452 Chapter 13 Event List
Release Velocity
Logic is able to edit the release velocity of a note Event in the Event editor.
To view release velocity data, enable the 001011 view filter button to the left of the
event list.
Num and Val
Num determines the function of the Meta Events you create, and Val determines the
value that is sent. You should only ever insert and edit the following Num values in the
Event List window:
Num = 47
Send Byte to MIDI. This sends the track instrument any byte value (Val) between 0 and
255 ($00-$FF). As a usage example of this Meta Event; if you send 246 as the byte, this
is equivalent to a MIDI tuning request message. The display will show “Send Byte $F6”.
Only use this Meta Event if you know what you’re doing—if you don’t, your sound
modules and synths may start to behave very oddly indeed.
Num = 48
Switch Fader. This will send MIDI events to a particular output number (Val) on a cable
switcher. You first need to connect a cable between a track instrument and the cable
switcher in question.
Num = 49
Goto Screenset. This event selects a Screenset (Val determines the number). The track
instrument is irrelevant.
Num = 50
Song Select. This event will switch songs on a MIDI data filer/player (Val = the stored
song number). The track used for this event is irrelevant.
Num = 51
Goto Marker. When this event is sent, playback will jump to another marker (Val
determines the marker number). Once again, it doesn’t matter which track this event
appears on.
Num = 52
Stops playback.
Meta Events can also be generated by Fader Objects in the Environment window.
