8 |
as this may hang on some systems |

Triggered rule is supported so far |
20 |
- bugfix: removed another iterator invalidation in DeleteSample |
21 |

sample start before trying to (re)load sample data from file (#82) |
23 |
- bugfix: EG3 depth parameter was not saved correctly |
24 |

25 |
bi-directional (a.k.a. 'pingpong') loop type (fixes #102) |
26 |
|
27 |
* src/RIFF.cpp, src/RIFF.h: |
28 |
- bugfix: saving to the same file after the file size had been |
29 |
increased made the file corrupt (#82) |
30 |
- bugfix: refuse Chunk::Read() in case chunk has just been added, that |
31 |
is not written physically yet (#82) |
32 |
- bugfix: saving to the same file after the file size had been |
33 |
decreased sometimes also made the file corrupt! |
34 |

35 |
length files, now throws a RIFF::Exception instead (fixes bug #121) |
36 |

37 |
of derived class RIFF::File, which is bad, and caused crashes |
38 |
when using Visual C++ |
39 |
- bugfix: files that contain zero length RIFF lists were not read |
40 |
correctly (fixes #127) (bug was introduced 2009-03-13) |

82 |
instrument constructors |
83 |

97 |
einf contains file statistics) |
98 |
- write support: DLSID is now generated on the file and the |
99 |
instruments |
100 |
- write support: improved the default values for dimension region |
101 |
parameters |
102 |
- more write support fixes: crossfade parameters were not saved, |
103 |
v3 dimension limits were not correctly initialized and saved |
104 |

- write support: 24 bit samples can now be written |
107 |
- write support: version 3 is now the default for new files |
108 |

where incorrectly saved due to an operator precedence mistake |
112 |
- DeleteSample now removes all references to the deleted sample |
113 |

117 |
parent Region |
118 |

that is File::DeleteGroup() now removes not just the group, but also |
145 |
all the samples that belong to that group |
146 |

155 |
the region's first dimension region's sample (avoids an exception |
156 |
when trying to save a new instrument) |
157 |
- fixed AddDimension() method which did not fill out all mandatory |
158 |
dimension definition fields |
159 |

File::Save() was called |
169 |
- added List::MoveSubChunk method |
170 |

instead of the wave chunk |
183 |
- keyswitching dimension is changed from split type "normal" to |

placing the new data in the chunk's write buffer and perform the |
236 |
resize and write operations in one rush |
237 |
|
238 |

295 |
- added some file format compatibility checks |
296 |
- fixed vcf_type_lowpassturbo value (vcf_type_lowpassturbo was actually |

* packaging changes: |
348 |
- renamed 'libgig.pc.in' -> 'gig.pc.in' and renamed pkg-config lib name |

389 |
|
390 |
Version 0.7.0 (3 May 2004) |
391 |
|
392 |
* general changes: |
393 |
- various big endian specific corrections |
394 |
(successfully tested now on PPC) |
395 |
- minor adjustments to avoid compile errors on some systems |
396 |
(using now pow() instead of powl() and --pedantic g++ compiler switch) |
397 |
- libtoolized the library |
398 |
- added man pages for the command line tools |
399 |
(gigextract, gigdump, dlsdump, rifftree) |
400 |
|
401 |
* src/gig.cpp, src/gig.h: |
402 |
- fixed bug in decompression algorithm which caused it not to detect |
403 |
the end of a stream |
404 |
- added method GetVelocityAttenuation() to class 'DimensionRegion' which |
405 |
takes the MIDI key velocity value as an argument and returns the |
406 |
appropriate volume factor (0.0 ... 1.0) for the sample to be played |
407 |
back, the velocity curve transformation functions used for this are |
408 |
only an approximation so far |
409 |
- fixed class attributes 'Sample::LoopStart', 'Sample::LoopEnd' and |
410 |
'Sample::LoopSize' which reflected wrong values |
411 |
- class attributes 'Sample::LoopStart' and 'Sample::LoopEnd' are now |
412 |
measured in sample points instead of byte offset |
413 |
- renamed misleading attribute name 'Sample::MIDIPitchFraction' to |
414 |
'Sample::FineTune' |
415 |
- added class attribute 'Sample::LoopSize' |
416 |
- added method GetInstrument(uint index) to class 'File' |
417 |
- added ReadAndLoop() method to class 'Sample' which is an extension to |
418 |
the normal Read() method to honor the sample's looping information |
419 |
while streaming from disk |
420 |
- changed interface for 'attenuation_ctrl_t', 'eg1_ctrl_t' and |
421 |
'eg2_ctrl_t': replaced this huge enumeration by a structure which |
422 |
reflects the MIDI controller number in case of an ordinary control |
423 |
change controller (this saves a huge switch-case block in the |
424 |
application of the library user) |
425 |
- renamed following attributes in class 'DimensionRegion': |
426 |
'AttenuationContol' -> 'AttenuationController', |
427 |
'InvertAttenuationControl' -> 'InvertAttenuationController', |
