Interactive Scores (IS) are a formalism for the de- sign and performance of interactive multimedia sce- narios. IS provide temporal relations (TR), but they cannot represent conditional branching and TRs si- multaneously. We propose an extension to Allom- bert et al.'s IS model by including a condition on the TRs. We found out that in order to have a co- herent model in all possible scenarios, durations must be flexible; however, sometimes it is possi- ble to have fixed durations. To show the relevance of our model, we modeled an existing multime- dia installation called Mariona. In Mariona there is choice, random durations and loops. Whether we can represent all the TRs available in Allom- bert et al.'s model into ours, or we have to choose between a timed conditional branching model and a pure temporal model before writing a scenario, still remains as an open question.
