| - | ====== OpenMusic training workshop @CIRMMT ====== | ||
| - | |||
| - | **May 29th - June 1st, 2012**\\ | ||
| - | 10am-4pm\\ | ||
| - | **[[http://www.cirmmt.mcgill.ca/|CIRMMT]]**, Centre for Interdisciplinary Research in Music Media and Technology, Montréal, QC, Canada. | ||
| - | |||
| - | [[http://www.cirmmt.mcgill.ca/activities/workshops/training/om/]] | ||
| - | |||
| - | You will find in this page links and information related about our workshop sessions. | ||
| - | |||
| - | |||
| - | ===== Downloads and installation ===== | ||
| - | |||
| - | In order to install the latest OM version (**6.5.1**), go to the [[http://repmus.ircam.fr/openmusic/download|OM download page]] in the OM website and follow instructions. | ||
| - | |||
| - | __Mac users only__: If this is your first installation, you will need to install //MidiShare//. MidiShare is the library used by OM to manage MIDI data and rendering. For technical reason it can not be included with OM pack and needs separate install. | ||
| - | Depending on your OS configuration, Midishare 1.93 or 1.92 may be tested (we shall do it during the first workshop session). Links band instructions are also on the OM downloads page. | ||
| - | |||
| - | |||
| - | **Note:** Some problems have been reported by users of OM 6.5.1 after MacOS Lion upgrade. Annoying crashes may happen at dragging objects, requiring complete restart (and possible data loss). I am currently working on it, and integrated changes in a **beta release** (MacOS, Intel only) which you can temporarily find [[http://recherche.ircam.fr/equipes/repmus/bresson/cirmmt/|here]] during the workshop. Do not hesitate to [[om-dev@ircam.fr|report]] any problem. | ||
| - | |||
| - | ===== Getting help and support ===== | ||
| - | |||
| - | If you want to explore OM by yourself, you may find help at these different places. | ||
| - | |||
| - | * The [[http://support.ircam.fr/forum-ol-doc/om/om6-manual/|online user manual]] (also accessible in OM from the //Help// menu) is a relatively complete documentation about all features and programming concepts of the OM environment. (Noet that this manual does //not// include external libraries). | ||
| - | |||
| - | * The **function and class reference** is accessible in OM from the //Help// menu and provides a basic documentation of all referenced objects and functions. Type 'd' in an OM patch to access directly the reference page corresponding to a selected box. | ||
| - | |||
| - | * In patch and other OM editors, the //Editor command keys// in the //help// menu (also accessible with 'H' keyboard shortcut), can be a useful reminder of the principal actions and shortcuts. | ||
| - | |||
| - | * See the [[http://www.lispworks.com/documentation/HyperSpec/Front/index.htm|Common Lisp specs. and reference]] for the Lisp tools and functions. | ||
| - | |||
| - | => **Subscribe the the [[http://repmus.ircam.fr/openmusic/contact|OM mailing list]] to get support, advices and share your experience and problems with the OM user community and developers.** | ||
| - | |||
| - | ===== Hints / Panic ===== | ||
| - | |||
| - | * When **a box can not draw anymore** because of a wrong input and a message errors appears every time you click or redisplay: hide the "miniview", by selecting the window and typing upper case 'M' (show/hide //all// front window miniviews). Delete the box and create a new one, just to be sure.. | ||
| - | |||
| - | * When you're in trouble with the **system Terminal**: Try to type **:top** to return to the top level and get the control back on the OM user interface. Do not forget to save your work. Consider a fresh restart. | ||
| - | |||
| - | * When an evaluation seems never to end (Listener printing "Running" forever): Try to **abort** the process (Listener window, menu //Lisp/Abort// or CMD+'A'). | ||

