Sat Apr 15 20:17:05 2017 UTC (6 years, 11 months ago) by schoenebeck
File size: 28852 byte(s)
* src/gig.cpp: Fixed CRC checksums being wrong sometimes.
* src/tools/gig2stereo.cpp: Also merge mono sample pairs
  with non matching loop information if argument
  "--incompatible" was given.
* Bumped version (4.0.0.svn13).

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

105 - initial support for sample based instruments in KORG's file format
106 (.KMP and .KSF files)
107
108 * AKAI file format:
109 - Added Linux/POSIX ported version of libakai. Note that libakai is released
110 under LGPL terms while libgig is released under GPL terms. To handle this
111 license difference appropriately the AKAI support part is built as
112 separate DLL (.so file).
113 - Fixed Mac OSX support so that the Akai lib files and tools compile without
114 any exotic third party libraries.

164 (chunks at wrong location in the RIFF tree).
165
166 * src/SF.cpp, src/SF.h:
167 - added new method Sample::ReadNoClear()
168
169 * src/RIFF.cpp, src/RIFF.h:

184 one allows to move the subchunk from the current list to another list
185 - POSIX: only assume -1 result value as error on open() calls
186 - POSIX: show operating system's error reason if opening a file failed

288 instruments
289 - write support: improved the default values for dimension region
290 parameters

293 when dimensions were added or deleted, v3 wave pool offsets were
294 not saved correctly
295 - write support: 24 bit samples can now be written

306 parent Region
307 - fixed Instrument::UpdateRegionKeyTable() method which did not reset

329 velocity (gig v3 feature)
330 - added "smart midi" and "round robin keyboard" dimensions
331 - added new method File::DeleteGroupOnly() which only deletes the given
332 group but moves all its members to another group, the other method,

339 with the group
340 - added Instrument::MoveRegion method
341 - fixed constructor for Region, which did not initialize correctly
342 when used from Instrument::AddRegion
343 - when saving, override the gig::Regions sample reference simply by
344 the region's first dimension region's sample (avoids an exception
345 when trying to save a new instrument)
346 - fixed AddDimension() method which did not fill out all mandatory
347 dimension definition fields
348
349 * src/DLS.cpp, src/DLS.h:
350 - added Instrument::MoveRegion method
351 - fixed software info field which was wrongly stored on instruments,
352 causing an exception when trying to save a new instrument
353

533
534 Version 1.0.0 (26 Nov 2004)
535
536 * packaging changes:
537 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
538 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
539 - fixed man pages automake install rule (which didn't work on Mandrake,
540 SuSE and Fedora)
541 - fixed generation of Doxygen API documentation (now also included in
542 RPM and Debian packages)
543
544 * src/gig.cpp, src/gig.h:
545 - fixed / improved accuracy of all three velocity to volume
546 transformation functions a.k.a. 'nonlinear','linear','special'
547 (patch by Andreas Persson)
548 - denormals are filtered from the velocity to volume tables
549 - bugfix for dimension region switching (wrong handling of the release
550 trigger dimension, no bit range check for dimensions of split type
551 'split_type_bit')
552 - fixed panorama value in DimensionRegion (invalid conversion from
553 signed 7 bit to signed 8 bit)
554 - added class attribute 'Layers' to class 'gig::Region'
555 - symbol prototyping of gig::Region (fixes build failure with qsampler)
556
557 * src/gigextract.cpp:
558 - added support for libsndfile (if libaudiofile and libsndfile are
559 available then libsndfile is preferred)
560
561 * src/gigdump.cpp:
562 - added printout for dimension informations (amount, type, bits, zones)
563 - added printout for velocity response curve parameters
564 - added printout for crossfade definitions
565 - added printout for panorama value for each DimensionRegion
566 - replaced printout of DLS Region layer by printout of amount of
567 Gigasampler layers
568
569 Version 0.7.1 (2 Jul 2004)
570
571 * packaging changes:
572 - added libgig.spec and libgig.pc package configurations for generating
573 Redhat packages
574 - header files included on installation.
575 - autotools-generated files removed from CVS repository.
576 - added support for generating Debian packages
577 - version of shared library can be set in configure.in
578
579 Version 0.7.0 (3 May 2004)
580
581 * general changes:
582 - various big endian specific corrections
583 (successfully tested now on PPC)
584 - minor adjustments to avoid compile errors on some systems
585 (using now pow() instead of powl() and --pedantic g++ compiler switch)
586 - libtoolized the library
587 - added man pages for the command line tools
588 (gigextract, gigdump, dlsdump, rifftree)
589
590 * src/gig.cpp, src/gig.h:
591 - fixed bug in decompression algorithm which caused it not to detect
592 the end of a stream
593 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
594 takes the MIDI key velocity value as an argument and returns the
595 appropriate volume factor (0.0 ... 1.0) for the sample to be played
596 back, the velocity curve transformation functions used for this are
597 only an approximation so far
598 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
599 'Sample::LoopSize' which reflected wrong values
600 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
601 measured in sample points instead of byte offset
602 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
603 'Sample::FineTune'
604 - added class attribute 'Sample::LoopSize'
605 - added method GetInstrument(uint index) to class 'File'
606 - added ReadAndLoop() method to class 'Sample' which is an extension to
607 the normal Read() method to honor the sample's looping information
608 while streaming from disk
609 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
610 'eg2_ctrl_t': replaced this huge enumeration by a structure which
611 reflects the MIDI controller number in case of an ordinary control
612 change controller (this saves a huge switch-case block in the
613 application of the library user)
614 - renamed following attributes in class 'DimensionRegion':
615 'AttenuationContol' -> 'AttenuationController',
616 'InvertAttenuationControl' -> 'InvertAttenuationController',
617 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
618 - minor fix in API documentation for method GetVelocityAttenuation() in
619 class 'DimensionRegion'
620
621 * src/RIFF.cpp, src/RIFF.h:
622 - added additional API documentation
623 - minor fix in Chunk::Read() method (only a minor efficiency issue)
624
625 * src/gigdump.cpp:
626 - added printout of samples' looping informations
627
628 Version 0.6.0 (3 Nov 2003)
629
630 * initial release
