* autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
  causing e.g. the libgig test to fail when
  "./configure --disable-jack-driver" was used
  (patch by Alexis Ballier)

1 Version CVS HEAD (?)
2
3 * packaging changes:
4 - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
5 causing e.g. the libgig test to fail when
6 "./configure --disable-jack-driver" was used
7 (patch by Alexis Ballier)
8
9 * general changes:
10 - bugfix: on some POSIX systems instrument editor plugins refused to
11 load as we used a non-portable Linux specific struct field
12 (fixes bug #70, patch by Ronald Baljeu)
13 - fixed endless loop which occured when loading an instrument editor
14 plugin DLL on Windows systems failed
15
16 * audio driver:
17 - removed the nonsense audio channel constraint (which was hard coded to
18 max. 100 audio channels) for most audio drivers
19 - JACK audio driver did not offer a device parameter "SAMPLERATE" as
20 opposed to the LSCP specs
21 - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
22 reflected the wrong value
23
24 * instruments database:
25 - avoid time consuming samples scanning when adding instruments
26 to the instruments database
27
28 Version 0.5.1 (6 December 2007)
29
30 * packaging changes:
31 - added autoconf checks for pthread library
32 - added autoconf check for pthread bug found on certain NPTL-enabled
33 glibc versions (see Gentoo bug report #194076)
34 - added autoconf checks for MS Windows
35
36 * general changes:
37 - bugfix: the thread used by an editor plugin didn't die when the
38 editor closed
39 - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
40 out all the space. operator--() did not apply size_mask after
41 decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
42 order to avoid problems with the _NonVolatileReader functions.
43 - bugfix: Stream.h: added a missing divide by BytesPerSample in
44 GetWriteSpace(). Since this function is currently only used in
45 the stream's qsort() compare function, it didn't trigger any
46 bugs.
47 - Resampler.h, Synthesizer.h: cubic interpolation now works in
48 24bit mode too. Faster method to read 24bit words on little
49 endian machines (x86): replaced 3 byte reads + shifts with a 1
50 unaligned 32bit read and shift
51 - experimental support for MS Windows (MIDI input via MME, AUDIO
52 output via ASIO)
53 - made handling of SIGINT signal (Ctrl-C) a bit more robust
54 - support for monitoring the total number of active disk streams
55 (new LSCP commands: GET TOTAL_STREAM_COUNT,
56 SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
57
58 * AUDIO driver:
59 - added Windows ASIO low latency audio driver
60
61 * MIDI driver:
62 - added MME Windows MIDI driver
63
64 * LSCP server:
65 - added support for Windows style path / filenames, however with
66 forward slash path separators instead of backslash
67 (i.e. "C:/foo/bar.gig")
68 - allow naughty liblscp to send non-string device parameters within
69 apostrophes as well
70 - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
71 "LIST FILE INSTRUMENTS <file>" and
72 "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
73 about an arbitrary instrument file on the system where the sampler is
74 running on
75
76 Version 0.5.0 (15 October 2007)
77
78 * packaging changes:
79 - config.h is not going to be installed along with liblinuxsampler's
80 API header files anymore
81 - only the API relevant header (and source) files will be exported to
82 the Doxygen API documentation (explicitly listed in Doxyfile.in)
83 - added completely new XCode project files for Mac OSX which is now
84 capable to execute our autoconf environment, thus no need anymore
85 to maintain the compile time configuration file (osx/version.h) for
86 OSX manually (patch by Toshi Nagata)
87 - fixed buggy boolean --enable-foo / --disable-foo configure script
88 parameters
89 - global.h now only covers global definitions that are needed for the
90 C++ API header files, all implementation internal global definitions
91 are now in global_private.h
92 - atomic.h is not exposed to the C++ API anymore
93 - no need to include config.h anymore for using LS's API header files
94 - fixed warnings in API doc generation
95
96 * general changes:
97 - replaced the old, confusing MIDI program change mechanism by a
98 flexible MIDI instrument mapper which allows to map arbitrary
99 (MIDI bank, MIDI program) pairs with arbitrary
100 (engine type, instrument file, file index) triplets which will be
101 loaded on the respective channel when such MIDI program change
102 messages arrive, beside that, each entry allows to define a life-time
103 strategy for the instrument, so the user can define whether the
104 instrument should i.e. be permanently loaded (to be able to switch
105 quickly among sounds) or i.e. loaded just on demand when the
106 respective program change arrives (to safe RAM space), as well as a
107 global volume factor for each entry, so the user can adjust the volume
108 dynamic of his mapped instrument collection without having to modify
109 the instrument files, also one can manage arbitrary amount of such
110 MIDI instrument maps and assign each sampler channel individually
111 a certain map, so that i.e. separation of normal instruments and
112 drumkits is possible
113 - new notification events for tracking changes to audio/MIDI devices,
114 MIDI instrument maps, MIDI instruments, FX sends, global volume.
115 - sampler was limited to load max. 200 instruments in the background
116 due to a constant size RingBuffer FIFO which is now replaced by a
117 dynamic (unlimited) size std::list FIFO
118 - added FX sends, these allow to route audio signals to arbitrary audio
119 output channels for being processed by external effect processors
120 (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
121 controllers
122 - global (sampler wide) volume can now be controlled at runtime
123 - Implemented new, improved notification system
124 - fixed compilation errors regarding OSX
125 (patch by Toshi Nagata)
126 - implemented instruments database
127 - added support for escape sequences to the instruments database
128 - added highly experimental support for on-the-fly instrument editing
129 within the sampler's process (by using instrument editor plugins),
130 you'll notice the new "Registered instrument editors:" message on
131 startup, added a new LSCP command:
132 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
133 to spawn a matching instrument editor for the instrument on the
134 given sampler channel, the plugin path can be overridden at compile
135 time with ./configure --enable-plugin-dir=/some/dir
136 - added experimental code for synchronizing instrument editors hosted
137 in the sampler's process to safely edit instruments while playing
138 without a crash (hopefully) by either suspending single regions
139 wherever possible or if unavoidable whole engine(s)
140 - fixed several issues in fundamental "Thread" class: set scheduling
141 policy and priority on thread level, set a minimum stack size for
142 thread (TODO: a reasonable value yet to be tested), bugfix: non-RT
143 threads simply inherited properties of starting thread instead of
144 setting their own policy and priority
145 - minor fix in our automatic stack trace mechanism on crashes, the
146 main process did not wait for the stack trace process to finish
147 its output
148 - fixed some minor memory leaks
149 - reenabled assembly features support, at the moment only for
150 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
151 - minor assembly fix in x86 features detection (don't use the PIC
152 register, to avoid relocations in the text segment at runtime)
153 - POSIX callback functions of Thread.h are hidden
154
155 * MIDI driver:
156 - dispatch bank select (MSB and LSB) messages
157
158 * audio driver:
159 - the ALSA audio output driver parameters now reflect the correct
160 parameter value ranges for the respective selected sound card
161 (patch by Till Wimmer, a bit fixed and extended)
162
163 * Gigasampler format engine:
164 - if a filter is used and EG2 finishes before EG1, let the voice
165 die when EG2 has finished (this fixes a problem with clicks and
166 voice starvation for some gigs)
167 - playback is no longer disabled during instrument loading
168 - all notes playing on a channel that changes its instrument keep
169 playing with the old instrument until they get a note off
170 command
171 - EG fix: a release value of zero could cause noises or crash
172 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
173 - EG fine tuning: when attack is zero the EG starts at a level
174 above max sustain level, which means that there is a decay phase
175 even if sustain is 100%
176 - more EG fixes: the level could sometimes go below zero and cause
177 noises or crashes
178 - minor fix of EGDecay (patch by Toshi Nagata)
179 - fixed compiler error when --enable-override-filter-type was
180 supplied to the configure script (fixes #46)
181 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
182 instead of a fix value
183 - behavior fix: on MIDI CC# 65 (portamento on / off), 126 (mono mode),
184 127 (solo mode) only kill voices if the respective mode really
185 changed
186
187 * LSCP server:
188 - fixed compile time error for old Bison versions
189 (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
190 - parser now supports extended ASCII character set
191 (up to ASCII code 255, i.e. includes now umlauts and accents)
192 - filename arguments in LSCP commands now allow to use escape
193 sequences, that is directly literal as one of: \', \", \\, \n, \r,
194 \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
195 code value like \xf2) (fixes bug #24)
196 - the following LSCP commands now also support escape sequences for at
197 least one of their text-based parameters (i.e. name, description):
198 "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
199 "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
200 "SET DB_INSTRUMENT_DIRECTORY NAME",
201 "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
202 "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
203 "FIND DB_INSTRUMENT_DIRECTORIES"
204 - returns verbose syntax errors (line and column where syntax error
205 occured, the unexpected character and the actually expected, possible
206 character(s), the latter only if less than 5 possibilities)
207 - made sure that LSCP syntax is not affected by gigedit locale
208 settings
209 - bugfix regarding strings parameter lists: all comma separated lists
210 of strings were treated as being one string containing commas
211 (fixes #57)
212
213 * Bug fixes:
214 - fixed crash occurring on certain LSCP scripts (Bug 39)
215 - another thread safety fix for lscp "load engine" and "set
216 channel audio output device"
217 - fixed a crash which occurs when reassigning the same engine
218 on a sampler channel with connected MIDI device
219 - fixed a crash which occurs when changing the number of ports of a MIDI
220 device connected to a sampler channel to number less then or equal
221 to the index of the port to which the sampler channel is connected.
