual channels. Next, go to the Rack, scroll to the Hardware Interface at the very top, and show the Advanced MIDI panel (Screen 3). Simply choose MIDI ports from the pop-up lists next to each the four buses. These are chosen in the Sync tab of Reason's Preferences, under the External Control heading (Screen 2). Screen 2: Ports you want to appear in the MIDI Rack Interface are selected in the External Control section of the Sync Preferences.The direct MIDI routing system lets you elect up to four MIDI ports to appear on a virtual MIDI interface at the top of the Reason Rack. This method is great for connecting an external sequencer, or for using the Reason Rack purely as a multitimbral sound module. This is in line with how most DAWs work, but alongside this Reason has a separate direct MIDI routing system specifically for patching incoming MIDI channels directly to devices in the Rack.

Many MIDI controllers have predefined mapping schemes ('Remote Codecs') that Reason uses for this purpose. Controllers that you declare for Remote use (also in the Control Surfaces Preferences) can take advantage of fluid mapping of controls to Reason's devices. Reason has an intelligent MIDI control and mapping system called Remote. You'll find the device/port listed in Reason's Control Surfaces Preferences (Screen 1) under 'Easy MIDI Inputs'. Unless told otherwise, Reason assumes that a connected device should act like a master, and will direct all MIDI from it (regardless of channel) to whichever track or device is selected. Screen 1: The Control Surfaces preferences is where MIDI controllers are usually set up.Most Reason users connect a keyboard controller to play Reason's instruments, tweak controls and record MIDI parts into the Sequencer. This month we unpick some of the confusion around this to find the best ways to sequence and play Reason from external devices. Reason has two completely different systems for configuring MIDI sources. I'm increasingly turning to hardware sequencers to make my music, but even when I'm not using Reason as a DAW or plug‑in it's still my favourite sound module. We unpick some of the confusion around this to find the best ways to sequence and play Reason from external devices.
