Notes and suggestions
Keyboard Scale The scales included in the S Series Rom are temperaments of historic
origin and non-European scales. The following is a list of the scales available.
(0) Equal: Used since the times of Bach to our times.
(1) Pure Major C: Scale based on the formula F=f+n, where F is the frequency to
calculate, f the previous frequency and n a constant. The calculation starts from the note C.
(2) Pure Major A: Identical to the previous scale, except that the calculation starts from
the note A.
(3) Mean Tone C: “Mesotonic” temperament used in the XVIth and XVIIth centuries,
calculated from the note C. Favours the perfect major third interval. The chromatic scale
is very irregular and the major 3rd intervals B-D#, F#-A#, C#-E#, Ab-C are diminished
fourths. The diminished sixth interval G#-Eb is known as the “fifth of the wolf”. The
scales used in the period when this temperament was used are C major/A minor, D
major/B minor, G major/E minor, A major/F# minor, Bb major/G minor.
(4) Pythagoric C: Temperament calculated by the mathematician, physicist and philoso-
pher Pythagoras, in use until the 15th century. It is based on a purely arithmetical
calculation of the eighth and the fifth. The scale is calculated starting from C.
(5) Werckmeister: Temperament proposed by the organist Andreas Werckmeister. It is
suitable for performing the German musical repertoire between the end of the XVIIth
century and the XVIIIth century. The keys with greater alterations appear variously
distinctive.
(6) Kirnberger: Temperament proposed by J.P. Kirnberger, pupil of J.S. Bach. This is
equally suitable for Bach’s works and the German Baroque repertoire. The keys with
greater alterations appear variously distinctive.
(7) Vallotti&Young: This Italian Temperament of Giuseppe Tartini and Francescantonio
Vallotti and later revived in England by Thomas Young is used effectively for the Italian
XVIIIth century repertoire as well as for the English repertoire of the same period. The
keys with greater alterations appear variously distinctive.
(8) Invers: This is an inverted equal temperament. The scale starts from the right instead
of the left.
(9) Chord: The notes of a scale belong to different octaves. This temperament can be
useful with Strings or Pads Sounds, to fill the overall sound by covering a wider extension.
(10) 1/4 Tone: One of the two Arabian scales, where, with respect to the Equal tempera-
ment, the notes E and B are flattened by 1/4 of a tone.
(11) Arabian: The second Arabian scale where the notes E and A are flattened by 1/4 of
a tone.
(12..15) User 1...4: Programmable scales.
Midi channel lock A general assignment of the Midi channels to the tracks which can be
saved in the General Setup. This locks the MIDI assignments for the instrument as a whole,
overriding the individual channel settings of each Performance. In this way you can have at
your disposal different Midi configurations for different situations (studio setup, concerto
setup). It also protects your entire MIDI setup from being destroyed by loading Songs which
have complex Midi setups.
