# 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        - print compiler warning if no RTTI available
11        - Fixed potential crash in command line tools gig2stereo, korg2gig,
12          korgdump and sf2extract.
13    
14      * src/gig.cpp, src/gig.h:
15        - fixed bug in Script::SetGroup: the script chunk wasn't moved
16        - fixed compilation error with clang 3.4
17        - GIG FORMAT EXTENSION: added support for saving gig file larger than 4 GB
18          as one single monolithic gig file. In case .gig file is >= 2GB expect a
19          large monolithic file, otherwise if .gig file is < 2 GB check for
20          "extension" files (.gx01, .gx02, ...) instead.
21        - fixed Region::UpdateUpdateVelocityTable() which did not work correctly
22          if there were dimensions after the velocity dimension: it only created
23          valid velocity tables for cases of dimensions lower than the velocity
24          dimension.
25        - added new method Sample::VerifyWaveData() which allows to check whether
26          a sample had been damaged for some reason
27        - Fix: samples' CRC checksums were damaged on file structure changes.
28        - Fix: samples' CRC checksums were misordered when a Sample was deleted.
29        - Added new method Sample::GetWaveDataCRC32Checksum().
30        - Changed default value of EG2Release (filter release time) to 60s.
31        - Instruments' default pitch bend range is now +-2 semi tones.
32        - Fixed CRC checksums being wrong sometimes.
33        - Fix: method File::AddContentOf() did not clone script groups and scripts
34          of passed original file.
35        - Added support for serializing & deserializing DimensionRegion
36          objects (and crossfade_t and leverage_ctrl_t objects).
37        - Added enum reflection API functions for retrieving enum declaration type
38          information at runtime (enumCount(), enumKey(), enumKeys(), enumValue()).
39    
40      * src/DLS.cpp, src/DLS.h:
41        - Sample: wave pool offsets are now 64 bits (to allow support for files
42          larger than 4 GB).
43          
44      * src/RIFF.cpp, src/RIFF.h:
45        - added support for RIFF files larger than 4 GB, by default the required
46          internal RIFF file offset size is automatically detected (that is RIFF
47          files < 4 GB automatically use 32 bit offsets while files >= 4 GB
48          automatically use 64 bit offsets), a particular offset size can be forced
49          with a new option added to the RIFF File constructor though
50        - when saving a modified, grown RIFF file, the temporary file size during
51          Save() operation will no longer be larger than the final grown file size
52    
53      * src/Serialization.cpp, src/Serialization.h:
54        - Archive: Added method isModified().
55        - Archive: Added method setAutoValue().
56        - Archive: Added method setIntValue().
57        - Archive: Added method setRealValue().
58        - Archive: Added method setBoolValue().
59        - Archive: Added method setEnumValue().
60        - Archive: Added method valueAsString().
61        - Archive::rawData(): Automatically re-encode new raw data stream if
62          archive had been modified (i.e. by remove(), setAutoValue(), etc.).
63        - Object: Added method memberByUID().
64        - Object: remove() method is now protected.
65        - Archive: Added method removeMember().
66        - Archive: Added methods name() and setName().
67        - Archive: Added methods comment() and setComment().
68        - Archive: Added methods timeStampCreated(), timeStampModified(),
69          dateTimeCreated() and dateTimeModified().
70        - Archive: Added methods valueAsInt(), valueAsReal() and valueAsBool().
71        - DataType: Implemented demangling C++ type names (for methods
72          asLongDescr() and customTypeName(bool demangle=false)).
73        - Archive::setAutoValue(): Handle human readable boolean text
74          representations like "yes", "no", "true", "false" as expected.
75    
76      * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
77        - improved output of non-ascii characters in usage messages
78        - fixed printf format strings
79

86          dimension regions
87        - additionally print RIFF chunk file offset and RIFF chunk size of sample
88          data
89        - added and implemented new parameter "--verify" which allows to check
90          the raw wave form data integrity of all samples
91        - added and implemented new parameter "--rebuild-checksums" which allows
92          to recalculate the CRC32 checksum of all samples' raw wave data and
93          rebuilding the gig file's global checksum table (i.e. in case the
94          file's checksum table was damaged)
95        - print samples' CRC32 checksums
96    
97      * src/tools/gigextract.cpp:
98        - Fix: if sample name contains a path separator (slash or backslash) then
99          replace them by a minus sign to avoid file system issues.
100    
101      * src/tools/gig2stereo.cpp:
102        - Also merge mono sample pairs with non matching loop information if
103          argument --incompatible was given.
104    
105      * packaging changes:
106        - Automake: set environment variable GCC_COLORS=auto to allow GCC to

