Orinj version 9.0.0
Working with SoundFont files
Orinj uses SoundFont (sf2) files to play MIDI notes. See Orinj Working with MIDI files for more information.
Add a note
To add a note, click on the draw mouse pointer (
) in the pointer toolbar at the bottom of Orinj. Then click on the screen where you want to add the note.
The length of the note will be the length of the last note you added or changed.
The volume of the note will be the volume of the last note you added or changed. To match the MIDI protocol, Orinj uses velocity to specify volume (see MIDI Note on message for more information on velocity).
The instrument for the note will be the SoundFont instrument selected in the list of instruments on the left. Not all SoundFont instruments can play all notes. The note will be added only if the instrument can play it. You will get a message otherwise.
In MIDI, a note must be played on one of the 16 MIDI channels. Orinj places notes for the same instrument on the same MIDI channel. If a MIDI channel already uses the instrument, the note will be placed on that channel. If no channels use the instrument, Orinj will choose the first empty channel.
It is possible to place multiple instruments on a single channel in MIDI. Instrument controls in MIDI are separate from notes. If multiple instruments play on the same MIDI channel, there may be multiple instrument controls to choose the correct instrument for that channel before each MIDI note. Orinj avoids multiple instrument controls per channel by enforcing a single instrument per channel and placing the notes for that instrument in channels accordingly.
Notes in MIDI cannot overlap. You cannot play two of the same notes on the same instrument and the same MIDI channel at the same time. Orinj will adjust notes accordingly. If, for example, you add a note before another note, the new note may be shortened to avoid an overlap.
The length of MIDI notes also depends on MIDI ticks. The length of one MIDI tick in MIDI files created with Orinj is 9.375 milliseconds, defined by the Orinj MIDI clock and beat resolutions (see Orinj Audio formats). The start and end of all notes will be adjusted to fit accordingly. For example, you can add a note at 9.375 milliseconds from the beginning, but not at 9.4 milliseconds from the beginning.
You can also click on Note and then on Add in the menu. Choose the instrument, note, velocity, and start and end times of the note and click OK.
Move, stretch, or shorten a note
Use draw mouse pointer () or the move mouse pointer (
) at the bottom of Orinj to move, stretch, or shorten a note. Drag the ends of the note to stretch it or shorten it. Drag the middle of the note to move it.
You can also double-click on the note or click on the note to select it and then click on Note and then on Properties in the menu. Adjust the note, velocity, and start and end times and click OK in the dialog.
Remove a note
To remove a note, click on the note to select it. Then press the Del button or click on Note and then on Remove in the menu.
Change the instrument of a note
You cannot change the instrument for a single note. See Orinj MIDI channel control panel to change the instrument for a channel and all notes on that channel.
