# 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    
8      * src/gig.cpp, src/gig.h:
9        - fixed bug in Script::SetGroup: the script chunk wasn't moved
10        - fixed compilation error with clang 3.4
11        - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
12          as one single monolithic gig file. In case .gig file is >= 2GB expect a
13          large monolithic file, otherwise if .gig file is < 2 GB check for
14          "extension" files (.gx01, .gx02, ...) instead.
15        - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
16          if there were dimensions after the velocity dimension: it only created
17          valid velocity tables for cases of dimensions lower than the velocity
18          dimension.
19        - added new method Sample::VerifyWaveData() which allows to check whether
20          a sample had been damaged for some reason
21        - Fix: samples' CRC checksums were damaged on file structure changes.
22        - Fix: samples' CRC checksums were misordered when a Sample was deleted.
23        - Added new method Sample::GetWaveDataCRC32Checksum().
24        - Changed default value of EG2Release (filter release time) to 60s.
25        - Instruments' default pitch bend range is now +-2 semi tones.
26        - Fixed CRC checksums being wrong sometimes.
27        - Fix: method File::AddContentOf() did not clone script groups and scripts
28          of passed original file.
29    
30      * src/DLS.cpp, src/DLS.h:
31        - Sample: wave pool offsets are now 64 bits (to allow support for files
32          larger than 4 GB).
33          
34      * src/RIFF.cpp, src/RIFF.h:
35        - added support for RIFF files larger than 4 GB, by default the required
36          internal RIFF file offset size is automatically detected (that is RIFF
37          files < 4 GB automatically use 32 bit offsets while files >= 4 GB
38          automatically use 64 bit offsets), a particular offset size can be forced
39          with a new option added to the RIFF File constructor though
40        - when saving a modified, grown RIFF file, the temporary file size during
41          Save() operation will no longer be larger than the final grown file size
42    
43      * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
44        - improved output of non-ascii characters in usage messages
45        - fixed printf format strings
46    
47      * src/tools/korg2gig.cpp:
48        - fixed c++11 narrowing warnings
49        - fixed fine tuning which was not translated at all
50    
51      * src/tools/gigdump.cpp:
52        - additionally print VelocityUpperLimit and DimensionUpperLimits of all
53          dimension regions
54        - additionally print RIFF chunk file offset and RIFF chunk size of sample
55          data
56        - added and implemented new parameter "--verify" which allows to check
57          the raw wave form data integrity of all samples
58        - added and implemented new parameter "--rebuild-checksums" which allows
59          to recalculate the CRC32 checksum of all samples' raw wave data and
60          rebuilding the gig file's global checksum table (i.e. in case the
61          file's checksum table was damaged)
62        - print samples' CRC32 checksums
63    
64      * src/tools/gigextract.cpp:
65        - Fix: if sample name contains a path separator (slash or backslash) then
66          replace them by a minus sign to avoid file system issues.
67    
68      * src/tools/gig2stereo.cpp:
69        - Also merge mono sample pairs with non matching loop information if
70          argument --incompatible was given.
71    
72      * packaging changes:
73        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
74          auto detect whether it (sh/c)ould output its messages in color.
75    
76    Version 4.0.0 (14 Jul 2015)
77      * general changes:

80        - removed gcc 4.7 warnings
81        - modernized configure script
82        - removed usage of deprecated Automake variable INCLUDES
83        - added new command line tool "gigmerge"
84        - added "const" keyword to several methods
85        - added new command line tool "gig2mono"
86        - added man page for "sf2dump"
87        - added new command line tool "korgdump" (and a man page for it)
88        - added new command line tool "korg2gig" (and a man page for it)
89        - moved source files of command line tools to new subdir src/tools
90        - libgig.so and libakai.so files are now installed under
91          $(prefix)/lib/libgig/ by default.
92        - Header files are now installed under $(prefix)/include/libgig/ by default.
93        - Fixed various packaging issues regarding installation directories
94          (fixes #218).
95        - added new command line tool "gig2stereo" (and a man page for it)
96        - unit tests: fixed wrong return value when test suite app exits
97          (patch by Ryan Schmidt)

106      * KORG file format:
107        - initial support for sample based instruments in KORG's file format
108          (.KMP and .KSF files)
109    
110      * AKAI file format:
111        - Added Linux/POSIX ported version of libakai. Note that libakai is released
112          under LGPL terms while libgig is released under GPL terms. To handle this
113          license difference appropriately the AKAI support part is built as
114          separate DLL (.so file).
115        - Fixed Mac OSX support so that the Akai lib files and tools compile without
116          any exotic third party libraries.
117        - Fixed various compilation errors for Windows.
118        - POSIX fix: open() requires third (mode) argument if used with O_CREAT
119          (fixes #219).
120    
121      * src/gig.cpp:
122        - bugfix: VCF velocity dynamic range and VCF velocity curve
123          weren't saved correctly

