92 schoenebeck 3082 /** @brief Real-time instrument script (sfz format extension).
93     *
94     * Real-time instrument scripts are user supplied small programs which can
95     * be used by instrument designers to create custom behaviors and features
96     * not available in the stock sampler engine. Features which might be very
97     * exotic or specific for the respective instrument.
98     *
99     * This is an extension of the sfz format, thus a feature which is currently
100     * only supported by LinuxSampler. Scripts will not load with other sfz
101     * players right now. The dedicated sfz opcode for this purpose is:
102     * @code
103     * script=path/to/scriptfile
104     * @endcode
105     * This opcode is recommended to appear in the sfz file's global section,
106     * however ATM the precise location of the opcode is simply ignored.
107     * Currently there may only be one @c script opcode per instrument. Further
108     * @c script opcodes will currently simply be ignored. In future using
109     * multiple @c script opcodes will be supported as well, the scripts will
110     * then be executed by the sampler in the order in which their opcodes
111     * appeared in their sfz file.
112     *
113     * You find more informations about Instrument Scripts on the LinuxSampler
114     * documentation site:
