Wed Nov 21 00:52:09 2007 UTC (16 years, 4 months ago) by senoner
File size: 18539 byte(s)
* win32 port, work in progress:
 - added ASIO low latency audio output driver
* MME MIDI input driver:
 - fixed number of PORTS to 1 as the win32 MME MIDI API
 allows to connect to only one MIDI port at time,

1 schoenebeck 1454 Version CVS HEAD (?)
2    
3     * packaging changes:
4     - added autoconf checks for pthread library
5     - added autoconf check for pthread bug found on certain NPTL-enabled
6     glibc versions (see Gentoo bug report #194076)
7    
8 persson 1455 * general changes:
9     - bugfix: the thread used by an editor plugin didn't die when the
10     editor closed
11 senoner 1479 - bugfix: Ringbuffer.h:
12     fill_write_space_with_null() did not zero out all the space
13     operator--() did not apply size_mask after decrementing the read_ptr
14 schoenebeck 1495 DEFAULT_WRAP_ELEMENTS set to 0 in order to avoid problems with
15 senoner 1479 the _NonVolatileReader functions.
16 senoner 1485 - bugfix: Stream.h: added a missing divide by BytesPerSample in GetWriteSpace()
17     since this function is currently only used in the stream's
18     qsort() compare function, it didn't trigger any bugs
19     Resampler.h, Synthesizer.h:
20     cubic interpolation now works in 24bit mode too
21     faster method to read 24bit words on little endian machines (x86):
22 schoenebeck 1495 replaced 3 byte reads + shifts with a 1 unaligned 32bit read and shift
23 persson 1455
24 senoner 1500 * AUDIO driver:
25     - added Windows ASIO low latency audio driver
26    
27 senoner 1485 * MIDI driver:
28 schoenebeck 1495 - added MME Windows MIDI driver
29 senoner 1485
30 schoenebeck 1471 * LSCP server:
31     - added support for Windows style path / filenames, however with
32     forward slash path separators instead of backslash
33     (i.e. "C:/foo/bar.gig")
34 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
35     apostrophes as well
36 schoenebeck 1471
37 schoenebeck 1424 Version 0.5.0 (15 October 2007)
38 schoenebeck 947
39 schoenebeck 1065 * packaging changes:
40 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
41     API header files anymore
42 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
43     the Doxygen API documentation (explicitly listed in Doxyfile.in)
44 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
45     capable to execute our autoconf environment, thus no need anymore
46     to maintain the compile time configuration file (osx/version.h) for
47     OSX manually (patch by Toshi Nagata)
48 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
49     parameters
50 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
51     C++ API header files, all implementation internal global definitions
52     are now in global_private.h
53     - atomic.h is not exposed to the C++ API anymore
54     - no need to include config.h anymore for using LS's API header files
55     - fixed warnings in API doc generation
56 schoenebeck 1065
57 schoenebeck 947 * general changes:
58     - replaced the old, confusing MIDI program change mechanism by a
59     flexible MIDI instrument mapper which allows to map arbitrary
60 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
61 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
62     loaded on the respective channel when such MIDI program change
63     messages arrive, beside that, each entry allows to define a life-time
64     strategy for the instrument, so the user can define whether the
65     instrument should i.e. be permanently loaded (to be able to switch
66     quickly among sounds) or i.e. loaded just on demand when the
67     respective program change arrives (to safe RAM space), as well as a
68     global volume factor for each entry, so the user can adjust the volume
69     dynamic of his mapped instrument collection without having to modify
70 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
71     MIDI instrument maps and assign each sampler channel individually
72     a certain map, so that i.e. separation of normal instruments and
73     drumkits is possible
74 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
75     MIDI instrument maps, MIDI instruments, FX sends, global volume.
76 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
77     due to a constant size RingBuffer FIFO which is now replaced by a
78     dynamic (unlimited) size std::list FIFO
79 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
80     output channels for being processed by external effect processors
81     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
82     controllers
83 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
84 iliev 1130 - Implemented new, improved notification system
85 schoenebeck 1149 - fixed compilation errors regarding OSX
86     (patch by Toshi Nagata)
87 iliev 1161 - implemented instruments database
88 iliev 1345 - added support for escape sequences to the instruments database
89 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
90     within the sampler's process (by using instrument editor plugins),
91     you'll notice the new "Registered instrument editors:" message on
92 schoenebeck 1407 startup, added a new LSCP command:
93     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
94 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
95     given sampler channel, the plugin path can be overridden at compile
96     time with ./configure --enable-plugin-dir=/some/dir
97 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
98     in the sampler's process to safely edit instruments while playing
99     without a crash (hopefully) by either suspending single regions
100     wherever possible or if unavoidable whole engine(s)
101 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
102     policy and priority on thread level, set a minimum stack size for
103     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
104     threads simply inherited properties of starting thread instead of
105     setting their own policy and priority
106 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
107     main process did not wait for the stack trace process to finish
108     its output
109 persson 1248 - fixed some minor memory leaks
110 schoenebeck 1259 - reenabled assembly features support, at the moment only for
111     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
112 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
113     register, to avoid relocations in the text segment at runtime)
114 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
115 schoenebeck 947
116     * MIDI driver:
117     - dispatch bank select (MSB and LSB) messages
118    
119 schoenebeck 1049 * audio driver:
120     - the ALSA audio output driver parameters now reflect the correct
121     parameter value ranges for the respective selected sound card
122     (patch by Till Wimmer, a bit fixed and extended)
123    
124 persson 951 * Gigasampler format engine:
125     - if a filter is used and EG2 finishes before EG1, let the voice
126     die when EG2 has finished (this fixes a problem with clicks and
127     voice starvation for some gigs)
128 persson 1038 - playback is no longer disabled during instrument loading
129     - all notes playing on a channel that changes its instrument keep
130     playing with the old instrument until they get a note off
131     command
132 persson 1039 - EG fix: a release value of zero could cause noises or crash
133 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
134 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
135     above max sustain level, which means that there is a decay phase
136     even if sustain is 100%
137 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
138     noises or crashes
139 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
140 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
141     supplied to the configure script (fixes #46)
142 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
143     instead of a fix value
144 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
145     127 (solo mode) only kill voices if the respective mode really
146     changed
147 persson 951
148 schoenebeck 1244 * LSCP server:
149     - fixed compile time error for old Bison versions
150     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
151 schoenebeck 1245 - parser now supports extended ASCII character set
152     (up to ASCII code 255, i.e. includes now umlauts and accents)
153     - filename arguments in LSCP commands now allow to use escape
154     sequences, that is directly literal as one of: \', \", \\, \n, \r,
155     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
156     code value like \xf2) (fixes bug #24)
157 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
158     least one of their text-based parameters (i.e. name, description):
159     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
160     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
161     "SET DB_INSTRUMENT_DIRECTORY NAME",
162     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
163     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
164     "FIND DB_INSTRUMENT_DIRECTORIES"
165 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
166     occured, the unexpected character and the actually expected, possible
167     character(s), the latter only if less than 5 possibilities)
168 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
169     settings
170 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
171     of strings were treated as being one string containing commas
172     (fixes #57)
173 schoenebeck 1244
174 iliev 959 * Bug fixes:
175     - fixed crash occurring on certain LSCP scripts (Bug 39)
176 persson 1038 - another thread safety fix for lscp "load engine" and "set
177     channel audio output device"
178 iliev 1283 - fixed a crash which occurs when reassigning the same engine
179     on a sampler channel with connected MIDI device
180 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
181     device connected to a sampler channel to number less then or equal
182     to the index of the port to which the sampler channel is connected.
183 iliev 1296 - The previous bindings were not been disconnected when altering
184     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
185     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
186 iliev 1297 - The active stream/voice count statistic was incorrect.
187 iliev 1298 - notification events were not been sent for some sampler
188     channel changes
189 iliev 1305 - added default min and max values to restrict the number of allowed
190     audio output channels and MIDI input ports
191 iliev 1306 - the connection to the PCM interface is now closed when destroying
192     an audio output device
193 schoenebeck 1332 - files with slash in their path or filename could not be loaded
194 iliev 959
195 schoenebeck 1221 * test cases:
196     - updated and fixed (haven't been touched in a while)
197    
198 schoenebeck 937 Version 0.4.0 (24 November 2006)
199 persson 696
200 schoenebeck 697 * packaging changes:
201 capela 868 - changed deprecated copyright attribute to license; added ldconfig
202     to post-(un)install steps; added devel package for liblinuxsampler;
203     to linuxsampler.spec (RPM)
204 schoenebeck 697 - install necessary development header files for allowing 3rd party
205     applications to link against liblinuxsampler
206     - liblinuxsampler's API documentation can be generated with 'make docs'
207     (Doxygen required)
208 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
209     implementation (currently either an integer math solution or a
210     di-harmonic approximation), automatic detection can be overriden
211     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
212     configure script argument though (mandatory for cross-compilation)
213 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
214     provided some on his own (as CXXFLAGS)
215 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
216     messages
217 schoenebeck 852 - added compile time options to allow disabling the various audio and
218     MIDI drivers
219 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
220     (patch by Ebrahim Mayat)
221 schoenebeck 697
222 persson 696 * Gigasampler format engine:
223 schoenebeck 738 - extensive synthesis optimization
224     (reimplementation of EGs and LFO(s), removed synthesis parameter
225     prerendering and the synthesis parameter matrix in general, splitting
226     each audio fragment into subfragments now where each subfragment uses
227 persson 830 constant pitch and filter coefficients. The volume coefficient is
228     linearly interpolated inside a subfragment, unless
229     --disable-interpolate-volume is set.)
230 persson 696 - fine tuning of the EG modulation parameters
231 persson 729 - improved filter cutoff calculation by adding support for the
232     following gig parameters: Cutoff freq (used when no cutoff
233     controller is defined), Control invert, Minimum cutoff, Velocity
234 persson 791 curve and Velocity range. The keyboard tracking now scales
235     cutoff frequency instead of resonance.
