doubleA player

doubleAplayer is a software program that handles the playback of samples in a soundtrack in a musical and flexible way. The program makes it possible to adjust the tempo of the soundtrack by following the conductor and compensating for tempo fluctuations. One musician is needed to control the program and synchronize the soundtrack with the ensemble or orchestra. This ‘laptop player’ should be placed amongst the musicians on stage with an unimpeded view of the conductor.

A download link for the software can be obtained through the composer (e-mail available at publisher). doubleAplayer is a stand-alone program for Apple computers only; there is no PC version available at this time. doubleAplayer is exclusively written for performances of Michel van der Aa’s music and is not to be used for other purposes.

An amplification (PA) system is needed to perform this piece. Place two loudspeakers on stands behind the ensemble. Add two subwoofers. Position a mixing desk in the middle of the hall. Connect an audio interface to the laptop to output the sound to the mixing desk. When possible use a second laptop to run a back-up version of the doubleAplayer software.

  • Apple Macbook Pro laptop computer with 2GHz or faster Intel Core i5 or i7 processor.
