Chapter 33 Working With Notation 787
Note: As most Guitar-to-MIDI-Converters send notes (played on different strings) on
different MIDI channels, the Channel and Inv. Channel modes are suitable if you’re
using a MIDI guitar to record MIDI regions. The tablature notation is displayed exactly
as the music was played during recording.
Inv. Channel –1 and Inv. Channel –2
These modes should be used when recording and notating electric bass parts with
Guitar-to-MIDI-Converters.
 “–2” is designed for four-string bass.
 “–1” is designed for five-string bass (with an additional high B string).
The principle is the same as Inv. Channel mode, but the number of the MIDI channel is
reduced by 1 or 2, in order to properly convert the channels 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.
Further Information on Tablature Notation
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-staff 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 found in the Logic Pro default
project.
You cannot insert clef changes in tablature staffs. 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 staff styles 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 Staff Style window.
