quince

Quince is a composition software, similar to a daw, for editing time-based data on the mac.
Features :
- the paradigm "tape-recorder - mixing desk" is broken: there are no channels.

arbitrary numbers of objects can be layered, thus displayed and edited, on top of or next to each other.
- nested object-trees: each event may contain arbitrary numbers of events which themselves may contain any number of events and so on.
- all the functionality is implemented in a plug-in structure with an open API. adding custom plug-ins requires a minimum of code.
