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 with this software synthesizer, 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.