132        - added new method File::AddContentOf() for merging .gig files
133        - GIG FORMAT EXTENSION: added additional MIDI controllers for leverage
134          controller types (only works with LinuxSampler & gigedit, will not
135          work with Gigasampler/GigaStudio)
136        - added new method File::GetGroup(String name) for getting group by name
137        - added new method Region::GetDimensionDefinition(dimension_t type)

150        - Bugfix: Adding a new region in between two existing regions caused the
151          new one being dropped after save operation and the gig file being tainted
152          (chunks at wrong location in the RIFF tree).
153        - Added new method Instrument::MoveTo() which allows to rearrange the order
154          of instruments within the same gig file.
155    
156      * src/DLS.cpp, src/DLS.h:
157        - added new method File::GetFileName()

161          later on without passing a file name
162        - added inline helper methods overlaps() for struct range_t
163        - Added support for custom progress notification while saving to DLS file.
164        - Bugfix: Adding a new region in between two existing regions caused the

178          later on without passing a file name
179        - added new method File::IsNew()
180        - added support for loading RIFF-like files with a bit different layout
181          than "real" RIFF files (used for KORG format support)
182        - added new method Chunk::GetFile()
183        - added new method Chunk::GetLayout()
184        - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one

192        - Cleanup of an old DLL binary backward compatibility hack.
193    
194      * src/gigextract.cpp:
195        - export sample loop, unity note and fine tune with libsndfile
196

214        - bugfix: EG3 depth parameter was not saved correctly
215        - fixed crash which occured when streaming a gig sample with
216          bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
217    
218      * src/RIFF.cpp, src/RIFF.h:
219        - bugfix: saving to the same file after the file size had been
220          increased made the file corrupt (#82)
221        - bugfix: refuse Chunk::Read() in case chunk has just been added, that
222          is not written physically yet (#82)
223        - bugfix: saving to the same file after the file size had been
224          decreased sometimes also made the file corrupt!
225        - bugfix: undefined behavior (e.g. endless loop) when opening zero
226          length files, now throws a RIFF::Exception instead (fixes bug #121)
227        - bugfix: destructor for base class RIFF::Chunk accessed members
228          of derived class RIFF::File, which is bad, and caused crashes
229          when using Visual C++
230        - bugfix: files that contain zero length RIFF lists were not read
231          correctly (fixes #127) (bug was introduced 2009-03-13)
232    
233    Version 3.2.1 (5 Dec 2007)
234    
235      * src/RIFF.cpp, src/RIFF.h:
236        - avoid Windows to perform unnecessary file stream caching which would
237          decrease disk streaming performance on Windows systems otherwise
238    
239      * src/gig.cpp, src/gig.h:
240        - added File::SetAutoLoad() and File::GetAutoLoad() for allowing

258        - added Resource::GenerateDLSID function
259        - write support fix: allow regions without mapped samples
260        - added method SetKeyRange() to the Region class which should be used

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

273          instrument constructors
274        - clear unused fields when saving samples and regions

278          dimension region chunks also placed wrong
279        - added initialization of some fixed info strings in file and
280          instrument
281        - write support: files created by libgig will now have the RIFF
282          chunks in correct order
283        - write support: two previously unknown fields in dimension
284          definition are now saved
285        - added constants for gig file versions
286        - write support: the 3crc and einf chunks are now created or
287          updated when a file is saved (3crc contains sample checksums,
288          einf contains file statistics)
289        - write support: DLSID is now generated on the file and the
290          instruments
291        - write support: improved the default values for dimension region
292          parameters
293        - more write support fixes: crossfade parameters were not saved,

295          when dimensions were added or deleted, v3 wave pool offsets were
296          not saved correctly
297        - write support: 24 bit samples can now be written
298        - write support: version 3 is now the default for new files

300          dimension regions without mapped samples are now allowed, 3gnl
301          list in v3 files now always has 128 entries, several parameters
302          where incorrectly saved due to an operator precedence mistake
303        - DeleteSample now removes all references to the deleted sample
304        - AddDimension now copies all parameters from existing dimension
305          regions and also makes sure that the samplechannel dimension is
306          placed first in the list of dimensions.
307        - added method GetParent() to class 'DimensionRegion', which returns its
308          parent Region
309        - fixed Instrument::UpdateRegionKeyTable() method which did not reset
310          unused areas
311        - added various setter methods to DimensionRegion class which take care
312          of updating lookup tables / caches.
313    
314      * src/RIFF.cpp, src/RIFF.h:
315        - added File::SetByteOrder method
316        - Windows fix: saving a new file didn't work
317    
318      * src/gigdump.cpp:

