# Line 1  Line 1 
1  Version CVS HEAD (?)  Version SVN trunk
2      * general changes:
3        - removed 2 GB limitation when loading a gig or DLS file
4        - using now native integer size where appropriate
5        - fixed minor issues with man pages (patch by Debian maintainer)
6        - fixed various spelling mistakes (patch by Debian maintainer)
7        - Added new "Serialization" framework (and equally named namespace)
8          which allows to serialize and deserialize native C++ objects
9          in a portable, easy and flexible way.
10        - print compiler warning if no RTTI available
11        - Fixed potential crash in command line tools gig2stereo, korg2gig,
12          korgdump and sf2extract.
13    
14      * src/gig.cpp, src/gig.h:
15        - fixed bug in Script::SetGroup: the script chunk wasn't moved
16        - fixed compilation error with clang 3.4
17        - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
18          as one single monolithic gig file. In case .gig file is >= 2GB expect a
19          large monolithic file, otherwise if .gig file is < 2 GB check for
20          "extension" files (.gx01, .gx02, ...) instead.
21        - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
22          if there were dimensions after the velocity dimension: it only created
23          valid velocity tables for cases of dimensions lower than the velocity
24          dimension.
25        - added new method Sample::VerifyWaveData() which allows to check whether
26          a sample had been damaged for some reason
27        - Fix: samples' CRC checksums were damaged on file structure changes.
28        - Fix: samples' CRC checksums were misordered when a Sample was deleted.
29        - Added new method Sample::GetWaveDataCRC32Checksum().
30        - Changed default value of EG2Release (filter release time) to 60s.
31        - Instruments' default pitch bend range is now +-2 semi tones.
32        - Fixed CRC checksums being wrong sometimes.
33        - Fix: method File::AddContentOf() did not clone script groups and scripts
34          of passed original file.
35        - Added support for serializing & deserializing DimensionRegion
36          objects (and crossfade_t and leverage_ctrl_t objects).
37        - Added enum reflection API functions for retrieving enum declaration type
38          information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
39        - Exception class now has a variadic constructor which allows to add
40          textual format specifiers like with printf().
41        - On unknown leverage controller exception: show precise unknown leverage
42          controller number found.
43        - Ignore invalid leverage controller types and just show a warning on the
44          console instead of throwing an exception.
45    
46      * src/DLS.cpp, src/DLS.h:
47        - Sample: wave pool offsets are now 64 bits (to allow support for files
48          larger than 4 GB).
49        - Exception class now has a variadic constructor which allows to add
50          textual format specifiers like with printf().
51          
52      * src/RIFF.cpp, src/RIFF.h:
53        - added support for RIFF files larger than 4 GB, by default the required
54          internal RIFF file offset size is automatically detected (that is RIFF
55          files < 4 GB automatically use 32 bit offsets while files >= 4 GB
56          automatically use 64 bit offsets), a particular offset size can be forced
57          with a new option added to the RIFF File constructor though
58        - when saving a modified, grown RIFF file, the temporary file size during
59          Save() operation will no longer be larger than the final grown file size
60        - Exception class now has a variadic constructor which allows to add
61          textual format specifiers like with printf().
62    
63      * src/Serialization.cpp, src/Serialization.h:
64        - Archive: Added method isModified().
65        - Archive: Added method setAutoValue().
66        - Archive: Added method setIntValue().
67        - Archive: Added method setRealValue().
68        - Archive: Added method setBoolValue().
69        - Archive: Added method setEnumValue().
70        - Archive: Added method valueAsString().
71        - Archive::rawData(): Automatically re-encode new raw data stream if
72          archive had been modified (i.e. by remove(), setAutoValue(), etc.).
73        - Object: Added method memberByUID().
74        - Object: remove() method is now protected.
75        - Archive: Added method removeMember().
76        - Archive: Added methods name() and setName().
77        - Archive: Added methods comment() and setComment().
78        - Archive: Added methods timeStampCreated(), timeStampModified(),
79          dateTimeCreated() and dateTimeModified().
80        - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
81        - DataType: Implemented demangling C++ type names (for methods
82          asLongDescr() and customTypeName(bool demangle=false)).
83        - Archive::setAutoValue(): Handle human readable boolean text
84          representations like "yes", "no", "true", "false" as expected.
85        - Exception class now has a variadic constructor which allows to add
86          textual format specifiers like with printf().
87    
88      * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
89        - improved output of non-ascii characters in usage messages
90        - fixed printf format strings
91

