SSMN-RENDERING-ENGINE

©SSMN/ICST/ZHdK/SNF

This is an introduction to the SSMN – RENDERING – ENGINE it’s primary function is to permit the user to experience the SSMN Spatialization notation symbols as indicated in various software by auditioning and viewing audio placement and trajectories in a 2D or 3D radar projection.

 

 

Audience Composers of instrumental music utilizing spatialized live-electronics

Goal In order to enrich the composer workflow, the spatial instructions will be rendered onto the audio system during playback.

What the SSMN-Rendering-Engine cannot do : Be a performing-tool. Have an exact control about the spatial instructions. Have special support for electroacoustic music.

! You need to have initially “JackPilot.app” and “qjackctl.app” !

 

Info about Jack —> installing JackOSX then staring_Jack OSX

 

Software installation: go to http://ssmn.icst.net/ssmn-toolkit/(1) download the following Applications from SSMN-Site. (2) unzip and follow the installer instruction. JackOSX.app —> needs restart ! (3) be sure that all Tools are in your /Applications Folder ! (4) double click the “start-ssmn_jack.command”

(1) Audio-Input section : A: “VST/AU Sampler” B: extern (Jack) inputs C: Sample-player (1 – 16ch) D: audiotest with noise (2) Audio-Routing section: A: choose the format (default “ambisonic”) B: choose your midi-controller C: open bpatches (3) Audio-Rendering section: A: “ambisonics-decoder” B: “speaker delays” C: “output-module” D: “switch auxiliary” E: “output-meters” F: “Initialization” G: “Audio on/off” (4) open – “settings-bpatches” (5) open the “speaker-configuration” for the “ambisonic-decoder” (6) osc-(opensoundcotrol) router (7) set the unit-for the distance (8) Radar displays the trajectories

(1) click – “DSP” it opens a new window —> (2) where possible, replicate the identical configuration as in “Jack Pilot” !! (3) verify that here “Jack Router” is selected! (after that you can close the “Audio-Status” window.) (4) click the button (speaker icon) for “Audio” activation

(1) click “open-speakers” : a new window pops up. (2) choose your “speaker-setup” e.g. “quadro” –> click “close-speakers” for closing the window (3) change Radius (4) write & read you on setup as a xml-file

(1) press “open-settings” . (2) press “open-distance”. (3) choose the “parameters”. (4) set the “unit per distance” (default 10.) [in the graphic you can see only the first 5 unit-steps]. (5) save –> the “Distance-parameters”. (shift&click)

(1) click “open-sampler” —> this open’s the “ssmn-instrument” (2) choose your “sampler-instrument” (default “ARIA-Player”) (3) choose an instrument (ex. Flute Solo) (4) verify that ch-1 is left and ch-2 is right ! (5) opens the “random-midiplayer” for testing. —> choose midi-channel (1-16) (6) play test on/off

(1) open “audiotest” (2) step thru the audio-channels (3) auto-step from ch-0 to ch-n (4) audio on/off (5) volume

The “Tape-player” plays “Bformat3” files.

(1) open the “input-volume” and “master-volume”. (2) choose your “midi-controller”. (3) double-click in the “Radar” and set a “point” (nr.1 = Flute ch-1) –> move the “source-point” (4) click “speaker-button” to activate the audio-driver.

(1) initial –> midi-device SSMN ist ein OpenSource Projekt und hat in MuseScore Bei der „SSMN RENDERING ENGINE“ handet es sich um eine in MAX 6.0⁠1 programmierte Standalone – Application. Diese Application erlaubt es den Komponisten und Interpreten die SSMN -Symbole und SSMN-Taxonomie, in Realtime zu kontrollieren und zu testen. Aus den Erfahrungen aus den Arbeiten in der Praxis , zusammen mit den „ICST-Artist in Residency“, Komponisten, Chreographen und Interpreten, wurde dies Frage der Kontrolle und realtime Versuchen sehr schnell ein unabdingbarer Fakt. Aus den vorausgegangenen Forschungen in Ambisonics war der Schritt gegeben, innerhalb des „SNF-Projektes“ diese „Rendering-Engine“ zu programmieren. choose –> the midi-controller

(1) open “osc-dp” (2) this alows you to start and stop “MuseScoreSSMN” together with the DAW “Ardour 3” or ©2012 “Digital Performer 8” from http://www.motu.com (3) Not yet work

(1) open “open_auto-move” –> for testing the movements (2) set the A: “speed” in “stepsize” –> B: rotate or random” —> C: start / stop

(1) open Region-range (2) connect to “source” or to “speakers” (3) choose the “region” – dimension

(1) open the “Transform”- Patch (2) choose air-absorption or doppler-effect ( this effects are allways for all sources at the same time !) (3) automation (4) Mirror – Effect

(1) open “settings” (2) open “osc-router” (3) save your one configuration. (4) default “presets” click for choose.

(1) open “audio-routing” (2) choose input <—> output

5.1 surround

Please download and install from “Ambisonic Studio” . OBORO plug-ins “3b2sic.component” for playing in 5.1 surround is a special set of plug-ins that were developped for a workshop given by Florian Grond on the use of “simple algorithmic patterns in order to control musical parameters, such as rhythm, pitch, harmony and spatial positioning of sounds”. The workshop took place at OBORO in December 2008 (PDF). © Daniel Courville, 2007-2012

(1) open the “plugin-module” (2) choose “3b2six.component” (/Library/Audio/Plugins/components/) (3) open the PlugIn-GUI

(1) open the “binaural-engine” (2) chosse a “htrf-cue” (3) Virtual-configuration 2D

This application is programmed with Max 6.0 by “cycling74.com” and some modules by “jamoma.org” Thanks to Daniel Courville for his AU/VST Plugins : http://www.radio.uqam.ca/ambisonic Many thanks to the ICST-Team for the “icst-ambisonics-tools” in particular to “jasch” for his “jasch-tools“
