Timers
SonicMood uses four types of
timers. The first type controls the note timing. That is,
the length of notes (sustain) and the space between notes
(pause). The second type measures elapsed time and (when
running) determines the time interval over which a Mood
plays (or a Picture displays) before going to another Mood
(or Picture). The third type is the sleep/wake timer that
controls when SonicMood goes to sleep or wakes up. Finally,
the fourth type will play a Mood at a specific day, hour,
minute, and second. There are actually a few other timers
running, but they control things like the scrolling of
messages and can't be changed by the user so we won't talk
about them here.
Note Timing
You can adjust the pause and
play time values for each instrument in a Mood from the
"Edit" window. Select "Edit Mood (Info)" (⌘I)
from the "Edit" menu (or click the "edit" button on the
toolbar) to open the window. Note timing is adjusted on the
"individual note properties" page. More information
specific to the editing of Moods can be found in the Help
Topic Mood Editing.
Mood and Picture
Timers
The Mood and Picture timers
operate in essentially the same way. What follows describes
both.

Each Mood or Picture can have its own time setting. You are adjusting the time interval for the item highlighted, unless you check the box labeled "Change All". The time for each is displayed in its list, next to the checkbox.
Another way to change the timer setting is by direct editing of the value displayed in the list. This works the same way as editing a Mood/Picture name. Highlight the item and use "select-pause-click" on the value, or select "Edit Highlighted Text" (⌘E) from the "Edit" menu or the contextual menu that appears when you right/control-click on the list.
While running, the timer displays a "progress bar". At the left of the bar is the elapsed time and at the right is the total time (both in mm:ss). The next Mood/Picture starts when the time has elapsed.
If a row is highlighted in the list, you can toggle its checkmark by pressing "⌥-spacebar".
Sleep and Wake
Timers
Selecting "Sleep Timer"
(⌘T)
or "Wake Timer" (⌥T),
or pressing the relevant toolbar button (if shown), will
drop down a sheet window where you can set a time of day
for SonicMood to pause (sleep) or resume (wake) playing.
When that time is reached, the volume will change slowly up
or down and after approximately one minute SonicMood will
pause or start playing, as appropriate.

To change a time setting click on a digit to select it, or use ← or → to move one digit. Use ↑ or ↓, click the up/down arrow buttons, or use the mouse wheel to change the highlighted value by one. You can also just type a new time in the appropriate places. You'll notice that the current digit is highlighted. You can use Tab and Shift-Tab to move between the three time entry fields.
Once a time is set the timer can be started by clicking the "On" radio button. To have the same event repeat, set a repeat time.
Click "Done" once the timer is set and running. The event time will be displayed under the timer's button.
Mood Scheduled Play
Timer
SonicMood will play a Mood at a
given time if it's been scheduled using the "Mood Scheduled
Play" timer. Like the "Wake Timer", if SonicMood is paused
it will "wake" to play the scheduled Mood, and stay awake.
Select "Mood Play Schedule" (⌘U)
from the Timers menu (or click the "Schedule" toolbar
button if displayed) to open the scheduling window.

To change a time setting click on a digit to select it, or use ← and → to move one digit back and forth. Use ↑ or ↓, click the up/down arrow buttons, or use the mouse wheel to change the highlighted value by one. You can also just type a new time in the appropriate places. You'll notice that the current digit is highlighted. You can use Tab and Shift-Tab to move between the three time entry fields and the schedule list.
Click "+" to make a new entry using the Mood in the "Play" menu, or click "Update" if you want to change the Mood highlighted in the schedule. Delete a highlighted schedule entry by clicking "-". To start the time of day timer, click the "On" radio button. If you need to, you can resize the window by dragging its “resize tab” at the lower right. To exit the window, click "Done"
In the Moods list you should see the time you've set for a Mood in the column "Schedule".
If the Mood timer (discussed in the "Mood and Picture Timers" topic above) is running when a Mood is scheduled, the Mood that's playing will pause and the scheduled Mood will start playing. While it's playing, the "progress bar" will increment up to the minimum time (“for at least” slider) the scheduled Mood was allocated. When that time is up, the previously playing Mood will resume. Note that “volume fade down” and “volume fade up” times are observed (“preferences” window, “general” page), so there may be a delay before the volume is back up and the “progress bar” starts to move again.