99        - additionally print RIFF chunk file offset and RIFF chunk size of sample
100          data
101        - added and implemented new parameter "--verify" which allows to check
102          the raw wave form data integrity of all samples
103        - added and implemented new parameter "--rebuild-checksums" which allows
104          to recalculate the CRC32 checksum of all samples' raw wave data and
105          rebuilding the gig file's global checksum table (i.e. in case the
106          file's checksum table was damaged)
107        - print samples' CRC32 checksums
108    
109      * src/tools/gigextract.cpp:
110        - Fix: if sample name contains a path separator (slash or backslash) then
111          replace them by a minus sign to avoid file system issues.
112    
113      * src/tools/gig2stereo.cpp:
114        - Also merge mono sample pairs with non matching loop information if
115          argument --incompatible was given.
116    
117      * packaging changes:
118        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
119          auto detect whether it (sh/c)ould output its messages in color.

153          (.KMP and .KSF files)
154    
155      * AKAI file format:
156        - Added Linux/POSIX ported version of libakai. Note that libakai is released
157          under LGPL terms while libgig is released under GPL terms. To handle this
158          license difference appropriately the AKAI support part is built as
159          separate DLL (.so file).

161          any exotic third party libraries.
162        - Fixed various compilation errors for Windows.
163        - POSIX fix: open() requires third (mode) argument if used with O_CREAT

165    
166      * src/gig.cpp:
167        - bugfix: VCF velocity dynamic range and VCF velocity curve
168          weren't saved correctly

176          wrong textual group name
177        - added new method File::AddContentOf() for merging .gig files
178        - GIG FORMAT EXTENSION: added additional MIDI controllers for leverage
179          controller types (only works with LinuxSampler & gigedit, will not
180          work with Gigasampler/GigaStudio)

196          new one being dropped after save operation and the gig file being tainted
197          (chunks at wrong location in the RIFF tree).
198        - Added new method Instrument::MoveTo() which allows to rearrange the order
199          of instruments within the same gig file.
200    
201      * src/DLS.cpp, src/DLS.h:
202        - added new method File::GetFileName()

223          later on without passing a file name
224        - added new method File::IsNew()
225        - added support for loading RIFF-like files with a bit different layout
226          than "real" RIFF files (used for KORG format support)
227        - added new method Chunk::GetFile()
228        - added new method Chunk::GetLayout()
229        - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one
230          allows to move a subchunk within the current List, whereas the new 2nd
231          one allows to move the subchunk from the current list to another list
232        - POSIX: only assume -1 result value as error on open() calls
233        - POSIX: show operating system's error reason if opening a file failed
234        - Added support for custom progress notification while saving to RIFF file.
235        - Fixed embarrassing old bug: POSIX read() errors were never detected on
236          Chunk::Read() calls due to signment incompatible variable.
237        - Cleanup of an old DLL binary backward compatibility hack.
238    
239      * src/gigextract.cpp:
240        - export sample loop, unity note and fine tune with libsndfile
241

256        - bugfix: removed another iterator invalidation in DeleteSample
257        - bugfix in Sample::LoadSampleData*(): reset sample read position to
258          sample start before trying to (re)load sample data from file (#82)
259        - bugfix: EG3 depth parameter was not saved correctly
260        - fixed crash which occured when streaming a gig sample with
261          bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
262    
263      * src/RIFF.cpp, src/RIFF.h:
264        - bugfix: saving to the same file after the file size had been
265          increased made the file corrupt (#82)
266        - bugfix: refuse Chunk::Read() in case chunk has just been added, that
267          is not written physically yet (#82)
268        - bugfix: saving to the same file after the file size had been
269          decreased sometimes also made the file corrupt!
270        - bugfix: undefined behavior (e.g. endless loop) when opening zero
271          length files, now throws a RIFF::Exception instead (fixes bug #121)
272        - bugfix: destructor for base class RIFF::Chunk accessed members
273          of derived class RIFF::File, which is bad, and caused crashes
274          when using Visual C++
275        - bugfix: files that contain zero length RIFF lists were not read
276          correctly (fixes #127) (bug was introduced 2009-03-13)
277

