Microtuning in Logic 7 - The problems;-)

Notes on Tuning implementation in Logic 7. October 2004.

How to LucyTuned your tracks to be played by Virtual instruments in
Logic 7.

From the Main Menu go to File/Song Settings/Tuning .....
Click on the "Fixed" button.
Choose "John Harrison (1775), almost 3/10-comma, third = 1200/pi"
Select "Fixed" Root Key to A (i.e. A4 will be 440 Hz)
Click on "Copy to User" button.
This will set A at 0.0 and all the "black" notes will be set to sharps
(notice their negative values).
i.e. C#-D#-F#-G#-A#.
Click on "User" button, and set "User Root Key" to A
(This is so that your retuning will be set so that A will play at 440Hz.
[If you select any other User Root Key, the resulting tuning will be
derived from that note's frequency in equal temperament, and will no
longer be based on A=440Hz.
This may cause problems if you wish to play with other LucyTuned
instruments.
(e.g. guitars, whose strings would otherwise have to be retuned.)]
If you wish your tuning to be other than the now selected
C–C#-D#-E-F-F#-G-G#-A-A#-B (0b5s),
you will need to adjust the notes.

To make the black notes be flat.
Use these cent values.
Bb= +22.5
Eb= +27.0
Ab= +31.5
Db= +36.1
Gb= +40.6

Change as required or select the values from the rightmost column "l"
in the following table.

The way in which Logic have designed this system, creates a difficulty,
if you should wish to use more than
one assignment for a note.
To use both Ab and G# (for the chords F minor and E Major respectively)
in the same song, you will have to do some imaginative
tweaking.
There are a number of way this can be achieved.
a) Run two different songs with different tuning assignments.
b) Remove and replace the offending notes/chords in the audio mix.
c) Use another method of retuning.
i. EXS24 as explained below
11. Use seperate tracks of seperate tunings.
iiI. Pitchbend (only to nearest 1/64th of a semitone) specific notes to
compensate (Last resort).
d) Propose or invent a new method.

When recently producing LucyTuned Lullabies II, with James Sanger (of
Keane & Dido producer fame),
we used a combination of methods a), b), c)i & c)ii.
