This patch was made originally made by Greg Beller (IRCAM), re-adapted for 64bit and Spat5 in 2021 by Joao Svidzinski (IRCAM).

This a a revision of this version in 2022 for a concert in Sevilla with the Zahir ensemble (November 2022) by Max Bruckert.

General Setup

Audio setup

Two inputs :

• adc 1 : Voice
• adc 2 : Double bass

16 outputs :

• dac 1 to 8 : Live electronics for surround setup
• dac 9 to 16 : Soundfiles for surround setup

DSP Status Options

Beware this patch is initialised to be set at I/O vector size 128 and Signal Vector size 64
Overdrive On
Audio Interrupt Off

Midi Setup

Midi setup
Use a BCF-2000 to control the treatments levels.

Sliders:

• Control 1 [ctlin 1 1] = Baritone input treatements level in dB
• Control 2 [ctlin 2 1] = Double bass input treatements level in dB
• Control 7 [ctlin 7 1] = Samples level in dB
• Control 8 [ctlin 8 1] = Treatments level in dB

Check “Midi I/O” if you need to hook up pedal for triggering.

A MiraWeb interface is there with the “MIRA” button for mixing outputs and triggering events

Software installation

• Download Patch_IntroTenebres_Cendo_2022.dmg.

Performance notes

Beware that this patch needs two persons to trigger events. It’s asynchronous ! Pedal numbers are not the same for each one.

1- Conductor on stage or another person in the soundbooth == for soundfiles
2- a person in the soundbooth = Live electronics.

There still is a synchronous attempt in the main patch but seems to be a little buggy. We chose to return to the original system developed for the creation.
Live electronics applied on the voice are cued with the “Live Event” system and go out from the Live Electronics Master
Live electronics applied on the doublebass are cued with the “Sfile Event” system and go out from the Live Electronics Master

For readable purposes I made a Mira patch that could be an “in between” solution to that  One person triggering both in the sound booth.

Check out Midi I/O if you need to hook two midi controllers for triggering

When rehearsing, please beware that Live events (the voice and Cb entrances) are sometimes opened in a previous Event, so jumping back and forth can be a little tricky. Check out the EVENTS window if you need more info. Sometimes Events auto-stop…