142    
143      * AKAI file format:
144        - Added Linux/POSIX ported version of libakai. Note that libakai is released
145          under LGPL terms while libgig is released under GPL terms. To handle this
146          license difference appropriately the AKAI support part is built as
147          separate DLL (.so file).
148        - Fixed Mac OSX support so that the Akai lib files and tools compile without
149          any exotic third party libraries.
150        - Fixed various compilation errors for Windows.
151        - POSIX fix: open() requires third (mode) argument if used with O_CREAT

153    
154      * src/gig.cpp:
155        - bugfix: VCF velocity dynamic range and VCF velocity curve
156          weren't saved correctly

164          wrong textual group name
165        - added new method File::AddContentOf() for merging .gig files
166        - GIG FORMAT EXTENSION: added additional MIDI controllers for leverage
167          controller types (only works with LinuxSampler & gigedit, will not

185          (chunks at wrong location in the RIFF tree).
186        - Added new method Instrument::MoveTo() which allows to rearrange the order
187          of instruments within the same gig file.
188    
189      * src/DLS.cpp, src/DLS.h:
190        - added new method File::GetFileName()
191        - fixed minor "memory leak on exception" bug found with cppcheck
192        - added new method File::GetExtensionFile(int index)

211          later on without passing a file name
212        - added new method File::IsNew()
213        - added support for loading RIFF-like files with a bit different layout
214          than "real" RIFF files (used for KORG format support)
215        - added new method Chunk::GetFile()
216        - added new method Chunk::GetLayout()
217        - added 2nd, alternative method for List::MoveSubChunk(), the old 1st one

225        - Cleanup of an old DLL binary backward compatibility hack.
226    
227      * src/gigextract.cpp:
228        - export sample loop, unity note and fine tune with libsndfile

244        - bugfix: removed another iterator invalidation in DeleteSample
245        - bugfix in Sample::LoadSampleData*(): reset sample read position to
246          sample start before trying to (re)load sample data from file (#82)
247        - bugfix: EG3 depth parameter was not saved correctly
248        - fixed crash which occured when streaming a gig sample with
249          bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
250    
251      * src/RIFF.cpp, src/RIFF.h:

257          decreased sometimes also made the file corrupt!
258        - bugfix: undefined behavior (e.g. endless loop) when opening zero
259          length files, now throws a RIFF::Exception instead (fixes bug #121)
260        - bugfix: destructor for base class RIFF::Chunk accessed members
261          of derived class RIFF::File, which is bad, and caused crashes
262          when using Visual C++
263        - bugfix: files that contain zero length RIFF lists were not read
264          correctly (fixes #127) (bug was introduced 2009-03-13)
265    
266    Version 3.2.1 (5 Dec 2007)
267    
268      * src/RIFF.cpp, src/RIFF.h:
269        - avoid Windows to perform unnecessary file stream caching which would
270          decrease disk streaming performance on Windows systems otherwise
271    
272      * src/gig.cpp, src/gig.h:
273        - added File::SetAutoLoad() and File::GetAutoLoad() for allowing

306          instrument constructors
307        - clear unused fields when saving samples and regions

316        - write support: two previously unknown fields in dimension
317          definition are now saved
318        - added constants for gig file versions
319        - write support: the 3crc and einf chunks are now created or
320          updated when a file is saved (3crc contains sample checksums,
321          einf contains file statistics)
322        - write support: DLSID is now generated on the file and the
323          instruments
324        - write support: improved the default values for dimension region
325          parameters
326        - more write support fixes: crossfade parameters were not saved,

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

335          where incorrectly saved due to an operator precedence mistake
336        - DeleteSample now removes all references to the deleted sample
337        - AddDimension now copies all parameters from existing dimension
338          regions and also makes sure that the samplechannel dimension is
339          placed first in the list of dimensions.
340        - added method GetParent() to class 'DimensionRegion', which returns its
341          parent Region
342        - fixed Instrument::UpdateRegionKeyTable() method which did not reset
343          unused areas
344        - added various setter methods to DimensionRegion class which take care
345          of updating lookup tables / caches.
346    
347      * src/RIFF.cpp, src/RIFF.h:
348        - added File::SetByteOrder method
349        - Windows fix: saving a new file didn't work
350    
351      * src/gigdump.cpp:

358          (provided Dev-C++ + mingw project file)
359        - only export relevant files to Doxygen API documentation
360    
361      * src/gig.cpp, src/gig.h:
362        - custom velocity splits now works for gig v3 files too
363        - added support for custom splits points for other dimensions than
364          velocity (gig v3 feature)
365        - added "smart midi" and "round robin keyboard" dimensions
366        - added new method File::DeleteGroupOnly() which only deletes the given
367          group but moves all its members to another group, the other method,
368          that is File::DeleteGroup() now removes not just the group, but also
369          all the samples that belong to that group
370        - fixed crash which occured on interfering File::DeleteSample() and
371          File::GetNextSample() calls (due to iterator invalidation)
372        - fixed group names which were not saved
373        - fixed group destructor which did not remove the RIFF chunk associated
374          with the group

