General information

The original version of the electronics for this piece was for quadraphonic analogue tape.

The electronics for this piece can now be run with a Max that plays the pre-recorded sound files.

The starting cue in the score must be triggered by a musician directly on the computer at the mixing desk on the starting signal from the conductor, and left to play through uninterrupted until the end.

Seventeen events corresponding to time markings in the score have been set in the patch, in order to facilitate rehearsal from specific points in the piece.

In both rehearsal and performance the sound engineer/musician should read the score and adjust the relative levels of the orchestra and electronics on the mixing desk, according to the given context (musical interpretation, equipment, acoustics of the performance space).


IMPORTANT: in recent MacOS versions, there is a known issue when downloading

Max standalones through browsers (such as Safari, etc.)

Before to download, one needs first to go to ‘System Preferences/Security & Confidentiality/General’

and check ‘Authorize the applications downloaded from: anywhere’.

If you do not do it, the system will display a misleading message saying that the ‘file is damaged’.

You just need to change the security parameters as described above, then restart the standalone.

For MacOS Sierra and later: the ‘anywhere’ option is by default disabled.

To enable it again: start the application Terminal and type the following:

« sudo spctl --master-disable »

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 general level should be rather loud, but not painfully so.
