Csound "front end" 1.0
Available From:
ftp://mills.edu/ccm/csound.ppc
=======================================
changes from 3.484 (front end 1.0b)
=======================================
Perf:
- handful of bug fixes in fFitch code

passed from front end) is now saved for default
for command line-only mode..
- dos/mac/Unix files all recognized!!!!
(thanks John!!)

polling for user events.

.0000001 less than number..
Front End:
- MIDI Pedal Threshold option removed so:
- Removed MIDI Dialog - put terminate option
back in Options and Save MIDI to file
in General prefs.
- Created option to use extensions in output
file. Made all extensions 3 letters as
per Richard B's request.
- Made Buffers Dlog Modeless (and fixed bugs
that this created..)
- Made "Reset All" Close all dlogs as well.
=======================================
This needs testing! No doubt things will not
work. When you find a potential bug don't
hesitate to email csound-dev@mills.edu
so we can fix the problem. (however, you may
first want to read the "known bugs" below)
If this "beta" version proves stable enough,
we will put out source
NOTE: You do NOT need to remove old versions
from your hard disk anymore. Csound/Perf now just
looks for the most recent(ly created) version of
its partner and talks to that one. If this beta
version is not working properly for you, you will
need to remove both "CSound" and "Perf" applications
from your computer to use older Csound versions.
=======================================
KNOWN BUGS/INCOMPLETE FEATURES
=======================================
Documentation and Examples:
- has not yet been brought up todate.
Perf:
- Sometimes playback may cut off the last fraction of a
second of the sound or (more likely and less serious)
"hangs" for a moment after playback or when user hits
the transport then might give a slight "sputter"
(problems with new OS -- will need work to fix)
- Transport is sometimes sluggish.
- RT Audio has not been tested!!!
- PostScript file write of graphics either does not
work or writes only the first table???
- cant copy from listing window/Edit menu disabled
- Progress/Profile feature currently disabled
- rescale crashes for files with no header option
- many MIDI problems
- wg-opcodes not really working (new bug)
Front End:
- Reset All Options/Prefs does not update open windows
- Default Dirs by button flashes when appears, and if
dialog is already open stays in background.
- If Direct Rendering and you start CSound,
project window doesnt open by default.
- "Synthesizing" output file name automatically might
sometimes replace a filename user already typed in.
(could make this an option..)
=======================================
RECENTLY NEW CHANGES/FEATURES
=======================================
Perf:
- reconciliation with canonical(fFitch) code
(with tons of changes/bug fixes -- see his release notes)
- changed about box and version numbers
- changed default window placements

- listing file now created and still have output window display
- added file and edit menus
- various flag letter changes to be compatible with canonical

Front End:
- make listing file "double-click-able" to open
with the text editor and fixed bugs with selecting
directory to be created.

only shows orc/sco/output and generate button.
- made a small button (lower/middle left) to "zoom"
in and out of this view mode
- added a "View Files in Text Editor" command in the
File menu.

graphic placements all around.

SFDIR
- changed PVANAL to Max 65536 frame size and default hopsize
to 64
- added progress/profile window so:
- eliminated "heartbeat" option
- made 32-bit float selection and SDII and WAV selection
enable/disable popups according to whats possible.
- chaged color
- reworded "rescale" options, "render" and "sample size"

- added unsigned char sample size
- moved "Terminate on MIDI track end" option to MIDI dlog
- removed "Scot" option as it is no longer supported

=======================================
NOTE TO DEVELOPERS AND USERS OF
OTHER FRONT END "LAUNCHERS"
=======================================
We have completely consolidated our sources and canonical 3.484 source.
To do this, we had to change some of our Mac-Specific command
line flags. If you are a developer of a front end "launcher"
that uses "Perf" you may have to change your application to
accommodate. The Mac-Specific flags are now:
-X fnam Sound File Directory
-q fnam Sound Sample-In Directory
-Q fnam Analysis Directory
-V N Number of chars in screen buffer for output window
-E N Number of tables in graphics window
-p Play after rendering
-e Rescaled floats as shorts to max amplitude
-w Record and Save MIDI input to a file
-y N Enables Progress Display at rate N seconds
or for negative N, at -N kperiods
-Y N Enables Profile Display at rate N in seconds
or for negative N, at -N kperiods
-- fnam log output to file ("listing" file)
=======================================
TO DO (short term)
=======================================
- save window locations
- save user options in pref file rather
than the application
- enable progress/profile (get code from dave)
- progress/profile on utils
- add user able to set creator of generated files
- cancel on score generation
- get perf to stop w/ cmd-period
- get perf playback play/stop with space bar?
- make score optional
- get rescale code cross-platform
- compile 68k version
- add a "sndinfo" button next to outputfile
- have option to not show output window at all
(only to listing)???
- have project/orc files differences transparant
=======================================
TO DO (long term)
=======================================
- separate windows for dispfft and display
- try to patch "dribble" output to a file to
output in the front end instead
