Inv. Chan
Like Channel, but counted from the highest string (1) to the lowest (6 and above). This
way of numbering the strings is generally used in traditional guitar literature.
As most Guitar-To-MIDI-Converters send notes on different MIDI channels, according to
the played strings, the last two modes are suitable if you use such an instrument to
record MIDI Regions. In this situation, the tablature notation is displayed exactly as the
music was played during recording.
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, and 2 to 6 (counted from
highest to lowest string in both cases) for a five-string bass, 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 are not displayed at all. A
further point to note is that notes can generally only be assigned to strings on which
they are actually playable. (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 situation. A default style for this (named Guitar Mix) is 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, and assign the desired Score Styles (see “Basics” on page 380) to the resulting
Regions.
• Guitar tablature relates to a regular treble clef. If you use the octave-transposing
treble clef (Treble-8) for guitar notation (as done in most guitar music, and in the
example), you need to set the tablature’s Transpose parameter to +12 in the Score
Style window.
