* fixed endless loop which occured when loading an instrument editor
  plugin DLL on Windows systems failed (note: completely untested yet :) )

1 schoenebeck 1599 Version CVS HEAD (?)
2    
3 schoenebeck 1601 * general changes:
4     - bugfix: on some POSIX systems instrument editor plugins refused to
5     load as we used a non-portable Linux specific struct field
6     (fixes bug #70, patch by Ronald Baljeu)
7 schoenebeck 1602 - fixed endless loop which occured when loading an instrument editor
8     plugin DLL on Windows systems failed
9 schoenebeck 1601
10 schoenebeck 1599 * audio driver:
11     - removed the nonsense audio channel constraint (which was hard coded to
12     max. 100 audio channels) for most audio drivers
13    
14 schoenebeck 1560 Version 0.5.1 (6 December 2007)
15 schoenebeck 1454
16     * packaging changes:
17     - added autoconf checks for pthread library
18     - added autoconf check for pthread bug found on certain NPTL-enabled
19     glibc versions (see Gentoo bug report #194076)
20 senoner 1502 - added autoconf checks for MS Windows
21 schoenebeck 1454
22 persson 1455 * general changes:
23     - bugfix: the thread used by an editor plugin didn't die when the
24     editor closed
25 persson 1534 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
26     out all the space. operator--() did not apply size_mask after
27     decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
28     order to avoid problems with the _NonVolatileReader functions.
29     - bugfix: Stream.h: added a missing divide by BytesPerSample in
30     GetWriteSpace(). Since this function is currently only used in
31     the stream's qsort() compare function, it didn't trigger any
32     bugs.
33     - Resampler.h, Synthesizer.h: cubic interpolation now works in
34     24bit mode too. Faster method to read 24bit words on little
35     endian machines (x86): replaced 3 byte reads + shifts with a 1
36     unaligned 32bit read and shift
37     - experimental support for MS Windows (MIDI input via MME, AUDIO
38     output via ASIO)
39     - made handling of SIGINT signal (Ctrl-C) a bit more robust
40 iliev 1541 - support for monitoring the total number of active disk streams
41     (new LSCP commands: GET TOTAL_STREAM_COUNT,
42     SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
43 persson 1455
44 senoner 1500 * AUDIO driver:
45 persson 1534 - added Windows ASIO low latency audio driver
46 senoner 1500
47 senoner 1485 * MIDI driver:
48 schoenebeck 1495 - added MME Windows MIDI driver
49 senoner 1485
50 schoenebeck 1471 * LSCP server:
51     - added support for Windows style path / filenames, however with
52     forward slash path separators instead of backslash
53     (i.e. "C:/foo/bar.gig")
54 schoenebeck 1495 - allow naughty liblscp to send non-string device parameters within
55     apostrophes as well
56 schoenebeck 1525 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
57     "LIST FILE INSTRUMENTS <file>" and
58     "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
59     about an arbitrary instrument file on the system where the sampler is
60     running on
61 schoenebeck 1471
62 schoenebeck 1424 Version 0.5.0 (15 October 2007)
63 schoenebeck 947
64 schoenebeck 1065 * packaging changes:
65 schoenebeck 1212 - config.h is not going to be installed along with liblinuxsampler's
66     API header files anymore
67 schoenebeck 1065 - only the API relevant header (and source) files will be exported to
68     the Doxygen API documentation (explicitly listed in Doxyfile.in)
69 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
70     capable to execute our autoconf environment, thus no need anymore
71     to maintain the compile time configuration file (osx/version.h) for
72     OSX manually (patch by Toshi Nagata)
73 schoenebeck 1360 - fixed buggy boolean --enable-foo / --disable-foo configure script
74     parameters
75 schoenebeck 1424 - global.h now only covers global definitions that are needed for the
76     C++ API header files, all implementation internal global definitions
77     are now in global_private.h
78     - atomic.h is not exposed to the C++ API anymore
79     - no need to include config.h anymore for using LS's API header files
80     - fixed warnings in API doc generation
81 schoenebeck 1065
82 schoenebeck 947 * general changes:
