File size: 18667 byte(s)
* win32 port, work in progress: added autoconf checks for Windows
 - win32 additions in linuxsampler.cpp

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 senoner 1502 - added autoconf checks for MS Windows
8 schoenebeck 1454
9 persson 1455 * general changes:
10     - bugfix: the thread used by an editor plugin didn't die when the
11     editor closed
12 senoner 1479 - bugfix: Ringbuffer.h:
13     fill_write_space_with_null() did not zero out all the space
14     operator--() did not apply size_mask after decrementing the read_ptr
15 schoenebeck 1495 DEFAULT_WRAP_ELEMENTS set to 0 in order to avoid problems with
16 senoner 1479 the _NonVolatileReader functions.
17 senoner 1485 - bugfix: Stream.h: added a missing divide by BytesPerSample in GetWriteSpace()
18     since this function is currently only used in the stream's
19     qsort() compare function, it didn't trigger any bugs
20     Resampler.h, Synthesizer.h:
21     cubic interpolation now works in 24bit mode too
22     faster method to read 24bit words on little endian machines (x86):
23 schoenebeck 1495 replaced 3 byte reads + shifts with a 1 unaligned 32bit read and shift
24 senoner 1502 Experimental support for MS Windows (MIDI input via MME, AUDIO output via ASIO)
25 persson 1455
26 senoner 1500 * AUDIO driver:
27     - added Windows ASIO low latency audio driver
28    
29 senoner 1485 * MIDI driver:
30 schoenebeck 1495 - added MME Windows MIDI driver
31 senoner 1485
32 schoenebeck 1471 * LSCP server:
33     - added support for Windows style path / filenames, however with
34     forward slash path separators instead of backslash
35     (i.e. "C:/foo/bar.gig")
36 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
37     apostrophes as well
38 schoenebeck 1471
39 schoenebeck 1424 Version 0.5.0 (15 October 2007)
40 schoenebeck 947
41 schoenebeck 1065 * packaging changes:
42 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
43     API header files anymore
44 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
45     the Doxygen API documentation (explicitly listed in Doxyfile.in)
46 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
47     capable to execute our autoconf environment, thus no need anymore
48     to maintain the compile time configuration file (osx/version.h) for
49     OSX manually (patch by Toshi Nagata)
50 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
51     parameters
52 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
53     C++ API header files, all implementation internal global definitions
54     are now in global_private.h
55     - atomic.h is not exposed to the C++ API anymore
56     - no need to include config.h anymore for using LS's API header files
57     - fixed warnings in API doc generation
58 schoenebeck 1065
59 schoenebeck 947 * general changes:
60     - replaced the old, confusing MIDI program change mechanism by a
61     flexible MIDI instrument mapper which allows to map arbitrary
62 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
63 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
64     loaded on the respective channel when such MIDI program change
65     messages arrive, beside that, each entry allows to define a life-time
66     strategy for the instrument, so the user can define whether the
67     instrument should i.e. be permanently loaded (to be able to switch
68     quickly among sounds) or i.e. loaded just on demand when the
69     respective program change arrives (to safe RAM space), as well as a
70     global volume factor for each entry, so the user can adjust the volume
71     dynamic of his mapped instrument collection without having to modify
72 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
73     MIDI instrument maps and assign each sampler channel individually
74     a certain map, so that i.e. separation of normal instruments and
75     drumkits is possible
76 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
77     MIDI instrument maps, MIDI instruments, FX sends, global volume.
78 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
79     due to a constant size RingBuffer FIFO which is now replaced by a
80     dynamic (unlimited) size std::list FIFO
81 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
82     output channels for being processed by external effect processors
83     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
84     controllers
85 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
86 iliev 1130 - Implemented new, improved notification system
87 schoenebeck 1149 - fixed compilation errors regarding OSX
88     (patch by Toshi Nagata)
89 iliev 1161 - implemented instruments database
90 iliev 1345 - added support for escape sequences to the instruments database
91 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
92     within the sampler's process (by using instrument editor plugins),
93     you'll notice the new "Registered instrument editors:" message on
94 schoenebeck 1407 startup, added a new LSCP command:
95     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
96 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
97     given sampler channel, the plugin path can be overridden at compile
98     time with ./configure --enable-plugin-dir=/some/dir
99 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
100     in the sampler's process to safely edit instruments while playing
101     without a crash (hopefully) by either suspending single regions
102     wherever possible or if unavoidable whole engine(s)
103 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
104     policy and priority on thread level, set a minimum stack size for
105     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
106     threads simply inherited properties of starting thread instead of
107     setting their own policy and priority
108 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
109     main process did not wait for the stack trace process to finish
110     its output
111 persson 1248 - fixed some minor memory leaks
112 schoenebeck 1259 - reenabled assembly features support, at the moment only for
113     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
114 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
115     register, to avoid relocations in the text segment at runtime)
116 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
117 schoenebeck 947
118     * MIDI driver:
119     - dispatch bank select (MSB and LSB) messages
120    
121 schoenebeck 1049 * audio driver:
122     - the ALSA audio output driver parameters now reflect the correct
123     parameter value ranges for the respective selected sound card
124     (patch by Till Wimmer, a bit fixed and extended)
125    
126 persson 951 * Gigasampler format engine:
127     - if a filter is used and EG2 finishes before EG1, let the voice
128     die when EG2 has finished (this fixes a problem with clicks and
129     voice starvation for some gigs)
130 persson 1038 - playback is no longer disabled during instrument loading
131     - all notes playing on a channel that changes its instrument keep
132     playing with the old instrument until they get a note off
133     command
134 persson 1039 - EG fix: a release value of zero could cause noises or crash
135 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
136 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
137     above max sustain level, which means that there is a decay phase
138     even if sustain is 100%
139 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
140     noises or crashes
141 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
142 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
143     supplied to the configure script (fixes #46)
144 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
145     instead of a fix value
146 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
147     127 (solo mode) only kill voices if the respective mode really
148     changed
149 persson 951
150 schoenebeck 1244 * LSCP server:
151     - fixed compile time error for old Bison versions
152     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
153 schoenebeck 1245 - parser now supports extended ASCII character set
154     (up to ASCII code 255, i.e. includes now umlauts and accents)
155     - filename arguments in LSCP commands now allow to use escape
156     sequences, that is directly literal as one of: \', \", \\, \n, \r,
157     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
158     code value like \xf2) (fixes bug #24)
159 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
160     least one of their text-based parameters (i.e. name, description):
161     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
162     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
163     "SET DB_INSTRUMENT_DIRECTORY NAME",
164     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
165     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
166     "FIND DB_INSTRUMENT_DIRECTORIES"
167 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
168     occured, the unexpected character and the actually expected, possible
169     character(s), the latter only if less than 5 possibilities)
170 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
171     settings
172 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
173     of strings were treated as being one string containing commas
174     (fixes #57)
175 schoenebeck 1244
176 iliev 959 * Bug fixes:
177     - fixed crash occurring on certain LSCP scripts (Bug 39)
178 persson 1038 - another thread safety fix for lscp "load engine" and "set
179     channel audio output device"
180 iliev 1283 - fixed a crash which occurs when reassigning the same engine
181     on a sampler channel with connected MIDI device
182 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
183     device connected to a sampler channel to number less then or equal
184     to the index of the port to which the sampler channel is connected.
185 iliev 1296 - The previous bindings were not been disconnected when altering
186     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
187     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
188 iliev 1297 - The active stream/voice count statistic was incorrect.
189 iliev 1298 - notification events were not been sent for some sampler
190     channel changes
191 iliev 1305 - added default min and max values to restrict the number of allowed
192     audio output channels and MIDI input ports
193 iliev 1306 - the connection to the PCM interface is now closed when destroying
194     an audio output device
195 schoenebeck 1332 - files with slash in their path or filename could not be loaded
196 iliev 959
197 schoenebeck 1221 * test cases:
198     - updated and fixed (haven't been touched in a while)
199    
200 schoenebeck 937 Version 0.4.0 (24 November 2006)
201 persson 696
202 schoenebeck 697 * packaging changes:
203 capela 868 - changed deprecated copyright attribute to license; added ldconfig
204     to post-(un)install steps; added devel package for liblinuxsampler;
205     to linuxsampler.spec (RPM)
206 schoenebeck 697 - install necessary development header files for allowing 3rd party
207     applications to link against liblinuxsampler
208     - liblinuxsampler's API documentation can be generated with 'make docs'
209     (Doxygen required)
210 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
211     implementation (currently either an integer math solution or a
212     di-harmonic approximation), automatic detection can be overriden
213     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
214     configure script argument though (mandatory for cross-compilation)
215 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
216     provided some on his own (as CXXFLAGS)
217 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
218     messages
219 schoenebeck 852 - added compile time options to allow disabling the various audio and
220     MIDI drivers
221 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
222     (patch by Ebrahim Mayat)
223 schoenebeck 697
224 persson 696 * Gigasampler format engine:
225 schoenebeck 738 - extensive synthesis optimization
226     (reimplementation of EGs and LFO(s), removed synthesis parameter
227     prerendering and the synthesis parameter matrix in general, splitting
228     each audio fragment into subfragments now where each subfragment uses
229 persson 830 constant pitch and filter coefficients. The volume coefficient is
230     linearly interpolated inside a subfragment, unless
231     --disable-interpolate-volume is set.)
232 persson 696 - fine tuning of the EG modulation parameters
233 persson 729 - improved filter cutoff calculation by adding support for the
234     following gig parameters: Cutoff freq (used when no cutoff
235     controller is defined), Control invert, Minimum cutoff, Velocity
236 persson 791 curve and Velocity range. The keyboard tracking now scales
237     cutoff frequency instead of resonance.
238 persson 877 - added support for gig parameter Resonance.
