Wed Feb 15 13:21:31 2017 UTC (3 years, 9 months ago) by schoenebeck
File size: 28658 byte(s)
* gig.cpp: Instruments' default pitch bend range is now +-2 semi tones.
* Bumped version (4.0.0.svn12).

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
27 * src/DLS.cpp, src/DLS.h:
28 - Sample: wave pool offsets are now 64 bits (to allow support for files
29 larger than 4 GB).
30
31 * src/RIFF.cpp, src/RIFF.h:
32 - added support for RIFF files larger than 4 GB, by default the required
33 internal RIFF file offset size is automatically detected (that is RIFF
34 files < 4 GB automatically use 32 bit offsets while files >= 4 GB
35 automatically use 64 bit offsets), a particular offset size can be forced
36 with a new option added to the RIFF File constructor though
37 - when saving a modified, grown RIFF file, the temporary file size during
38 Save() operation will no longer be larger than the final grown file size
39
40 * src/tools/akaidump.cpp, src/tools/akaiextract.cpp:
41 - improved output of non-ascii characters in usage messages
42 - fixed printf format strings
43
44 * src/tools/korg2gig.cpp:
45 - fixed c++11 narrowing warnings
46 - fixed fine tuning which was not translated at all
47
48 * src/tools/gigdump.cpp:
49 - additionally print VelocityUpperLimit and DimensionUpperLimits of all
50 dimension regions
51 - additionally print RIFF chunk file offset and RIFF chunk size of sample
52 data
53 - added and implemented new parameter "--verify" which allows to check
54 the raw wave form data integrity of all samples
55 - added and implemented new parameter "--rebuild-checksums" which allows
56 to recalculate the CRC32 checksum of all samples' raw wave data and
57 rebuilding the gig file's global checksum table (i.e. in case the
58 file's checksum table was damaged)
59 - print samples' CRC32 checksums
60
61 * src/tools/gigextract.cpp:
62 - Fix: if sample name contains a path separator (slash or backslash) then
63 replace them by a minus sign to avoid file system issues.
64
65 * packaging changes:
66 - Automake: set environment variable GCC_COLORS=auto to allow GCC to
67 auto detect whether it (sh/c)ould output its messages in color.
68
69 Version 4.0.0 (14 Jul 2015)
70 * general changes:
71 - minor Makefile fix for parallel make

92
93 * SoundFont file format:
94 - initial implementation
95 - changed region lookup API to avoid malloc in RT threads
96 - fixed GetEG1Sustain which didn't return correct value
97 - bugfix: GetPan always returned -1, 0 or 1

100 - initial support for sample based instruments in KORG's file format
101 (.KMP and .KSF files)
102
103 * AKAI file format:
104 - Added Linux/POSIX ported version of libakai. Note that libakai is released
105 under LGPL terms while libgig is released under GPL terms. To handle this
106 license difference appropriately the AKAI support part is built as
107 separate DLL (.so file).
108 - Fixed Mac OSX support so that the Akai lib files and tools compile without
109 any exotic third party libraries.
110 - Fixed various compilation errors for Windows.
111 - POSIX fix: open() requires third (mode) argument if used with O_CREAT

209 bi-directional (a.k.a. 'pingpong') loop type (fixes #102)
210
211 * src/RIFF.cpp, src/RIFF.h:
212 - bugfix: saving to the same file after the file size had been

282 - write support: DLSID is now generated on the file and the
283 instruments
284 - write support: improved the default values for dimension region
285 parameters
286 - more write support fixes: crossfade parameters were not saved,

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

336 - fixed constructor for Region, which did not initialize correctly
337 when used from Instrument::AddRegion
338 - when saving, override the gig::Regions sample reference simply by
339 the region's first dimension region's sample (avoids an exception
340 when trying to save a new instrument)

526 - added command line switch -v to show gigextract's revision and the
527 used libgig version
528
529 Version 1.0.0 (26 Nov 2004)
530
531 * packaging changes:
532 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
533 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
534 - fixed man pages automake install rule (which didn't work on Mandrake,
535 SuSE and Fedora)
536 - fixed generation of Doxygen API documentation (now also included in
537 RPM and Debian packages)
538
539 * src/gig.cpp, src/gig.h:
540 - fixed / improved accuracy of all three velocity to volume
541 transformation functions a.k.a. 'nonlinear','linear','special'
542 (patch by Andreas Persson)
543 - denormals are filtered from the velocity to volume tables
544 - bugfix for dimension region switching (wrong handling of the release
545 trigger dimension, no bit range check for dimensions of split type
546 'split_type_bit')
547 - fixed panorama value in DimensionRegion (invalid conversion from
548 signed 7 bit to signed 8 bit)
549 - added class attribute 'Layers' to class 'gig::Region'
550 - symbol prototyping of gig::Region (fixes build failure with qsampler)
551
552 * src/gigextract.cpp:
553 - added support for libsndfile (if libaudiofile and libsndfile are
554 available then libsndfile is preferred)
555
556 * src/gigdump.cpp:
557 - added printout for dimension informations (amount, type, bits, zones)
558 - added printout for velocity response curve parameters
559 - added printout for crossfade definitions
560 - added printout for panorama value for each DimensionRegion
561 - replaced printout of DLS Region layer by printout of amount of
562 Gigasampler layers
563
564 Version 0.7.1 (2 Jul 2004)
565
566 * packaging changes:
567 - added libgig.spec and libgig.pc package configurations for generating
568 Redhat packages
569 - header files included on installation.
570 - autotools-generated files removed from CVS repository.
571 - added support for generating Debian packages
572 - version of shared library can be set in configure.in
573
574 Version 0.7.0 (3 May 2004)
575
576 * general changes:
577 - various big endian specific corrections
578 (successfully tested now on PPC)
579 - minor adjustments to avoid compile errors on some systems
580 (using now pow() instead of powl() and --pedantic g++ compiler switch)
581 - libtoolized the library
582 - added man pages for the command line tools
583 (gigextract, gigdump, dlsdump, rifftree)
584
585 * src/gig.cpp, src/gig.h:
586 - fixed bug in decompression algorithm which caused it not to detect
587 the end of a stream
588 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
589 takes the MIDI key velocity value as an argument and returns the
590 appropriate volume factor (0.0 ... 1.0) for the sample to be played
591 back, the velocity curve transformation functions used for this are
592 only an approximation so far
593 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
594 'Sample::LoopSize' which reflected wrong values
595 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
596 measured in sample points instead of byte offset
597 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
598 'Sample::FineTune'
599 - added class attribute 'Sample::LoopSize'
600 - added method GetInstrument(uint index) to class 'File'
601 - added ReadAndLoop() method to class 'Sample' which is an extension to
602 the normal Read() method to honor the sample's looping information
603 while streaming from disk
604 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
605 'eg2_ctrl_t': replaced this huge enumeration by a structure which
606 reflects the MIDI controller number in case of an ordinary control
607 change controller (this saves a huge switch-case block in the
608 application of the library user)
609 - renamed following attributes in class 'DimensionRegion':
610 'AttenuationContol' -> 'AttenuationController',
611 'InvertAttenuationControl' -> 'InvertAttenuationController',
612 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
613 - minor fix in API documentation for method GetVelocityAttenuation() in
614 class 'DimensionRegion'
615
616 * src/RIFF.cpp, src/RIFF.h:
617 - added additional API documentation
618 - minor fix in Chunk::Read() method (only a minor efficiency issue)
619
620 * src/gigdump.cpp:
621 - added printout of samples' looping informations
622
623 Version 0.6.0 (3 Nov 2003)
624
625 * initial release