377          when used from Instrument::AddRegion
378        - when saving, override the gig::Regions sample reference simply by
379          the region's first dimension region's sample (avoids an exception
380          when trying to save a new instrument)
381        - fixed AddDimension() method which did not fill out all mandatory
382          dimension definition fields
383

387          causing an exception when trying to save a new instrument
388    
389      * src/RIFF.cpp, src/RIFF.h:
390        - fixed RIFF::Chunk destructor which did not unregister previously
391          resized chunks, leading to a "zero size chunk" exception when
392          File::Save() was called
393        - added List::MoveSubChunk method
394    
395    Version 3.1.0 (24 Nov 2006)

403          inside a region (for example different velocity split levels for
404          pedal up and pedal down)
405        - sample loop parameters are now taken from the DimensionRegion
406          instead of the wave chunk
407        - keyswitching dimension is changed from split type "normal" to
408          "bit"
409        - real support for 24 bit samples - samples are not truncated to
410          16 bits anymore
411        - support for reading of ".art" files. (Merging of .art and .gig
412          files are not implemented yet.)
413        - several fixes for the write support
414        - support for sample groups added
415    
416      * src/DLS.cpp, src/DLS.h:
417        - support for reading of ".art" files
418        - removed incorrect use of memccpy in the write support (patch by
419          Jeremy Kerr)
420        - several fixes for the write support
421    
422      * src/gigextract.cpp:
423        - real support for 24 bit samples
424    
425      * src/gigdump.cpp:
426        - print global file informations
427        - print sample groups
428    
429      * general changes:
430        - added CPPUnit test cases (at the moment primarily for automatic check
431          of Gigasampler write support)
432    
433    Version 3.0.0 (28 Apr 2006)
434    
435      * general changes:
436        - added write support (that is for creating and modifying RIFF, DLS and
437          gig files)
438        - loading DLS and gig files is now much more permissive, DLS and gig
439          files are now loaded even if mandatory RIFF chunks are missing
440        - fixed some memory management errors, one of them was causing a
441          crash when a multi-file gig was deallocated
442    
443      * src/gig.cpp, src/gig.h:
444        - fixed the GetVelocityCutoff function, it wasn't always using the
445          VCFVelocityScale parameter when no cutoff controller was defined
446        - support for the gig v3 feature to have a number of dimension
447          splits not equal to a power of two
448        - added write support (highly experimental)
449    
450      * src/DLS.cpp, src/DLS.h:
451        - fixed loading of Articulation Connections (<artl> list chunks were
452          seeked instead of ordinary <artl> data chunks)
453        - added write support (highly experimental)
454    
455      * src/RIFF.cpp, src/RIFF.h:
456        - added write support
457        - Chunk::LoadChunkData() can now be called again to resize the buffer
458          after a Chunk::Resize() and before the File::Save() call to allow
459          placing the new data in the chunk's write buffer and perform the
460          resize and write operations in one rush
461    
462      * src/gigdump.cpp:
463        - fixed to show the correct amount of dimension regions instead of 32
464          (patch by James Wylder)
465    
466      * src/dlsdump.cpp:
467        - show for every region the name of the referenced sample
468        - show file name in quotation marks
469    
470    Version 2.0.2 (15 Aug 2005)
471    
472      * packaging changes:
473        - require automake (>= 1.5) for 'make -f Makefile.cvs'
474          (mandatory for 'dist-bzip2' automake option)
475    
476      * src/gig.cpp, src/gig.h:
477        - support for gig v3 multi-file format (.gig, .gx01, .gx02, ...),
478          the extension files are read automatically when the samples are
479          loaded
480        - fixed the 24 bit decompression, the result should now be exact
481          instead of an approximation
482        - added VCFCutoffControllerInvert parameter and GetVelocityCutoff
483          function to DimensionRegion
484    
485      * src/DLS.cpp, src/DLS.h:
486        - the upper bits of the pool table indices are read (used as
487          extension file numbers for gig v3)
488    
489      * src/RIFF.cpp, src/RIFF.h:
490        - the file name is remembered in the RIFF::File object
491    
492    Version 2.0.1 (12 Jun 2005)
493    
494      * packaging changes:
495        - include debian/ directory on 'make dist'
496        - create a bzip2 tarball on 'make dist'
497    
498      * src/gigextract.cpp:
499        - show also version of libsndfile or build version of libaudiofile when
500          using the -v switch
501        - fixed mutual link dependency to libsndfile / libaudiofile
502    
503      * src/gig.cpp, src/gig.h:
504        - added DimensionRegion::GetVelocityRelease function
505
