Chapter 17 Editing MIDI in the Hyper Editor 433
MIDI Channel
Next to Channel, you’ll see a checkbox, and to the right of this you can set a MIDI
channel number, by dragging vertically. If you click this box (turn it on), the display is
restricted to events on the set channel. If the box is unchecked, the channel parameter
is ignored, and matching events on all channels are displayed.
Adjusting Multiple Event Definitions Simultaneously
Just as you can adjust the parameters for several MIDI regions at once, you can set the
parameters of several event definitions simultaneously. Select several event definitions
in the name column, by holding down Shift and clicking on them. You can also use
Hyper > Select All Event Definitions to select all event definitions, and then deselect
some of them by Shift-clicking on them.
Any alterations you make in the Event Definition Parameter box will affect all selected
event definitions.
Converting Event Definitions
You can redefine an event definition (along with all events). The values of the events
are retained, but the event type is changed to the new event definition.
To convert an event definition and all events:
1 Select the event definition you want to convert.
2 Do one of the following:
 Choose Hyper > Convert Event Definition (or use the corresponding key command).
 Double-click on the name column of the event definition that you want to convert.
3 Choose the desired settings in the Convert Definition dialog, and press the Convert
button.
On the left (Convert), you can see the parameters of the selected event definition, and
on the right you can define the parameters of the destination event type. The current
settings (of the source) are used as default values for the destination.
