Hierarchical Real Time Interapplication Communications
Real time interapplication communications are a key feature in musical multi-task operating systems. Independent applications can therefore be connected and collaborate by exchanging messages and data through communication channels. All these collaborating applications define a virtual network the user can dynamically configurate. The topology of such virtual network specifies the way applications can be connected together.

Real time interapplication communications are a key feature in musical multi-task operating systems. Independent applications can therefore be connected and collaborate by exchanging messages and data through communication channels. All these collaborating applications define a virtual network the user can dynamically configurate. The topology of such virtual network specifies the way applications can be connected together. This paper introduces a new hierarchical topology we recently implemented in our MidiShare multi-task operating system. This approach offers several advantages and particularly when a large number of applications are involved or in a multi-user context.

An Efficient Scheduling Algorithm for Real-Time Musical Systems
Scheduling problems hold an important place in most real-time musical systems. We here present an algorithm allowing to solve these problems efficiently and ensuring a bounded low scheduling cost per event in any circumstances. Its principle is to maintain events all the better sorted out as their running time gets closer.

MidiShare : a Real Time multi-tasks software module for Midi applications
This paper introduces MidiShare, a real time software module meant for the development of Midi applications in a multi-tasks context. MidiShare brings facility in most of the fields concerned with the development of musical applications: communications management, precise time control, tasks scheduling. The originality of MidiShare lies in its capacity to deal with multiple Midi applications running at the same time. Besides, MidiShare offers some interesting p... Lire la suite
This paper introduces MidiShare, a real time software module meant for the development of Midi applications in a multi-tasks context. MidiShare brings facility in most of the fields concerned with the development of musical applications: communications management, precise time control, tasks scheduling. The originality of MidiShare lies in its capacity to deal with multiple Midi applications running at the same time. Besides, MidiShare offers some interesting possibilities, particularly the one consisting in a dynamic connection between Midi applications through internal links. MidiShare was at first designed for the Macintosh under MultiFinder, it is now available on other machines.
