Appendix E: Using TUN Files
By Jacky Ligon
About Microtuning
Microtuning, or "microtonality" are methods for tuning musical instruments
whereby musicians may explore and compose with ethnic, historical and
contemporary tuning-systems. Microtuning musical instruments allows one to
use scales which may have pitches lying between the notes of our familiar
Western 12 tone scale. These pitches which are found in the 'cracks' of 12 Tone
Equal Temperament are one of the things that give music's of Bali, India, Africa,
Thailand, Turkey and the Middle East (to name but a few) a special intonational
flavor, but is something that is of immeasurable value to the contemporary
acoustic and electronic composer, who may require a more broad palette of
musical pitches for their music.
The quest for creating beautiful and musically useful tuning-systems has been an
unending process of discovery and debate amongst musical theorists,
mathematicians, physicists and musicians going back to early history. Quite
often the reasons for microtuning instruments may involve improving the
consonant intervals of a tuning-system for sweeter sounding harmonies, as well
as offering wider variety of choices for melody. "Microtuning" an instrument can
sometimes mean there may be less or more than 12 tones in an octave, or even
that the octave itself may be stretched or compressed. Microtuning is a vast
topic, rich with lore, music and an infinity of musical possibilities for the sonic
explorer.
Creating TUN microtuning files with SCALA
Scala is a freeware utility developed by Manuel Op de Coul in the Netherlands,
which can be used for the creation and analysis of historical, ethnic and
contemporary microtunings. A powerful capability of Scala is that it enables the
user to create the proprietary tuning data required for microtuning a wide range
of hardware and software synthesizers and samplers.
Scala may be used to create the TUN format microtuning-files needed to explore
microtunings with this instrument.

Specifying the Reference Frequency of a Microtuning
One of the powerful capabilities of the TUN file format and Scala, is the ability to
specify the pitch and midi note which will be the reference pitch for the
microtuning in use. This becomes a very important consideration when one is
using a number of different synthesizers and wishes to keep them in tune with a
given base frequency. It is very common for one to specify a chosen concert

pitch such as A440 Hz or C261.6256 Hz as a reference for a microtuning,
however, the flexibility of the TUN format and Scala enables one to specify this
frequency arbitrarily. In Scala this reference is called Map Frequency.
As well as being able to specify the Map Frequency, one can also specify a
central midi-note, which will become the starting point for the microtuning in use.
Being able to specify a particular midi-note on the controller, provides a way to
map a microtuning beginning on any desired midi key, making it easier to
navigate the keyboard when there may be more or less than 12 tones per octave,
or where one may desire to have the notes of a tuning fall on certain physical
keys.
Important Note
When one uses a TUN microtuning-file in the , the above specified mapping
properties will override the Master Tuning reference. Normally when one is using
the default 12 Tone Equal Tempered Scale, the Master Tuning will be used to
make fine pitch adjustments around the standard concert pitch of A440 Hz, but
when one has specified another pitch base for a microtuning when the TUN file is
created in Scala, such as C261.6256 Hz, the data in the TUN microtuning-file will
provide a new pitch reference.