83     - replaced the old, confusing MIDI program change mechanism by a
84     flexible MIDI instrument mapper which allows to map arbitrary
85 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
86 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
87     loaded on the respective channel when such MIDI program change
88     messages arrive, beside that, each entry allows to define a life-time
89     strategy for the instrument, so the user can define whether the
90     instrument should i.e. be permanently loaded (to be able to switch
91     quickly among sounds) or i.e. loaded just on demand when the
92     respective program change arrives (to safe RAM space), as well as a
93     global volume factor for each entry, so the user can adjust the volume
94     dynamic of his mapped instrument collection without having to modify
95 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
96     MIDI instrument maps and assign each sampler channel individually
97     a certain map, so that i.e. separation of normal instruments and
98     drumkits is possible
99 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
100     MIDI instrument maps, MIDI instruments, FX sends, global volume.
101 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
102     due to a constant size RingBuffer FIFO which is now replaced by a
103     dynamic (unlimited) size std::list FIFO
104 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
105     output channels for being processed by external effect processors
106     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
107     controllers
108 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
109 iliev 1130 - Implemented new, improved notification system
110 schoenebeck 1149 - fixed compilation errors regarding OSX
111     (patch by Toshi Nagata)
112 iliev 1161 - implemented instruments database
113 iliev 1345 - added support for escape sequences to the instruments database
114 schoenebeck 1212 - added highly experimental support for on-the-fly instrument editing
115     within the sampler's process (by using instrument editor plugins),
116     you'll notice the new "Registered instrument editors:" message on
117 schoenebeck 1407 startup, added a new LSCP command:
118     "EDIT CHANNEL INSTRUMENT <sampler-channel>"
119 schoenebeck 1212 to spawn a matching instrument editor for the instrument on the
120     given sampler channel, the plugin path can be overridden at compile
121     time with ./configure --enable-plugin-dir=/some/dir
122 schoenebeck 1321 - added experimental code for synchronizing instrument editors hosted
123     in the sampler's process to safely edit instruments while playing
124     without a crash (hopefully) by either suspending single regions
125     wherever possible or if unavoidable whole engine(s)
126 schoenebeck 1221 - fixed several issues in fundamental "Thread" class: set scheduling
127     policy and priority on thread level, set a minimum stack size for
128     thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
129     threads simply inherited properties of starting thread instead of
130     setting their own policy and priority
131 schoenebeck 1233 - minor fix in our automatic stack trace mechanism on crashes, the
132     main process did not wait for the stack trace process to finish
133     its output
134 persson 1248 - fixed some minor memory leaks
135 schoenebeck 1259 - reenabled assembly features support, at the moment only for
136     enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
137 schoenebeck 1314 - minor assembly fix in x86 features detection (don't use the PIC
138     register, to avoid relocations in the text segment at runtime)
139 schoenebeck 1424 - POSIX callback functions of Thread.h are hidden
140 schoenebeck 947
141     * MIDI driver:
142     - dispatch bank select (MSB and LSB) messages
143    
144 schoenebeck 1049 * audio driver:
145     - the ALSA audio output driver parameters now reflect the correct
146     parameter value ranges for the respective selected sound card
147     (patch by Till Wimmer, a bit fixed and extended)
148    
149 persson 951 * Gigasampler format engine:
150     - if a filter is used and EG2 finishes before EG1, let the voice
151     die when EG2 has finished (this fixes a problem with clicks and
152     voice starvation for some gigs)
153 persson 1038 - playback is no longer disabled during instrument loading
154     - all notes playing on a channel that changes its instrument keep
155     playing with the old instrument until they get a note off
156     command
157 persson 1039 - EG fix: a release value of zero could cause noises or crash
158 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
159 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
160     above max sustain level, which means that there is a decay phase
161     even if sustain is 100%
162 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
163     noises or crashes
164 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
165 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
166     supplied to the configure script (fixes #46)
167 schoenebeck 1321 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
168     instead of a fix value
169 schoenebeck 1348 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
170     127 (solo mode) only kill voices if the respective mode really
171     changed
172 persson 951
173 schoenebeck 1244 * LSCP server:
174     - fixed compile time error for old Bison versions
175     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
176 schoenebeck 1245 - parser now supports extended ASCII character set
177     (up to ASCII code 255, i.e. includes now umlauts and accents)
178     - filename arguments in LSCP commands now allow to use escape
179     sequences, that is directly literal as one of: \', \", \\, \n, \r,
180     \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
181     code value like \xf2) (fixes bug #24)
182 schoenebeck 1389 - the following LSCP commands now also support escape sequences for at
183     least one of their text-based parameters (i.e. name, description):
184     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
185     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
186     "SET DB_INSTRUMENT_DIRECTORY NAME",
187     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
188     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
189     "FIND DB_INSTRUMENT_DIRECTORIES"
190 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
191     occured, the unexpected character and the actually expected, possible
192     character(s), the latter only if less than 5 possibilities)
193 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
194     settings
195 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
196     of strings were treated as being one string containing commas
197     (fixes #57)
198 schoenebeck 1244
199 iliev 959 * Bug fixes:
200     - fixed crash occurring on certain LSCP scripts (Bug 39)
201 persson 1038 - another thread safety fix for lscp "load engine" and "set
202     channel audio output device"
203 iliev 1283 - fixed a crash which occurs when reassigning the same engine
204     on a sampler channel with connected MIDI device
205 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
206     device connected to a sampler channel to number less then or equal
207     to the index of the port to which the sampler channel is connected.