222 - The previous bindings were not been disconnected when altering
223 the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
224 unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
225 - The active stream/voice count statistic was incorrect.
226 - notification events were not been sent for some sampler
227 channel changes
228 - added default min and max values to restrict the number of allowed
229 audio output channels and MIDI input ports
230 - the connection to the PCM interface is now closed when destroying
231 an audio output device
232 - files with slash in their path or filename could not be loaded
233
234 * test cases:
235 - updated and fixed (haven't been touched in a while)
236
237 Version 0.4.0 (24 November 2006)
238
239 * packaging changes:
240 - changed deprecated copyright attribute to license; added ldconfig
241 to post-(un)install steps; added devel package for liblinuxsampler;
242 to linuxsampler.spec (RPM)
243 - install necessary development header files for allowing 3rd party
244 applications to link against liblinuxsampler
245 - liblinuxsampler's API documentation can be generated with 'make docs'
246 (Doxygen required)
247 - added benchmark to automatically detect the best triangle LFO
248 implementation (currently either an integer math solution or a
249 di-harmonic approximation), automatic detection can be overriden
250 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
251 configure script argument though (mandatory for cross-compilation)
252 - do not automatically pick optimized gcc flags if the user already
253 provided some on his own (as CXXFLAGS)
254 - added compile time option to disable processing of All-Notes-Off MIDI
255 messages
256 - added compile time options to allow disabling the various audio and
257 MIDI drivers
258 - fixed automatic GCC CPU switch detection on PPC
259 (patch by Ebrahim Mayat)
260
261 * Gigasampler format engine:
262 - extensive synthesis optimization
263 (reimplementation of EGs and LFO(s), removed synthesis parameter
264 prerendering and the synthesis parameter matrix in general, splitting
265 each audio fragment into subfragments now where each subfragment uses
266 constant pitch and filter coefficients. The volume coefficient is
267 linearly interpolated inside a subfragment, unless
268 --disable-interpolate-volume is set.)
269 - fine tuning of the EG modulation parameters
270 - improved filter cutoff calculation by adding support for the
271 following gig parameters: Cutoff freq (used when no cutoff
272 controller is defined), Control invert, Minimum cutoff, Velocity
273 curve and Velocity range. The keyboard tracking now scales
274 cutoff frequency instead of resonance.
275 - added support for gig parameter Resonance.
276 - fixed bug in sysex handling (patch by Juan Linietsky)
277 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
278 which can be overridden with --enable-global-attenuation
279 - EG fixes: made the length of "attack hold" stage more
280 accurate. Release stage can now start before attack stage
281 ends. Cancel release didn't work when sustain was zero. Attack
282 time now has a minimal value to prevent clicks.
283 - fixed pitch changes larger than one octave
284 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
285 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
286 all modes can be altered via standard GM messages, that is CC5 for
287 altering portamento time, CC65 for enabling / disabling portamento
288 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
289 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
290 parameter) and crossfade
291 - added support for the "attenuation controller threshold" gig
292 parameter
293 - added smoothing of volume changes caused by control change
294 messages
295 - sample loop parameters are now taken from the DimensionRegion
296 instead of the wave chunk
297 - fixed keyswitching for v3 gigs with a number of keyswitch splits
298 not equal to a power of two
299 - reimplementation of the filter algorithm. The new filter is more
300 accurate and supports all gig filter types, including bandreject
301 and lowpass turbo.
