* fixed compile time error for old Bison versions
  (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)

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 schoenebeck 947
60     * MIDI driver:
61     - dispatch bank select (MSB and LSB) messages
62    
63 schoenebeck 1049 * audio driver:
64     - the ALSA audio output driver parameters now reflect the correct
65     parameter value ranges for the respective selected sound card
66     (patch by Till Wimmer, a bit fixed and extended)
67    
68 persson 951 * Gigasampler format engine:
69     - if a filter is used and EG2 finishes before EG1, let the voice
70     die when EG2 has finished (this fixes a problem with clicks and
71     voice starvation for some gigs)
72 persson 1038 - playback is no longer disabled during instrument loading
73     - all notes playing on a channel that changes its instrument keep
74     playing with the old instrument until they get a note off
75     command
76 persson 1039 - EG fix: a release value of zero could cause noises or crash
77 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
78 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
79     above max sustain level, which means that there is a decay phase
80     even if sustain is 100%
81 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
82     noises or crashes
83 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
84 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
85     supplied to the configure script (fixes #46)
86 persson 951
87 schoenebeck 1244 * LSCP server:
88     - fixed compile time error for old Bison versions
89     (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
90    
91 iliev 959 * Bug fixes:
92     - fixed crash occurring on certain LSCP scripts (Bug 39)
93 persson 1038 - another thread safety fix for lscp "load engine" and "set
94     channel audio output device"
95 iliev 959
96 schoenebeck 1221 * test cases:
97     - updated and fixed (haven't been touched in a while)
98    
99 schoenebeck 937 Version 0.4.0 (24 November 2006)
100 persson 696
101 schoenebeck 697 * packaging changes:
102 capela 868 - changed deprecated copyright attribute to license; added ldconfig
103     to post-(un)install steps; added devel package for liblinuxsampler;
104     to linuxsampler.spec (RPM)
105 schoenebeck 697 - install necessary development header files for allowing 3rd party
106     applications to link against liblinuxsampler
107     - liblinuxsampler's API documentation can be generated with 'make docs'
108     (Doxygen required)
109 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
110     implementation (currently either an integer math solution or a
111     di-harmonic approximation), automatic detection can be overriden
112     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
113     configure script argument though (mandatory for cross-compilation)
114 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
115     provided some on his own (as CXXFLAGS)
116 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
117     messages
118 schoenebeck 852 - added compile time options to allow disabling the various audio and
119     MIDI drivers
120 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
121     (patch by Ebrahim Mayat)
122 schoenebeck 697
123 persson 696 * Gigasampler format engine:
124 schoenebeck 738 - extensive synthesis optimization
125     (reimplementation of EGs and LFO(s), removed synthesis parameter
126     prerendering and the synthesis parameter matrix in general, splitting
127     each audio fragment into subfragments now where each subfragment uses
128 persson 830 constant pitch and filter coefficients. The volume coefficient is
129     linearly interpolated inside a subfragment, unless
130     --disable-interpolate-volume is set.)
131 persson 696 - fine tuning of the EG modulation parameters
132 persson 729 - improved filter cutoff calculation by adding support for the
133     following gig parameters: Cutoff freq (used when no cutoff
134     controller is defined), Control invert, Minimum cutoff, Velocity
135 persson 791 curve and Velocity range. The keyboard tracking now scales
136     cutoff frequency instead of resonance.
137 persson 877 - added support for gig parameter Resonance.
138 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
139 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
140     which can be overridden with --enable-global-attenuation
141 persson 783 - EG fixes: made the length of "attack hold" stage more
142     accurate. Release stage can now start before attack stage
143 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
144     time now has a minimal value to prevent clicks.
145 persson 799 - fixed pitch changes larger than one octave
146 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
147     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
148     all modes can be altered via standard GM messages, that is CC5 for
149     altering portamento time, CC65 for enabling / disabling portamento
150     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
151 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
152     parameter) and crossfade
153 persson 831 - added support for the "attenuation controller threshold" gig
154     parameter
155 persson 832 - added smoothing of volume changes caused by control change
156     messages
157 persson 865 - sample loop parameters are now taken from the DimensionRegion
158     instead of the wave chunk
159     - fixed keyswitching for v3 gigs with a number of keyswitch splits
160     not equal to a power of two
161 persson 877 - reimplementation of the filter algorithm. The new filter is more
162     accurate and supports all gig filter types, including bandreject
163     and lowpass turbo.