279    
280      * src/RIFF.cpp, src/RIFF.h:
281        - avoid Windows to perform unnecessary file stream caching which would
282          decrease disk streaming performance on Windows systems otherwise
283    
284      * src/gig.cpp, src/gig.h:
285        - added File::SetAutoLoad() and File::GetAutoLoad() for allowing
286          applications to retrieve very superficial informations like amount of
287          instruments and their names in a very fast way
288

313          happened when gig::Group informations were accessed before
314        - fixed write support for big-endian systems

318          instrument constructors
319        - clear unused fields when saving samples and regions
320        - fixed write support bugs: v3 dimension limits and chunksize

329          definition are now saved
330        - added constants for gig file versions
331        - write support: the 3crc and einf chunks are now created or
332          updated when a file is saved (3crc contains sample checksums,
333          einf contains file statistics)
334        - write support: DLSID is now generated on the file and the
335          instruments
336        - write support: improved the default values for dimension region
337          parameters
338        - more write support fixes: crossfade parameters were not saved,

340          when dimensions were added or deleted, v3 wave pool offsets were
341          not saved correctly
342        - write support: 24 bit samples can now be written
343        - write support: version 3 is now the default for new files
344        - more write support fixes: the 3ewg chunk is now bigger for v3,
345          dimension regions without mapped samples are now allowed, 3gnl

347          where incorrectly saved due to an operator precedence mistake
348        - DeleteSample now removes all references to the deleted sample
349        - AddDimension now copies all parameters from existing dimension
350          regions and also makes sure that the samplechannel dimension is
351          placed first in the list of dimensions.
352        - added method GetParent() to class 'DimensionRegion', which returns its
353          parent Region
354        - fixed Instrument::UpdateRegionKeyTable() method which did not reset
355          unused areas
356        - added various setter methods to DimensionRegion class which take care
357          of updating lookup tables / caches.
358    
359      * src/RIFF.cpp, src/RIFF.h:
360        - added File::SetByteOrder method
361        - Windows fix: saving a new file didn't work
362    
363      * src/gigdump.cpp:

366    Version 3.1.1 (24 Mar 2007)
367    
368      * packaging changes:
369        - ported to Windows using native Windows functions for file IO
370          (provided Dev-C++ + mingw project file)
371        - only export relevant files to Doxygen API documentation
372    
373      * src/gig.cpp, src/gig.h:
374        - custom velocity splits now works for gig v3 files too
375        - added support for custom splits points for other dimensions than
376          velocity (gig v3 feature)
377        - added "smart midi" and "round robin keyboard" dimensions
378        - added new method File::DeleteGroupOnly() which only deletes the given
379          group but moves all its members to another group, the other method,
380          that is File::DeleteGroup() now removes not just the group, but also
381          all the samples that belong to that group
382        - fixed crash which occured on interfering File::DeleteSample() and
383          File::GetNextSample() calls (due to iterator invalidation)
384        - fixed group names which were not saved

389          when used from Instrument::AddRegion
390        - when saving, override the gig::Regions sample reference simply by
391          the region's first dimension region's sample (avoids an exception
392          when trying to save a new instrument)
393        - fixed AddDimension() method which did not fill out all mandatory
394          dimension definition fields
395

