| 5 |
- fixes for building with Visual C++ |
| 6 |
|
| 7 |
* src/gig.cpp, src/gig.h: |
| 8 |
- added partial support for MIDI rules, only the Controller |
| 9 |
Triggered rule is supported so far |
| 10 |
- bugfix: removed another iterator invalidation in DeleteSample |
| 11 |
- bugfix in Sample::LoadSampleData*(): reset sample read position to |
| 12 |
sample start before trying to (re)load sample data from file (#82) |
| 13 |
- bugfix: EG3 depth parameter was not saved correctly |
| 14 |
- fixed crash which occured when streaming a gig sample with |
| 15 |
bi-directional (a.k.a. 'pingpong') loop type (fixes #102) |
| 16 |
|
| 17 |
* src/RIFF.cpp, src/RIFF.h: |
| 18 |
- bugfix: saving to the same file after the file size had been |
| 19 |
increased made the file corrupt (#82) |
| 20 |
- bugfix: refuse Chunk::Read() in case chunk has just been added, that |
| 21 |
is not written physically yet (#82) |
| 22 |
- bugfix: saving to the same file after the file size had been |
| 23 |
decreased sometimes also made the file corrupt! |
| 24 |
- bugfix: undefined behavior (e.g. endless loop) when opening zero |
| 25 |
length files, now throws a RIFF::Exception instead (fixes bug #121) |
| 26 |
- bugfix: destructor for base class RIFF::Chunk accessed members |
| 27 |
of derived class RIFF::File, which is bad, and caused crashes |
| 28 |
when using Visual C++ |
| 29 |
- bugfix: files that contain zero length RIFF lists were not read |
| 30 |
correctly (fixes #127) (bug was introduced 2009-03-13) |
| 31 |
|
| 32 |
Version 3.2.1 (5 Dec 2007) |
| 33 |
|
| 34 |
* src/RIFF.cpp, src/RIFF.h: |
| 35 |
- avoid Windows to perform unnecessary file stream caching which would |
| 36 |
decrease disk streaming performance on Windows systems otherwise |
| 37 |
|
| 38 |
* src/gig.cpp, src/gig.h: |
| 39 |
- added File::SetAutoLoad() and File::GetAutoLoad() for allowing |
| 40 |
applications to retrieve very superficial informations like amount of |
| 41 |
instruments and their names in a very fast way |
| 42 |
|
| 43 |

| 67 |
happened when gig::Group informations were accessed before |
| 68 |

| 72 |
instrument constructors |
| 73 |
- clear unused fields when saving samples and regions |
| 74 |

couldn't be saved, group name list chunk was placed wrong, |
| 77 |
dimension region chunks also placed wrong |
| 78 |

| 86 |
updated when a file is saved (3crc contains sample checksums, |
| 87 |
einf contains file statistics) |
| 88 |
- write support: DLSID is now generated on the file and the |
| 89 |
instruments |
| 90 |
- write support: improved the default values for dimension region |
| 91 |

| 94 |
when dimensions were added or deleted, v3 wave pool offsets were |
| 95 |
not saved correctly |
| 96 |
- write support: 24 bit samples can now be written |
| 97 |
- write support: version 3 is now the default for new files |
| 98 |
- more write support fixes: the 3ewg chunk is now bigger for v3, |
| 99 |
dimension regions without mapped samples are now allowed, 3gnl |
| 100 |
list in v3 files now always has 128 entries, several parameters |
| 101 |
where incorrectly saved due to an operator precedence mistake |
| 102 |
- DeleteSample now removes all references to the deleted sample |
| 103 |
- AddDimension now copies all parameters from existing dimension |
| 104 |
regions and also makes sure that the samplechannel dimension is |
| 105 |
placed first in the list of dimensions. |
| 106 |
- added method GetParent() to class 'DimensionRegion', which returns its |
| 107 |
parent Region |
| 108 |
- fixed Instrument::UpdateRegionKeyTable() method which did not reset |
| 109 |
unused areas |
| 110 |
- added various setter methods to DimensionRegion class which take care |
| 111 |
of updating lookup tables / caches. |
| 112 |
|
| 113 |
* src/RIFF.cpp, src/RIFF.h: |
| 114 |
- added File::SetByteOrder method |
| 115 |

