* fixes in Ringbuffer.h:
 - fill_write_space_with_null() did not zero out all the space
 - operator--() did not apply size_mask after decrementing the read_ptr
  (might fix bug #48)
 - DEFAULT_WRAP_ELEMENTS set to 0 in order to avoid problems with
  the _NonVolatileReader functions.

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

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