Sun Oct 7 14:05:04 2007 UTC (12 years, 2 months ago) by schoenebeck
File size: 16647 byte(s)
* the following LSCP commands now also support escape sequences for at
  least one of their text-based arguments (i.e. name, description):
  "ADD MIDI_INSTRUMENT_MAP", "SET MIDI_INSTRUMENT_MAP NAME",
  "SET FX_SEND NAME", "CREATE FX_SEND"
* the LSCP spec doc now lists all LSCP commands which support escape
  sequences as one of their arguments

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 1389 - the following LSCP commands now also support escape sequences for at
114     least one of their text-based parameters (i.e. name, description):
115     "ADD MIDI_INSTRUMENT_MAP", "MAP MIDI_INSTRUMENT",
116     "SET MIDI_INSTRUMENT_MAP NAME", "SET FX_SEND NAME", "CREATE FX_SEND",
117     "SET DB_INSTRUMENT_DIRECTORY NAME",
118     "SET DB_INSTRUMENT_DIRECTORY DESCRIPTION", "SET DB_INSTRUMENT NAME",
119     "SET DB_INSTRUMENT DESCRIPTION", "FIND DB_INSTRUMENTS",
120     "FIND DB_INSTRUMENT_DIRECTORIES"
121 schoenebeck 1252 - returns verbose syntax errors (line and column where syntax error
122     occured, the unexpected character and the actually expected, possible
123     character(s), the latter only if less than 5 possibilities)
124 persson 1349 - made sure that LSCP syntax is not affected by gigedit locale
125     settings
126 schoenebeck 1379 - bugfix regarding strings parameter lists: all comma separated lists
127     of strings were treated as being one string containing commas
128     (fixes #57)
129 schoenebeck 1244
130 iliev 959 * Bug fixes:
131     - fixed crash occurring on certain LSCP scripts (Bug 39)
132 persson 1038 - another thread safety fix for lscp "load engine" and "set
133     channel audio output device"
134 iliev 1283 - fixed a crash which occurs when reassigning the same engine
135     on a sampler channel with connected MIDI device
136 iliev 1295 - fixed a crash which occurs when changing the number of ports of a MIDI
137     device connected to a sampler channel to number less then or equal
138     to the index of the port to which the sampler channel is connected.
139 iliev 1296 - The previous bindings were not been disconnected when altering
140     the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
141     unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
142 iliev 1297 - The active stream/voice count statistic was incorrect.
143 iliev 1298 - notification events were not been sent for some sampler
144     channel changes
145 iliev 1305 - added default min and max values to restrict the number of allowed
146     audio output channels and MIDI input ports
147 iliev 1306 - the connection to the PCM interface is now closed when destroying
148     an audio output device
149 schoenebeck 1332 - files with slash in their path or filename could not be loaded
150 iliev 959
151 schoenebeck 1221 * test cases:
152     - updated and fixed (haven't been touched in a while)
153    
154 schoenebeck 937 Version 0.4.0 (24 November 2006)
155 persson 696
156 schoenebeck 697 * packaging changes:
157 capela 868 - changed deprecated copyright attribute to license; added ldconfig
158     to post-(un)install steps; added devel package for liblinuxsampler;
159     to linuxsampler.spec (RPM)
160 schoenebeck 697 - install necessary development header files for allowing 3rd party
161     applications to link against liblinuxsampler
162     - liblinuxsampler's API documentation can be generated with 'make docs'
163     (Doxygen required)
164 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
165     implementation (currently either an integer math solution or a
166     di-harmonic approximation), automatic detection can be overriden
167     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
168     configure script argument though (mandatory for cross-compilation)
169 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
170     provided some on his own (as CXXFLAGS)
171 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
172     messages
173 schoenebeck 852 - added compile time options to allow disabling the various audio and
174     MIDI drivers
175 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
176     (patch by Ebrahim Mayat)
177 schoenebeck 697
178 persson 696 * Gigasampler format engine:
179 schoenebeck 738 - extensive synthesis optimization
180     (reimplementation of EGs and LFO(s), removed synthesis parameter
181     prerendering and the synthesis parameter matrix in general, splitting
182     each audio fragment into subfragments now where each subfragment uses
183 persson 830 constant pitch and filter coefficients. The volume coefficient is
184     linearly interpolated inside a subfragment, unless
185     --disable-interpolate-volume is set.)
186 persson 696 - fine tuning of the EG modulation parameters
187 persson 729 - improved filter cutoff calculation by adding support for the
188     following gig parameters: Cutoff freq (used when no cutoff
189     controller is defined), Control invert, Minimum cutoff, Velocity
190 persson 791 curve and Velocity range. The keyboard tracking now scales
191     cutoff frequency instead of resonance.
192 persson 877 - added support for gig parameter Resonance.
