# 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    
6      * src/gig.cpp, src/gig.h:
7        - fixed bug in Script::SetGroup: the script chunk wasn't moved
8        - fixed compilation error with clang 3.4
9        - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
10          as one single monolithic gig file. In case .gig file is >= 2GB expect a
11          large monolithic file, otherwise if .gig file is < 2 GB check for
12          "extension" files (.gx01, .gx02, ...) instead.
13        - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
14          if there were dimensions after the velocity dimension: it only created
15          valid velocity tables for cases of dimensions lower than the velocity
16          dimension.
17    
18      * src/DLS.cpp, src/DLS.h:
19        - Sample: wave pool offsets are now 64 bits (to allow support for files
20          larger than 4 GB).
21          
22      * src/RIFF.cpp, src/RIFF.h:
23        - added support for RIFF files larger than 4 GB, by default the required
24          internal RIFF file offset size is automatically detected (that is RIFF
25          files < 4 GB automatically use 32 bit offsets while files >= 4 GB
26          automatically use 64 bit offsets), a particular offset size can be forced
27          with a new option added to the RIFF File constructor though
28        - when saving a modified, grown RIFF file, the temporary file size during
29          Save() operation will no longer be larger than the final grown file size
30    
31      * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
32        - improved output of non-ascii characters in usage messages
33        - fixed printf format strings
34    
35      * src/tools/korg2gig.cpp:
36        - fixed c++11 narrowing warnings
37        - fixed fine tuning which was not translated at all
38    
39      * src/tools/gigdump.cpp:
40        - additionally print VelocityUpperLimit and DimensionUpperLimits of all
41          dimension regions
42    
43      * packaging changes:
44        - Automake: set environment variable GCC_COLORS=auto to allow GCC to
45          auto detect whether it (sh/c)ould output its messages in color.
46    
47    Version 4.0.0 (14 Jul 2015)
48      * general changes:
49        - minor Makefile fix for parallel make
50        - Mac OS X: link with CoreFoundation (for the UUID function)
51        - removed gcc 4.7 warnings
52        - modernized configure script
53        - removed usage of deprecated Automake variable INCLUDES
54        - added new command line tool "gigmerge"
55        - added "const" keyword to several methods
56        - added new command line tool "gig2mono"
57        - added man page for "sf2dump"
58        - added new command line tool "korgdump" (and a man page for it)
59        - added new command line tool "korg2gig" (and a man page for it)
60        - moved source files of command line tools to new subdir src/tools
61        - libgig.so and libakai.so files are now installed under
62          $(prefix)/lib/libgig/ by default.
63        - Header files are now installed under $(prefix)/include/libgig/ by default.
64        - Fixed various packaging issues regarding installation directories
65          (fixes #218).
66        - added new command line tool "gig2stereo" (and a man page for it)
67        - unit tests: fixed wrong return value when test suite app exits
68          (patch by Ryan Schmidt)
69        - added new command line tool "sf2extract" (and a man page for it)
70    
71      * SoundFont file format:
72        - initial implementation
73        - changed region lookup API to avoid malloc in RT threads
74        - fixed GetEG1Sustain which didn't return correct value
75        - bugfix: GetPan always returned -1, 0 or 1
76    
77      * KORG file format:
78        - initial support for sample based instruments in KORG's file format
79          (.KMP and .KSF files)
80    
81      * AKAI file format:
82        - Added Linux/POSIX ported version of libakai. Note that libakai is released
83          under LGPL terms while libgig is released under GPL terms. To handle this
84          license difference appropriately the AKAI support part is built as
85          separate DLL (.so file).
86        - Fixed Mac OSX support so that the Akai lib files and tools compile without
87          any exotic third party libraries.
88        - Fixed various compilation errors for Windows.
89        - POSIX fix: open() requires third (mode) argument if used with O_CREAT
90          (fixes #219).
91    
92      * src/gig.cpp:
93        - bugfix: VCF velocity dynamic range and VCF velocity curve
94          weren't saved correctly
95        - implemented File::AddDuplicateInstrument()
96        - bugfix: negative EG3 depth values were not correctly parsed or
97          saved
98        - added write support for CtrlTrigger midi rule
99        - added read and write support for Legato and Alternator midi
100          rules
101        - bugfix: sample groups were sometimes created multiple times or with
102          wrong textual group name
103        - added new method File::AddContentOf() for merging .gig files
104        - GIG FORMAT EXTENSION: added additional MIDI controllers for leverage
105          controller types (only works with LinuxSampler & gigedit, will not
106          work with Gigasampler/GigaStudio)
107        - added new method File::GetGroup(String name) for getting group by name
108        - added new method Region::GetDimensionDefinition(dimension_t type)
109        - bugfix: don't alter region pointer in DimensionRegion::CopyAssign()
110        - added some more sanity checks in Region::AddDimension()
111        - added new method Region::DeleteDimensionZone(dimension_t, int)
112        - added new method Region::SplitDimensionZone(dimension_t, int)
113        - Fixed crash caused by Region::GetDimensionRegionByValue() that happened
114          with certain velocity split sounds under certain conditions (added bound
115          constraints to prevent that)
116        - GIG FORMAT EXTENSION: added support for real-time instrument scripts.
117        - added new method Region::GetDimensionRegionIndexByValue()
118        - added new method Script::GetGroup()
119        - added new method Region::SetDimensionType()
120        - Added support for custom progress notification while saving to gig file.
121        - Bugfix: Adding a new region in between two existing regions caused the
122          new one being dropped after save operation and the gig file being tainted
123          (chunks at wrong location in the RIFF tree).
124        - Added new method Instrument::MoveTo() which allows to rearrange the order
125          of instruments within the same gig file.
126    
127      * src/DLS.cpp, src/DLS.h:
128        - added new method File::GetFileName()