327    
328      * src/gig.cpp, src/gig.h:
329        - custom velocity splits now works for gig v3 files too
330        - added support for custom splits points for other dimensions than
331          velocity (gig v3 feature)
332        - added "smart midi" and "round robin keyboard" dimensions
333        - added new method File::DeleteGroupOnly() which only deletes the given
334          group but moves all its members to another group, the other method,
335          that is File::DeleteGroup() now removes not just the group, but also
336          all the samples that belong to that group
337        - fixed crash which occured on interfering File::DeleteSample() and
338          File::GetNextSample() calls (due to iterator invalidation)
339        - fixed group names which were not saved
340        - fixed group destructor which did not remove the RIFF chunk associated
341          with the group

343        - fixed constructor for Region, which did not initialize correctly
344          when used from Instrument::AddRegion
345        - when saving, override the gig::Regions sample reference simply by
346          the region's first dimension region's sample (avoids an exception
347          when trying to save a new instrument)
348        - fixed AddDimension() method which did not fill out all mandatory
349          dimension definition fields
350    
351      * src/DLS.cpp, src/DLS.h:
352        - added Instrument::MoveRegion method

354          causing an exception when trying to save a new instrument
355    
356      * src/RIFF.cpp, src/RIFF.h:
357        - fixed RIFF::Chunk destructor which did not unregister previously
358          resized chunks, leading to a "zero size chunk" exception when
359          File::Save() was called
360        - added List::MoveSubChunk method
361    
362    Version 3.1.0 (24 Nov 2006)

368      * src/gig.cpp, src/gig.h:
369        - added support for more than one set of custom velocity splits
370          inside a region (for example different velocity split levels for
371          pedal up and pedal down)
372        - sample loop parameters are now taken from the DimensionRegion
373          instead of the wave chunk
374        - keyswitching dimension is changed from split type "normal" to
375          "bit"
376        - real support for 24 bit samples - samples are not truncated to
377          16 bits anymore
378        - support for reading of ".art" files. (Merging of .art and .gig
379          files are not implemented yet.)

399    
400    Version 3.0.0 (28 Apr 2006)
401    
402      * general changes:
403        - added write support (that is for creating and modifying RIFF, DLS and
404          gig files)

406          files are now loaded even if mandatory RIFF chunks are missing
407        - fixed some memory management errors, one of them was causing a
408          crash when a multi-file gig was deallocated
409    
410      * src/gig.cpp, src/gig.h:
411        - fixed the GetVelocityCutoff function, it wasn't always using the
412          VCFVelocityScale parameter when no cutoff controller was defined
413        - support for the gig v3 feature to have a number of dimension
414          splits not equal to a power of two
415        - added write support (highly experimental)
416    
417      * src/DLS.cpp, src/DLS.h:
418        - fixed loading of Articulation Connections (<artl> list chunks were
419          seeked instead of ordinary <artl> data chunks)
420        - added write support (highly experimental)
421    
422      * src/RIFF.cpp, src/RIFF.h:
423        - added write support
424        - Chunk::LoadChunkData() can now be called again to resize the buffer
425          after a Chunk::Resize() and before the File::Save() call to allow
426          placing the new data in the chunk's write buffer and perform the
427          resize and write operations in one rush
428    
429      * src/gigdump.cpp:
430        - fixed to show the correct amount of dimension regions instead of 32
431          (patch by James Wylder)
432    
433      * src/dlsdump.cpp:
434        - show for every region the name of the referenced sample
435        - show file name in quotation marks
436    
437    Version 2.0.2 (15 Aug 2005)
438    
439      * packaging changes:
440        - require automake (>= 1.5) for 'make -f Makefile.cvs'
441          (mandatory for 'dist-bzip2' automake option)
442    
443      * src/gig.cpp, src/gig.h:
444        - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
445          the extension files are read automatically when the samples are
446          loaded
447        - fixed the 24 bit decompression, the result should now be exact
448          instead of an approximation
449        - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
450          function to DimensionRegion
451    
452      * src/DLS.cpp, src/DLS.h:
453        - the upper bits of the pool table indices are read (used as
454          extension file numbers for gig v3)
455    
456      * src/RIFF.cpp, src/RIFF.h:
457        - the file name is remembered in the RIFF::File object
458    
459    Version 2.0.1 (12 Jun 2005)
460    
461      * packaging changes:
462        - include debian/ directory on 'make dist'
463        - create a bzip2 tarball on 'make dist'
464    
465      * src/gigextract.cpp:
466        - show also version of libsndfile or build version of libaudiofile when
467          using the -v switch
468        - fixed mutual link dependency to libsndfile / libaudiofile
469    
470      * src/gig.cpp, src/gig.h:

472    
473    Version 2.0.0 (9 May 2005)
474    
475      * packaging changes:
476        - fixed conditional linkage of either libsndfile or libaudiofile
477          (if none of the two exist, configure script will abort)
478        - man pages are now auto generated with the correct libgig version
479    
480    * src/gig.cpp, src/gig.h:    * src/gig.cpp, src/gig.h:
