386         * These options allow to override the precise default behavior of the
387         * envelope generators' state machines.
388         *
389         * @b Note: These EG options are an extension to the original gig file
390         * format, so these options are not available with the original
391         * Gigasampler/GigaStudio software! Currently only LinuxSampler and gigedit
392         * support these EG options!
393         *
394         * Adding these options to the original gig file format was necessary,
395         * because the precise state machine behavior of envelope generators of the
396         * gig format (and thus the default EG behavior if not explicitly overridden
397         * here) deviates from common, expected behavior of envelope generators in
398         * general, if i.e. compared with EGs of hardware synthesizers. For example
399         * with the gig format, the attack and decay stages will be aborted as soon
400         * as a note-off is received. Most other EG implementations in the industry
401         * however always run the attack and decay stages to their full duration,
402         * even if an early note-off arrives. The latter behavior is intentionally
403         * implemented in most other products, because it is required to resemble
404         * percussive sounds in a realistic manner.
