# Line 1  Line 1 
1    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/Serialization.cpp, src/Serialization.h:
49        - Archive: Added method isModified().
50        - Archive: Added method setAutoValue().
51        - Archive: Added method setIntValue().
52        - Archive: Added method setRealValue().
53        - Archive: Added method setBoolValue().
54        - Archive: Added method setEnumValue().
55        - Archive: Added method valueAsString().
56        - Archive::rawData(): Automatically re-encode new raw data stream if
57          archive had been modified (i.e. by remove(), setAutoValue(), etc.).
58        - Object: Added method memberByUID().
59        - Object: remove() method is now protected.
60        - Archive: Added method removeMember();
61    
62      * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
63        - improved output of non-ascii characters in usage messages
64        - fixed printf format strings
65    
66      * src/tools/korg2gig.cpp:
67        - fixed c++11 narrowing warnings
68        - fixed fine tuning which was not translated at all
69    
70      * src/tools/gigdump.cpp:
71        - additionally print VelocityUpperLimit and DimensionUpperLimits of all
72          dimension regions
73        - additionally print RIFF chunk file offset and RIFF chunk size of sample
74          data
75        - added and implemented new parameter "--verify" which allows to check
76          the raw wave form data integrity of all samples
77        - added and implemented new parameter "--rebuild-checksums" which allows
78          to recalculate the CRC32 checksum of all samples' raw wave data and
79          rebuilding the gig file's global checksum table (i.e. in case the
80          file's checksum table was damaged)
81        - print samples' CRC32 checksums
82    
83      * src/tools/gigextract.cpp:
84        - Fix: if sample name contains a path separator (slash or backslash) then
85          replace them by a minus sign to avoid file system issues.
86    
87      * src/tools/gig2stereo.cpp:
88        - Also merge mono sample pairs with non matching loop information if
89          argument --incompatible was given.
90    
91      * packaging changes:
92        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
93          auto detect whether it (sh/c)ould output its messages in color.
94    
95    Version 4.0.0 (14 Jul 2015)
96      * general changes:

109        - libgig.so and libakai.so files are now installed under
110          $(prefix)/lib/libgig/ by default.
111        - Header files are now installed under $(prefix)/include/libgig/ by default.
112        - Fixed various packaging issues regarding installation directories
113          (fixes #218).
114        - added new command line tool "gig2stereo" (and a man page for it)
115        - unit tests: fixed wrong return value when test suite app exits
116          (patch by Ryan Schmidt)
117        - added new command line tool "sf2extract" (and a man page for it)
118    
119      * SoundFont file format:

128    
129      * AKAI file format:
130        - Added Linux/POSIX ported version of libakai. Note that libakai is released
131          under LGPL terms while libgig is released under GPL terms. To handle this
132          license difference appropriately the AKAI support part is built as
133          separate DLL (.so file).

135          any exotic third party libraries.
136        - Fixed various compilation errors for Windows.
137        - POSIX fix: open() requires third (mode) argument if used with O_CREAT
138          (fixes #219).
139    
140      * src/gig.cpp:
141        - bugfix: VCF velocity dynamic range and VCF velocity curve
142          weren't saved correctly
143        - implemented File::AddDuplicateInstrument()
144        - bugfix: negative EG3 depth values were not correctly parsed or

146        - added write support for CtrlTrigger midi rule
147        - added read and write support for Legato and Alternator midi
148          rules
149        - bugfix: sample groups were sometimes created multiple times or with
150          wrong textual group name
151        - added new method File::AddContentOf() for merging .gig files
152        - GIG FORMAT EXTENSION: added additional MIDI controllers for leverage
153          controller types (only works with LinuxSampler & gigedit, will not
154          work with Gigasampler/GigaStudio)
155        - added new method File::GetGroup(String name) for getting group by name
156        - added new method Region::GetDimensionDefinition(dimension_t type)

165        - added new method Region::GetDimensionRegionIndexByValue()
166        - added new method Script::GetGroup()
167        - added new method Region::SetDimensionType()
168        - Added support for custom progress notification while saving to gig file.
169        - Bugfix: Adding a new region in between two existing regions caused the
170          new one being dropped after save operation and the gig file being tainted
171          (chunks at wrong location in the RIFF tree).
172        - Added new method Instrument::MoveTo() which allows to rearrange the order
173          of instruments within the same gig file.
174    
175      * src/DLS.cpp, src/DLS.h:

197          later on without passing a file name
198        - added new method File::IsNew()
199        - added support for loading RIFF-like files with a bit different layout
200          than "real" RIFF files (used for KORG format support)
201        - added new method Chunk::GetFile()
202        - added new method Chunk::GetLayout()
203        - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one

