* fixed compiler error when --enable-override-filter-type was
  supplied to the configure script (fixes #46)

1 schoenebeck 947 Version CVS HEAD (?)
2    
3 schoenebeck 1065 * packaging changes:
4     - only the API relevant header (and source) files will be exported to
5     the Doxygen API documentation (explicitly listed in Doxyfile.in)
6 schoenebeck 1175 - added completely new XCode project files for Mac OSX which is now
7     capable to execute our autoconf environment, thus no need anymore
8     to maintain the compile time configuration file (osx/version.h) for
9     OSX manually (patch by Toshi Nagata)
10 schoenebeck 1065
11 schoenebeck 947 * general changes:
12     - replaced the old, confusing MIDI program change mechanism by a
13     flexible MIDI instrument mapper which allows to map arbitrary
14 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
15 schoenebeck 947 (engine type, instrument file, file index) triplets which will be
16     loaded on the respective channel when such MIDI program change
17     messages arrive, beside that, each entry allows to define a life-time
18     strategy for the instrument, so the user can define whether the
19     instrument should i.e. be permanently loaded (to be able to switch
20     quickly among sounds) or i.e. loaded just on demand when the
21     respective program change arrives (to safe RAM space), as well as a
22     global volume factor for each entry, so the user can adjust the volume
23     dynamic of his mapped instrument collection without having to modify
24 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
25     MIDI instrument maps and assign each sampler channel individually
26     a certain map, so that i.e. separation of normal instruments and
27     drumkits is possible
28 iliev 1108 - new notification events for tracking changes to audio/MIDI devices,
29     MIDI instrument maps, MIDI instruments, FX sends, global volume.
30 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
31     due to a constant size RingBuffer FIFO which is now replaced by a
32     dynamic (unlimited) size std::list FIFO
33 schoenebeck 1001 - added FX sends, these allow to route audio signals to arbitrary audio
34     output channels for being processed by external effect processors
35     (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
36     controllers
37 schoenebeck 1005 - global (sampler wide) volume can now be controlled at runtime
38 iliev 1130 - Implemented new, improved notification system
39 schoenebeck 1149 - fixed compilation errors regarding OSX
40     (patch by Toshi Nagata)
41 iliev 1161 - implemented instruments database
42 schoenebeck 947
43     * MIDI driver:
44     - dispatch bank select (MSB and LSB) messages
45    
46 schoenebeck 1049 * audio driver:
47     - the ALSA audio output driver parameters now reflect the correct
48     parameter value ranges for the respective selected sound card
49     (patch by Till Wimmer, a bit fixed and extended)
50    
51 persson 951 * Gigasampler format engine:
52     - if a filter is used and EG2 finishes before EG1, let the voice
53     die when EG2 has finished (this fixes a problem with clicks and
54     voice starvation for some gigs)
55 persson 1038 - playback is no longer disabled during instrument loading
56     - all notes playing on a channel that changes its instrument keep
57     playing with the old instrument until they get a note off
58     command
59 persson 1039 - EG fix: a release value of zero could cause noises or crash
60 schoenebeck 1041 - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
61 persson 1046 - EG fine tuning: when attack is zero the EG starts at a level
62     above max sustain level, which means that there is a decay phase
63     even if sustain is 100%
64 persson 1147 - more EG fixes: the level could sometimes go below zero and cause
65     noises or crashes
66 schoenebeck 1149 - minor fix of EGDecay (patch by Toshi Nagata)
67 schoenebeck 1181 - fixed compiler error when --enable-override-filter-type was
68     supplied to the configure script (fixes #46)
69 persson 951
70 iliev 959 * Bug fixes:
71     - fixed crash occurring on certain LSCP scripts (Bug 39)
72 persson 1038 - another thread safety fix for lscp "load engine" and "set
73     channel audio output device"
74 iliev 959
75 schoenebeck 937 Version 0.4.0 (24 November 2006)
76 persson 696
77 schoenebeck 697 * packaging changes:
78 capela 868 - changed deprecated copyright attribute to license; added ldconfig
79     to post-(un)install steps; added devel package for liblinuxsampler;
80     to linuxsampler.spec (RPM)
81 schoenebeck 697 - install necessary development header files for allowing 3rd party
82     applications to link against liblinuxsampler
83     - liblinuxsampler's API documentation can be generated with 'make docs'
84     (Doxygen required)
85 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
86     implementation (currently either an integer math solution or a
87     di-harmonic approximation), automatic detection can be overriden
88     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
89     configure script argument though (mandatory for cross-compilation)
90 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
91     provided some on his own (as CXXFLAGS)
92 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
93     messages
94 schoenebeck 852 - added compile time options to allow disabling the various audio and
95     MIDI drivers
96 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
97     (patch by Ebrahim Mayat)
98 schoenebeck 697
99 persson 696 * Gigasampler format engine:
100 schoenebeck 738 - extensive synthesis optimization
101     (reimplementation of EGs and LFO(s), removed synthesis parameter
102     prerendering and the synthesis parameter matrix in general, splitting
103     each audio fragment into subfragments now where each subfragment uses
104 persson 830 constant pitch and filter coefficients. The volume coefficient is
105     linearly interpolated inside a subfragment, unless
106     --disable-interpolate-volume is set.)
