* src/gig.h, src/gig.cpp: support for up to 8 dimensions as introduced by
  Gig V3 (patch by Andreas Persson)

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
16 * src/gigdump.cpp:
17 - added output of UnityNote and FineTune
18
19 Version 1.0.0 (26 Nov 2004)
20
21 * packaging changes:
22 - renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name
23 'libgig' -> 'gig' as it's common practice to omit the 'lib' prefix
24 - fixed man pages automake install rule (which didn't work on Mandrake,
25 SuSE and Fedora)
26 - fixed generation of Doxygen API documentation (now also included in
27 RPM and Debian packages)
28
29 * src/gig.cpp, src/gig.h:
30 - fixed / improved accuracy of all three velocity to volume
31 transformation functions a.k.a. 'nonlinear','linear','special'
32 (patch by Andreas Persson)
33 - denormals are filtered from the velocity to volume tables
34 - bugfix for dimension region switching (wrong handling of the release
35 trigger dimension, no bit range check for dimensions of split type
36 'split_type_bit')
37 - fixed panorama value in DimensionRegion (invalid conversion from
38 signed 7 bit to signed 8 bit)
39 - added class attribute 'Layers' to class 'gig::Region'
40 - symbol prototyping of gig::Region (fixes build failure with qsampler)
41
42 * src/gigextract.cpp:
43 - added support for libsndfile (if libaudiofile and libsndfile are
44 available then libsndfile is preferred)
45
46 * src/gigdump.cpp:
47 - added printout for dimension informations (amount, type, bits, zones)
48 - added printout for velocity response curve parameters
49 - added printout for crossfade definitions
50 - added printout for panorama value for each DimensionRegion
51 - replaced printout of DLS Region layer by printout of amount of
52 Gigasampler layers
53
54 Version 0.7.1 (2 Jul 2004)
55
56 * packaging changes:
57 - added libgig.spec and libgig.pc package configurations for generating
58 Redhat packages
59 - header files included on installation.
60 - autotools-generated files removed from CVS repository.
61 - added support for generating Debian packages
62 - version of shared library can be set in configure.in
63
64 Version 0.7.0 (3 May 2004)
65
66 * general changes:
67 - various big endian specific corrections
68 (successfully tested now on PPC)
69 - minor adjustments to avoid compile errors on some systems
70 (using now pow() instead of powl() and --pedantic g++ compiler switch)
71 - libtoolized the library
72 - added man pages for the command line tools
73 (gigextract, gigdump, dlsdump, rifftree)
74
75 * src/gig.cpp, src/gig.h:
76 - fixed bug in decompression algorithm which caused it not to detect
77 the end of a stream
78 - added method GetVelocityAttenuation() to class 'DimensionRegion' which
79 takes the MIDI key velocity value as an argument and returns the
80 appropriate volume factor (0.0 ... 1.0) for the sample to be played
81 back, the velocity curve transformation functions used for this are
82 only an approximation so far
83 - fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and
84 'Sample::LoopSize' which reflected wrong values
85 - class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now
86 measured in sample points instead of byte offset
87 - renamed misleading attribute name 'Sample::MIDIPitchFraction' to
88 'Sample::FineTune'
89 - added class attribute 'Sample::LoopSize'
90 - added method GetInstrument(uint index) to class 'File'
91 - added ReadAndLoop() method to class 'Sample' which is an extension to
92 the normal Read() method to honor the sample's looping information
93 while streaming from disk
94 - changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and
95 'eg2_ctrl_t': replaced this huge enumeration by a structure which
96 reflects the MIDI controller number in case of an ordinary control
97 change controller (this saves a huge switch-case block in the
98 application of the library user)
99 - renamed following attributes in class 'DimensionRegion':
100 'AttenuationContol' -> 'AttenuationController',
101 'InvertAttenuationControl' -> 'InvertAttenuationController',
102 'AttenuationControlTreshold' -> 'AttenuationControllerThreshold'
103 - minor fix in API documentation for method GetVelocityAttenuation() in
104 class 'DimensionRegion'
105
106 * src/RIFF.cpp, src/RIFF.h:
107 - added additional API documentation
108 - minor fix in Chunk::Read() method (only a minor efficiency issue)
109
110 * src/gigdump.cpp:
111 - added printout of samples' looping informations
112
113 Version 0.6.0 (3 Nov 2003)
114
115 * initial release
