* fixed buggy boolean --enable-foo / --disable-foo configure script
  parameters

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