236 persson 877 - added support for gig parameter Resonance.
237 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
238 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
239     which can be overridden with --enable-global-attenuation
240 persson 783 - EG fixes: made the length of "attack hold" stage more
241     accurate. Release stage can now start before attack stage
242 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
243     time now has a minimal value to prevent clicks.
244 persson 799 - fixed pitch changes larger than one octave
245 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
246     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
247     all modes can be altered via standard GM messages, that is CC5 for
248     altering portamento time, CC65 for enabling / disabling portamento
249     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
250 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
251     parameter) and crossfade
252 persson 831 - added support for the "attenuation controller threshold" gig
253     parameter
254 persson 832 - added smoothing of volume changes caused by control change
255     messages
256 persson 865 - sample loop parameters are now taken from the DimensionRegion
257     instead of the wave chunk
258     - fixed keyswitching for v3 gigs with a number of keyswitch splits
259     not equal to a power of two
260 persson 877 - reimplementation of the filter algorithm. The new filter is more
261     accurate and supports all gig filter types, including bandreject
262     and lowpass turbo.
263 persson 903 - real support for 24 bit samples - samples are not truncated to
264     16 bits anymore
265     - support for aftertouch (channel pressure, not polyphonic
266     aftertouch)
267 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
268     amplifying from 0)
269 persson 696
270 schoenebeck 711 * LSCP server:
271     - fixed application exit on broken pipe error (fixes bug #20)
272 iliev 793 - fixed the notification messages delay due to lack of
273     network activity (fixes bug #26)
274 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
275     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
276 schoenebeck 711
277 schoenebeck 838 * audio driver:
278     - added aRts audio output driver (by no means RT safe)
279    
280 schoenebeck 775 * MIDI driver:
281     - fixed legacy sysex code which caused dispatching of MIDI SysEx
282     messages several times instead of once
283 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
284     for events (i.e. for offline rendering based MIDI drivers)
285 persson 922 - added checks for bad MIDI data
286 schoenebeck 775
287 schoenebeck 900 * linuxsampler application:
288     - show available sampler engine types on startup
289    
290 schoenebeck 705 * general changes:
291     - support for muting sampler channels and solo mode of the same, two new
292     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
293     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
294     introduced for this, the behavior is the same like on a mixer console
295 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
296     --enable-process-muted-channels which can be used to enable the
297     processing of muted channels.
298 iliev 777 - support for sostenuto pedal
299 iliev 779 - support for monitoring the total number of active voices
300 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
301     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
302 persson 835 - fixed some memory management errors
303 persson 841 - fixed some concurrency problems that could lead to crashes when
304     LSCP commands were executed
305 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
306     sampler channel (fixes bug #36)
307 schoenebeck 705
308 schoenebeck 692 Version 0.3.3 (15 July 2005)
309 schoenebeck 686
310     * packaging changes:
311     - fixed compilation with gcc 4.0
312    
313 schoenebeck 687 * Gigasampler format engine:
314     - LFO preprocessing was performed even though the respective LFO was
315     disabled by the instrument patch (minor efficiency fix)
316 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
317     for volume ramp downs in the same fragment (needed for current voice
318     stealing implementation) then simply inform the user with a warning
319     about possible click sounds and reduce the volume ramp down
320     appropriately instead of cancelling the audio device connection
321 schoenebeck 687
322 schoenebeck 677 Version 0.3.2 (24 June 2005)
323 schoenebeck 609
324     * packaging changes:
325     - updated autotools build files to compile on OS X
326     (conditional compilation of CoreMIDI and MidiShare drivers)
327 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
328     './configure --disable-asm' (definitely not recommended)
329 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
330     - require automake (>= 1.5) for 'make -f Makefile.cvs'
331     (due to 'dist-bzip2' automake option)
332 schoenebeck 649
333     * Gigasampler format engine:
334     - support for the gig parameters for "release velocity response" curves
335     - fine tuning of the EGADSR envelope
336     - volume of release triggered samples now depends on note-on velocity,
337     note length and gig parameter "release trigger decay" instead of
338     note-off velocity.
339 schoenebeck 663 - revised voice stealing
340     (fixes crash and endless loop caused by voice stealing)
341 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
342 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
343     instead of when the respective voice is actually launched
344     (fixes undefined behavior if stolen voices belonged to a key group -
345     this case was followed by a "killed voice survived" error message)
346 schoenebeck 669 - fixed minor issue with null/silence samples
347     (those stole voices even though they don't need a voice at all which
348     resulted in "voice stealing didn't work out" messages)
349 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
350     instrument or audio output device change
351 schoenebeck 654
352 schoenebeck 620 * LSCP server:
353 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
354 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
355 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
356 schoenebeck 609
357 schoenebeck 668 * linuxsampler application:
358     - added command line parameters --lscp-addr and --lscp-port to override
359     default IP address and port of LSCP server
360    
361 schoenebeck 579 Version 0.3.1 (24 May 2005)
362    
363     * initial release