193 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
194 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
195     which can be overridden with --enable-global-attenuation
196 persson 783 - EG fixes: made the length of "attack hold" stage more
197     accurate. Release stage can now start before attack stage
198 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
199     time now has a minimal value to prevent clicks.
200 persson 799 - fixed pitch changes larger than one octave
201 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
202     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
203     all modes can be altered via standard GM messages, that is CC5 for
204     altering portamento time, CC65 for enabling / disabling portamento
205     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
206 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
207     parameter) and crossfade
208 persson 831 - added support for the "attenuation controller threshold" gig
209     parameter
210 persson 832 - added smoothing of volume changes caused by control change
211     messages
212 persson 865 - sample loop parameters are now taken from the DimensionRegion
213     instead of the wave chunk
214     - fixed keyswitching for v3 gigs with a number of keyswitch splits
215     not equal to a power of two
216 persson 877 - reimplementation of the filter algorithm. The new filter is more
217     accurate and supports all gig filter types, including bandreject
218     and lowpass turbo.
219 persson 903 - real support for 24 bit samples - samples are not truncated to
220     16 bits anymore
221     - support for aftertouch (channel pressure, not polyphonic
222     aftertouch)
223 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
224     amplifying from 0)
225 persson 696
226 schoenebeck 711 * LSCP server:
227     - fixed application exit on broken pipe error (fixes bug #20)
228 iliev 793 - fixed the notification messages delay due to lack of
229     network activity (fixes bug #26)
230 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
231     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
232 schoenebeck 711
233 schoenebeck 838 * audio driver:
234     - added aRts audio output driver (by no means RT safe)
235    
236 schoenebeck 775 * MIDI driver:
237     - fixed legacy sysex code which caused dispatching of MIDI SysEx
238     messages several times instead of once
239 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
240     for events (i.e. for offline rendering based MIDI drivers)
241 persson 922 - added checks for bad MIDI data
242 schoenebeck 775
243 schoenebeck 900 * linuxsampler application:
244     - show available sampler engine types on startup
245    
246 schoenebeck 705 * general changes:
247     - support for muting sampler channels and solo mode of the same, two new
248     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
249     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
250     introduced for this, the behavior is the same like on a mixer console
251 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
252     --enable-process-muted-channels which can be used to enable the
253     processing of muted channels.
254 iliev 777 - support for sostenuto pedal
255 iliev 779 - support for monitoring the total number of active voices
256 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
257     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
258 persson 835 - fixed some memory management errors
259 persson 841 - fixed some concurrency problems that could lead to crashes when
260     LSCP commands were executed
261 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
262     sampler channel (fixes bug #36)
263 schoenebeck 705
264 schoenebeck 692 Version 0.3.3 (15 July 2005)
265 schoenebeck 686
266     * packaging changes:
267     - fixed compilation with gcc 4.0
268    
269 schoenebeck 687 * Gigasampler format engine:
270     - LFO preprocessing was performed even though the respective LFO was
271     disabled by the instrument patch (minor efficiency fix)
272 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
273     for volume ramp downs in the same fragment (needed for current voice
274     stealing implementation) then simply inform the user with a warning
275     about possible click sounds and reduce the volume ramp down
276     appropriately instead of cancelling the audio device connection
277 schoenebeck 687
278 schoenebeck 677 Version 0.3.2 (24 June 2005)
279 schoenebeck 609
280     * packaging changes:
281     - updated autotools build files to compile on OS X
282     (conditional compilation of CoreMIDI and MidiShare drivers)
283 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
284     './configure --disable-asm' (definitely not recommended)
285 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
286     - require automake (>= 1.5) for 'make -f Makefile.cvs'
287     (due to 'dist-bzip2' automake option)
288 schoenebeck 649
289     * Gigasampler format engine:
290     - support for the gig parameters for "release velocity response" curves
291     - fine tuning of the EGADSR envelope
292     - volume of release triggered samples now depends on note-on velocity,
293     note length and gig parameter "release trigger decay" instead of
294     note-off velocity.
295 schoenebeck 663 - revised voice stealing
296     (fixes crash and endless loop caused by voice stealing)
297 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
298 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
299     instead of when the respective voice is actually launched
300     (fixes undefined behavior if stolen voices belonged to a key group -
301     this case was followed by a "killed voice survived" error message)
302 schoenebeck 669 - fixed minor issue with null/silence samples
303     (those stole voices even though they don't need a voice at all which
304     resulted in "voice stealing didn't work out" messages)
305 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
306     instrument or audio output device change
307 schoenebeck 654
308 schoenebeck 620 * LSCP server:
309 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
310 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
311 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
312 schoenebeck 609
313 schoenebeck 668 * linuxsampler application:
314     - added command line parameters --lscp-addr and --lscp-port to override
315     default IP address and port of LSCP server
316    
317 schoenebeck 579 Version 0.3.1 (24 May 2005)
318    
319     * initial release
