The MIDI roll view allows you to create MIDI files and record these MIDI files to wave files that can then be inserted into your session. In this view, with the MIDI functionality, you can create tracks for instruments that you do not have or cannot play.
A portion of the MIDI roll view is shown on the picture below. To see this view (in case
you are looking at another view), click on View and then on MIDI Roll View in the
menu or click on the MIDI roll view button
()
of the view toolbar.
The following are examples of things you can do in the view:
See MIDI roll menu. The menu is at the top of Orinj. It contains the commands that allow you to perform the tasks listed above.
These are the four panels under the menu.
The MIDI track takes the largest portion of the view, under the MIDI control line. Use this track to draw the notes of your MIDI file. There is a piano roll to the left of the track. Use the piano to test the notes that you will draw in the track.
These are to the left of the MIDI track.
The vertical yellow line running through the MIDI track is the play cursor. This play cursor shows you where you are in your MIDI file. If you play your MIDI file, playback will start from the play cursor. The play cursor will move with the playback so that the notes being played will be the notes right under the play cursor.
Use the wave track to insert a wave file in the MIDI roll view. The wave file will then accompany the MIDI file during playback. This is useful if you want to confirm that the MIDI file has the right rhythm and tempo to be inserted later in your multitrack session. (See Working with waves in the MIDI roll view).
The following toolbars and panels are in all views of Orinj.
At the bottom of Orinj, you can see the label "CPU: 0%". This is the CPU usage bar. During playback, this bar shows you how strenuous playback and recording are on your computer.
