3    * packaging changes:    * 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        - 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    
11      * general changes:
12        - replaced the old, confusing MIDI program change mechanism by a
13          flexible MIDI instrument mapper which allows to map arbitrary
14          (MIDI bank, MIDI program) pairs with arbitrary
15          (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          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        - new notification events for tracking changes to audio/MIDI devices,
29          MIDI instrument maps, MIDI instruments, FX sends, global volume.
30        - 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        - 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        - global (sampler wide) volume can now be controlled at runtime
38        - Implemented new, improved notification system
39        - fixed compilation errors regarding OSX
40          (patch by Toshi Nagata)
41        - implemented instruments database
42    
43      * MIDI driver:
44        - dispatch bank select (MSB and LSB) messages
45    
46      * 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      * 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        - 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        - EG fix: a release value of zero could cause noises or crash
60        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
61        - 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        - more EG fixes: the level could sometimes go below zero and cause
65          noises or crashes
66        - minor fix of EGDecay (patch by Toshi Nagata)
67    
68      * Bug fixes:
69        - fixed crash occurring on certain LSCP scripts (Bug 39)
70        - another thread safety fix for lscp "load engine" and "set
71          channel audio output device"
72    
73    Version 0.4.0 (24 November 2006)
74    
75      * packaging changes:
76        - 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      - install necessary development header files for allowing 3rd party      - install necessary development header files for allowing 3rd party

111        - added support for gig parameter Resonance.
112      - fixed bug in sysex handling (patch by Juan Linietsky)      - fixed bug in sysex handling (patch by Juan Linietsky)
113        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
114          which can be overridden with --enable-global-attenuation
115        - EG fixes: made the length of "attack hold" stage more
116          accurate. Release stage can now start before attack stage
117          ends. Cancel release didn't work when sustain was zero. Attack
118          time now has a minimal value to prevent clicks.
119        - fixed pitch changes larger than one octave
120        - 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        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
126          parameter) and crossfade
127        - added support for the "attenuation controller threshold" gig
128          parameter
129        - added smoothing of volume changes caused by control change
130          messages
131        - 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        - 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        - 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        - LFO1 behaviour fixed (dampening from max volume instead of
143          amplifying from 0)
144    
145    * LSCP server:    * LSCP server:
146      - fixed application exit on broken pipe error (fixes bug #20)      - fixed application exit on broken pipe error (fixes bug #20)
147        - fixed the notification messages delay due to lack of
148          network activity (fixes bug #26)
149        - 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    
152      * audio driver:
153        - added aRts audio output driver (by no means RT safe)
154    
155    * MIDI driver:    * MIDI driver:

158        - API extension for MIDI drivers which already supply exact time stamps
159          for events (i.e. for offline rendering based MIDI drivers)
160        - added checks for bad MIDI data
161    
162      * linuxsampler application:
163        - show available sampler engine types on startup

176          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
177        - fixed some memory management errors
178        - fixed some concurrency problems that could lead to crashes when
179          LSCP commands were executed
