Beginning Csound
July 28, 2008 @ NYC Resistor
1 Session, 3 hours, with personalized post-session project with instructor via email.
Cost $75

Csound is the most powerful computer music language in the world, with a direct lineage to Max Mathews' original Music-N languages. The focus of this class will be a synthesis of three topics: The Csound language, synthesizer theory, and composing weird alien music.

Together, we will demystify the assembly-like syntax of the Csound language. We will cover the fundamentals of synthesizer theory, including: oscillators, filters, envelopes, amplifiers and modulation. Finally, we'll tie it all together by composing sounds in the vein of classic Sci-Fi movies.

Hi All,

Menno Knevel was kind enough to report an issue and it revealed a couple of major bugs for JMask. blue users interested in JMask are highly encouraged to upgrade to 0.123.1, available at:

http://www.csounds.com/stevenyi/blue

Thanks very much to Menno!

[fix] - JMask

-Duration was not being set for Mask, Accumulator, and Quantizer; if
a table was used for any values in those modifiers, the duration of
those tables were being calculated as if they were 1 beat long, so
any values generated after 1 beat would pretty much use the value
set at the end of the table; duration is now set correctly

-Dropdowns in UI's did not initialize to the value that the
edited object currently held when first populating interface

Hi All,

I'd like to announce that blue 0.123.0 is now available at:

http://www.csounds.com/stevenyi/blue

The two big features of this release are a completed single-line and multi-line mode for editing/dragging Automation points, as well as a new JMask soundObject. JMask is basically a graphical version of CMask and is mostly 1:1 feature compatible. Also, one nice thing is that with JMask, one doesn't require CMask to be installed, so your project is completely portable across all OS's. Brief documentation can be found here:

http://www.csounds.com/stevenyi/blue/usermanual/html/jmask.html

Users are highly recommended to become familiar with CMask's documentation before using JMask at this time, until JMask documentation can be further expanded upon.

The underlying code for this soundObject is heavily based on the open source version of Andre Bartetzki. Many thanks to him for his generous opening up of the source!

Other changes are listed in the ChangeLog below.

Thanks!
steven

[new] - JMask - new SoundObject based on Andre Bartetzki's CMask; currently
supports same exact features as are available in CMask though using
a graphical user interface to create and configure parameters,
masks, quantizers, accumultators, etc.

[new/updated] - implemented completed single-line and multi-line modes: able
to select time area, then drag selection area to move automation
points for currently edited line in single-line mode, all lines
and soundObjects under selection area in multi-line mode; more
information in documentation

[update] - when rendering, now checks if instruments are muted and if so,
optimize CSD generation and mixer to not generate code for
those channels associated with muted instruments

[fix] - processing of command blocks (i.e. ;[pre]{) trimmed the empty spaces
around lines of text; now leaves formatting in tact

[fix] - Problem with Tempo caused "Audition SoundObjects" to break

[fix] - reenabled cut/copy/paste on NoteProcessorChain editors, fixed to
make buffered noteProcessor be global and can copy/paste in all
noteProcessor editors (i.e. SoundObject, SoundLayer, polyObject),
fixed to make NoteProcessorChain table be max height always of
scrollPane so that right mouse button can always open up popup

documentation

[new] - added initial basic documentation for JMask in the Reference section
for SoundObjects

[new/updated] - Updated "Parameter Automation" in the Concepts section of
the manual with information on the updated Single-Line and
Multi-Line modes

[updated] - Reviewed all reference documentation for NoteProcessors, adding
better examples showing before and after processing

Hi All,

Version 5.08 now released

Downloads at SourceForge.net

Command line and Top level changes:

• Added --csd-line-nums= option;
• Major changes to score error reporting; now accurately reports the line numbers for the chain of inputs for most errors;
• Change to gettext localisation; French and Columbian-Spanish translations available;
• Messages about loading opcode plugins modified so can be suppressed;
• New "no-carry" operator (!) for score language that prevents implicit carrying of p-fields in i-statements;
• Added --syntax-check-only commandline flag (exclusive with --i-only);
• <CsLicense> is accepted as an alternative to <CsLicence>;
• Line numbers of errors in CSDs are now reported using the CSD line numbers instead of the temporary ORC and SCO line numbers *unless* the --csd-line-nums=0 option is given.

Bug fixes:

• pan2: Corrected so it agrees with documentation;
• hilbert had its outputs reversed, now correct;
• <CsVersion> works again according to the manual;
• Fixes in the { and } score looping statements.

new opcodes etc:

• image opcodes;
• pvsbandp and pvsbandr: filters using spectral domain;
• New opcodes powershape, polynomial, chebyshevpoly, pdclip, pdhalf, pdhalfy, and syncphasor;
• New HRTF opcodes by Brian Carty: hrtfmove, hrtfmove2 and hrtfstat;
• jackTransport opcodes to control Jack from Csound.

