* LSCP server: added support for Windows style path / filenames, however
  with forward slash path separators instead of backslash
  (i.e. "C:/foo/bar.gig")

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