636 Chapter 21 Song Settings and Preferences
MIDI Remote
Global Switch for controlling Logic via MIDI Commands. Clicking on the Configure
button will launch the Key Commands window (see “To assign a function to a MIDI
message:” on page 51).
Scrubbing with Audio in Arrange
This setting is required for simultaneous scrubbing of MIDI and Audio.
General: MIDI Thru
SysEx with MIDI Thru function
Incoming SysEx messages are passed through the computer to the MIDI output(s),
along with other MIDI data. This is particularly important when using hardware
programmers, as only then will you be able to immediately monitor the changes to the
synth you are editing. If you just want to record SysEx dumps, don’t select the
checkbox. It rarely makes sense to divert dumps through the computer unless you
want to record a dump, and simultaneously transmit it to a second device of the same
type.
Instrument without MIDI Thru Function
The instrument selected here will not pass events through the computer, when the
instrument is assigned to the selected Arrange track. Normally, you would set the “No
Output” instrument here.
If your master keyboard does not have a “Local Off” setting, you can use this feature to
avoid unwanted note doubling when recording:
• With multitimbral sound sources, assign the instrument (usually channel 1) which
plays the part that is heard when playing with the computer turned off.
• With mono-timbral sound sources, assign the instrument which represents the sound
generating part of your master keyboard.
In either case, you should turn down the volume control of your master keyboard
whenever you are recording tracks for any other instrument.
It is possible to disable MIDI Thru for any MIDI track in the Arrange window selectively,
by simply disabling the “R” button to the left of the track name.
