3    * packaging changes:    * packaging changes:
4        - config.h is not going to be installed along with liblinuxsampler's
5          API header files anymore
6        - only the API relevant header (and source) files will be exported to
7          the Doxygen API documentation (explicitly listed in Doxyfile.in)
8        - 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    
13      * general changes:
14        - replaced the old, confusing MIDI program change mechanism by a
15          flexible MIDI instrument mapper which allows to map arbitrary
16          (MIDI bank, MIDI program) pairs with arbitrary
17          (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          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        - new notification events for tracking changes to audio/MIDI devices,
31          MIDI instrument maps, MIDI instruments, FX sends, global volume.
32        - 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        - 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        - global (sampler wide) volume can now be controlled at runtime
40        - Implemented new, improved notification system
41        - fixed compilation errors regarding OSX
42          (patch by Toshi Nagata)
43        - implemented instruments database
44        - 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    
52      * MIDI driver:
53        - dispatch bank select (MSB and LSB) messages
54    
55      * 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      * 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        - 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        - EG fix: a release value of zero could cause noises or crash
69        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
70        - 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        - more EG fixes: the level could sometimes go below zero and cause
74          noises or crashes
75        - minor fix of EGDecay (patch by Toshi Nagata)
76        - fixed compiler error when --enable-override-filter-type was
77          supplied to the configure script (fixes #46)
78    
79      * Bug fixes:
80        - fixed crash occurring on certain LSCP scripts (Bug 39)
81        - another thread safety fix for lscp "load engine" and "set
82          channel audio output device"
83    
84    Version 0.4.0 (24 November 2006)
85    
86      * packaging changes:
87        - changed deprecated copyright attribute to license; added ldconfig
88          to post-(un)install steps; added devel package for liblinuxsampler;
89          to linuxsampler.spec (RPM)