207        - POSIX: show operating system's error reason if opening a file failed
208        - Added support for custom progress notification while saving to RIFF file.
209        - Fixed embarrassing old bug: POSIX read() errors were never detected on

211        - Cleanup of an old DLL binary backward compatibility hack.
212    
213      * src/gigextract.cpp:
214        - export sample loop, unity note and fine tune with libsndfile
215

229          Triggered rule is supported so far
230        - bugfix: removed another iterator invalidation in DeleteSample
231        - bugfix in Sample::LoadSampleData*(): reset sample read position to
232          sample start before trying to (re)load sample data from file (#82)
233        - bugfix: EG3 depth parameter was not saved correctly
234        - fixed crash which occured when streaming a gig sample with
235          bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
236    
237      * src/RIFF.cpp, src/RIFF.h:
238        - bugfix: saving to the same file after the file size had been
239          increased made the file corrupt (#82)
240        - bugfix: refuse Chunk::Read() in case chunk has just been added, that
241          is not written physically yet (#82)
242        - bugfix: saving to the same file after the file size had been
243          decreased sometimes also made the file corrupt!
244        - bugfix: undefined behavior (e.g. endless loop) when opening zero
245          length files, now throws a RIFF::Exception instead (fixes bug #121)
246        - bugfix: destructor for base class RIFF::Chunk accessed members
247          of derived class RIFF::File, which is bad, and caused crashes
248          when using Visual C++
249        - bugfix: files that contain zero length RIFF lists were not read
250          correctly (fixes #127) (bug was introduced 2009-03-13)
251    
252    Version 3.2.1 (5 Dec 2007)
253    
254      * src/RIFF.cpp, src/RIFF.h:
255        - avoid Windows to perform unnecessary file stream caching which would
256          decrease disk streaming performance on Windows systems otherwise
257    
258      * src/gig.cpp, src/gig.h:
259        - added File::SetAutoLoad() and File::GetAutoLoad() for allowing
260          applications to retrieve very superficial informations like amount of
261          instruments and their names in a very fast way
262    
263    Version 3.2.0 (14 Oct 2007)

281        - MoveRegion() method of Region class is now private
282        - added SetGain() method to Sampler class
283        - fixed crash when saving a file after a sample loop was added
284

286        - fixed segmentation fault in the gig::File destructor sequence which
287          happened when gig::Group informations were accessed before
288        - fixed write support for big-endian systems
289        - defined lengths of a fixed set of info strings. These strings
290          are saved when the file is written, even if they are empty.

303          definition are now saved
304        - added constants for gig file versions
305        - write support: the 3crc and einf chunks are now created or
306          updated when a file is saved (3crc contains sample checksums,
307          einf contains file statistics)
308        - write support: DLSID is now generated on the file and the
309          instruments
310        - write support: improved the default values for dimension region
311          parameters
312        - more write support fixes: crossfade parameters were not saved,

314          when dimensions were added or deleted, v3 wave pool offsets were
315          not saved correctly
316        - write support: 24 bit samples can now be written
317        - write support: version 3 is now the default for new files
318        - more write support fixes: the 3ewg chunk is now bigger for v3,
319          dimension regions without mapped samples are now allowed, 3gnl
320          list in v3 files now always has 128 entries, several parameters
321          where incorrectly saved due to an operator precedence mistake
322        - DeleteSample now removes all references to the deleted sample
323        - AddDimension now copies all parameters from existing dimension
324          regions and also makes sure that the samplechannel dimension is
325          placed first in the list of dimensions.
326        - added method GetParent() to class 'DimensionRegion', which returns its
327          parent Region
328        - fixed Instrument::UpdateRegionKeyTable() method which did not reset
329          unused areas
330        - added various setter methods to DimensionRegion class which take care
331          of updating lookup tables / caches.
332    
333      * src/RIFF.cpp, src/RIFF.h:
334        - added File::SetByteOrder method
335        - Windows fix: saving a new file didn't work
336    
337      * src/gigdump.cpp:

340    Version 3.1.1 (24 Mar 2007)
341    
342      * packaging changes:
343        - ported to Windows using native Windows functions for file IO
344          (provided Dev-C++ + mingw project file)
345        - only export relevant files to Doxygen API documentation
346    
347      * src/gig.cpp, src/gig.h:
348        - custom velocity splits now works for gig v3 files too
349        - added support for custom splits points for other dimensions than
350          velocity (gig v3 feature)
351        - added "smart midi" and "round robin keyboard" dimensions
352        - added new method File::DeleteGroupOnly() which only deletes the given
353          group but moves all its members to another group, the other method,
354          that is File::DeleteGroup() now removes not just the group, but also
355          all the samples that belong to that group
356        - fixed crash which occured on interfering File::DeleteSample() and
357          File::GetNextSample() calls (due to iterator invalidation)
358        - fixed group names which were not saved
359        - fixed group destructor which did not remove the RIFF chunk associated
360          with the group

