Description of the piece

"Etymo" (1994) is a piece for ensemble and live electronics. It is divided in three movements. Only voice is treated by electronics in real-time.

Elements needed to play the piece

• 1 computer (1 laptop with MacOS > 10.12.6 core i7 + Max 8.1.1) for electronic treatments and eventually one laptop with max for displaying the events to the keyboard player),
• 1 proximity microphone for the singer + microphones for instruments amplification (4 DPA 4061, 2 DPA 4088, 5 DPA 4021, 4 Neumann KM 184, 2 Neumann KM 140, 2 Neumann KM 150, 2 Schoeps MK4, 2 Sennheiser MKH 40, 2 Senheiser MD421, 2 Shure KSM 137, 4 * AKG C535)
• 1 mixing console (the electronic requires at least 8 outputs and 1 inputs)
• 8 points diffusion system
• eventually one more loudspeaker placed at the top of the concert hall (for the last event of the piece)
• 1 in / 8 outs audio interface
• 1 keyboard with at least 88 pitches (to trigger the events and play the samples)
• 1 usb midi mixer (for instance bcf2000).
• 1 reverb for electronics

Patch informations

Installation on the main computer (electronic treatments)

Copy the folder 'Etymo' on your hard disk.

Launch max, and select the folder 'Etymo' in the 'file preferences' menu of max.

Open the file 'Etymo_2020' in max.

Description

The concert patch is composed of:

• Top left : configuration and initialization interface
• Top right: events trigerring interface
• Bottom: live mixing faders and viewmeters

Initialisation

To initialize the patch:

1. load soundfiles + samples for samplor (top left of the patch)
2. choose midi devices

eventually configure udp (set the IP of the laptop used for display)

3 - Bang on init

Audio parameters will reset as follows:

dsp sigvs 64, iovs 256, sr 48000, takeover 1, max preempt 1;

4 - Dsp on

You are ready to play the piece.

Folder 'Etymo-Laptop'

You can use a laptop for keyboard player so that he sees the event trigerring that he controls during rehearsal.

For that connect the laptop with an ethernet cable to the main computer and give the ip adress of the laptop to the main computer (click on 'eventually configure udp' at the top of the patch in the initialisation section).

Triggering of events

Only one keyboard is used (see figure 1). It triggers both the samples and the events. High pitches (from 39 (C sharp 2) to 94 (F sharp 7)) trigger the samples. The low pitches (from 21 (A0) to 34 (A sharp 1) of the keyboard trigger the events: each cue correspond to one pitch in a chromatic order: cue 21 (A0), (A sharp 0) etc... If the keyboard makes a mistakes, there are two possibilities: if the pitch is above the last one and below the highest pitch of the section, the computer jumps to this pitch. Otherwise, nothing happens. The changing of section is made with the last event of each section, so if the keyboard forget it, you should trigger it by hand.

Rehearsals

For rehearsal (when mode "enable control sections" =1 in the main patch), sections can be selected with keyboard: keep pressed pitch 107 and then select pitch 60 to 91 for section 36 to 79 (see figure 2 below). Pitch 108 (C8) initializes the patch.

You can use a second laptop for displaying events to the keyboard player. The communication with main computer is made with udp/osc.

Simulation

There is a simulation file (midi + voice recording) that you can use directly from the patch (’simul front’) or from Live (file ‘Etymo-simul-2006’) with some markers on some starting bars. If you use the simulation from max, read the midifile and open the soundfile, then start simul (toggle start/stop). You can only start from the beginning of the piece and cannot stop during simulation so it is preferably to use Ableton Live or another sequencer for more flexibility.

The simulation files are in the folder ’simul’.

SOME MIXING INDICATIONS

• first sfile: as if it was very far
• start the filter quite low
• bar 39 2 raise progressively
• then keyboard plays samplor
• then sfile
• bar 41 1 samplor louder
• bar 51 4 flanger louder
• treatment 'haro voix': should not alway appear
• bar 72 hoquetus: mix 100
• bar 73: follow the control of voice in spat
• end of the piece: sfile will play crescendo
• very end: spirale should vanish

Addendum : last performance remarks from Oscar Rodrigues

Dear Serge,I'm so sorry for not replying back about Etymo. It's been really difficult, we are over-scheduled, lots and lots of things happening.I checked my notes, here they are:

The performance was fine, apart from some cues that were triggered incorrectly by the keyboard (the beginning started before the conductor cued).

I had to do some work balancing things out. For instance, the textural rugged sounds (represented by the curved lines) at the beginning were really low in the mix (I think it was in samplor~, but not 100% sure). They're there, but we could barely hear them, so I went into the score and changed some of the amp values.

There's also a problem with the technical rider: the speaker layout is different in your documentation and the patch. Because we had a limited time in the hall for setting everything up, we only found it out during the general rehearsal when we couldn't hear the circles. We had to route everything according to the scheme in the patch, not the technical rider, which cost us a bit of time.

Another issue is the level and balance of the audio content. Luca was operating and I thought many times of the story you told about putting tape in the BCF faders so that he couldn't do higher than a given point :) During the concert he was so enthusiastic that it clipped at a point. Because it is digital distortion, it would be best to level everything down and then raise it in the mixing desk, I think... At least it won't clip in Max.

We were very confused with the click track. Ricordi has it everywhere in the score. And there's no click track!!! It's something they could try and fix because Luca told us the click track version isn't played anymore. I also had the impression that some of the cues are not doing much - they're only there to be triggering the click track, which doesn't exist. I might be wrong, though!

Speaking of Ricordi, it would be very nice if they could include the cue numbers in the score and the electronics + voice part. I had to copy them by hand, one by one. Took about 2 hours of work, which could easily be spared next time. It's time we are not spending working on the patch.

Finally, it's difficult to find out exactly where to trigger some of the vocal processing cues: some of them we had to anticipate, others to delay. This depends on the rhythm of the voice and it's a problem we'll always have, of course. But sometimes, the cues worked better if we triggered them an eighth note before. An example is 52-1.

That's all. Thank you for your help and your work making this possible. We had lots of fun playing and rehearsing Etymo, it was a pleasure :)

Let me know if you need more information.

Best,

Óscar
