MIDIPoet - Composer - Editing the events' properties

The following screen appears when an event in the diagram is chosen for esditing (by double-clicking it):

The screen's title indicates whether the current event modifies the properties of a text or image area, or the screen's background or drawing style.

If the current event modifies text or image, the modified areas must be specified. This is done by introducing the number of the area(s) in the field on top of the screen. If the event modifies a single area, its number must be entered here, whether it is a new area or a previously existing one. If the event modifies a range of areas, the lower and upper numbers of this range must be entered, separated by a hyphen. In the above sample screen, the event modifies image areas 2,3,4,5,6,7 and 8.

Areas must be specified starting from number 1.

The "Area(s)" field does not appear when modifying the properties of a screen background or drawing style event.

Below the "Area(s)" field, there is a checkbos labeled "Cyclic event". Putting a mark in this box will mean that the current event will occur repeatedly, and with a specific frequency. In this case, a field labeled "Frequency" appears to the right of the checkbox. This field can contain one of these values:
-- A numeric value, expressed in milliseconds, that indicates the event's frequency.
-- MIDI Tables. If the current event will be activated by a MIDI input, a resulting value containing a numeric value can be taken as the event's frequency.

If the "Cyclic event" chackbox is left unmarked, the event will occur only once.

There are two more checkboxes:

"Stop previous cycles" -- If this box is marked, the event will only serve to stop all of the specified area or areas' previous cycles.

"Deactivate" -- If this box is marked, the event will make the specified area or areas disappear from the screen.

If none of the above checkboxes is marked, the different attributes of the chosen areas can be modifies using the list that is below them.
These attributes depend on the type of the area or areas modified by the event.
An event can modify one or more attributes of the current area(s). The list that occupies the center of the screen specifies all the attributes that will be modified. To add or remove attributes from the list, use the "+" (add) or "-" (remove) buttons.

When an attribute is selected in this list, it can be changed using the "Attribute" and "Command" fields below the list.

The "Attribute" field is a drop-down list that lets you choose the attribute which will be modified.

In the "Command" field, you can specify the type of modification the current attribute will suffer. The available commands vary, depending on the current attribute.

Commands require different parameters that specify the values or ranges that will be used to modify the attribute of the area. Parameter specification varies according to the attribute and command, and can involve numeric values, numeric ranges (with or without an increment value), text values, names of images, fonts or drawing styles, or other sources from which a value will be taken (data lists, MIDI tables, MIDI ranges or other areas). To learn more about attributes, commands and parameters of the different areas, please check each of the area types' sections. (Text events ) (Image events) (Screen background events) (Drawing style events).

In the specific case of text events, when the "Text" attribute is selected, a checkbox labeled "Concatenate text" will appear at the bottom of the screen. Marking this box will make all of the text's contents events be acumulative (see Text events )

There are also MIDI output events. These events have their own special properties screen, which is explained in the MIDI output section