164 persson 903 - real support for 24 bit samples - samples are not truncated to
165     16 bits anymore
166     - support for aftertouch (channel pressure, not polyphonic
167     aftertouch)
168 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
169     amplifying from 0)
170 persson 696
171 schoenebeck 711 * LSCP server:
172     - fixed application exit on broken pipe error (fixes bug #20)
173 iliev 793 - fixed the notification messages delay due to lack of
174     network activity (fixes bug #26)
175 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
176     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
177 schoenebeck 711
178 schoenebeck 838 * audio driver:
179     - added aRts audio output driver (by no means RT safe)
180    
181 schoenebeck 775 * MIDI driver:
182     - fixed legacy sysex code which caused dispatching of MIDI SysEx
183     messages several times instead of once
184 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
185     for events (i.e. for offline rendering based MIDI drivers)
186 persson 922 - added checks for bad MIDI data
187 schoenebeck 775
188 schoenebeck 900 * linuxsampler application:
189     - show available sampler engine types on startup
190    
191 schoenebeck 705 * general changes:
192     - support for muting sampler channels and solo mode of the same, two new
193     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
194     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
195     introduced for this, the behavior is the same like on a mixer console
196 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
197     --enable-process-muted-channels which can be used to enable the
198     processing of muted channels.
199 iliev 777 - support for sostenuto pedal
200 iliev 779 - support for monitoring the total number of active voices
201 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
202     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
203 persson 835 - fixed some memory management errors
204 persson 841 - fixed some concurrency problems that could lead to crashes when
205     LSCP commands were executed
206 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
207     sampler channel (fixes bug #36)
208 schoenebeck 705
209 schoenebeck 692 Version 0.3.3 (15 July 2005)
210 schoenebeck 686
211     * packaging changes:
212     - fixed compilation with gcc 4.0
213    
214 schoenebeck 687 * Gigasampler format engine:
215     - LFO preprocessing was performed even though the respective LFO was
216     disabled by the instrument patch (minor efficiency fix)
217 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
218     for volume ramp downs in the same fragment (needed for current voice
219     stealing implementation) then simply inform the user with a warning
220     about possible click sounds and reduce the volume ramp down
221     appropriately instead of cancelling the audio device connection
222 schoenebeck 687
223 schoenebeck 677 Version 0.3.2 (24 June 2005)
224 schoenebeck 609
225     * packaging changes:
226     - updated autotools build files to compile on OS X
227     (conditional compilation of CoreMIDI and MidiShare drivers)
228 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
229     './configure --disable-asm' (definitely not recommended)
230 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
231     - require automake (>= 1.5) for 'make -f Makefile.cvs'
232     (due to 'dist-bzip2' automake option)
233 schoenebeck 649
234     * Gigasampler format engine:
235     - support for the gig parameters for "release velocity response" curves
236     - fine tuning of the EGADSR envelope
237     - volume of release triggered samples now depends on note-on velocity,
238     note length and gig parameter "release trigger decay" instead of
239     note-off velocity.
240 schoenebeck 663 - revised voice stealing
241     (fixes crash and endless loop caused by voice stealing)
242 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
243 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
244     instead of when the respective voice is actually launched
245     (fixes undefined behavior if stolen voices belonged to a key group -
246     this case was followed by a "killed voice survived" error message)
247 schoenebeck 669 - fixed minor issue with null/silence samples
248     (those stole voices even though they don't need a voice at all which
249     resulted in "voice stealing didn't work out" messages)
250 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
251     instrument or audio output device change
252 schoenebeck 654
253 schoenebeck 620 * LSCP server:
254 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
255 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
256 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
257 schoenebeck 609
258 schoenebeck 668 * linuxsampler application:
259     - added command line parameters --lscp-addr and --lscp-port to override
260     default IP address and port of LSCP server
261    
262 schoenebeck 579 Version 0.3.1 (24 May 2005)
263    
264     * initial release
