-> -> Improvements to language bindings

Ayyi is language and gui agnostic. This is one of the main reasons for running multiple processes. There is a small performance penalty to pay for this, but the advantages are:

This approach is very common and is used by all major software vendors including Microsoft and Apple. It has many names and variations, and is sometimes referred to as Service Oriented Architecture or a Distributed Object system. However, the approach taken here is a practical one, forsaking some archictectural elegance for performance.

One way of thinking of the system is as a plugin system for the Song Model. It doesnt replace dsp plugins, which for performance reasons need to be in-process, but modifications to the Model are not only not processor intensive, but are too diverse in nature, to apply a restrictive api to.

The diagram below shows a possible example of a working setup. Items in grey are participants that use existing non-Ayyi communication methods.

Multiple views can be connected to the Model. These would be a mixture of ‘sequencer’ interfaces, specialised editors (eg tracker style, beat detector, looper, etc), visualisation panels, and so on.

Multiple users can simultaneously connect to the Song Model, allowing collaborative working.

It is envisaged that there would normally be only one audio and midi renderer, and in fact they are sometimes implemented by the same application.
