There are thee ways to change the pitch of notes :

Alteration

An alteration is linked to a Cell. It changes the pitch of degrees which are in the chords of the Cell ( chords of the Cell itself, chord in Sequence, Mapping, .. ).

To make a degree altered :

When a degree is optional, you can set an alternate pitch, using character | between the two pitches.
Example : inside a C chord ( C3-E-G), adding a note as optional with pitch Bb3|C4. The 7th of C, Bb, is played when 7th alteration is asked ( example : C7 => C3-E-G-Bb ) . When alteration does not require the 7th, the C4 is played ( example : Csus4 => C3-E-A-C4 ).

List of alterations :

Warning : if pitch of the chord does not exist in the Translator, use correct alteration.
e.g. with F tone, if you want B chord, and only Bb ( IV ) and C ( V ) are defined in the Translator, you should specify Bb.# ( IV.# ) or C.b ( V.b )

Examples :

Modulation

The Modulation changes the tonality of the diatonic scale used in the chords, setting right notes for an improvisation.
The Modulation can be set in the Event of a Score, or inside the compilateur (e.g. writing the tone before the chord, with a * between ).

Example of modulation in the compilateur :
grid I_got_rythm Bb 4/4
A Bb|Cm7//F7|Bb|Cm7//F7|Bb//Bb7|Eb//Ebm
A1 Bb//F7|Bb//F7
A2 Bb//F7|Bb
B G*D7||G7||C7||Bb*Cm7|F7
C Bb//F7|G*G7|C7//Bb*F7|Bb
loop A,A1,A,A2,B,A,C
