Attaining Intonation ( or adjusting to Just)

[size=2 font="times new roman"]I generally type in Barbershop Quartet music (all four parts) in midi to help me learn a new piece.  What I’d like to do is adjust  the pitches of the notes to accommodate Just Intonation.  (Barbershop music cannot be played on a piano precisely as many of the notes fall in between the keys.)  So instead of an equally tempered scale, I want to bend each note into a Just Intonation scale.  This is a non-trivial task: even after I calculate what to do (what pitch wheel values I apply to each note), doing it will be a horrendous task – going into the event list and manually adding pitch wheel commands for each note.  I’ll probably have to write a CAL program for it and I’ll get wrapped around an axel trying to figure out how to do that.

[size=2 font="times new roman"]But I’m guessing that it’s already buried in the software somewhere: in one of those plug-ins, or part of that “snap to scale” button that I have yet to figure out.

[size=2 font="times new roman"]Anybody been there and got some guidance  for me?

WR's link was correct. It should lead you to a page called Scala Downloads. 

I don't think you will be able to use those scales with the LE versions because those versions only have limited editing capabilities. 

Here's what the z3ta+ Help screen says about it:  (Press F1 in z3ta+).

Microtuning, Alternative tunings

---

Microtuning has been an interesting field of research for musicians and physicists for years. Several synthesizers have included some sort of microtuning abilities to allow performers to use alternative tunings to the standard 12-tone equal-tempered system.
One of the powerful features in Z3TA+ is that it can load native Scala^TM .scl microtuning files. 
 
Scala is a powerful freeware software tool for experimentation with musical tunings, such as just intonation scales, equal and historical temperaments, microtonal and macrotonal scales, and non-Western scales. It supports scale creation, editing, comparison, analysis, storage, tuning of electronic instruments, and MIDI file generation and tuning conversion. All this is integrated into a single application with a wide variety of mathematical routines and scale creation methods.
Scala is ideal for the exploration of tunings and becoming familiar with the concepts involved.
In addition, a very large library of scales is freely available for Scala and can be used for analysis or music creation.

To load a microtuning definition file, select Load Tuning definition file under the OPTIONS button. When a microtuning file is active, the filename is shown in this menu option.


The tuning definition file selected is remembered and reloaded in a per-preset basis, or as global by selecting Global Tuning in the Options menu. (The files must be moved to the \Tunings folder so the automatic reloading option can find it.)
Not limited to 12-tone scales, Z3TA+ microtuning allows for any number of notes, including mean-tone and quarter-tone scales.
When a tuning with a different number of tones than 12 is loaded, the Octave control adds or subtracts the selected scale number of tones to keep the oscillators in unison when changing octaves. The arpeggiator will also skip the number of tones to follow the scales correctly.


Z3TA+ includes 200 Scala tuning definition files with the default installation. A file with over 2900 tuning definition files (.scl) can be downloaded for free from:
http://www.xs4all.nl/~huygensf/doc/scales.zip


Check a brief description of the scale files in:
http://www.xs4all.nl/~huygensf/doc/scalesdir.txt


If you download it, be sure to extract the .scl files to the Tunings folder in order to allow Z3TA+ to recall them for every program.mode
