Instructions

1. Audio setup

Frammenti di memoria abolita is a piece for violin, viola, cello, Daf and electronic object. The electronic part of this piece is performed by the electronic object.

1Bis. Details for the electronic object

The electronic object is a piece of wood (50cmx25cmx5cm) with a RIOT (from ISMM team) and two FSR sensors inside. The communication between the RIOT and the computer with Max is done via WLAN.
IRCAM team host the electronic object.

The electronic object triggers audio files from the computer with Max.

2. Loudspeaker setup

Two adapted loudspeakers have to be positioned on stage, behind the electronic object.

3. Ethernet setup

The actual WLAN configuration for the electronic object is
WLAN name : manifeste2021 / WLAN password ircam-manifeste
RIOT transmission IP is done to 192.168.0.40
Please set up your computer IP address according to this configuration.

4. Software installation

Max 8.1.11 was used for the concert.
The patch has been played in this config : 44.1kHz, IO 128, VS 128, Overdrive ON

  • Copy the _BEJA_FRAMMENTI folder into your desktop
  • Open Max, add the whole _BEJA_FRAMMENTI folder into Files Preferences

  • Launch the main patch _MAIN_frammenti.maxpat
  • In [p riotbitalino 0 8888] check the input of datas.

5. Events

There are 24 events, who recall the matrix and trigger sounds.
Events can be triggered by the computer music designer, with a space bar shortcut, or by the electronic object player with a midi pedal.

5. Patch presentation

[p sensor] is scaling of riot values.
[p MATRIX] is a routing from scaled riot values to understandable values for sound file player
[p DSP] is the main host place for sound file players
[p MASTER] is a level definition table for each sound file
[p MIRA] is the wireless interface for the electronic player to manage events.

6. Score for the computer music designer

You have to fade out the “re” sound on bar 97.
Please also adjust the dynamic on the following sounds according to venue and player :

  • re (sound C on score)
  • Air (sound I on score)
  • Climax (sound H on score)
  • Ring 2 (sound B2 on score)
  • Chords (sound D on score)

Be sure to start from 0 and pass each preset sequentially.
See [p MIRA] for details.

7. System calibration and tests

Sensors :
Check that no slider stays freezed when moving the slider
Check the battery : >= 3.9 charged, < 3.5 empty

Program note

L’énergie intense du matériau se transmute du daf aux cordes et jusqu’à l’électronique, les reliant tous en un cycle d’énergie unique, en une entité unique. Le daf est un instrument   percussion traditionnel perse, fréquemment associé à des expériences spirituelles et de transes. Son timbre est hautement versatile et contient différentes couches sonores : d’une part, des sons profonds et résonants, aux riches harmoniques, et, de l’autre, des tintements qui y semblent éparpillés, formant des timbres métalliques et granulaires. Le daf constitue l’impétus de cette pièce, et de lui découle le matériau développé et étendu par les cordes et l’électronique, le faisant accéder à d’autres dimensions. Cela se traduit autant par le recours à un matériau aux caractéristiques similaires, que par la production de contrastes susceptibles de mettre en avant chacune de ces caractéristiques. La nature profonde et primitive du daf donne lieu à des moments de rituel associés à des souvenirs ancestraux substantifiques de la nature humaine. C’est à partir de ces réflexions que les matériaux des cordes et de l’électronique ont été élaborés, sur la base de trois archétypes sonores : les sons d’*air*, les *tak* (des sons relativement secs et aigus) et les *dum* (un son profond, largement résonnant). Autour de ces trois archétypes sonores, des variations sont produites, qui créent la forme de la pièce.
