Un tiro de dados

I. Medianoche mp3 file (3.5 Mb)(3:52) - it is midnight in a cemetery. Bells start to toll if the player stops. The amount of time that the player can stop before the bells start to ring gradually decreases, until by the end it is impossible to keep them from ringing.

II. Aleatoria mp3 file (7.8 Mb)(8:29) - the computer plays some number of random notes of the duration of the last note released by the player. Presets store the number of notes, the interval above and below which the computer picks its notes, and the range of timbres with which the notes are played.

III. Relexión mp3 file (8.4 Mb)(9:04) - each pitch class has a checkbox--if it is checked notes of that class are echoed through a series of MIDI timbres. Presets store which pitch classes are echoed (checked), how many delays there are, what the delay time is, and which timbres are used. There is a preset rhythm track that can be started by pressing a pedal or clicking on a button on the screen.