362        - fixed constructor for Region, which did not initialize correctly
363          when used from Instrument::AddRegion
364        - when saving, override the gig::Regions sample reference simply by
365          the region's first dimension region's sample (avoids an exception
366          when trying to save a new instrument)
367        - fixed AddDimension() method which did not fill out all mandatory
368          dimension definition fields
369    
370      * src/DLS.cpp, src/DLS.h:
371        - added Instrument::MoveRegion method

373          causing an exception when trying to save a new instrument
374    
375      * src/RIFF.cpp, src/RIFF.h:
376        - fixed RIFF::Chunk destructor which did not unregister previously
377          resized chunks, leading to a "zero size chunk" exception when
378          File::Save() was called
379        - added List::MoveSubChunk method
380    
381    Version 3.1.0 (24 Nov 2006)

387      * src/gig.cpp, src/gig.h:
388        - added support for more than one set of custom velocity splits
389          inside a region (for example different velocity split levels for
390          pedal up and pedal down)
391        - sample loop parameters are now taken from the DimensionRegion
392          instead of the wave chunk
393        - keyswitching dimension is changed from split type "normal" to
394          "bit"
395        - real support for 24 bit samples - samples are not truncated to
396          16 bits anymore
397        - support for reading of ".art" files. (Merging of .art and .gig
398          files are not implemented yet.)
399        - several fixes for the write support
400        - support for sample groups added
401    
402      * src/DLS.cpp, src/DLS.h:

404        - removed incorrect use of memccpy in the write support (patch by
405          Jeremy Kerr)
406        - several fixes for the write support
407    
408      * src/gigextract.cpp:
409        - real support for 24 bit samples
410    
411      * src/gigdump.cpp:
412        - print global file informations
413        - print sample groups
414    
415      * general changes:
416        - added CPPUnit test cases (at the moment primarily for automatic check
417          of Gigasampler write support)
418    
419    Version 3.0.0 (28 Apr 2006)
420    
421      * general changes:
422        - added write support (that is for creating and modifying RIFF, DLS and
423          gig files)
424        - loading DLS and gig files is now much more permissive, DLS and gig
425          files are now loaded even if mandatory RIFF chunks are missing
426        - fixed some memory management errors, one of them was causing a
427          crash when a multi-file gig was deallocated
428    
429      * src/gig.cpp, src/gig.h:
430        - fixed the GetVelocityCutoff function, it wasn't always using the
431          VCFVelocityScale parameter when no cutoff controller was defined
432        - support for the gig v3 feature to have a number of dimension
433          splits not equal to a power of two
434        - added write support (highly experimental)
435    
436      * src/DLS.cpp, src/DLS.h:
437        - fixed loading of Articulation Connections (<artl> list chunks were
438          seeked instead of ordinary <artl> data chunks)
439        - added write support (highly experimental)
440    
441      * src/RIFF.cpp, src/RIFF.h:
442        - added write support
443        - Chunk::LoadChunkData() can now be called again to resize the buffer
444          after a Chunk::Resize() and before the File::Save() call to allow
445          placing the new data in the chunk's write buffer and perform the
446          resize and write operations in one rush
447    
448      * src/gigdump.cpp:
449        - fixed to show the correct amount of dimension regions instead of 32
450          (patch by James Wylder)
451    
452      * src/dlsdump.cpp:
453        - show for every region the name of the referenced sample
454        - show file name in quotation marks
455    
456    Version 2.0.2 (15 Aug 2005)
457    
458      * packaging changes:
459        - require automake (>= 1.5) for 'make -f Makefile.cvs'
460          (mandatory for 'dist-bzip2' automake option)
461    
462      * src/gig.cpp, src/gig.h:
463        - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
464          the extension files are read automatically when the samples are
465          loaded
466        - fixed the 24 bit decompression, the result should now be exact
467          instead of an approximation
468        - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
469          function to DimensionRegion
470    
471      * src/DLS.cpp, src/DLS.h:
472        - the upper bits of the pool table indices are read (used as
473          extension file numbers for gig v3)
474    
475      * src/RIFF.cpp, src/RIFF.h:
476        - the file name is remembered in the RIFF::File object
477    
478  Version 2.0.1 (12 Jun 2005)  Version 2.0.1 (12 Jun 2005)
479    
480      * packaging changes:
481        - include debian/ directory on 'make dist'
482        - create a bzip2 tarball on 'make dist'
483    
484    * src/gigextract.cpp:    * src/gigextract.cpp:
485      - show also version of libsndfile or build version of libaudiofile when      - show also version of libsndfile or build version of libaudiofile when
486        using the -v switch        using the -v switch
