| 5 |
|
added ldconfig to post-(un)install steps on libgig.spec (RPM) |
| 6 |
|
|
| 7 |
|
* src/gig.cpp, src/gig.h: |
| 8 |
|
- added support for more than one set of custom velocity splits |
| 9 |
|
inside a region (for example different velocity split levels for |
| 10 |
|
pedal up and pedal down) |
| 11 |
|
- sample loop parameters are now taken from the DimensionRegion |
| 12 |
|
instead of the wave chunk |
| 13 |
|
- keyswitching dimension is changed from split type "normal" to |
| 14 |
|
"bit" |
| 15 |
|
- real support for 24 bit samples - samples are not truncated to |
| 16 |
|
16 bits anymore |
| 17 |
|
- support for reading of ".art" files. (Merging of .art and .gig |
| 18 |
|
files are not implemented yet.) |
| 19 |
|
- several fixes for the write support |
| 20 |
|
- support for sample groups added |
| 21 |
|
|
| 22 |
|

| 24 |
|
- removed incorrect use of memccpy in the write support (patch by |
| 25 |
|
Jeremy Kerr) |
| 26 |
|
- several fixes for the write support |
| 27 |
|
|
| 28 |
|
* src/gigextract.cpp: |
| 29 |

| 33 |
|
- print sample groups |
| 34 |
|
|
| 35 |
|
* general changes: |
| 36 |
|
- added CPPUnit test cases (at the moment primarily for automatic check |
| 37 |
|
of Gigasampler write support) |
| 38 |
|
|
| 39 |
|
Version 3.0.0 (28 Apr 2006) |
| 40 |
|
|
| 41 |
|
* general changes: |
| 42 |
|
- added write support (that is for creating and modifying RIFF, DLS and |
| 43 |
|
gig files) |
| 44 |
|
- loading DLS and gig files is now much more permissive, DLS and gig |
| 45 |
|
files are now loaded even if mandatory RIFF chunks are missing |
| 46 |
|
- fixed some memory management errors, one of them was causing a |
| 47 |
|
crash when a multi-file gig was deallocated |
| 48 |
|
|
| 49 |
|
* src/gig.cpp, src/gig.h: |
| 50 |
|
- fixed the GetVelocityCutoff function, it wasn't always using the |
| 51 |
|
VCFVelocityScale parameter when no cutoff controller was defined |
| 52 |
|
- support for the gig v3 feature to have a number of dimension |
| 53 |
|
splits not equal to a power of two |
| 54 |
|
- added write support (highly experimental) |
| 55 |
|
|
| 56 |
|
* src/DLS.cpp, src/DLS.h: |
| 57 |
|
- fixed loading of Articulation Connections (<artl> list chunks were |
| 58 |
|
seeked instead of ordinary <artl> data chunks) |
| 59 |
|
- added write support (highly experimental) |
| 60 |
|
|
| 61 |
|
* src/RIFF.cpp, src/RIFF.h: |
| 62 |
|
- added write support |
| 63 |
|
- Chunk::LoadChunkData() can now be called again to resize the buffer |
| 64 |
|
after a Chunk::Resize() and before the File::Save() call to allow |
| 65 |
|
placing the new data in the chunk's write buffer and perform the |
| 66 |
|
resize and write operations in one rush |
| 67 |
|
|
| 68 |
|
* src/gigdump.cpp: |
| 69 |
|
- fixed to show the correct amount of dimension regions instead of 32 |
| 70 |
|
(patch by James Wylder) |
| 71 |
|
|
| 72 |
|
* src/dlsdump.cpp: |
| 73 |
|
- show for every region the name of the referenced sample |
| 74 |
|
- show file name in quotation marks |
| 75 |
|
|
| 76 |
|

| 84 |
|
the extension files are read automatically when the samples are |
| 85 |
|
loaded |
| 86 |
|
- fixed the 24 bit decompression, the result should now be exact |
| 87 |
|
instead of an approximation |
| 88 |
|
- added VCFCutoffControllerInvert parameter and GetVelocityCutoff |
| 89 |
|
function to DimensionRegion |