| - | |||
| - | ==== Patches and topics covered ==== | ||
| - | |||
| - | === OSC (OpenSoundControl) and UDP networking === | ||
| - | |||
| - | |**How to send/receive messages to/from other applications or other computers** \\ \\ Download the patch: {{:bresson:workshop:osc.omp.zip|}} | {{ :bresson:workshop:osc.png?550 }}| | ||
| - | |**A Max/MSP communication example** \\ \\ In the patch we also show how to use variables to collect data sent by other applications to OM. For this purpose we used a **Lisp function** and the Lisp variable definition and access tools (SETF, etc. -- see more on the [[http://www.lispworks.com/documentation/HyperSpec/Body/m_setf_.htm|Lisp specification]]). \\ \\ Another solution would have been to use OM global variable in OM. See more [[http://support.ircam.fr/forum-ol-doc/om/om6-manual/co/GlobalVariables.html|in the OM user manual]]. \\ \\ \\ Download the Max5 patch: {{:bresson:workshop:send-receive.maxpat.zip|}} | {{:bresson:workshop:osc-max.png?500}}| | ||
| - | |||
| - | === Audio Tools === | ||
| - | |||
| - | |**Sound montage, mixing and processing.** \\ \\ Record sound into an //sound// box.\\ Sound processing boxes: //sound-seq//, //sound-cut//, //sound-save//... \\ \\ Download the patch: {{:bresson:workshop:audio.omp.zip|}} | {{ :bresson:workshop:audio.png?400 }}| | ||
| - | |**An example of audio iteration.** \\ \\ In this second patch we embedded the audio functions in an iterative patch (//omloop//) which selects a random position in the file and cuts a small extract (//sound-cut//), repeats this process a number of times, and appends the extracts into a single sound (//sound-seq//). In order to implement this loop, we used the //accum// box instead of the //collect//, so as not to collect the extracts into a list, but defined our own "collection" procedure using //sound-seq//. \\ \\ Download the patch: {{:bresson:workshop:audio-loop.omp.zip|}} | {{ :bresson:workshop:audio-loop.png?200 }}| | ||
| - | |||
| - | === Csound synthesis === | ||
| - | |||
| - | |||
| - | => [[http://www.csounds.com/|Csound]] website. [[http://sourceforge.net/projects/csound/files/csound5/|[download page]]]. | ||
| - | |||
| - | |[[http://www.csounds.com/|Csound]] introduction and install... \\ Read more about Csound [[http://www.csounds.com/docs|HERE]]. |{{:bresson:workshop:csound-intro.pdf|}}| | ||
| - | |**Csound in OM / OM2Csound** \\ \\ See the //OM2Csound// tutorial patches (//workspace// window, menu //Help/Import tutorial patch/Libraries/OM2Csound//) to see how to **run and edit Csound code in OM (tutorial patch 01)** and **generate Csound code in OM patches (tutorial patch 02)** and **connect to the OM score objects (tutorial patch 4)**.|{{:bresson:workshop:om-csound.png?340}}{{:bresson:workshop:om2csound-score.png?400}}| | ||
| - | |||
| - | |||
| - | === OMChroma === | ||
| - | |||
| - | **OMChroma** is a library for the high-level control of sound synthesis in OM. It can be used to control Csound synthesis and Chant synthesis. OMChroma is structured around a principal data structure similar to a bi-dimensional matrix (a subclass of the OM object //class-array//). During this workshop session we went through the very basics of OMChroma and saw how to use these matrices to control Csound synthesis processes. | ||
| - | |||
| - | The OMChroma library provides a set of synthesis //classes// (or 'types' of objects), each corresponding to a particular Csound instrument (**see OMChroma embedded reference for an overview of the classes** -- right-click + //Documentation// on the library icon, or typing 'd' on the different OMChroma objects from your OM patch). \\ \\ The general synthesis function //**synthesize**// will allow to generate an adequate Csound //score// from the OM matrix, and perform the synthesis. | ||
| - | |||
