* added completely new XCode project files for Mac OSX which is now
  capable to execute our autoconf environment, thus no need anymore
  to maintain the compile time configuration file (osx/version.h) for
  OSX manually (patch by Toshi Nagata)

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