# 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    
11      * src/gig.cpp, src/gig.h:
12        - fixed bug in Script::SetGroup: the script chunk wasn't moved
13        - fixed compilation error with clang 3.4
14        - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
15          as one single monolithic gig file. In case .gig file is >= 2GB expect a
16          large monolithic file, otherwise if .gig file is < 2 GB check for
17          "extension" files (.gx01, .gx02, ...) instead.
18        - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
19          if there were dimensions after the velocity dimension: it only created
20          valid velocity tables for cases of dimensions lower than the velocity
21          dimension.
22        - added new method Sample::VerifyWaveData() which allows to check whether
23          a sample had been damaged for some reason
24        - Fix: samples' CRC checksums were damaged on file structure changes.
25        - Fix: samples' CRC checksums were misordered when a Sample was deleted.
26        - Added new method Sample::GetWaveDataCRC32Checksum().
27        - Changed default value of EG2Release (filter release time) to 60s.
28        - Instruments' default pitch bend range is now +-2 semi tones.
29        - Fixed CRC checksums being wrong sometimes.
30        - Fix: method File::AddContentOf() did not clone script groups and scripts
31          of passed original file.
32        - Added support for serializing & deserializing DimensionRegion
33          objects (and crossfade_t and leverage_ctrl_t objects).
34    
35      * src/DLS.cpp, src/DLS.h:
36        - Sample: wave pool offsets are now 64 bits (to allow support for files
37          larger than 4 GB).
38          
39      * src/RIFF.cpp, src/RIFF.h:
40        - added support for RIFF files larger than 4 GB, by default the required
41          internal RIFF file offset size is automatically detected (that is RIFF
42          files < 4 GB automatically use 32 bit offsets while files >= 4 GB
43          automatically use 64 bit offsets), a particular offset size can be forced
44          with a new option added to the RIFF File constructor though
45        - when saving a modified, grown RIFF file, the temporary file size during
46          Save() operation will no longer be larger than the final grown file size
47    
48      * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
49        - improved output of non-ascii characters in usage messages
50        - fixed printf format strings
51    
52      * src/tools/korg2gig.cpp:
53        - fixed c++11 narrowing warnings
54        - fixed fine tuning which was not translated at all
55    
56      * src/tools/gigdump.cpp:
57        - additionally print VelocityUpperLimit and DimensionUpperLimits of all
58          dimension regions
59        - additionally print RIFF chunk file offset and RIFF chunk size of sample
60          data
61        - added and implemented new parameter "--verify" which allows to check
62          the raw wave form data integrity of all samples
63        - added and implemented new parameter "--rebuild-checksums" which allows
64          to recalculate the CRC32 checksum of all samples' raw wave data and
65          rebuilding the gig file's global checksum table (i.e. in case the
66          file's checksum table was damaged)
67        - print samples' CRC32 checksums
68    
69      * src/tools/gigextract.cpp:
70        - Fix: if sample name contains a path separator (slash or backslash) then
71          replace them by a minus sign to avoid file system issues.
72    
73      * src/tools/gig2stereo.cpp:
74        - Also merge mono sample pairs with non matching loop information if
75          argument --incompatible was given.
76    
77      * packaging changes:
78        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
79          auto detect whether it (sh/c)ould output its messages in color.
80    
81    Version 4.0.0 (14 Jul 2015)
82      * general changes:

85        - removed gcc 4.7 warnings
86        - modernized configure script
87        - removed usage of deprecated Automake variable INCLUDES
88        - added new command line tool "gigmerge"
89        - added "const" keyword to several methods
90        - added new command line tool "gig2mono"
91        - added man page for "sf2dump"
92        - added new command line tool "korgdump" (and a man page for it)
93        - added new command line tool "korg2gig" (and a man page for it)
94        - moved source files of command line tools to new subdir src/tools
95        - libgig.so and libakai.so files are now installed under
96          $(prefix)/lib/libgig/ by default.
97        - Header files are now installed under $(prefix)/include/libgig/ by default.
98        - Fixed various packaging issues regarding installation directories
99          (fixes #218).
100        - added new command line tool "gig2stereo" (and a man page for it)

