64         * check if some engine channel parameter has changed since the last
65         * StatusChanged() call.

67         * This method can also be used to mark the engine channel as changed
68         * from outside, e.g. by a MIDI input device. The optional argument
69         * \a nNewStatus can be used for this.

72         *       replaced in future.
