Inv.Ch-1, Inv.Ch-2
These modes have been created for the purpose of recording and notating electric
bass parts with Guitar-To-MIDI-Converters. “
−
2” is designed for four-string bass, “
−
1” for
five-string bass (with an additional high B string). The principle is the same as Inv.Chan,
but the number of the MIDI channel is reduced by 1 or 2, in order to convert the
channels properly for bass string assignment.
The string assignment for a four-string bass will be 3 to 6, for a five-string bass 2 to 6
(counted from highest to lowest string in both cases), just as with guitar strings that
sound one octave higher. Notes on channel 1 will be assigned to the highest string.
In all of these assign modes, notes below the lowest string will not be displayed at all.
Also, notes generally can only be assigned to strings on which they are actually
playable. (An F2 can only be played on the lowest string of a guitar, so the channel
assignment is completely ignored in this case.)
You can create a two-stave Score Style that displays the MIDI Region twice: once using
regular music notation, and once as tablature. The indicated split point can be ignored
in this case. There is a default style for this (named Guitar Mix), in the Logic default
song.
Some more information concerning tablature notation in Logic:
• You cannot insert clef changes in staves using tablature. If you want to change
between tablature and regular notation in the same staff, you need to cut the MIDI
Region at that particular point, and assign the desired Score Styles (see “Basics” on
page 529) to those Regions.
• Guitar tablature relates to regular treble clef. If you use the octave-transposing treble
clef (Treble-8) for guitar notation (as it is done in most guitar music, and also in the
above example), you need to set the tablature’s Transpose parameter in the Score
Style window to
+
12.
MIDI Meaning
The settings in this window determine, if and to what extent, the insertion of the
symbols listed here have an effect on the MIDI playback of the notes to which these
symbols are attached. The window is opened from the menu Layout > MIDI Meaning.
For each symbol listed here, two parameters can be determined, which change the
MIDI output of all notes to which these symbols are attached:
Velocity
This value is added to, or subtracted from the original velocity value of the
corresponding note.
