General information
The electronics for this piece can be run with a Max patch that includes infinite reverberation, general reverberation, and plays the pre-recorded sound files.
An additional musician is required to trigger the cues in the score. They should do this from a position within the ensemble using a MIDI keyboard (or directly on the computer at the mixing desk).
In both rehearsal and performance the sound engineer/musician should read the score and adjust the relative levels of the instruments and electronics on the mixing desk, according to the given context (musical interpretation, equipment, acoustics of the performance space).

Performance notes
The amount of amplification required naturally depends on the performance space, but it should never cover the acoustic sound of the instruments.
The ideal sound is a clear and rich 'close’ sound. The microphones should be placed as close to the instruments as possible.
The general level should be rather loud, but not painfully so.