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

137          (chunks at wrong location in the RIFF tree).
138    
139      * src/SF.cpp, src/SF.h:
140        - added new method Sample::ReadNoClear()
141    
142      * src/RIFF.cpp, src/RIFF.h:

146          fails
147        - added new method Chunk::ReadString
148        - added new method File::SetFileName() allowing to call File::Save()
149          later on without passing a file name
150        - added new method File::IsNew()
151        - added support for loading RIFF-like files with a bit different layout
152          than "real" RIFF files (used for KORG format support)
153        - added new method Chunk::GetFile()
154        - added new method Chunk::GetLayout()
155        - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one
156          allows to move a subchunk within the current List, whereas the new 2nd
157          one allows to move the subchunk from the current list to another list
158        - POSIX: only assume -1 result value as error on open() calls
159        - POSIX: show operating system's error reason if opening a file failed
160        - Added support for custom progress notification while saving to RIFF file.
161        - Fixed embarrassing old bug: POSIX read() errors were never detected on
162          Chunk::Read() calls due to signment incompatible variable.
163        - Cleanup of an old DLL binary backward compatibility hack.
164    
165      * src/gigextract.cpp:
166        - export sample loop, unity note and fine tune with libsndfile
167    
168      * src/riftree.cpp:
169        - added more command line options for being able to also dump other kind

186        - fixed crash which occured when streaming a gig sample with
187          bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
188    
189      * src/RIFF.cpp, src/RIFF.h:
190        - bugfix: saving to the same file after the file size had been
191          increased made the file corrupt (#82)
192        - bugfix: refuse Chunk::Read() in case chunk has just been added, that
193          is not written physically yet (#82)
194        - bugfix: saving to the same file after the file size had been
195          decreased sometimes also made the file corrupt!
196        - bugfix: undefined behavior (e.g. endless loop) when opening zero
197          length files, now throws a RIFF::Exception instead (fixes bug #121)
198        - bugfix: destructor for base class RIFF::Chunk accessed members
199          of derived class RIFF::File, which is bad, and caused crashes
200          when using Visual C++
201        - bugfix: files that contain zero length RIFF lists were not read
202          correctly (fixes #127) (bug was introduced 2009-03-13)
203    
204    Version 3.2.1 (5 Dec 2007)
205    
206      * src/RIFF.cpp, src/RIFF.h:
207        - avoid Windows to perform unnecessary file stream caching which would
208          decrease disk streaming performance on Windows systems otherwise
209    
210      * src/gig.cpp, src/gig.h:
211        - added File::SetAutoLoad() and File::GetAutoLoad() for allowing

230        - write support fix: allow regions without mapped samples
231        - added method SetKeyRange() to the Region class which should be used

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

244          instrument constructors
245        - clear unused fields when saving samples and regions

