To record notes for an instrument device - or for an external MIDI instrument - on a track in the sequencer, you need only create an instrument track as described in “Creating an instrument track”. The instrument track will automatically have Master Keyboard Input and the note lane will automatically be record enabled. Since you will only be recording MIDI events on the instrument track - and no audio - there is no need to adjust audio levels etc. These can always be adjusted afterwards.
Recording over or into an existing note clip will simply add new note events to the previously recorded events in the note clip as described in “Recording notes in Loop mode”. However, If the new recording should start before the original clip, and expand into the original clip, a new clip will be created and will engulf the original clip. Let’s have a look at the following example:
When using the “Alt” function in Loop mode, the clips between the locators will be muted - not the entire note lane. If the locators are placed over an existing clip, as in the example above, clicking the “Alt” button in Loop mode will split the clip and mute the clip between the locators.
