Unlike the Region playback parameters’ Delay option, this only affects individual event
types or note numbers, which is very useful for drum programming (flams, for
example).
In general, it is useful to transmit controller data slightly before or after the exact grid
positions, to improve the timing of the notes lying on the grid positions.
Length of Notes to be Added
You can use the Length parameter to set the length of notes to be added, measured in
divisions (the left number), and ticks (the right number).
To guarantee optimum timing when drum programming, you should ensure that note
off events are never transmitted at the same time as note on events. Use note lengths
that aren’t close to straight note values, such as 100 ticks (1/48 note = 80 ticks, 1/32
note = 120 ticks). Very small tick values are also unsuitable, because note off events may
sometimes be transmitted at the same time as note on events, at the same position.
Event Status
If you grab the right side of the Status line, a pull-down menu opens, enabling you to
set the status for this event definition line.
MIDI Channel
Next to Cha, you’ll see a checkbox, and to the right of this you can set a MIDI channel
number. If you check this box, 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.
First Data Byte
The bottom line shows the -1- parameter, where you can determine the first data byte
of the displayed event.
As an example, if Note is set as the event status, you can determine the pitch (note #)
that should be displayed in this event definition line. If the edited MIDI Region is played
by a mapped instrument, a pull-down menu that features the names of the input notes
(drum sound names) appears here.
As with the MIDI channel, the checkbox determines whether (if checked) only events
with the defined first data byte should be displayed, or whether (if unchecked) the
setting should be ignored. In the case of note events, the velocity values of all notes
(regardless of pitch) would be displayed in the relevant event definition line.
If Control is set as the event status, you can use a pull-down menu to determine the
controller type (controller #).
