* 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 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 * general changes:
9 - bugfix: the thread used by an editor plugin didn't die when the
10 editor closed
11
12 * 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 Version 0.5.0 (15 October 2007)
18
19 * packaging changes:
20 - config.h is not going to be installed along with liblinuxsampler's
21 API header files anymore
22 - only the API relevant header (and source) files will be exported to
23 the Doxygen API documentation (explicitly listed in Doxyfile.in)
24 - 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 - fixed buggy boolean --enable-foo / --disable-foo configure script
29 parameters
30 - 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
37 * general changes:
38 - replaced the old, confusing MIDI program change mechanism by a
39 flexible MIDI instrument mapper which allows to map arbitrary
40 (MIDI bank, MIDI program) pairs with arbitrary
41 (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 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 - new notification events for tracking changes to audio/MIDI devices,
55 MIDI instrument maps, MIDI instruments, FX sends, global volume.
56 - 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 - 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 - global (sampler wide) volume can now be controlled at runtime
64 - Implemented new, improved notification system
65 - fixed compilation errors regarding OSX
66 (patch by Toshi Nagata)
67 - implemented instruments database
68 - added support for escape sequences to the instruments database
69 - 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 startup, added a new LSCP command:
73 "EDIT CHANNEL INSTRUMENT <sampler-channel>"
74 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 - 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 - 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 - 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 - fixed some minor memory leaks
90 - reenabled assembly features support, at the moment only for
91 enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
92 - minor assembly fix in x86 features detection (don't use the PIC
93 register, to avoid relocations in the text segment at runtime)
94 - POSIX callback functions of Thread.h are hidden
95
96 * MIDI driver:
97 - dispatch bank select (MSB and LSB) messages
98
99 * 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 * 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 - 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 - EG fix: a release value of zero could cause noises or crash
113 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
114 - 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 - more EG fixes: the level could sometimes go below zero and cause
118 noises or crashes
119 - minor fix of EGDecay (patch by Toshi Nagata)
120 - fixed compiler error when --enable-override-filter-type was
121 supplied to the configure script (fixes #46)
122 - disk thread: queue sizes are now proportional to CONFIG_MAX_STREAMS
123 instead of a fix value
124 - 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
128 * 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 - 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 - 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 - 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 - made sure that LSCP syntax is not affected by gigedit locale
149 settings
150 - bugfix regarding strings parameter lists: all comma separated lists
151 of strings were treated as being one string containing commas
152 (fixes #57)
153
154 * Bug fixes:
155 - fixed crash occurring on certain LSCP scripts (Bug 39)
156 - another thread safety fix for lscp "load engine" and "set
157 channel audio output device"
158 - fixed a crash which occurs when reassigning the same engine
159 on a sampler channel with connected MIDI device
160 - 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 - 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 - The active stream/voice count statistic was incorrect.
167 - notification events were not been sent for some sampler
168 channel changes
169 - added default min and max values to restrict the number of allowed
170 audio output channels and MIDI input ports
171 - the connection to the PCM interface is now closed when destroying
172 an audio output device
173 - files with slash in their path or filename could not be loaded
174
175 * test cases:
176 - updated and fixed (haven't been touched in a while)
177
178 Version 0.4.0 (24 November 2006)
179
180 * packaging changes:
181 - 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 - 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 - 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 - do not automatically pick optimized gcc flags if the user already
194 provided some on his own (as CXXFLAGS)
195 - added compile time option to disable processing of All-Notes-Off MIDI
196 messages
197 - added compile time options to allow disabling the various audio and
198 MIDI drivers
199 - fixed automatic GCC CPU switch detection on PPC
200 (patch by Ebrahim Mayat)
201
202 * Gigasampler format engine:
203 - 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 constant pitch and filter coefficients. The volume coefficient is
208 linearly interpolated inside a subfragment, unless
209 --disable-interpolate-volume is set.)
210 - fine tuning of the EG modulation parameters
211 - 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 curve and Velocity range. The keyboard tracking now scales
215 cutoff frequency instead of resonance.
216 - added support for gig parameter Resonance.
217 - fixed bug in sysex handling (patch by Juan Linietsky)
218 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
219 which can be overridden with --enable-global-attenuation
220 - EG fixes: made the length of "attack hold" stage more
221 accurate. Release stage can now start before attack stage
222 ends. Cancel release didn't work when sustain was zero. Attack
223 time now has a minimal value to prevent clicks.
224 - fixed pitch changes larger than one octave
225 - 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 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
231 parameter) and crossfade
232 - added support for the "attenuation controller threshold" gig
233 parameter
234 - added smoothing of volume changes caused by control change
235 messages
236 - 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 - 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 - 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 - LFO1 behaviour fixed (dampening from max volume instead of
248 amplifying from 0)
249
250 * LSCP server:
251 - fixed application exit on broken pipe error (fixes bug #20)
252 - fixed the notification messages delay due to lack of
253 network activity (fixes bug #26)
254 - 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
257 * audio driver:
258 - added aRts audio output driver (by no means RT safe)
259
260 * MIDI driver:
261 - fixed legacy sysex code which caused dispatching of MIDI SysEx
262 messages several times instead of once
263 - API extension for MIDI drivers which already supply exact time stamps
264 for events (i.e. for offline rendering based MIDI drivers)
265 - added checks for bad MIDI data
266
267 * linuxsampler application:
268 - show available sampler engine types on startup
269
270 * 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 (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 - support for sostenuto pedal
279 - support for monitoring the total number of active voices
280 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
281 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
282 - fixed some memory management errors
283 - fixed some concurrency problems that could lead to crashes when
284 LSCP commands were executed
285 - fixed crash when instrument loading failed previously on the same
286 sampler channel (fixes bug #36)
287
288 Version 0.3.3 (15 July 2005)
289
290 * packaging changes:
291 - fixed compilation with gcc 4.0
292
293 * Gigasampler format engine:
294 - LFO preprocessing was performed even though the respective LFO was
295 disabled by the instrument patch (minor efficiency fix)
296 - 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
302 Version 0.3.2 (24 June 2005)
303
304 * packaging changes:
305 - updated autotools build files to compile on OS X
306 (conditional compilation of CoreMIDI and MidiShare drivers)
307 - hand-crafted assembly optimization code can be disabled with
308 './configure --disable-asm' (definitely not recommended)
309 - 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
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 - revised voice stealing
320 (fixes crash and endless loop caused by voice stealing)
321 - don't reset scale tuning on instrument or audio output device change
322 - 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 - 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 - don't reset volume, pan, pitch and MIDI controller values on
330 instrument or audio output device change
331
332 * LSCP server:
333 - fixed some crashes (patch by Grigor Iliev, fixes #19)
334 - fixed LSCP event "CHANNEL_INFO" notification
335 (e.g. did not notify on volume changes or MIDI program change events)
336
337 * 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 Version 0.3.1 (24 May 2005)
342
343 * initial release
