# 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/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        - Archive: Added methods name() and setName().
62        - Archive: Added methods comment() and setComment().
63        - Archive: Added methods timeStampCreated(), timeStampModified(),
64          dateTimeCreated() and dateTimeModified().
65    
66      * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
67        - improved output of non-ascii characters in usage messages
68        - fixed printf format strings
69    
70      * src/tools/korg2gig.cpp:
71        - fixed c++11 narrowing warnings
72        - fixed fine tuning which was not translated at all
73    
74      * src/tools/gigdump.cpp:
75        - additionally print VelocityUpperLimit and DimensionUpperLimits of all
76          dimension regions
77        - additionally print RIFF chunk file offset and RIFF chunk size of sample
78          data
79        - added and implemented new parameter "--verify" which allows to check
80          the raw wave form data integrity of all samples
81        - added and implemented new parameter "--rebuild-checksums" which allows
82          to recalculate the CRC32 checksum of all samples' raw wave data and
83          rebuilding the gig file's global checksum table (i.e. in case the
84          file's checksum table was damaged)
85        - print samples' CRC32 checksums
86    
87      * src/tools/gigextract.cpp:
88        - Fix: if sample name contains a path separator (slash or backslash) then
89          replace them by a minus sign to avoid file system issues.
90    
91      * src/tools/gig2stereo.cpp:
92        - Also merge mono sample pairs with non matching loop information if
93          argument --incompatible was given.
94    
95      * packaging changes:
96        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
97          auto detect whether it (sh/c)ould output its messages in color.
98    
99    Version 4.0.0 (14 Jul 2015)

112        - moved source files of command line tools to new subdir src/tools
113        - libgig.so and libakai.so files are now installed under
114          $(prefix)/lib/libgig/ by default.
115        - Header files are now installed under $(prefix)/include/libgig/ by default.
116        - Fixed various packaging issues regarding installation directories
117          (fixes #218).
118        - added new command line tool "gig2stereo" (and a man page for it)

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

139          any exotic third party libraries.
140        - Fixed various compilation errors for Windows.
141        - POSIX fix: open() requires third (mode) argument if used with O_CREAT
142          (fixes #219).
143    
144      * src/gig.cpp:
145        - bugfix: VCF velocity dynamic range and VCF velocity curve
146          weren't saved correctly

151        - added read and write support for Legato and Alternator midi
152          rules
153        - bugfix: sample groups were sometimes created multiple times or with
154          wrong textual group name
155        - added new method File::AddContentOf() for merging .gig files
156        - GIG FORMAT EXTENSION: added additional MIDI controllers for leverage
157          controller types (only works with LinuxSampler & gigedit, will not

173        - Bugfix: Adding a new region in between two existing regions caused the
174          new one being dropped after save operation and the gig file being tainted
175          (chunks at wrong location in the RIFF tree).
176        - Added new method Instrument::MoveTo() which allows to rearrange the order
177          of instruments within the same gig file.
178    
179      * src/DLS.cpp, src/DLS.h:

202        - added new method File::IsNew()
203        - added support for loading RIFF-like files with a bit different layout
204          than "real" RIFF files (used for KORG format support)
205        - added new method Chunk::GetFile()
206        - added new method Chunk::GetLayout()
207        - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one

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

215        - Cleanup of an old DLL binary backward compatibility hack.
216    
217      * src/gigextract.cpp:
218        - export sample loop, unity note and fine tune with libsndfile
219

233          Triggered rule is supported so far
234        - bugfix: removed another iterator invalidation in DeleteSample
235        - bugfix in Sample::LoadSampleData*(): reset sample read position to
236          sample start before trying to (re)load sample data from file (#82)
237        - bugfix: EG3 depth parameter was not saved correctly
238        - fixed crash which occured when streaming a gig sample with
239          bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
240    
241      * src/RIFF.cpp, src/RIFF.h:

