ANTESCOFO Case Study

2.1.1.1. ANTESCOFO

ANTESCOFO is a score-following system that enables to code interactions between the instrumental parts and the computer-generated parts by providing a proprietary programming language [Giavitto, Cont and Echeveste, 2015]. ANTESCOFO is an event based customizable score-following. Accordingly, its most important programming entities are events and actions [Giavitto, Cont, and Echeveste, 2015]. Figure 2.10 shows a sample code in ANTESCOFO language with events and actions; Events are symbolic elements in the score to be identified by the score-following core, and actions are triggered commands associated with events (example taken from the Antescofo v 0.8l official download) [Giavitto, Cont and Echeveste, 2015].

Figure 2.10. ANTESCOFO Sample Code.

In Figure 2.10, the NOTE label identifies the event of a note with pitch C4 and symbolic duration one-beat. The inside labels are actions triggered when an event is detected by the score-following core engine. This short example shows clearly the similarity between ANTESCOFO and Music-N Language where sequential-symbolic time events are mapped to commands. In summary, ANTESCOFO programming-language design is event-driven and reactive.

One consequence of this event-driven (atomic) approach is that horizontal logic flow in the score became a secondary role in the logic representation,
Therefore, it’s the author itself and not the tool who should define the creative path, so tools should be designed
