Orinj version 7.0.0
The MIDI roll view allows you to create MIDI files. With MIDI, you can create sound pieces for instruments that you do not have or cannot play. MIDI files can be inserted in your session or converted to wave and then inserted into your session.
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:
- You can build MIDI files by drawing the notes that these files should play. You can draw notes for the standard 128 MIDI instruments.
- You can play, pause, stop, fast forward, and rewind your MIDI file.
- You can record MIDI files into wave files that can then be inserted in your multitrack session.
- You can zoom in or out.
The MIDI roll view shows all MIDI files included in your multitrack session in addition to any other MIDI that you may have opened.
If you make changes in this view to the MIDI files included in your session, these changes will automatically be reflected in the corresponding MIDI files in the session.
MIDI roll menu
See Orinj MIDI roll menu. The menu is at the top of Orinj. It contains the commands that allow you to perform the tasks listed above.
Marker line, time line, time signature line, and MIDI control line
These are the four panels under the menu.
- Use the marker line to add markers at various points in your MIDI file with comments about your file. (Markers are treated as a standard MIDI market meta messages.)
- Use the time line to figure out where in your MIDI file you are (at what time position).
- Use the time signature line to similarly figure out where in your MIDI file you are (in terms of measures and beats).
- Use the MIDI control line to add various controls to your MIDI file – for volume, pan, instruments, and so on.
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.
MIDI instrument, channel, and track control panels
These are to the left of the MIDI track.
- Use the instrument control panel to select the instrument that will be played by the piano roll to the left of the MIDI track.
- Use the channel control panel to select which channels to show in the MIDI track.
- Use the track control panel to add tracks to your MIDI files and to view various properties for these tracks.
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.
Standard toolbars and panels
The following toolbars and panels are in all views of Orinj.
- Use the player toolbar to play, stop, pause, rewind, and fast forward.
- Use the zoom toolbar to zoom in and out of your file.
- Use the current time panel to see the current time (the position of the play cursor).
- Use the view toolbar to switch between the views of Orinj.
- Use the pointer toolbar to select the mouse pointers for various operations. Some pointers help you move objects, while others are designed for selection and drawing.
- Use the view times panel to see time information about your file, view, and selection.
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.
