Determine the string assignment
Because most notes can be played at different positions (frets) on different strings, the
Assign parameter in the Tablature pane performs an essential role. In most cases, the
MIDI channels of the individual notes determine the string assignment. The MIDI channel
parameter of an individual note has no impact on MIDI playback. The playback channel is
determined in the Track inspector, found in the Main window.
Click in the Assign column (for the corresponding Tuning Set), and choose from the
following string assignment options:
• Pitch
Logic Pro assigns each note to the string on which it is playable, at the lowest
possible position. In order to influence the string assignment, there is a rule (in Pitch
mode only) that a note’s fret position cannot be lower than its MIDI channel.
This method is generally used when notes are recorded from a MIDI keyboard:
• An A3 (on MIDI channel 1) is displayed on the second fret of the G string. If you
want the note to be displayed at a higher position (to correctly display the proper
fingering of a passage), you need to set its channel to 3 or higher. This means
that the fret position cannot be lower than 3, so the note is displayed at the D
string’s seventh fret.
• If the channel is between 8 and 12, the A3 is assigned to the A string on the 12th
fret, and to the low E string (17th fret) for channels 13 to 16.
If you want to force even higher positions, you need to use one of the other
assignment modes.
• Channel
In this mode, the number of the string (1 to 6, counted from the lowest string)
corresponds to the MIDI channel. Channels 7 to 16 are assigned to the highest
string.
• Inv. Channel
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 tablature.
Note: Because 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. Ch–1 and Inv. Ch–2
These modes should be used when recording and notating electric bass parts with
Guitar-to-MIDI Converters.
• “−1” is designed for five-string bass (with an additional high Bstring).
• “−2” is designed for four-string bass.
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 is 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 are assigned to the
highest string.
