* added highly experimental support for on-the-fly instrument editing
  within the sampler's process (by using instrument editor plugins),
  you'll notice the new "Registered instrument editors:" message on
  startup, the plugin path can be overridden at compile time with
  ./configure --enable-plugin-dir=/some/dir
* added a new LSCP command "EDIT INSTRUMENT <sampler-channel>" to spawn
  a matching instrument editor for the instrument on the given sampler
  channel (LSCP command syntax might be subject to change soon)
* config.h is not going to be installed along with liblinuxsampler's
  API header files anymore (not necessary anymore)
* take care of $(DESTDIR) when creating the instruments DB on 'make
  install' rule (needed for packaging and cross compilation)
* bumped version to 0.4.0.5cvs

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 947
52     * MIDI driver:
53     - dispatch bank select (MSB and LSB) messages
54    
55 schoenebeck 1049 * audio driver:
56     - the ALSA audio output driver parameters now reflect the correct
57     parameter value ranges for the respective selected sound card
58     (patch by Till Wimmer, a bit fixed and extended)
59    
60 persson 951 * Gigasampler format engine:
61     - if a filter is used and EG2 finishes before EG1, let the voice
62     die when EG2 has finished (this fixes a problem with clicks and
63     voice starvation for some gigs)
64 persson 1038 - playback is no longer disabled during instrument loading
65     - all notes playing on a channel that changes its instrument keep
66     playing with the old instrument until they get a note off
67     command
68 persson 1039 - EG fix: a release value of zero could cause noises or crash
69 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
70 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
71     above max sustain level, which means that there is a decay phase
72     even if sustain is 100%
73 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
74     noises or crashes
75 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
76 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
77     supplied to the configure script (fixes #46)
78 persson 951
79 iliev 959 * Bug fixes:
80     - fixed crash occurring on certain LSCP scripts (Bug 39)
81 persson 1038 - another thread safety fix for lscp "load engine" and "set
82     channel audio output device"
83 iliev 959
84 schoenebeck 937 Version 0.4.0 (24 November 2006)
85 persson 696
86 schoenebeck 697 * packaging changes:
87 capela 868 - changed deprecated copyright attribute to license; added ldconfig
88     to post-(un)install steps; added devel package for liblinuxsampler;
89     to linuxsampler.spec (RPM)
90 schoenebeck 697 - install necessary development header files for allowing 3rd party
91     applications to link against liblinuxsampler
92     - liblinuxsampler's API documentation can be generated with 'make docs'
93     (Doxygen required)
94 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
95     implementation (currently either an integer math solution or a
96     di-harmonic approximation), automatic detection can be overriden
97     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
98     configure script argument though (mandatory for cross-compilation)
99 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
100     provided some on his own (as CXXFLAGS)
101 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
102     messages
103 schoenebeck 852 - added compile time options to allow disabling the various audio and
104     MIDI drivers
105 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
106     (patch by Ebrahim Mayat)
107 schoenebeck 697
108 persson 696 * Gigasampler format engine:
109 schoenebeck 738 - extensive synthesis optimization
110     (reimplementation of EGs and LFO(s), removed synthesis parameter
111     prerendering and the synthesis parameter matrix in general, splitting
112     each audio fragment into subfragments now where each subfragment uses
113 persson 830 constant pitch and filter coefficients. The volume coefficient is
114     linearly interpolated inside a subfragment, unless
115     --disable-interpolate-volume is set.)
116 persson 696 - fine tuning of the EG modulation parameters
117 persson 729 - improved filter cutoff calculation by adding support for the
118     following gig parameters: Cutoff freq (used when no cutoff
119     controller is defined), Control invert, Minimum cutoff, Velocity
120 persson 791 curve and Velocity range. The keyboard tracking now scales
121     cutoff frequency instead of resonance.
122 persson 877 - added support for gig parameter Resonance.
123 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
124 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
125     which can be overridden with --enable-global-attenuation
126 persson 783 - EG fixes: made the length of "attack hold" stage more
127     accurate. Release stage can now start before attack stage
128 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
129     time now has a minimal value to prevent clicks.