256        - added constants for gig file versions
257        - write support: the 3crc and einf chunks are now created or
258          updated when a file is saved (3crc contains sample checksums,
259          einf contains file statistics)
260        - write support: DLSID is now generated on the file and the
261          instruments
262        - write support: improved the default values for dimension region
263          parameters
264        - more write support fixes: crossfade parameters were not saved,

266          when dimensions were added or deleted, v3 wave pool offsets were
267          not saved correctly
268        - write support: 24 bit samples can now be written
269        - write support: version 3 is now the default for new files
270        - more write support fixes: the 3ewg chunk is now bigger for v3,
271          dimension regions without mapped samples are now allowed, 3gnl
272          list in v3 files now always has 128 entries, several parameters
273          where incorrectly saved due to an operator precedence mistake
274        - DeleteSample now removes all references to the deleted sample
275        - AddDimension now copies all parameters from existing dimension
276          regions and also makes sure that the samplechannel dimension is
277          placed first in the list of dimensions.
278        - added method GetParent() to class 'DimensionRegion', which returns its
279          parent Region
280        - fixed Instrument::UpdateRegionKeyTable() method which did not reset
281          unused areas
282        - added various setter methods to DimensionRegion class which take care
283          of updating lookup tables / caches.
284    
285      * src/RIFF.cpp, src/RIFF.h:
286        - added File::SetByteOrder method
287        - Windows fix: saving a new file didn't work
288    
289      * src/gigdump.cpp:

298    
299      * src/gig.cpp, src/gig.h:
300        - custom velocity splits now works for gig v3 files too
301        - added support for custom splits points for other dimensions than
302          velocity (gig v3 feature)
303        - added "smart midi" and "round robin keyboard" dimensions
304        - added new method File::DeleteGroupOnly() which only deletes the given
305          group but moves all its members to another group, the other method,
306          that is File::DeleteGroup() now removes not just the group, but also
307          all the samples that belong to that group
308        - fixed crash which occured on interfering File::DeleteSample() and
309          File::GetNextSample() calls (due to iterator invalidation)

315          when used from Instrument::AddRegion
316        - when saving, override the gig::Regions sample reference simply by
317          the region's first dimension region's sample (avoids an exception
318          when trying to save a new instrument)
319        - fixed AddDimension() method which did not fill out all mandatory
320          dimension definition fields
321    
322      * src/DLS.cpp, src/DLS.h:
323        - added Instrument::MoveRegion method

325          causing an exception when trying to save a new instrument
326    
327      * src/RIFF.cpp, src/RIFF.h:
328        - fixed RIFF::Chunk destructor which did not unregister previously
329          resized chunks, leading to a "zero size chunk" exception when
330          File::Save() was called
331        - added List::MoveSubChunk method
332    
333    Version 3.1.0 (24 Nov 2006)

339      * src/gig.cpp, src/gig.h:
340        - added support for more than one set of custom velocity splits
341          inside a region (for example different velocity split levels for
342          pedal up and pedal down)
343        - sample loop parameters are now taken from the DimensionRegion
344          instead of the wave chunk
345        - keyswitching dimension is changed from split type "normal" to
346          "bit"
347        - real support for 24 bit samples - samples are not truncated to
348          16 bits anymore
349        - support for reading of ".art" files. (Merging of .art and .gig
350          files are not implemented yet.)

371    Version 3.0.0 (28 Apr 2006)
372    
373      * general changes:
374        - added write support (that is for creating and modifying RIFF, DLS and
375          gig files)

377          files are now loaded even if mandatory RIFF chunks are missing
378        - fixed some memory management errors, one of them was causing a
379          crash when a multi-file gig was deallocated
380    
381      * src/gig.cpp, src/gig.h:
382        - fixed the GetVelocityCutoff function, it wasn't always using the

390          seeked instead of ordinary <artl> data chunks)
391        - added write support (highly experimental)
392    
393      * src/RIFF.cpp, src/RIFF.h:
394        - added write support
395        - Chunk::LoadChunkData() can now be called again to resize the buffer
396          after a Chunk::Resize() and before the File::Save() call to allow
397          placing the new data in the chunk's write buffer and perform the
398          resize and write operations in one rush
399    
400      * src/gigdump.cpp:
401        - fixed to show the correct amount of dimension regions instead of 32
402          (patch by James Wylder)

409    
410      * packaging changes:
411        - require automake (>= 1.5) for 'make -f Makefile.cvs'
