With a Sequence, you can play and naviguate within a predefined list of chords.

The Selector wich triggers the Sequence can have different actions : next, previous, reset, ...
If two Sequences have same Selector, the current alterations are compared with preferred alteration of the Sequence. Example : two Sequences can have same Selector, but the Sequence "specialized" for 7 will have priority if current alteration is like 7+, ...

Several Sequences can share the same index. With a common index, you can change to another Sequence (new Cell, ...), without changing the index.
To share an index, use a common counter in the Sequences.

Note : a program can be used as "caps-lock" to select between similar Sequences, trigerred by a same key.

If the parameters of a Sequence must be re-used (except the notes), it is possible to copy-paste the parameters, or to generalize the parameters to Sequences with the same name.
To have automatic rules for the creation of Translator, it is possible to write a list of instructions in text format ( cf. Compile section ).
