  Software to design multimedia scenarios is usually based either on a fixed
timeline or on cue lists, but both models are unrelated temporally. On the
contrary, the formalism of interactive scores can describe multimedia scenarios
with flexible and fixed temporal relations among the objects of the scenario,
but cannot express neither temporal relations for micro controls nor signal
processing. We extend interactive scores with such relations and with sound
processing. We show some applications and we describe how they can be
implemented in Pure Data. Our implementation has low average relative jitter
even under high cpu load.
