Reason can import standard MIDI files (SMF). This allows you to import MIDI data to Reason from other applications.
MIDI files have the extension ".mid".
If the imported MIDI file is of "Type 1", there will be one sequencer track for each track in the MIDI file.
If the imported MIDI file is of "Type 0" (that is, it contains one track with MIDI events on multiple channels), there will be one sequencer track for each used MIDI channel.
Any tempo changes in the MIDI file are disregarded.
The tempo in Reason will be set to the first tempo in the MIDI file.
The new tracks will not be connected to devices in the rack.
You will need to connect the tracks manually to the proper devices, by using the Out pop-up menu in the track list.
All controller data in the MIDI file is included.
This means that pitch bend, volume and modulation wheel data are preserved properly. However, some controllers may "mean" different things for the original MIDI instruments used when creating the MIDI file and the devices in Reason. When you have connected a sequencer track to a device, you may therefore need to remove some unwanted automation from the track.