111      * KORG file format:
112        - initial support for sample based instruments in KORG's file format
113          (.KMP and .KSF files)
114    
115      * AKAI file format:
116        - Added Linux/POSIX ported version of libakai. Note that libakai is released
117          under LGPL terms while libgig is released under GPL terms. To handle this
118          license difference appropriately the AKAI support part is built as
119          separate DLL (.so file).
120        - Fixed Mac OSX support so that the Akai lib files and tools compile without
121          any exotic third party libraries.
122        - Fixed various compilation errors for Windows.
123        - POSIX fix: open() requires third (mode) argument if used with O_CREAT
124          (fixes #219).
125    
126      * src/gig.cpp:
127        - bugfix: VCF velocity dynamic range and VCF velocity curve
128          weren't saved correctly

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

151        - added new method Region::GetDimensionRegionIndexByValue()
152        - added new method Script::GetGroup()
153        - added new method Region::SetDimensionType()
154        - Added support for custom progress notification while saving to gig file.
155        - Bugfix: Adding a new region in between two existing regions caused the
156          new one being dropped after save operation and the gig file being tainted
157          (chunks at wrong location in the RIFF tree).
158        - Added new method Instrument::MoveTo() which allows to rearrange the order
159          of instruments within the same gig file.
160    
161      * src/DLS.cpp, src/DLS.h:
162        - added new method File::GetFileName()

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

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

191          one allows to move the subchunk from the current list to another list
192        - POSIX: only assume -1 result value as error on open() calls
193        - POSIX: show operating system's error reason if opening a file failed
194        - Added support for custom progress notification while saving to RIFF file.
195        - Fixed embarrassing old bug: POSIX read() errors were never detected on
196          Chunk::Read() calls due to signment incompatible variable.
197        - Cleanup of an old DLL binary backward compatibility hack.
198    
199      * src/gigextract.cpp:
200        - export sample loop, unity note and fine tune with libsndfile
201

215          Triggered rule is supported so far
216        - bugfix: removed another iterator invalidation in DeleteSample
217        - bugfix in Sample::LoadSampleData*(): reset sample read position to
218          sample start before trying to (re)load sample data from file (#82)
219        - bugfix: EG3 depth parameter was not saved correctly
220        - fixed crash which occured when streaming a gig sample with
221          bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
222    
223      * src/RIFF.cpp, src/RIFF.h:
224        - bugfix: saving to the same file after the file size had been
225          increased made the file corrupt (#82)
226        - bugfix: refuse Chunk::Read() in case chunk has just been added, that
227          is not written physically yet (#82)
228        - bugfix: saving to the same file after the file size had been
229          decreased sometimes also made the file corrupt!
230        - bugfix: undefined behavior (e.g. endless loop) when opening zero
231          length files, now throws a RIFF::Exception instead (fixes bug #121)
232        - bugfix: destructor for base class RIFF::Chunk accessed members
233          of derived class RIFF::File, which is bad, and caused crashes
234          when using Visual C++
235        - bugfix: files that contain zero length RIFF lists were not read
236          correctly (fixes #127) (bug was introduced 2009-03-13)
237    
238    Version 3.2.1 (5 Dec 2007)
239    
240      * src/RIFF.cpp, src/RIFF.h:
241        - avoid Windows to perform unnecessary file stream caching which would
242          decrease disk streaming performance on Windows systems otherwise
243    
244      * src/gig.cpp, src/gig.h:
245        - added File::SetAutoLoad() and File::GetAutoLoad() for allowing

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

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

278          instrument constructors
279        - clear unused fields when saving samples and regions
280        - fixed write support bugs: v3 dimension limits and chunksize
281          weren't saved, leverage controller of type controlchange
282          couldn't be saved, group name list chunk was placed wrong,
283          dimension region chunks also placed wrong
284        - added initialization of some fixed info strings in file and
285          instrument
286        - write support: files created by libgig will now have the RIFF

288        - write support: two previously unknown fields in dimension
289          definition are now saved
290        - added constants for gig file versions
291        - write support: the 3crc and einf chunks are now created or
292          updated when a file is saved (3crc contains sample checksums,
293          einf contains file statistics)
294        - write support: DLSID is now generated on the file and the
295          instruments
296        - write support: improved the default values for dimension region
297          parameters
298        - more write support fixes: crossfade parameters were not saved,

