• The I-1 and I-2 tunings (Internal Microtuning) cannot be edited or modified
using the VL1. Microtuning data from the Yamaha SY99 or SY77 synthesizer
can, however, can be loaded into the VL1 via a MIDI bulk dump or parameter
change operation.

Equal Temperament: the standard modern keyboard tuning with
perfectly even intervals between all 12 notes of the scale. This tuning
allows transposition to any key without modification.
Internal Microtuning: These tuning are included in the system data on
the VL-1 voice disk.
Pure Major C ... Pure Major B: A brass-instrument tuning based on
their natural harmonic series. Produces a beautiful beat-free sound in
ensemble, but the tuning must be changed to match the key of the
music.
Pure Minor C ... Pure Minor B: Same as the Pure Major scales
above, but for minor keys.
Mean Tone C ... Mean Tone B: This tuning was originally devised to
eliminate the conflict caused by the third degree of the Pythagorean
tuning (below). The tuning must be matched to the key of the music.
Pythagorean: A classic tuning from ancient Greece — with a few
rough spots that were fixed in later improvements. The tuning must be
matched to the key of the music.
Werckmeister: This and the following two tunings were created to
allow transposition to any key without the need for re-tuning. They have
the curious chacteristic, however, that the "tension" of the sound
increases in proportion to the number of sharps or flats in the key
being played. Many of the classics were created using these tunings.
Kirnberger: See "Werckmeister".
Vallotti & Young: See "Werckmeister".
1/4 Shifted Equal: This is an equal temperament tuning with the
overall pitch raised 1/4 tone. It can be used with other instruments in
standard equal temperament tuning for some unusual and very "tense"
effects.
1/4 Tone: All semitones on the keyboard become 1/4-tone intervals.
1/8 Tone: All semitones on the keyboard become 1/8-tone intervals.