| 130 |
velocity (gig v3 feature) |
| 131 |
- added "smart midi" and "round robin keyboard" dimensions |
| 132 |
- added new method File::DeleteGroupOnly() which only deletes the given |
| 133 |
group but moves all its members to another group, the other method, |
| 134 |
that is File::DeleteGroup() now removes not just the group, but also |
| 135 |
all the samples that belong to that group |
| 136 |
- fixed crash which occured on interfering File::DeleteSample() and |
| 137 |
File::GetNextSample() calls (due to iterator invalidation) |

| 143 |
when used from Instrument::AddRegion |
| 144 |
- when saving, override the gig::Regions sample reference simply by |
| 145 |
the region's first dimension region's sample (avoids an exception |
| 146 |
when trying to save a new instrument) |
| 147 |

| 148 |
dimension definition fields |
| 149 |

* src/RIFF.cpp, src/RIFF.h: |
| 156 |

| 157 |
resized chunks, leading to a "zero size chunk" exception when |
| 158 |
File::Save() was called |
| 159 |
- added List::MoveSubChunk method |
| 160 |
|
| 161 |

placing the new data in the chunk's write buffer and perform the |
| 226 |
resize and write operations in one rush |
| 227 |
|
| 228 |

| 244 |
the extension files are read automatically when the samples are |

| 285 |
- added some file format compatibility checks |
| 286 |
- fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually |

| 290 |
endian systems was interchanged) |
| 291 |

* packaging changes: |
| 338 |

| 371 |
|
| 372 |
* packaging changes: |
| 373 |

| 380 |
Version 0.7.0 (3 May 2004) |
| 381 |
|
| 382 |
* general changes: |
| 383 |
- various big endian specific corrections |
| 384 |
(successfully tested now on PPC) |
| 385 |
- minor adjustments to avoid compile errors on some systems |
| 386 |
(using now pow() instead of powl() and --pedantic g++ compiler switch) |
| 387 |
- libtoolized the library |
| 388 |
- added man pages for the command line tools |
| 389 |

* src/gig.cpp, src/gig.h: |
| 392 |
- fixed bug in decompression algorithm which caused it not to detect |
| 393 |
the end of a stream |
| 394 |
- added method GetVelocityAttenuation() to class 'DimensionRegion' which |
| 395 |
takes the MIDI key velocity value as an argument and returns the |
| 396 |
appropriate volume factor (0.0 ... 1.0) for the sample to be played |
| 397 |
back, the velocity curve transformation functions used for this are |
| 398 |
only an approximation so far |
| 399 |
- fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and |
| 400 |
'Sample::LoopSize' which reflected wrong values |
| 401 |
- class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now |
| 402 |
measured in sample points instead of byte offset |
| 403 |
- renamed misleading attribute name 'Sample::MIDIPitchFraction' to |
| 404 |
'Sample::FineTune' |
| 405 |
- added class attribute 'Sample::LoopSize' |
| 406 |
- added method GetInstrument(uint index) to class 'File' |
| 407 |
- added ReadAndLoop() method to class 'Sample' which is an extension to |
| 408 |
the normal Read() method to honor the sample's looping information |
| 409 |
while streaming from disk |
| 410 |
- changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and |
| 411 |
'eg2_ctrl_t': replaced this huge enumeration by a structure which |
| 412 |
reflects the MIDI controller number in case of an ordinary control |
| 413 |
change controller (this saves a huge switch-case block in the |
| 414 |
application of the library user) |
| 415 |
- renamed following attributes in class 'DimensionRegion': |
| 416 |
'AttenuationContol' -> 'AttenuationController', |
| 417 |
'InvertAttenuationControl' -> 'InvertAttenuationController', |
| 418 |
'AttenuationControlTreshold' -> 'AttenuationControllerThreshold' |
| 419 |
- minor fix in API documentation for method GetVelocityAttenuation() in |
| 420 |
class 'DimensionRegion' |
| 421 |
|
| 422 |
* src/RIFF.cpp, src/RIFF.h: |