208 iliev 1296 - The previous bindings were not been disconnected when altering
209     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
210     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
211 iliev 1297 - The active stream/voice count statistic was incorrect.
212 iliev 1298 - notification events were not been sent for some sampler
213     channel changes
214 iliev 1305 - added default min and max values to restrict the number of allowed
215     audio output channels and MIDI input ports
216 iliev 1306 - the connection to the PCM interface is now closed when destroying
217     an audio output device
218 schoenebeck 1332 - files with slash in their path or filename could not be loaded
219 iliev 959
220 schoenebeck 1221 * test cases:
221     - updated and fixed (haven't been touched in a while)
222    
223 schoenebeck 937 Version 0.4.0 (24 November 2006)
224 persson 696
225 schoenebeck 697 * packaging changes:
226 capela 868 - changed deprecated copyright attribute to license; added ldconfig
227     to post-(un)install steps; added devel package for liblinuxsampler;
228     to linuxsampler.spec (RPM)
229 schoenebeck 697 - install necessary development header files for allowing 3rd party
230     applications to link against liblinuxsampler
231     - liblinuxsampler's API documentation can be generated with 'make docs'
232     (Doxygen required)
233 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
234     implementation (currently either an integer math solution or a
235     di-harmonic approximation), automatic detection can be overriden
236     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
237     configure script argument though (mandatory for cross-compilation)
238 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
239     provided some on his own (as CXXFLAGS)
240 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
241     messages
242 schoenebeck 852 - added compile time options to allow disabling the various audio and
243     MIDI drivers
244 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
245     (patch by Ebrahim Mayat)
246 schoenebeck 697
247 persson 696 * Gigasampler format engine:
248 schoenebeck 738 - extensive synthesis optimization
249     (reimplementation of EGs and LFO(s), removed synthesis parameter
250     prerendering and the synthesis parameter matrix in general, splitting
251     each audio fragment into subfragments now where each subfragment uses
252 persson 830 constant pitch and filter coefficients. The volume coefficient is
253     linearly interpolated inside a subfragment, unless
254     --disable-interpolate-volume is set.)
255 persson 696 - fine tuning of the EG modulation parameters
256 persson 729 - improved filter cutoff calculation by adding support for the
257     following gig parameters: Cutoff freq (used when no cutoff
258     controller is defined), Control invert, Minimum cutoff, Velocity
259 persson 791 curve and Velocity range. The keyboard tracking now scales
260     cutoff frequency instead of resonance.
261 persson 877 - added support for gig parameter Resonance.
262 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
263 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
264     which can be overridden with --enable-global-attenuation
265 persson 783 - EG fixes: made the length of "attack hold" stage more
266     accurate. Release stage can now start before attack stage
267 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
268     time now has a minimal value to prevent clicks.
269 persson 799 - fixed pitch changes larger than one octave
270 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
271     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
272     all modes can be altered via standard GM messages, that is CC5 for
273     altering portamento time, CC65 for enabling / disabling portamento
274     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
275 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
276     parameter) and crossfade
277 persson 831 - added support for the "attenuation controller threshold" gig
278     parameter
279 persson 832 - added smoothing of volume changes caused by control change
280     messages
281 persson 865 - sample loop parameters are now taken from the DimensionRegion
282     instead of the wave chunk
283     - fixed keyswitching for v3 gigs with a number of keyswitch splits
284     not equal to a power of two
285 persson 877 - reimplementation of the filter algorithm. The new filter is more
286     accurate and supports all gig filter types, including bandreject
287     and lowpass turbo.
