General Architecture

The prototype of the computerized system of electronic lecterns/music editors will be implemented by using technologies based on: HPCN, object-oriented paradigm, real-time technique; thus, the name MOODS: Music Object-Oriented Distributed System. The implementation of MOODS prototype involves both hardware and software aspects.

MOODS Architecture

A MOODS system, as reported in the figures, will be comprised of:

Specific hardware for DLIOOs and MASE will be built by using commercial components but considering ergonomic aspect and usability -- i.e., DLIOO-HW and MASE-HW. MASAE and the Database use standard hardware.
MOODS Ergonomy

The adaptation, customization of LIOO, MSLIOO software will consists in adding parts (i.e., methods and specialized classes) for distributing lecterns and controlling them on the network (see {LIOOEVOLUTION96}). New functionalities due to the possibility of working cooperatively on the same score will be implemented.

Therefore, software support for integrating DLIOOs with MASE/MASAE along the network, configuring the network/orchestra (ONCM), and monitoring the network behavior (ONCM) will be implemented by using HPCN technology.

For these reasons, a great work will be performed by integrating components. The complete system will reach a greater value with respect to the simple sum of the corresponding components, since a new set of strongly innovative products with a set of new functionalities will be implemented.

In the following subsections, details about the main components of MOODS are reported. This technical part has been derived from the preliminary study of DSI {LIOOEVOLUTION96}.

The main result:

Musicians with MOODS
According to the following architecture in which more than one director can be present with more than 200 DLIOO continuosly configured from completely passive PDLOOs to full power DLIOOs:
