Luigi Negretti Lanner updates SY.MU.S. & PvocEx Manager
SY.MU.S is essentially a musical sequence builder in Csound score format. Symus includes some Csound code utilities such as an opcode/gen syntax help, plus many orchestra and score examples. PvocEx Manager is a simple window for easy managing of Pvocex by R.Dobson

[12.24.02]
John ffitch releases Public Csound Version 4.23
New Opcodes:
| |
[-] named instruments
[-] user defined opcodes
[-] schedkwhennamed - like schedkwhen but allows named instrument at i-rate
[-] bqrez - A second-order multi-mode filter
[-] SoundFont2-Related Opcodes:
| |
sfload, sfplist, sfilist, sfpassign, sfpreset, sfplay, sfplaym, sfinstr, sfinstrm, sfplay3, sfplay3m, sfinstr3, sfinstr3m, dec, shl, sqr
|
|

[-] Named instruments and user opcodes completely reworked
|
Other Changes:
| |
[-] Realtime MIDI under Windows may now work?
[-] Extract utility corrected; as it was it did not work at all exceptextracting from the start of an audio file
[-] Internal changes related to XINCODE
[-] CoreAudio support in OSX allows -o dac to work. Bug remains with periods on silence or silent sections caused by no events
[-] A new version for OSX with a GUI is available; currently it does not work with realtime audio
|
Windows GUI Changes:
| |
[-] Dither checkbox reinstated in EXTRAS window. No idea why it got lost
|
Opcode Fixes:
| |
[-] madsr failed to do anything; now seems to works as I expect
[-] gettempo now returns correct answer, or at least a consistent one
[-] oscbnk revised
[-] soundin extensively revised, and certainly better
[-] sfont opcodes improved
[-] one change delay in Tck/Tk sliders and controls removed (Unix mainly)
[-] Seeding random numbers from the clock in rand etc is now at higher resolution in Windows and Linux (and probably other UNIX-like systems)

|
|
[12.23.02]
Istvan Varga releases his DeveloperCsound 4.23.2
New Opcodes:
[*] denorm
[*] delayk
[*] vdelayk
[*] new arithmetic opcodes (can be more efficient than expressions):
| |
Add, Sub, sub, Mul, mul, Div, div, vincr, vdecr, vmul, vdiv, Inc, Dec, dec, shl, sqr
|
[*] Internal opcode names like "oscil_kk", "peak_k", "oscilikt_aa", etc. have been all renamed to use a dot instead (thus "oscil_kk" is now "oscil.kk", for example). This avoids conflicts with normal opcode names like "FLpanel_end"
Changes:
[*] Bugs in vco PWM and triangle mode are fixed. Also, amplitude of PWM wave was corrected, and triangle amplitude depends much less on pulse width.
[*] massign can "mute" MIDI channels by assigning to zero or negative instrument number. Useful when midiin opcode is used to parse MIDI events.
[*] bqrez opcode updated to new version from Matt Gerassimoff, also fixed some bugs.
[*] Named instruments can be invoked as opcodes using subinstr-like syntax: a1[, a2[, ... ]] Name p4[, p5[, p6[, ... ]]]
[*] Incorporated new printf opcodes from Matt Ingalls. The new version of "printks" is currently named "sprintks" in order to avoid breaking the original "printks", until the new code is fully tested.
[*] schedule now supports named instruments.
[*] sfont opcodes synchronized with jpff 4.23 version.
[*] Crashes in (some) utilities have been fixed - still needs to be fully cleaned up.
[*] Many internal code changes - see ChangeLog.4.23.2 for details