399          causing an exception when trying to save a new instrument
400    
401      * src/RIFF.cpp, src/RIFF.h:
402        - fixed RIFF::Chunk destructor which did not unregister previously
403          resized chunks, leading to a "zero size chunk" exception when
404          File::Save() was called
405        - added List::MoveSubChunk method
406    
407    Version 3.1.0 (24 Nov 2006)
408    
409      * packaging changes:
410        - changed deprecated copyright attribute to license;
411          added ldconfig to post-(un)install steps on libgig.spec (RPM)
412    
413      * src/gig.cpp, src/gig.h:
414        - added support for more than one set of custom velocity splits
415          inside a region (for example different velocity split levels for
416          pedal up and pedal down)
417        - sample loop parameters are now taken from the DimensionRegion
418          instead of the wave chunk
419        - keyswitching dimension is changed from split type "normal" to
420          "bit"
421        - real support for 24 bit samples - samples are not truncated to
422          16 bits anymore
423        - support for reading of ".art" files. (Merging of .art and .gig
424          files are not implemented yet.)
425        - several fixes for the write support
426        - support for sample groups added
427    
428      * src/DLS.cpp, src/DLS.h:
429        - support for reading of ".art" files
430        - removed incorrect use of memccpy in the write support (patch by
431          Jeremy Kerr)
432        - several fixes for the write support
433    
434      * src/gigextract.cpp:
435        - real support for 24 bit samples
436    
437      * src/gigdump.cpp:
438        - print global file informations
439        - print sample groups
440    
441      * general changes:
442        - added CPPUnit test cases (at the moment primarily for automatic check
443          of Gigasampler write support)
444    
445    Version 3.0.0 (28 Apr 2006)
446    
447      * general changes:
448        - added write support (that is for creating and modifying RIFF, DLS and
449          gig files)
450        - loading DLS and gig files is now much more permissive, DLS and gig
451          files are now loaded even if mandatory RIFF chunks are missing
452        - fixed some memory management errors, one of them was causing a
453          crash when a multi-file gig was deallocated
454    
455      * src/gig.cpp, src/gig.h:
456        - fixed the GetVelocityCutoff function, it wasn't always using the
457          VCFVelocityScale parameter when no cutoff controller was defined
458        - support for the gig v3 feature to have a number of dimension
459          splits not equal to a power of two
460        - added write support (highly experimental)
461    
462      * src/DLS.cpp, src/DLS.h:
463        - fixed loading of Articulation Connections (<artl> list chunks were
464          seeked instead of ordinary <artl> data chunks)
465        - added write support (highly experimental)
466    
467      * src/RIFF.cpp, src/RIFF.h:
468        - added write support
469        - Chunk::LoadChunkData() can now be called again to resize the buffer
470          after a Chunk::Resize() and before the File::Save() call to allow
471          placing the new data in the chunk's write buffer and perform the
472          resize and write operations in one rush
473    
474      * src/gigdump.cpp:
475        - fixed to show the correct amount of dimension regions instead of 32
476          (patch by James Wylder)
477    
478      * src/dlsdump.cpp:
479        - show for every region the name of the referenced sample
480        - show file name in quotation marks
481    
482    Version 2.0.2 (15 Aug 2005)
483    
484      * packaging changes:
485        - require automake (>= 1.5) for 'make -f Makefile.cvs'
486          (mandatory for 'dist-bzip2' automake option)
487    
488      * src/gig.cpp, src/gig.h:
489        - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
490          the extension files are read automatically when the samples are
491          loaded
492        - fixed the 24 bit decompression, the result should now be exact
493          instead of an approximation
494        - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
495          function to DimensionRegion
496    
497      * src/DLS.cpp, src/DLS.h:
498        - the upper bits of the pool table indices are read (used as
499          extension file numbers for gig v3)
500    
501      * src/RIFF.cpp, src/RIFF.h:
502        - the file name is remembered in the RIFF::File object
503    
504    Version 2.0.1 (12 Jun 2005)
505    
506      * packaging changes:
507        - include debian/ directory on 'make dist'
508        - create a bzip2 tarball on 'make dist'
509    
510    * src/gigextract.cpp:    * src/gigextract.cpp:
511      - show also version of libsndfile or build version of libaudiofile when      - show also version of libsndfile or build version of libaudiofile when
512        using the -v switch        using the -v switch
513        - fixed mutual link dependency to libsndfile / libaudiofile
514    
515      * src/gig.cpp, src/gig.h:
516        - added DimensionRegion::GetVelocityRelease function
517