239 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
240 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
241     which can be overridden with --enable-global-attenuation
242 persson 783 - EG fixes: made the length of "attack hold" stage more
243     accurate. Release stage can now start before attack stage
244 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
245     time now has a minimal value to prevent clicks.
246 persson 799 - fixed pitch changes larger than one octave
247 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
248     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
249     all modes can be altered via standard GM messages, that is CC5 for
250     altering portamento time, CC65 for enabling / disabling portamento
251     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
252 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
253     parameter) and crossfade
254 persson 831 - added support for the "attenuation controller threshold" gig
255     parameter
256 persson 832 - added smoothing of volume changes caused by control change
257     messages
258 persson 865 - sample loop parameters are now taken from the DimensionRegion
259     instead of the wave chunk
260     - fixed keyswitching for v3 gigs with a number of keyswitch splits
261     not equal to a power of two
262 persson 877 - reimplementation of the filter algorithm. The new filter is more
263     accurate and supports all gig filter types, including bandreject
264     and lowpass turbo.
265 persson 903 - real support for 24 bit samples - samples are not truncated to
266     16 bits anymore
267     - support for aftertouch (channel pressure, not polyphonic
268     aftertouch)
269 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
270     amplifying from 0)
271 persson 696
272 schoenebeck 711 * LSCP server:
273     - fixed application exit on broken pipe error (fixes bug #20)
274 iliev 793 - fixed the notification messages delay due to lack of
275     network activity (fixes bug #26)
276 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
277     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
278 schoenebeck 711
279 schoenebeck 838 * audio driver:
280     - added aRts audio output driver (by no means RT safe)
281    
282 schoenebeck 775 * MIDI driver:
283     - fixed legacy sysex code which caused dispatching of MIDI SysEx
284     messages several times instead of once
285 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
286     for events (i.e. for offline rendering based MIDI drivers)
287 persson 922 - added checks for bad MIDI data
288 schoenebeck 775
289 schoenebeck 900 * linuxsampler application:
290     - show available sampler engine types on startup
291    
292 schoenebeck 705 * general changes:
293     - support for muting sampler channels and solo mode of the same, two new
294     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
295     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
296     introduced for this, the behavior is the same like on a mixer console
297 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
298     --enable-process-muted-channels which can be used to enable the
299     processing of muted channels.
300 iliev 777 - support for sostenuto pedal
301 iliev 779 - support for monitoring the total number of active voices
302 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
303     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
304 persson 835 - fixed some memory management errors
305 persson 841 - fixed some concurrency problems that could lead to crashes when
306     LSCP commands were executed
307 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
308     sampler channel (fixes bug #36)
309 schoenebeck 705
310 schoenebeck 692 Version 0.3.3 (15 July 2005)
311 schoenebeck 686
312     * packaging changes:
313     - fixed compilation with gcc 4.0
314    
315 schoenebeck 687 * Gigasampler format engine:
316     - LFO preprocessing was performed even though the respective LFO was
317     disabled by the instrument patch (minor efficiency fix)
318 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
319     for volume ramp downs in the same fragment (needed for current voice
320     stealing implementation) then simply inform the user with a warning
321     about possible click sounds and reduce the volume ramp down
322     appropriately instead of cancelling the audio device connection
323 schoenebeck 687
324 schoenebeck 677 Version 0.3.2 (24 June 2005)
325 schoenebeck 609
326     * packaging changes:
327     - updated autotools build files to compile on OS X
328     (conditional compilation of CoreMIDI and MidiShare drivers)
329 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
330     './configure --disable-asm' (definitely not recommended)
331 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
332     - require automake (>= 1.5) for 'make -f Makefile.cvs'
333     (due to 'dist-bzip2' automake option)
334 schoenebeck 649
335     * Gigasampler format engine:
336     - support for the gig parameters for "release velocity response" curves
337     - fine tuning of the EGADSR envelope
338     - volume of release triggered samples now depends on note-on velocity,
339     note length and gig parameter "release trigger decay" instead of
340     note-off velocity.
341 schoenebeck 663 - revised voice stealing
342     (fixes crash and endless loop caused by voice stealing)
343 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
344 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
345     instead of when the respective voice is actually launched
346     (fixes undefined behavior if stolen voices belonged to a key group -
347     this case was followed by a "killed voice survived" error message)
348 schoenebeck 669 - fixed minor issue with null/silence samples
349     (those stole voices even though they don't need a voice at all which
350     resulted in "voice stealing didn't work out" messages)
351 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
352     instrument or audio output device change
353 schoenebeck 654
354 schoenebeck 620 * LSCP server:
355 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
356 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
357 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
358 schoenebeck 609
359 schoenebeck 668 * linuxsampler application:
360     - added command line parameters --lscp-addr and --lscp-port to override
361     default IP address and port of LSCP server
362    
363 schoenebeck 579 Version 0.3.1 (24 May 2005)
364    
365     * initial release
