Fri Feb 4 00:21:30 2005 UTC (15 years, 5 months ago) by schoenebeck
File size: 5332 byte(s)
* src/gig.cpp:
  - another memory leak fix
  - duplicated memory free fix
  - tiny fix in decompression buffer reallocation
(patch by "Gene" a.k.a Anders Alm)

1 Version CVS HEAD (?)
2
3 * src/gig.cpp, src/gig.h:
4 - experimental support for Gigasampler v3 format;
5 64 bit file offsets are truncated to 32 bit, 24 bit samples are
6 truncated to 16 bit, up to 8 dimensions are read, additional
7 articulation informations are ignored at the moment
8 (patch by Andreas Persson)
9 - added some file format compatibility checks
10 - fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually
11 never used, because the necessary check was made before
12 initialization)
13 - fixed crossfade points order (structure for big endian and little
14 endian systems was interchanged)
15 - fixed some memory leaks (patch by 'Gene', a.k.a Anders Alm)
16 - fixed crash which occured when patches did not have a sample assigned
17 to their region or dimension region (patch by Andreas Persson)
18
19 * src/gigdump.cpp:
20 - added output of UnityNote and FineTune
21
22 Version 1.0.0 (26 Nov 2004)
23
24 * packaging changes:
25 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
26 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
27 - fixed man pages automake install rule (which didn't work on Mandrake,
28 SuSE and Fedora)
29 - fixed generation of Doxygen API documentation (now also included in
30 RPM and Debian packages)
31
32 * src/gig.cpp, src/gig.h:
33 - fixed / improved accuracy of all three velocity to volume
34 transformation functions a.k.a. 'nonlinear','linear','special'
35 (patch by Andreas Persson)
36 - denormals are filtered from the velocity to volume tables
37 - bugfix for dimension region switching (wrong handling of the release
38 trigger dimension, no bit range check for dimensions of split type
39 'split_type_bit')
40 - fixed panorama value in DimensionRegion (invalid conversion from
41 signed 7 bit to signed 8 bit)
42 - added class attribute 'Layers' to class 'gig::Region'
43 - symbol prototyping of gig::Region (fixes build failure with qsampler)
44
45 * src/gigextract.cpp:
46 - added support for libsndfile (if libaudiofile and libsndfile are
47 available then libsndfile is preferred)
48
49 * src/gigdump.cpp:
50 - added printout for dimension informations (amount, type, bits, zones)
51 - added printout for velocity response curve parameters
52 - added printout for crossfade definitions
53 - added printout for panorama value for each DimensionRegion
54 - replaced printout of DLS Region layer by printout of amount of
55 Gigasampler layers
56
57 Version 0.7.1 (2 Jul 2004)
58
59 * packaging changes:
60 - added libgig.spec and libgig.pc package configurations for generating
61 Redhat packages
62 - header files included on installation.
63 - autotools-generated files removed from CVS repository.
64 - added support for generating Debian packages
65 - version of shared library can be set in configure.in
66
67 Version 0.7.0 (3 May 2004)
68
69 * general changes:
70 - various big endian specific corrections
71 (successfully tested now on PPC)
72 - minor adjustments to avoid compile errors on some systems
73 (using now pow() instead of powl() and --pedantic g++ compiler switch)
74 - libtoolized the library
75 - added man pages for the command line tools
76 (gigextract, gigdump, dlsdump, rifftree)
77
78 * src/gig.cpp, src/gig.h:
79 - fixed bug in decompression algorithm which caused it not to detect
80 the end of a stream
81 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
82 takes the MIDI key velocity value as an argument and returns the
83 appropriate volume factor (0.0 ... 1.0) for the sample to be played
84 back, the velocity curve transformation functions used for this are
85 only an approximation so far
86 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
87 'Sample::LoopSize' which reflected wrong values
88 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
89 measured in sample points instead of byte offset
90 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
91 'Sample::FineTune'
92 - added class attribute 'Sample::LoopSize'
93 - added method GetInstrument(uint index) to class 'File'
94 - added ReadAndLoop() method to class 'Sample' which is an extension to
95 the normal Read() method to honor the sample's looping information
96 while streaming from disk
97 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
98 'eg2_ctrl_t': replaced this huge enumeration by a structure which
99 reflects the MIDI controller number in case of an ordinary control
100 change controller (this saves a huge switch-case block in the
101 application of the library user)
102 - renamed following attributes in class 'DimensionRegion':
103 'AttenuationContol' -> 'AttenuationController',
104 'InvertAttenuationControl' -> 'InvertAttenuationController',
105 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
106 - minor fix in API documentation for method GetVelocityAttenuation() in
107 class 'DimensionRegion'
108
109 * src/RIFF.cpp, src/RIFF.h:
110 - added additional API documentation
111 - minor fix in Chunk::Read() method (only a minor efficiency issue)
112
113 * src/gigdump.cpp:
114 - added printout of samples' looping informations
115
116 Version 0.6.0 (3 Nov 2003)
117
118 * initial release