|
|
|
[11.13.02]
Istvan Varga releases his DeveloperCsound 4.22.5
With:
| |
[+] sources (including documentation), binaries for Linux and Win32 (now optimized for the Athlon, but should run on all Pentium Pro and higher processors), and VIM syntax files
|
Feature HighLights:
| |
[+] Implemented Win32 real-time MIDI input (not tested yet). Devices can be selected with the -M flag (e.g. -M "VirMIDI 1-0"), and if the specified device name is not valid, all available MIDI input devices are printed to the console.
[+] Full-duplex playback/record with Linux OSS interface may work.
[+] New real-time audio code for Linux that uses ALSA (I wrote it for 0.9.0rc1, so newer versions may need some minor changes). The advantages are:
[--] Full-duplex record/playback.
[--] -b (period size) and -B (hardware buffer size) can be controlled separately (allows more control over latency and timing jitter).
[--]Input and output device can be selected by name (for a list of available device names, type aplay -L) using command line flags --pcm-input-device and --pcm-output-device.
[--] Multi-channel (quad etc.) output is supported (assuming that the right device is selected by user; for example, with my SB Live!, the "surround40" device should be used for 4 separate channels).
[--] High resolution sample formats (32 bit integers and floats) are supported (24 bit packed seems to be broken); also u-law but not a-law. Note that with some devices (including the default), floats and long ints can be played (with internal conversion by driver) even on 16-bit soundcards.
[+] Improved rtclock opcode: Now works under Win32. Bug fixed in Linux version. Starts counting from the beginning of Csound performance (this
improves accuracy; the old version had a resolution of about a minute with 32-bit floats, due to the constant offset which was in the order of 1e9 (i.e. this many seconds since Jan 1 1970)).
[+] Built-in support for benchmarking (activated by -m128 flag); prints elapsed real and CPU time at end of orch compile, score sort, and performance.
[+] User defined opcode initialization was made at least 1.5 times faster.
[+] Minor bug fix in subinstr (too many p-fields could result in a crash)

[11.10.02]
Steven Yi releases Blue & Patterns v0.90.5
New Features:
[+] the code repository editor
[+] a new rhino soundObject
[+] a new javaScript soundObject
[+] two new script instruments, pythonInstrument and rhinoInstrument, for writing instruments in python orjavaScript
[+] added drive selection in soundFile browser
[+] added logging message for pythonObject when generating notes
Updated & Fixed:
| |
[-] continuing changes of look and feel: changed tabs, worked with borders, etc.
[-] changed look of external soundObject's bar renderer to not use gradients
[-] created new blue.scripting package, moved PythonProxy class to there and rearchitected as static object
[-] changed OpcodePopup class to static class with reinitialization functions so as to work with code repository
[-] redid BlueSystem object, removed isInitialized() and used static {} block to do initializaiton
[-] reimplemented Instrument interface; uses Editors like soundObjects; InstrumentEditPanel caches editors in the same way as SoundObjectEditPanel, which saves memory and speeds up editting of instruments; new Instrument interface should make it easier to create instrument plugins
[-] added AlphabeticalFileComparator to sort files in the soundFile browser in alphabetical order
[-] soundFile browser now uses double-clicks to initiate selection rather than single click
[-] changed default text of python soundObject and rhinoSoundObject to have a demonstration note
[-] redid ScoreGUI's scrolling: implemented Scrollable on ScoreTimeCanvas, blue.gui.JScrollerBar class to allow to swap out JScrollBar's from JScrollPane which tie into Scrollable objects
[-] removed blue.gui.BlueButton class and made all classes use JButton (remnant from my earliest look and feel experiments)
[-] changed ScoreTimeCanvas to use BLIT_SCROLL_MODE; provides faster response and drawing, fixes bug of not clearing out the backing store when closing out a file (ghost image of old work file)
[-] when calling "Convert to generic score" on a sound soundObject, instrument would be added to orchestra but not displayed until the orchestra split pane was resized; now updates correctly
[-] making copies of a pythonObject did not copy its note processor chain; fixed clone() method in pythonObject
[-] converting to genericScore would not properly grab notes from original soundObject, rescaling and translating the notes;
[-] when zooming the scoreTimeCanvas, canvas would not resize properly horizontally; fixed logic in checkSize() method
[-] overrided paintChildren() method in ScoreTimeCanvas to get Marquee drawing on top of children
