"¡PORTATE BIEN!" explores emotional terrains which keep revealing unexpected outcomes, both hilarious and scary. The piece uses a ventriloquist doll as its main controller. The doll (Andreita) sends data from an accelerometer placed in her head and a multi-touch sensor placed in her body which is activated when the mouth opens and closes. The voice is the main sound source. Most of the synthesis is in real time. There are also some pre-recorded files.
