| * graph. This only works if at least the first 5 pfields in the Csound score | ||
| * (instrument number, time, duration, MIDI key, MIDI velocity) follow the | ||
| * Silence conventions declared in Event.hpp. | ||
| * | ||
| * Score literals in the CMask parameters are simply appended to the Csound | ||
| * score header in the Score object, and likewise are copied directly and | ||
| * without any processing to the translated Csound Score. | ||
| * | ||
| * For documentation and examples for CMask, see [Andre Bartetzki's original | ||
| * documentation](https://www.bartetzki.de/de/software.html). | ||
