General notes 

A unique stereo sound file accompanies the bassoon, which undergoes some transformations (filtering, distortion, chorus, frequency shifting).

The bassoonist plays following a click.  

A first sound file (introvox.aif), lasting 36 seconds, plays alone at the beginning of the piece. Then the player triggers a second sound file (despair.aif), lasting 9'17", which is synchronized with a click track.

A soundfile with the audiofile "despair" with click superimposed, for practicing purposes, is available in the folder "Practicing CD", for the instrumentalist 
Score and recording by bassoonist Martin Brice are also available, respectively in "Score" and "Recording" folders.

Stage Setup

This piece can be played in simple stereo configuration, with 2 loudspeakers, or in double cross stereo configuration, with 4 loudspeakers. 

A DPA 4061 microphone is attached to the top of the instrument with an elastic, + two Neumann KM 184 microphones are used, in order to catch both registers of the instrument, corresponding to the position of the hands of the player.

These three microphones are then mixed in mono and then send into both adc 1 + 2 in the patch (same signal for the two channels).

A secondary computer can be set to show cues to the instrumentalist (optional).

Audio and Midi Setup

The sound files from the electronics are output from the audiocard through dac 1 + 2. The electronics can be also output in "cross Stereo" configuration (cross stereo: left channel is output from front left and rear right, while the right channel is output from front right and rear left).

Treatments for the basson are output through dac 3

The click track is output through dac 4

The sound engineer mixes at the console the relationship between the sound files and the treatments.

- Main computer configuration (the one that plays the sounds and treats the bassoon): click on « bang here to get the + interface IP information for this computer ».

- Launch the _OSC-receive-transmission.maxpat patch on the secondary computer onstage and click on bang here to get the + interface IP information for this computer ".

- Copy the IP of the host computer in the "remote IP here enter" field of the secondary computer (in the textedit object, enter the IP numbers, than click anywhere outside, to send them).

- Copy the IP of the secondary computer in the "remote IP here enter" field of the main computer.

For the beginning of the piece : 

- The pedal is used only to trigger the beginning of the piece and then the second sound file. At the Event 1, a message "light" triggers an automatic fade for lights. (These first two MIDI events can be easily executed by hand, in case you want to get rid of the pedal for the bassoonist).