300          when dimensions were added or deleted, v3 wave pool offsets were
301          not saved correctly
302        - write support: 24 bit samples can now be written
303        - write support: version 3 is now the default for new files
304        - more write support fixes: the 3ewg chunk is now bigger for v3,
305          dimension regions without mapped samples are now allowed, 3gnl
306          list in v3 files now always has 128 entries, several parameters
307          where incorrectly saved due to an operator precedence mistake
308        - DeleteSample now removes all references to the deleted sample
309        - AddDimension now copies all parameters from existing dimension
310          regions and also makes sure that the samplechannel dimension is
311          placed first in the list of dimensions.
312        - added method GetParent() to class 'DimensionRegion', which returns its
313          parent Region
314        - fixed Instrument::UpdateRegionKeyTable() method which did not reset
315          unused areas
316        - added various setter methods to DimensionRegion class which take care
317          of updating lookup tables / caches.
318    
319      * src/RIFF.cpp, src/RIFF.h:
320        - added File::SetByteOrder method
321        - Windows fix: saving a new file didn't work
322    
323      * src/gigdump.cpp:

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

348        - fixed constructor for Region, which did not initialize correctly
349          when used from Instrument::AddRegion
350        - when saving, override the gig::Regions sample reference simply by
351          the region's first dimension region's sample (avoids an exception
352          when trying to save a new instrument)
353        - fixed AddDimension() method which did not fill out all mandatory
354          dimension definition fields
355    
356      * src/DLS.cpp, src/DLS.h:
357        - added Instrument::MoveRegion method
358        - fixed software info field which was wrongly stored on instruments,
359          causing an exception when trying to save a new instrument
360    
361      * src/RIFF.cpp, src/RIFF.h:
362        - fixed RIFF::Chunk destructor which did not unregister previously
363          resized chunks, leading to a "zero size chunk" exception when
364          File::Save() was called
365        - added List::MoveSubChunk method
366    
367    Version 3.1.0 (24 Nov 2006)

373      * src/gig.cpp, src/gig.h:
374        - added support for more than one set of custom velocity splits
375          inside a region (for example different velocity split levels for
376          pedal up and pedal down)
377        - sample loop parameters are now taken from the DimensionRegion
378          instead of the wave chunk
379        - keyswitching dimension is changed from split type "normal" to
380          "bit"
381        - real support for 24 bit samples - samples are not truncated to
382          16 bits anymore
383        - support for reading of ".art" files. (Merging of .art and .gig
384          files are not implemented yet.)

403          of Gigasampler write support)
404    
405    Version 3.0.0 (28 Apr 2006)
406    
407      * general changes:
408        - added write support (that is for creating and modifying RIFF, DLS and
409          gig files)
410        - loading DLS and gig files is now much more permissive, DLS and gig
411          files are now loaded even if mandatory RIFF chunks are missing
412        - fixed some memory management errors, one of them was causing a
413          crash when a multi-file gig was deallocated
414    
415      * src/gig.cpp, src/gig.h:
416        - fixed the GetVelocityCutoff function, it wasn't always using the
417          VCFVelocityScale parameter when no cutoff controller was defined
418        - support for the gig v3 feature to have a number of dimension
419          splits not equal to a power of two

421    
422      * src/DLS.cpp, src/DLS.h:
423        - fixed loading of Articulation Connections (<artl> list chunks were
424          seeked instead of ordinary <artl> data chunks)

426    
427      * src/RIFF.cpp, src/RIFF.h:
428        - added write support
429        - Chunk::LoadChunkData() can now be called again to resize the buffer
430          after a Chunk::Resize() and before the File::Save() call to allow
431          placing the new data in the chunk's write buffer and perform the
432          resize and write operations in one rush
433    
434      * src/gigdump.cpp:
435        - fixed to show the correct amount of dimension regions instead of 32
436          (patch by James Wylder)
437    
438      * src/dlsdump.cpp:
439        - show for every region the name of the referenced sample
440        - show file name in quotation marks
441    
442    Version 2.0.2 (15 Aug 2005)
443    
444      * packaging changes:
445        - require automake (>= 1.5) for 'make -f Makefile.cvs'

449        - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
450          the extension files are read automatically when the samples are
451          loaded
452        - fixed the 24 bit decompression, the result should now be exact
453          instead of an approximation
454        - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
455          function to DimensionRegion
456    
457      * src/DLS.cpp, src/DLS.h:
458        - the upper bits of the pool table indices are read (used as
459          extension file numbers for gig v3)
460    
461      * src/RIFF.cpp, src/RIFF.h:
462        - the file name is remembered in the RIFF::File object
463
