ComputationalApproachesToSoundComputational Approaches to Sound Programming and Composing with CSOUND 2 Week workshop at 26 August 2019 - 06 September 2019 This 2 week workshop will introduce participants to elements of composing and programming with CSOUND. CSOUND is a powerful and versatile software synthesis program. Drawing from a toolkit of over 450 signal processing modules, one can use CSound to model virtually any commercial synthesizer or multi-effect processor. CSound transforms a personal computer into a high end digital audio workstation- an environment in which the world of composition, acoustic research and sound-design all join together in the ultimate expressive instrument. The 2 week workshop will cover various compositional techniques with CSound. No previous knowledge of programming or music composition is necessary.

Deconstructing the code Day 2 Deconstructing a CSOUND file The Header Introduction to Score Files and Instrument Files Introduction to GEN routines The SCORE syntax The NOTE list Assignment #2 Re-write scores GEN Routines http://www.csounds.com/manual/html/ScoreGenRef.html Variables i - rate - note rate k - rate - control rate a - rate - audio rate P-Fields ;i P1 - Instrument P2 - Start Time P3 - Duration Assignment #3 Rewrite assignment #1 with P-Fields Assignment #4 Use any one synthesis method of your choice for both the sounds. 1. One Long Sound – Low amplitude 2. One Long Sound – Higher amplitude No breaks in between the sounds Total(40 Seconds) Assignment #5 Use any one synthesis method of your choice for both the sounds. 1. One Long Sound– Low amplitude 2. Short Sounds(broken into equal bits) - Higher Amplitude No breaks in between the first 2 parts Total(40 Seconds) Day 3 Sample Rates Amplitude Clipping Envelopes irate, krate, arate Watching Max Mathews and John Chowning Talk Day 4 Spectral Fusion Assignment #6 Rewrite instruments using spectral fusion. Compose a piece using spectral fusion. Day 5 Value conversions ampdb, cpspch Filters low-pass, high-pass, band-pass, band-reject Assignment #7 Compose Three pieces - each with varying amplitudes. Use Loscil as the primary oscillator. Record sounds with a field recorder and use it as the base sound for LOSCIL Day 6 Assignment #8 Add Filters to any one of the Three pieces that you composed. Assignment #9 Add a tone to Assignment #8 Introducing MIDI Assigning MIDI to CSOUND Day 7 Techniques of Composition - Lecture Introducing REVERB and ECHO Links https://csound.com/get-started.html Csound FLOSS Manual Files: http://files.csound-tutorial.net/floss_manual/ Csound: http://csound.com/download.html Csound Reference Manual: http://www.csounds.com/manual/html/ Csound source code: http://github.com/csound/csound Csound's User Defined Opcodes: http://www.csounds.com/udo/ and http://github.com/csudo/csudo CsoundQt: http://github.com/CsoundQt/CsoundQt/releases WinXound: http://mnt.conts.it/winxound/ Blue: http://blue.kunstmusik.com/ Cabbage: http://cabbageaudio.com/ Most recent (unstable/develop) Csound installer: https://ci.appveyor.com/project/csound/csound/build/artifacts Most recent (unstable/develop) CsoundQt version: https://github.com/CsoundQt/CsoundQt/releases Eastman School of Music CSOUND Tutorials :http://www.ecmc.rochester.edu/ecmc/docs/csound/allan/index.html#TOC Readings Edgard Varèse: in wait for the future https://www.theguardian.com/music/2010/apr/08/edgard-varese-national-youth-orchestra Stockhausen: How Time Passes By http://www.artesonoro.net/artesonoroglobal/HOW%20TIME%20PASSES%20BY.PDF Interview with Max Mathews and John Chowning https://www.youtube.com/watch?v=Hloic1oBfug |
