206 Recording New Clips
The computer keyboard is, by default, activated as a pseudo-MIDI input device (page 174),
allowing you to record MIDI even if no MIDI controller hardware is currently available.
For every track, you can choose an input source other than the default: any mono or stereo ex-
ternal input, a specific MIDI channel from a specific MIDI-in device, audio from ReWire slave
programs or a signal coming from another track. The Routing chapter (page 171) describes
these options in detail.
16.2 Arming (Record-Enabling) Tracks
Track Arm Buttons in the Arrangement (Left) and Session (Right) Mixers.
To select a track for recording, click on its Arm button. It doesn’t matter if you click a track’s
Arm button in the Session View or in the Arrangement View, since the two share the same set of
tracks.
By default, armed tracks are monitored, meaning that their input is passed through their device
chain and to the output, so that you can listen to what is being recorded. This behavior is called
“auto-monitoring“ and you can change it to fit your needs (page 172).
If you are using a natively supported control surface, arming a MIDI track will automatically lock
this control surface to the instrument in the track (page 478).
Clicking one track’s Arm button unarms all other tracks unless the [CTRL](PC) / [CMD](Mac)
modifier is held. If multiple tracks are selected, clicking one of their Arm buttons will arm the
other tracks as well. Arming a track selects the track so you can readily access its devices in the
Device View.