243          increased made the file corrupt (#82)
244        - bugfix: refuse Chunk::Read() in case chunk has just been added, that
245          is not written physically yet (#82)
246        - bugfix: saving to the same file after the file size had been
247          decreased sometimes also made the file corrupt!
248        - bugfix: undefined behavior (e.g. endless loop) when opening zero
249          length files, now throws a RIFF::Exception instead (fixes bug #121)
250        - bugfix: destructor for base class RIFF::Chunk accessed members
251          of derived class RIFF::File, which is bad, and caused crashes
252          when using Visual C++
253        - bugfix: files that contain zero length RIFF lists were not read
254          correctly (fixes #127) (bug was introduced 2009-03-13)
255    
256    Version 3.2.1 (5 Dec 2007)
257    
258      * src/RIFF.cpp, src/RIFF.h:
259        - avoid Windows to perform unnecessary file stream caching which would
260          decrease disk streaming performance on Windows systems otherwise
261    
262      * src/gig.cpp, src/gig.h:
263        - added File::SetAutoLoad() and File::GetAutoLoad() for allowing

281        - added Resource::GenerateDLSID function
282        - write support fix: allow regions without mapped samples
283        - added method SetKeyRange() to the Region class which should be used
284          instead of setting the KeyRange member variable directly
285        - MoveRegion() method of Region class is now private
286        - added SetGain() method to Sampler class
287        - fixed crash when saving a file after a sample loop was added

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

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

318          when dimensions were added or deleted, v3 wave pool offsets were
319          not saved correctly
320        - write support: 24 bit samples can now be written
321        - write support: version 3 is now the default for new files
322        - more write support fixes: the 3ewg chunk is now bigger for v3,
323          dimension regions without mapped samples are now allowed, 3gnl

325          where incorrectly saved due to an operator precedence mistake
326        - DeleteSample now removes all references to the deleted sample
327        - AddDimension now copies all parameters from existing dimension
328          regions and also makes sure that the samplechannel dimension is
329          placed first in the list of dimensions.
330        - added method GetParent() to class 'DimensionRegion', which returns its
331          parent Region
332        - fixed Instrument::UpdateRegionKeyTable() method which did not reset
333          unused areas
334        - added various setter methods to DimensionRegion class which take care
335          of updating lookup tables / caches.
336    
337      * src/RIFF.cpp, src/RIFF.h:
338        - added File::SetByteOrder method
339        - Windows fix: saving a new file didn't work
340    
341      * src/gigdump.cpp:

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

366        - fixed constructor for Region, which did not initialize correctly
367          when used from Instrument::AddRegion
368        - when saving, override the gig::Regions sample reference simply by
369          the region's first dimension region's sample (avoids an exception
370          when trying to save a new instrument)
371        - fixed AddDimension() method which did not fill out all mandatory
372          dimension definition fields
373    
374      * src/DLS.cpp, src/DLS.h:
375        - added Instrument::MoveRegion method

377          causing an exception when trying to save a new instrument
378    
379      * src/RIFF.cpp, src/RIFF.h:
380        - fixed RIFF::Chunk destructor which did not unregister previously
381          resized chunks, leading to a "zero size chunk" exception when
382          File::Save() was called
383        - added List::MoveSubChunk method
384    
385    Version 3.1.0 (24 Nov 2006)

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

431          crash when a multi-file gig was deallocated
432    
433      * src/gig.cpp, src/gig.h:
434        - fixed the GetVelocityCutoff function, it wasn't always using the

444    
445      * src/RIFF.cpp, src/RIFF.h:
446        - added write support
447        - Chunk::LoadChunkData() can now be called again to resize the buffer
448          after a Chunk::Resize() and before the File::Save() call to allow
449          placing the new data in the chunk's write buffer and perform the
450          resize and write operations in one rush
451    
452      * src/gigdump.cpp:
453        - fixed to show the correct amount of dimension regions instead of 32
454          (patch by James Wylder)
455    
456      * src/dlsdump.cpp:
457        - show for every region the name of the referenced sample
458        - show file name in quotation marks
459

461    
462      * packaging changes:
463        - require automake (>= 1.5) for 'make -f Makefile.cvs'

467        - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
468          the extension files are read automatically when the samples are
469          loaded
470        - fixed the 24 bit decompression, the result should now be exact
471          instead of an approximation
472        - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
473          function to DimensionRegion
474    
475      * src/DLS.cpp, src/DLS.h:
476        - the upper bits of the pool table indices are read (used as
477          extension file numbers for gig v3)
478    
479      * src/RIFF.cpp, src/RIFF.h:
480        - the file name is remembered in the RIFF::File object
