* ensure that a notification event is sent when already
  loaded instrument is assigned to another sampler channel

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