|
(patch by Andreas Persson) |
| 125 |
|
- added some file format compatibility checks |
| 126 |
|
- fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually |
| 127 |
|
never used, because the necessary check was made before |
| 128 |

|
Version 1.0.0 (26 Nov 2004) |
| 176 |
|
|
| 177 |

| 178 |
|
- renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name |

|
- denormals are filtered from the velocity to volume tables |
| 190 |
|
- bugfix for dimension region switching (wrong handling of the release |

|
Version 0.7.1 (2 Jul 2004) |
| 211 |
|
|
| 212 |
|
* packaging changes: |
| 213 |
|
- added libgig.spec and libgig.pc package configurations for generating |
| 214 |
|
Redhat packages |
| 215 |
|
- header files included on installation. |
| 216 |
|
- autotools-generated files removed from CVS repository. |
| 217 |
|
- added support for generating Debian packages |
| 218 |
|
- version of shared library can be set in configure.in |
| 219 |
|
|
| 220 |
|
Version 0.7.0 (3 May 2004) |
| 221 |
|
|
| 222 |
|
* general changes: |
| 223 |
|
- various big endian specific corrections |
| 224 |
|
(successfully tested now on PPC) |
| 225 |
|
- minor adjustments to avoid compile errors on some systems |
| 226 |
|
(using now pow() instead of powl() and --pedantic g++ compiler switch) |
| 227 |
|
- libtoolized the library |
| 228 |
|
- added man pages for the command line tools |
| 229 |
|
(gigextract, gigdump, dlsdump, rifftree) |
| 230 |
|
|
| 231 |
|
* src/gig.cpp, src/gig.h: |
| 232 |
|
- fixed bug in decompression algorithm which caused it not to detect |
| 233 |
|
the end of a stream |
| 234 |
|
- added method GetVelocityAttenuation() to class 'DimensionRegion' which |
| 235 |
|
takes the MIDI key velocity value as an argument and returns the |
| 236 |
|
appropriate volume factor (0.0 ... 1.0) for the sample to be played |
| 237 |
|
back, the velocity curve transformation functions used for this are |
| 238 |
|
only an approximation so far |
| 239 |
|
- fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and |
| 240 |
|
'Sample::LoopSize' which reflected wrong values |
| 241 |
|
- class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now |
| 242 |
|
measured in sample points instead of byte offset |
| 243 |
|
- renamed misleading attribute name 'Sample::MIDIPitchFraction' to |
| 244 |
|
'Sample::FineTune' |
| 245 |
|
- added class attribute 'Sample::LoopSize' |
| 246 |
|
- added method GetInstrument(uint index) to class 'File' |
| 247 |
|
- added ReadAndLoop() method to class 'Sample' which is an extension to |
| 248 |
|
the normal Read() method to honor the sample's looping information |
| 249 |
|
while streaming from disk |
| 250 |
|
- changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and |
| 251 |
|
'eg2_ctrl_t': replaced this huge enumeration by a structure which |
| 252 |
|
reflects the MIDI controller number in case of an ordinary control |
| 253 |
|
change controller (this saves a huge switch-case block in the |
| 254 |
|
application of the library user) |
| 255 |
|
- renamed following attributes in class 'DimensionRegion': |
| 256 |
|
'AttenuationContol' -> 'AttenuationController', |
| 257 |
|
'InvertAttenuationControl' -> 'InvertAttenuationController', |
| 258 |
|
'AttenuationControlTreshold' -> 'AttenuationControllerThreshold' |
| 259 |
|
- minor fix in API documentation for method GetVelocityAttenuation() in |
| 260 |
|
class 'DimensionRegion' |
| 261 |
|
|
| 262 |
|
* src/RIFF.cpp, src/RIFF.h: |
| 263 |
|
- added additional API documentation |
| 264 |
|
- minor fix in Chunk::Read() method (only a minor efficiency issue) |
| 265 |
|
|
| 266 |
|
* src/gigdump.cpp: |
| 267 |
|
- added printout of samples' looping informations |
| 268 |
|
|
| 269 |