107 persson 696 - fine tuning of the EG modulation parameters
108 persson 729 - improved filter cutoff calculation by adding support for the
109     following gig parameters: Cutoff freq (used when no cutoff
110     controller is defined), Control invert, Minimum cutoff, Velocity
111 persson 791 curve and Velocity range. The keyboard tracking now scales
112     cutoff frequency instead of resonance.
113 persson 877 - added support for gig parameter Resonance.
114 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
115 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
116     which can be overridden with --enable-global-attenuation
117 persson 783 - EG fixes: made the length of "attack hold" stage more
118     accurate. Release stage can now start before attack stage
119 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
120     time now has a minimal value to prevent clicks.
121 persson 799 - fixed pitch changes larger than one octave
122 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
123     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
124     all modes can be altered via standard GM messages, that is CC5 for
125     altering portamento time, CC65 for enabling / disabling portamento
126     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
127 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
128     parameter) and crossfade
129 persson 831 - added support for the "attenuation controller threshold" gig
130     parameter
131 persson 832 - added smoothing of volume changes caused by control change
132     messages
133 persson 865 - sample loop parameters are now taken from the DimensionRegion
134     instead of the wave chunk
135     - fixed keyswitching for v3 gigs with a number of keyswitch splits
136     not equal to a power of two
137 persson 877 - reimplementation of the filter algorithm. The new filter is more
138     accurate and supports all gig filter types, including bandreject
139     and lowpass turbo.
140 persson 903 - real support for 24 bit samples - samples are not truncated to
141     16 bits anymore
142     - support for aftertouch (channel pressure, not polyphonic
143     aftertouch)
144 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
145     amplifying from 0)
146 persson 696
147 schoenebeck 711 * LSCP server:
148     - fixed application exit on broken pipe error (fixes bug #20)
149 iliev 793 - fixed the notification messages delay due to lack of
150     network activity (fixes bug #26)
151 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
152     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
153 schoenebeck 711
154 schoenebeck 838 * audio driver:
155     - added aRts audio output driver (by no means RT safe)
156    
157 schoenebeck 775 * MIDI driver:
158     - fixed legacy sysex code which caused dispatching of MIDI SysEx
159     messages several times instead of once
160 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
161     for events (i.e. for offline rendering based MIDI drivers)
162 persson 922 - added checks for bad MIDI data
163 schoenebeck 775
164 schoenebeck 900 * linuxsampler application:
165     - show available sampler engine types on startup
166    
167 schoenebeck 705 * general changes:
168     - support for muting sampler channels and solo mode of the same, two new
169     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
170     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
171     introduced for this, the behavior is the same like on a mixer console
172 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
173     --enable-process-muted-channels which can be used to enable the
174     processing of muted channels.
175 iliev 777 - support for sostenuto pedal
176 iliev 779 - support for monitoring the total number of active voices
177 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
178     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
179 persson 835 - fixed some memory management errors
180 persson 841 - fixed some concurrency problems that could lead to crashes when
181     LSCP commands were executed
182 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
183     sampler channel (fixes bug #36)
184 schoenebeck 705
185 schoenebeck 692 Version 0.3.3 (15 July 2005)
186 schoenebeck 686
187     * packaging changes:
188     - fixed compilation with gcc 4.0
189    
190 schoenebeck 687 * Gigasampler format engine:
191     - LFO preprocessing was performed even though the respective LFO was
192     disabled by the instrument patch (minor efficiency fix)
193 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
194     for volume ramp downs in the same fragment (needed for current voice
195     stealing implementation) then simply inform the user with a warning
196     about possible click sounds and reduce the volume ramp down
197     appropriately instead of cancelling the audio device connection
198 schoenebeck 687
199 schoenebeck 677 Version 0.3.2 (24 June 2005)
200 schoenebeck 609
201     * packaging changes:
202     - updated autotools build files to compile on OS X
203     (conditional compilation of CoreMIDI and MidiShare drivers)
204 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
205     './configure --disable-asm' (definitely not recommended)
206 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
207     - require automake (>= 1.5) for 'make -f Makefile.cvs'
208     (due to 'dist-bzip2' automake option)
209 schoenebeck 649
210     * Gigasampler format engine:
211     - support for the gig parameters for "release velocity response" curves
212     - fine tuning of the EGADSR envelope
213     - volume of release triggered samples now depends on note-on velocity,
214     note length and gig parameter "release trigger decay" instead of
215     note-off velocity.
216 schoenebeck 663 - revised voice stealing
217     (fixes crash and endless loop caused by voice stealing)
218 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
219 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
220     instead of when the respective voice is actually launched
221     (fixes undefined behavior if stolen voices belonged to a key group -
222     this case was followed by a "killed voice survived" error message)
223 schoenebeck 669 - fixed minor issue with null/silence samples
224     (those stole voices even though they don't need a voice at all which
225     resulted in "voice stealing didn't work out" messages)
226 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
227     instrument or audio output device change
228 schoenebeck 654
229 schoenebeck 620 * LSCP server:
230 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
231 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
232 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
233 schoenebeck 609
234 schoenebeck 668 * linuxsampler application:
235     - added command line parameters --lscp-addr and --lscp-port to override
236     default IP address and port of LSCP server
237    
238 schoenebeck 579 Version 0.3.1 (24 May 2005)
239    
240     * initial release