| - | |||
| - | => [[http://www.csounds.com/|Csound]] website. [[http://sourceforge.net/projects/csound/files/csound5/|[download page]]]. | ||
| - | |||
| - | |||
| - | {{:bresson:workshop:csound-matrix.pdf|}} | ||
| - | |||
| - | Download the patches: {{:bresson:workshop:omchroma.zip|}} | ||
| - | |||
| - | |OMChroma classes are initialized with default parameters: just connect to //synthesize// to run and render one single component. \\ \\ The first patch uses ADD-1, the basic 'additive synthesis' class. \\ \\ Use the 'optional' inputs to show and modify the different parameters.|{{ :bresson:workshop:add-11.png?350}}| | ||
| - | |If you change the number of components (**numcols**), you will be able to set lists of values for each synthesis parameters, and start designing more complex sounds with the same matrix. \\ \\ //e-dels// (for 'entry delays') and //durs// (durations) allow you to control the internal time structure of the sound.|{{ :bresson:workshop:add-12.png?400}}| | ||
| - | |After ADD-1, the second patch shows two other synthesis examples: the classes 'FM-1' and 'PLUCK-1'.|{{ :bresson:workshop:fm-pluck.png?400}}| | ||
| - | |The **action-time** input allows to set a global offset to the matrix (or 'synthesis event'). By connecting a list of matrices to //synthesize//, you can therefore create larger-scale time structures with synthesis events (possibly using different classes / synthesis techniques).|{{ :bresson:workshop:events.png?480}}| | ||
| - | |||
| - | === Spatialization and OMSpat === | ||
| - | |||
| - | => Download the **Spat** renderer and //OM-Spat-AddOns// (Mac only) in IRCAM Forumnet [[http://forumnet.ircam.fr/363.html|"Reasearch pack downloads"]] (special access for workshop participants, valid until June 30th).\\ | ||
| - | |||
| - | |New objects for the manipulation of curves and trajectories: **BPC**, **3DC**, **3D-trajectory**.|{{ :bresson:workshop:trajectories.png?250 }}| | ||
| - | |Examples of algorithmic generation of trajectories. \\ \\ The coordinate-system conversion functions in //Basic Tools/Geometry// can be very useful.|{{ :bresson:workshop:spirale.png?260 }}| | ||
| - | |Rotation of a 3DC and application in an iterative process (//mapcar//). \\ \\ The BPC-lib and 3DC-lib objects allow to collect lists of BPCs or 3DCs. \\ \\ Download the patch: {{:bresson:workshop:bpc-and-trajectories.omp.zip|}}|{{ :bresson:workshop:rotations.png?380}}| | ||
| - | |**OM-Spat** and the **spat-matrix** object allow to represent spatial scenes. As for sound synthesis matrices, here every component represents one source and its different spatial parameters. \\ \\ The spatial scene can be saved as an SDIF file, or rendered to a multichannel audio file with the **Spat renderer**.\\ \\ Download the patch: {{:bresson:workshop:om-spat.omp.zip|}}|{{ :bresson:workshop:om-spat.png?480 }}| | ||
| - | |Load the SDIF file in the **Spat-SDIF-Player** application (MacOS only) to control its contents streaming via OSC/SpatDIF messages. \\ \\ [more on the [[http://spatdif.org/|SpatDIF]] format]|{{ :bresson:workshop:spat-sdif-player.png?480 }}| | ||
| - | |The OSC/SpatDIF messages can be received for instance in **SpatDIF-Viewer** (simple 3D display) or in latest **Spat 4** versions for Max/MSP via //udpreceive// the //spatdif-to-spat// object (remember that only one application at a time can bind the UDP pro at a time, and set the send/receive ports accordingly in the different applications).|{{ :bresson:workshop:spatdif-viewer.png?300 }}| | ||
| - | |||
| - | **OMPrisma** is an other library for sound spatialization based on Csound and the OMChroma framework. It allows other interesting and powerful applications, such as performing //spatial sound synthesis// by merging synthesis and spatial parameters in a common control and rendering processes. | ||