288 persson 903 - real support for 24 bit samples - samples are not truncated to
289     16 bits anymore
290     - support for aftertouch (channel pressure, not polyphonic
291     aftertouch)
292 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
293     amplifying from 0)
294 persson 696
295 schoenebeck 711 * LSCP server:
296     - fixed application exit on broken pipe error (fixes bug #20)
297 iliev 793 - fixed the notification messages delay due to lack of
298     network activity (fixes bug #26)
299 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
300     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
301 schoenebeck 711
302 schoenebeck 838 * audio driver:
303     - added aRts audio output driver (by no means RT safe)
304    
305 schoenebeck 775 * MIDI driver:
306     - fixed legacy sysex code which caused dispatching of MIDI SysEx
307     messages several times instead of once
308 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
309     for events (i.e. for offline rendering based MIDI drivers)
310 persson 922 - added checks for bad MIDI data
311 schoenebeck 775
312 schoenebeck 900 * linuxsampler application:
313     - show available sampler engine types on startup
314    
315 schoenebeck 705 * general changes:
316     - support for muting sampler channels and solo mode of the same, two new
317     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
318     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
319     introduced for this, the behavior is the same like on a mixer console
320 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
321     --enable-process-muted-channels which can be used to enable the
322     processing of muted channels.
323 iliev 777 - support for sostenuto pedal
324 iliev 779 - support for monitoring the total number of active voices
325 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
326     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
327 persson 835 - fixed some memory management errors
328 persson 841 - fixed some concurrency problems that could lead to crashes when
329     LSCP commands were executed
330 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
331     sampler channel (fixes bug #36)
332 schoenebeck 705
333 schoenebeck 692 Version 0.3.3 (15 July 2005)
334 schoenebeck 686
335     * packaging changes:
336     - fixed compilation with gcc 4.0
337    
338 schoenebeck 687 * Gigasampler format engine:
339     - LFO preprocessing was performed even though the respective LFO was
340     disabled by the instrument patch (minor efficiency fix)
341 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
342     for volume ramp downs in the same fragment (needed for current voice
343     stealing implementation) then simply inform the user with a warning
344     about possible click sounds and reduce the volume ramp down
345     appropriately instead of cancelling the audio device connection
346 schoenebeck 687
347 schoenebeck 677 Version 0.3.2 (24 June 2005)
348 schoenebeck 609
349     * packaging changes:
350     - updated autotools build files to compile on OS X
351     (conditional compilation of CoreMIDI and MidiShare drivers)
352 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
353     './configure --disable-asm' (definitely not recommended)
354 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
355     - require automake (>= 1.5) for 'make -f Makefile.cvs'
356     (due to 'dist-bzip2' automake option)
357 schoenebeck 649
358     * Gigasampler format engine:
359     - support for the gig parameters for "release velocity response" curves
360     - fine tuning of the EGADSR envelope
361     - volume of release triggered samples now depends on note-on velocity,
362     note length and gig parameter "release trigger decay" instead of
363     note-off velocity.
364 schoenebeck 663 - revised voice stealing
365     (fixes crash and endless loop caused by voice stealing)
366 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
367 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
368     instead of when the respective voice is actually launched
369     (fixes undefined behavior if stolen voices belonged to a key group -
370     this case was followed by a "killed voice survived" error message)
371 schoenebeck 669 - fixed minor issue with null/silence samples
372     (those stole voices even though they don't need a voice at all which
373     resulted in "voice stealing didn't work out" messages)
374 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
375     instrument or audio output device change
376 schoenebeck 654
377 schoenebeck 620 * LSCP server:
378 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
379 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
380 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
381 schoenebeck 609
382 schoenebeck 668 * linuxsampler application:
383     - added command line parameters --lscp-addr and --lscp-port to override
384     default IP address and port of LSCP server
385    
386 schoenebeck 579 Version 0.3.1 (24 May 2005)
387    
388     * initial release
