SCRIPT FORMAT

Melodomatic is controlled by a script file that defines voices that play notes, and scales that define what notes can/should be played.

A very simple script looks something like this:

:scale FMaj
.root 65
.intervals 0 2 4 5 7 9 11

:voice Lead
.pitch 1 2 3 5 6 8
.duration 1 1 2
.velocity 64 72 80

See the example scripts in the doc directory for full explanations of script syntax.
