502 Chapter 20 Editing MIDI Events in the Transform Window
Global Parameters
These parameters globally affect the Transform window appearance and operating
mode.
 Mode menu: Choose one of the following settings menu options to determine how
events are transformed.
 Apply operations to selected events: Choose this mode to apply the operations to all
selected events. The selected events are determined by the selection conditions.
 Apply operations and delete unselected events: Choose this mode to transform the
selected events, and delete all non-selected events. Only events that match the
selection conditions will remain after the transform operation. This mode allows
you to use the Transform window as a programmable filter—where only events
that match the conditions survive.
 Delete selected events: Choose this mode to delete selected events. This mode
enables you to use the Transform window as a programmable erase function. All
events that match the conditions are deleted, and all other events remain
unchanged. The operation settings are irrelevant in this mode.
 Copy selected events, then apply operations: Choose this mode to retain the
selected events in their original form, copy them, and apply the operations.
 Preset menu: Choose one of the transform presets or one of your own transform sets.
 “Hide unused parameters” checkbox: Hides all unused menus in the Selection
Conditions and Operations areas. This provides a better overview of the settings in
use. It also prevents you from making accidental alterations.
Setting the Selection Conditions
You can define conditions that determine which events are selected for transform
operations. This done in the Selection Conditions area of the Transform window.
Each column represents a different MIDI event parameter.
 Position: Determines the time position of the event, referenced to the start point of
the MIDI region (not the start point of the project).
 Status: Determines the event type.
 Channel: Recorded MIDI channel of the event.
 Data Byte 1/Pitch: First data byte (controller number) or note pitch.
 Data Byte 2/Velocity: Second data byte (controller value) or note velocity.
Note: The parameters displayed in the Data Byte fields are dependent on the chosen
Status menu setting. Certain Status menu settings will not show the Data Byte fields at
all!
 Length: Length of the note or event.
 Subposition: Time position of the event, within a bar.
