EXTERNAL MIDI INSTRUMENT

4. Play back the song and adjust the audio level on your external MIDI instrument and/or the audio interface
gain.
To be on the safe side, leave around 12dB of headroom below the clipping level (first yellow LED lit on the Input
Level Meter on the Audio Track):
q You might also have to move (or nudge) the MIDI clips on the External MIDI Instrument track back slightly to
compensate for any MIDI latency. Alternatively, you could slide all the notes in the clip back using the Re-
Groove Mixer, see “Using the ReGroove Mixer for MIDI latency compensation”.
q If you don’t want to adjust the MIDI notes beforehand to compensate for MIDI latency, you could move all Slice
Markers in the audio clip after recording (see the tip below) or try quantizing the audio clips.
MIDI latency mainly occurs in the MIDI interface and in the connected MIDI instruments and is nothing Reason can
automatically compensate for. Refer to “Moving clips” for more information.
5. Make sure the Audio Track is enabled for recording and then click Record in the sequencer to start recording
the audio from your MIDI instrument.
6. When you are finished with the audio recording, click Play to play back the recorded audio.
! If you are monitoring your external instrument externally, you will want to mute the External MIDI Instrument
track so that you don’t get double notes or phasing problems during playback.
If you are monitoring your external instrument only internally in Reason, there is no need to mute the External MIDI
Instrument track. During playback, the monitor function on the audio track is automatically disabled, and only the
recorded audio on the audio track is output.
q If you are experiencing problems with MIDI latency, i.e. the audio is recorded a little late in the audio clips, a
good thing to try is to quantize the audio clips after recording, see “Quantizing audio”.
