Beaming of Rests
The Staff view supports beaming of rests, a practice that is popular with
rhythmically complex music. Beam lengths are extended to include rests
that are integral parts of the beamed group of notes. Short stems, called
stemlets, extend from the beam toward the rest. This makes the
rhythms easier to read, because the beat boundaries are made clear.
Changing the Way Notes Are Displayed
Unlike musical notation programs, Pro Audio uses the MIDI events
themselves as the permanent representation of the music; thus, the
Staff view is only an interpretation of a MIDI performance.
MIDI notes do not always correspond exactly to notes on a staff. Whereas
a staff deÞnes precise grid-like starting times and durations for notes, a
MIDI note can start at any arbitrary time during the song, and last for
any length of time. If you record a performance from a MIDI keyboard,
for example, youÕll Þnd that some notes may start slightly before the
beat, and some a little after, and that the notes end a little late or a little
early. Although these slight imperfections are what gives a performance
its ÒhumanÓ quality, you donÕt necessarily want to see all these
imperfections notated with excruciating precision.
The Staff view has two options you can select to affect the way MIDI
notes are displayed on the staff:
HereÕs what the Staff view looks like with and without these options:
To Enable Beaming of Rests...
1. Click Layout button to open the Staff View Layout dialog
box.
2. Select the Beam Rests option.
3. Click OK.
Thereafter, the Staff view beams rests as though they were notes.
Option... Purpose...
Fill Durations Visually rounds up note durations to the next beat or
the next note, whichever comes first.
Trim Durations Visually rounds down note durations if they extend a
little way past the start of the next note.