A number of internal changes:

• gettext version;
• pvsscale: Improved algorithm for SDFT case so no ampltitude variation;
• partikkel: Internal changes to partikkel, interpolation of waveform read and windowing, allowing more precise pitch synchronous granular synthesis.

I'm glad to introduce Surmulot, the integration of all my code for musical composition:
http://www.zogotounga.net/surmulot/surmulot.html

Csound-x users on Windows are encouraged to download the 80 Mb archive at
http://www.zogotounga.net/surmulot/surmulot.zip

When unzipped, you will have Emacs with Csound-x along with µO for Squeak, Csound, Timidity and a few other apps all integrated by scripts and TCP/IP and ready to use. No change is made to the registry, no installation is required, no environment variable is touched.

Hi All,

[released 2008.03.11]

Steven Yi-----------------------------------------------------------------------

blue

[new] - Tempo Editor - allows graphical editing of tempo on timeline for
root polyObject; clicking "Use Tempo" checkbox will enable use of
tempo line and clicking of down arrow will show the tempo for
editing or collapse it to reduce screen space usage; if enabled,
will generate a Csound t-statement to control global tempo; older
project which manually added t-statements in global orc will run
correctly as tempo editor is not enabled by default; right-clicking
on tempo line area when in edit mode will allow option to edit
point values by table or to set the min/max bpm for the tempo line
with option to truncate or rescale line point values for new min/max

[new] - added ability to set Code Text Area background color in Program
Options dialog

[new] - Snap

-Setting render start time and render end time now snap if snap is
enabled; one can modify without snap if snap is enabled by clicking,
then holding down shift, move around (holding shift when clicking
creates a marker, so one should press shift after mouse down)

-Setting automation points now snap x value if snap is enabled;
holding down shift while editing will allow free setting of x value

[new] - added blue variable, equal RENDER_START
value but timewarped if t-statement used

[update] - Tuning NoteProcessor: formerly only held the name of the Scala
file from the .blue/scl directory to use and this file would get
parsed everytime it was used; changed to use same Scale class that
the PianoRoll uses and now loads in content of files and saves it
with the project, making the project more portable.

For older projects, when loading project will be auto-upgraded and
contents of scale will get loaded in. If scale is not found,
results are not predictable and project will likely fail to open.

[fix] - Tempo Mapper

-Fixed timePointer location if tempo used and renderStart > 0

-Fixed timePointer location if two tempo points had same beat time
value (i.e. hard jump in tempo)

-Fixed timePointer location if tempo used and two consecutive tempo
points had same tempo

[fix] - fixed "Convert to BSB" option on Orchestra to copy over UDO's, also
fixed NullPointerException bug in adding parameters after conversion

[fix] - BSB FileSelector was always saving and using absolute file path
instead of using relative path if within directory of project or
in a subdirectory thereof; switched to use relative when possible to
make projects more portable

[fix] - Automation values may not reach end value if ksmps did not equal 1;
added extra parameter note to ensure setting of end values

[fix] - BSB/ObjectBuilder/Effects - Randomization of sliders using
resolution never achieved maximum value

documentation

[new] - Added section on Tempo Editor to Score Timeline section

AlgoScore is an algorithmic graphical sequencer and frontend to CSound where the composer works in an interactive graphical score. Any number of csound instances can be created and take input in the form of events, ftables and control data (through software busses). Each csound instance then renders to audio in a background process, and the audio can be played back throigh JACK or exported to audio file.

AlgoScore is work-in-progress but already quite usable. More information and downloads at http://kymatica.com/algoscore

Hi All,
an updated version of WinXound.Net is now ready for download at:
http://www.ibiart.it/winxound/lastversion.html

New: "Go to line error" button on compiler output window;
New: Improved compiler text output;

Fix: Fixed a serious bug on compiler window thread (output text of the compilation window fails or stops
randomly) - Many thanks to Mark Jamerson and Roberto Doati for the great debug;
Fix: WinXound now save toolbars view preferences;
Fix: Various minor bugs fixed.

[new] - Added "Always Render Entire Project" option to Project Properties
for disk renders; if checked, will render to disk as if the render
end wasn't set and as if rendering from time 0 regardless of what
values are used in render start/end which still affects realtime
playback

[new] - added optional color theming: if blueTheme.properties is found in
the user's .blue directory, values will be used to set blue's colors
for theme; colors normally used are:

primary1=198,226,255
primary2=153,153,204
primary3=204,204,255
secondary1=102,177,253
secondary2=63,102,150
secondary3=38,51,76
black=240,240,255
white=0,0,0

all eight of the above properties must be defined in the
blueTheme.properties if the theme file is to be used; color values
are equivalent to RGB with range 0-255 for each color

[fix] - Mixer was not correctly setting slider positions when loading or
switching to a project

Hi All,

I'd like to announce the 0.121.0 release of blue, available at:

[released 2008.02.12]

I recently wrote a short article on doing physical modeling of a microtonal flute in realtime with csound5. The instruments were designed on linux, but you can change the header to use whatever command line flags you use on your mac or windows setup to run csound5 in realtime.
