With channel aftertouch (status C-Press), or program change events (status Program)
the setting of the -1- parameter is always ignored, and the first data byte is displayed as
a beam height. With pitch bend data (status PitchBd), the setting is also ignored,
because both data bytes are used to display the beam height.
Making Different 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 made in the Event Definition Parameter box affect all selected event
definitions.
Hi Hat Mode
In hi hat mode, event definitions can be grouped together. Only one event from each
group can be played at any time position. A typical use is for preventing different hi hat
notes (open, closed, pedal) from being inserted at the same position.
To define a hi hat group, click in any of the lines at the left edge of the name column.
Click here once again to switch hi hat mode off for the line. All lines in a hi hat group
must be vertically adjacent to each other.
If you add an event within a hi hat group, all existing events at this time position are
deleted.
You can create as many hi hat groups as you want in a hyper set, but they must all be
separated by at least one line in which hi hat mode is switched off.