130 persson 799 - fixed pitch changes larger than one octave
131 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
132     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
133     all modes can be altered via standard GM messages, that is CC5 for
134     altering portamento time, CC65 for enabling / disabling portamento
135     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
136 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
137     parameter) and crossfade
138 persson 831 - added support for the "attenuation controller threshold" gig
139     parameter
140 persson 832 - added smoothing of volume changes caused by control change
141     messages
142 persson 865 - sample loop parameters are now taken from the DimensionRegion
143     instead of the wave chunk
144     - fixed keyswitching for v3 gigs with a number of keyswitch splits
145     not equal to a power of two
146 persson 877 - reimplementation of the filter algorithm. The new filter is more
147     accurate and supports all gig filter types, including bandreject
148     and lowpass turbo.
149 persson 903 - real support for 24 bit samples - samples are not truncated to
150     16 bits anymore
151     - support for aftertouch (channel pressure, not polyphonic
152     aftertouch)
153 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
154     amplifying from 0)
155 persson 696
156 schoenebeck 711 * LSCP server:
157     - fixed application exit on broken pipe error (fixes bug #20)
158 iliev 793 - fixed the notification messages delay due to lack of
159     network activity (fixes bug #26)
160 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
161     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
162 schoenebeck 711
163 schoenebeck 838 * audio driver:
164     - added aRts audio output driver (by no means RT safe)
165    
166 schoenebeck 775 * MIDI driver:
167     - fixed legacy sysex code which caused dispatching of MIDI SysEx
168     messages several times instead of once
169 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
170     for events (i.e. for offline rendering based MIDI drivers)
171 persson 922 - added checks for bad MIDI data
172 schoenebeck 775
173 schoenebeck 900 * linuxsampler application:
174     - show available sampler engine types on startup
175    
176 schoenebeck 705 * general changes:
177     - support for muting sampler channels and solo mode of the same, two new
178     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
179     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
180     introduced for this, the behavior is the same like on a mixer console
181 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
182     --enable-process-muted-channels which can be used to enable the
183     processing of muted channels.
184 iliev 777 - support for sostenuto pedal
185 iliev 779 - support for monitoring the total number of active voices
186 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
187     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
188 persson 835 - fixed some memory management errors
189 persson 841 - fixed some concurrency problems that could lead to crashes when
190     LSCP commands were executed
191 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
192     sampler channel (fixes bug #36)
193 schoenebeck 705
194 schoenebeck 692 Version 0.3.3 (15 July 2005)
195 schoenebeck 686
196     * packaging changes:
197     - fixed compilation with gcc 4.0
198    
199 schoenebeck 687 * Gigasampler format engine:
200     - LFO preprocessing was performed even though the respective LFO was
201     disabled by the instrument patch (minor efficiency fix)
202 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
203     for volume ramp downs in the same fragment (needed for current voice
204     stealing implementation) then simply inform the user with a warning
205     about possible click sounds and reduce the volume ramp down
206     appropriately instead of cancelling the audio device connection
207 schoenebeck 687
208 schoenebeck 677 Version 0.3.2 (24 June 2005)
209 schoenebeck 609
210     * packaging changes:
211     - updated autotools build files to compile on OS X
212     (conditional compilation of CoreMIDI and MidiShare drivers)
213 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
214     './configure --disable-asm' (definitely not recommended)
215 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
216     - require automake (>= 1.5) for 'make -f Makefile.cvs'
217     (due to 'dist-bzip2' automake option)
218 schoenebeck 649
219     * Gigasampler format engine:
220     - support for the gig parameters for "release velocity response" curves
221     - fine tuning of the EGADSR envelope
222     - volume of release triggered samples now depends on note-on velocity,
223     note length and gig parameter "release trigger decay" instead of
224     note-off velocity.
225 schoenebeck 663 - revised voice stealing
226     (fixes crash and endless loop caused by voice stealing)
227 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
228 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
229     instead of when the respective voice is actually launched
230     (fixes undefined behavior if stolen voices belonged to a key group -
231     this case was followed by a "killed voice survived" error message)
232 schoenebeck 669 - fixed minor issue with null/silence samples
233     (those stole voices even though they don't need a voice at all which
234     resulted in "voice stealing didn't work out" messages)
235 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
236     instrument or audio output device change
237 schoenebeck 654
238 schoenebeck 620 * LSCP server:
239 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
240 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
241 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
242 schoenebeck 609
243 schoenebeck 668 * linuxsampler application:
244     - added command line parameters --lscp-addr and --lscp-port to override
245     default IP address and port of LSCP server
246    
247 schoenebeck 579 Version 0.3.1 (24 May 2005)
248    
249     * initial release
