* minor assembly fix in x86 features detection (don't use the PIC
  register, to avoid relocations in the text segment at runtime)

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