* reenabled assembly features support, at the moment only for
  enabling a fast denormal FPU mode (x86 platforms supporting SSE2)
* bumped version to 0.4.0.6cvs

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 959
108 schoenebeck 1221 * test cases:
109     - updated and fixed (haven't been touched in a while)
110    
111 schoenebeck 937 Version 0.4.0 (24 November 2006)
112 persson 696
113 schoenebeck 697 * packaging changes:
114 capela 868 - changed deprecated copyright attribute to license; added ldconfig
115     to post-(un)install steps; added devel package for liblinuxsampler;
116     to linuxsampler.spec (RPM)
117 schoenebeck 697 - install necessary development header files for allowing 3rd party
118     applications to link against liblinuxsampler
119     - liblinuxsampler's API documentation can be generated with 'make docs'
120     (Doxygen required)
121 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
122     implementation (currently either an integer math solution or a
123     di-harmonic approximation), automatic detection can be overriden
124     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
125     configure script argument though (mandatory for cross-compilation)
126 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
127     provided some on his own (as CXXFLAGS)
128 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
129     messages
130 schoenebeck 852 - added compile time options to allow disabling the various audio and
131     MIDI drivers
132 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
133     (patch by Ebrahim Mayat)
134 schoenebeck 697
135 persson 696 * Gigasampler format engine:
136 schoenebeck 738 - extensive synthesis optimization
137     (reimplementation of EGs and LFO(s), removed synthesis parameter
138     prerendering and the synthesis parameter matrix in general, splitting
139     each audio fragment into subfragments now where each subfragment uses
140 persson 830 constant pitch and filter coefficients. The volume coefficient is
141     linearly interpolated inside a subfragment, unless
142     --disable-interpolate-volume is set.)
143 persson 696 - fine tuning of the EG modulation parameters
144 persson 729 - improved filter cutoff calculation by adding support for the
145     following gig parameters: Cutoff freq (used when no cutoff
146     controller is defined), Control invert, Minimum cutoff, Velocity
147 persson 791 curve and Velocity range. The keyboard tracking now scales
148     cutoff frequency instead of resonance.
149 persson 877 - added support for gig parameter Resonance.
150 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
151 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
152     which can be overridden with --enable-global-attenuation
153 persson 783 - EG fixes: made the length of "attack hold" stage more
154     accurate. Release stage can now start before attack stage
155 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
156     time now has a minimal value to prevent clicks.
157 persson 799 - fixed pitch changes larger than one octave
158 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
159     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
160     all modes can be altered via standard GM messages, that is CC5 for
161     altering portamento time, CC65 for enabling / disabling portamento
162     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
163 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
164     parameter) and crossfade
165 persson 831 - added support for the "attenuation controller threshold" gig
166     parameter
167 persson 832 - added smoothing of volume changes caused by control change
168     messages
169 persson 865 - sample loop parameters are now taken from the DimensionRegion
170     instead of the wave chunk
171     - fixed keyswitching for v3 gigs with a number of keyswitch splits
172     not equal to a power of two
173 persson 877 - reimplementation of the filter algorithm. The new filter is more
174     accurate and supports all gig filter types, including bandreject
175     and lowpass turbo.
176 persson 903 - real support for 24 bit samples - samples are not truncated to
177     16 bits anymore
178     - support for aftertouch (channel pressure, not polyphonic
179     aftertouch)
180 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
181     amplifying from 0)
182 persson 696
183 schoenebeck 711 * LSCP server:
184     - fixed application exit on broken pipe error (fixes bug #20)
185 iliev 793 - fixed the notification messages delay due to lack of
186     network activity (fixes bug #26)
187 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
188     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
189 schoenebeck 711
190 schoenebeck 838 * audio driver:
191     - added aRts audio output driver (by no means RT safe)
192    
193 schoenebeck 775 * MIDI driver:
194     - fixed legacy sysex code which caused dispatching of MIDI SysEx
195     messages several times instead of once
196 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
197     for events (i.e. for offline rendering based MIDI drivers)
198 persson 922 - added checks for bad MIDI data
199 schoenebeck 775
200 schoenebeck 900 * linuxsampler application:
201     - show available sampler engine types on startup
202    
203 schoenebeck 705 * general changes:
204     - support for muting sampler channels and solo mode of the same, two new
205     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
206     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
207     introduced for this, the behavior is the same like on a mixer console
208 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
209     --enable-process-muted-channels which can be used to enable the
210     processing of muted channels.
211 iliev 777 - support for sostenuto pedal
212 iliev 779 - support for monitoring the total number of active voices
213 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
214     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
215 persson 835 - fixed some memory management errors
216 persson 841 - fixed some concurrency problems that could lead to crashes when
217     LSCP commands were executed
218 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
219     sampler channel (fixes bug #36)
220 schoenebeck 705
221 schoenebeck 692 Version 0.3.3 (15 July 2005)
222 schoenebeck 686
223     * packaging changes:
224     - fixed compilation with gcc 4.0
225    
226 schoenebeck 687 * Gigasampler format engine:
227     - LFO preprocessing was performed even though the respective LFO was
228     disabled by the instrument patch (minor efficiency fix)
229 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
230     for volume ramp downs in the same fragment (needed for current voice
231     stealing implementation) then simply inform the user with a warning
232     about possible click sounds and reduce the volume ramp down
233     appropriately instead of cancelling the audio device connection
234 schoenebeck 687
235 schoenebeck 677 Version 0.3.2 (24 June 2005)
236 schoenebeck 609
237     * packaging changes:
238     - updated autotools build files to compile on OS X
239     (conditional compilation of CoreMIDI and MidiShare drivers)
240 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
241     './configure --disable-asm' (definitely not recommended)
242 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
243     - require automake (>= 1.5) for 'make -f Makefile.cvs'
244     (due to 'dist-bzip2' automake option)
245 schoenebeck 649
246     * Gigasampler format engine:
247     - support for the gig parameters for "release velocity response" curves
248     - fine tuning of the EGADSR envelope
249     - volume of release triggered samples now depends on note-on velocity,
250     note length and gig parameter "release trigger decay" instead of
251     note-off velocity.
252 schoenebeck 663 - revised voice stealing
253     (fixes crash and endless loop caused by voice stealing)
254 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
255 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
256     instead of when the respective voice is actually launched
257     (fixes undefined behavior if stolen voices belonged to a key group -
258     this case was followed by a "killed voice survived" error message)
259 schoenebeck 669 - fixed minor issue with null/silence samples
260     (those stole voices even though they don't need a voice at all which
261     resulted in "voice stealing didn't work out" messages)
262 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
263     instrument or audio output device change
264 schoenebeck 654
265 schoenebeck 620 * LSCP server:
266 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
267 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
268 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
269 schoenebeck 609
270 schoenebeck 668 * linuxsampler application:
271     - added command line parameters --lscp-addr and --lscp-port to override
272     default IP address and port of LSCP server
273    
274 schoenebeck 579 Version 0.3.1 (24 May 2005)
275    
276     * initial release