302 - real support for 24 bit samples - samples are not truncated to
303 16 bits anymore
304 - support for aftertouch (channel pressure, not polyphonic
305 aftertouch)
306 - LFO1 behaviour fixed (dampening from max volume instead of
307 amplifying from 0)
308
309 * LSCP server:
310 - fixed application exit on broken pipe error (fixes bug #20)
311 - fixed the notification messages delay due to lack of
312 network activity (fixes bug #26)
313 - fixed parser bug which occured on space(s) within device parameters
314 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
315
316 * audio driver:
317 - added aRts audio output driver (by no means RT safe)
318
319 * MIDI driver:
320 - fixed legacy sysex code which caused dispatching of MIDI SysEx
321 messages several times instead of once
322 - API extension for MIDI drivers which already supply exact time stamps
323 for events (i.e. for offline rendering based MIDI drivers)
324 - added checks for bad MIDI data
325
326 * linuxsampler application:
327 - show available sampler engine types on startup
328
329 * general changes:
330 - support for muting sampler channels and solo mode of the same, two new
331 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
332 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
333 introduced for this, the behavior is the same like on a mixer console
334 (patch by Grigor Iliev, a bit adjusted). Also added configure option
335 --enable-process-muted-channels which can be used to enable the
336 processing of muted channels.
337 - support for sostenuto pedal
338 - support for monitoring the total number of active voices
339 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
340 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
341 - fixed some memory management errors
342 - fixed some concurrency problems that could lead to crashes when
343 LSCP commands were executed
344 - fixed crash when instrument loading failed previously on the same
345 sampler channel (fixes bug #36)
346
347 Version 0.3.3 (15 July 2005)
348
349 * packaging changes:
350 - fixed compilation with gcc 4.0
351
352 * Gigasampler format engine:
353 - LFO preprocessing was performed even though the respective LFO was
354 disabled by the instrument patch (minor efficiency fix)
355 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
356 for volume ramp downs in the same fragment (needed for current voice
357 stealing implementation) then simply inform the user with a warning
358 about possible click sounds and reduce the volume ramp down
359 appropriately instead of cancelling the audio device connection
360
361 Version 0.3.2 (24 June 2005)
362
363 * packaging changes:
364 - updated autotools build files to compile on OS X
365 (conditional compilation of CoreMIDI and MidiShare drivers)
366 - hand-crafted assembly optimization code can be disabled with
367 './configure --disable-asm' (definitely not recommended)
368 - fixed 'make dist' rule to include all necessary files
369 - require automake (>= 1.5) for 'make -f Makefile.cvs'
370 (due to 'dist-bzip2' automake option)
371
372 * Gigasampler format engine:
373 - support for the gig parameters for "release velocity response" curves
374 - fine tuning of the EGADSR envelope
375 - volume of release triggered samples now depends on note-on velocity,
376 note length and gig parameter "release trigger decay" instead of
377 note-off velocity.
378 - revised voice stealing
379 (fixes crash and endless loop caused by voice stealing)
380 - don't reset scale tuning on instrument or audio output device change
381 - handle key group conflicts right at the beginning of each fragment
382 instead of when the respective voice is actually launched
383 (fixes undefined behavior if stolen voices belonged to a key group -
384 this case was followed by a "killed voice survived" error message)
385 - fixed minor issue with null/silence samples
386 (those stole voices even though they don't need a voice at all which
387 resulted in "voice stealing didn't work out" messages)
388 - don't reset volume, pan, pitch and MIDI controller values on
389 instrument or audio output device change
390
391 * LSCP server:
392 - fixed some crashes (patch by Grigor Iliev, fixes #19)
393 - fixed LSCP event "CHANNEL_INFO" notification
394 (e.g. did not notify on volume changes or MIDI program change events)
395
396 * linuxsampler application:
397 - added command line parameters --lscp-addr and --lscp-port to override
398 default IP address and port of LSCP server
399
400 Version 0.3.1 (24 May 2005)
401
402 * initial release
