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    
7      * general changes:
8        - replaced the old, confusing MIDI program change mechanism by a
9          flexible MIDI instrument mapper which allows to map arbitrary
10          (MIDI bank, MIDI program) pairs with arbitrary
11          (engine type, instrument file, file index) triplets which will be
12          loaded on the respective channel when such MIDI program change
13          messages arrive, beside that, each entry allows to define a life-time
14          strategy for the instrument, so the user can define whether the
15          instrument should i.e. be permanently loaded (to be able to switch
16          quickly among sounds) or i.e. loaded just on demand when the
17          respective program change arrives (to safe RAM space), as well as a
18          global volume factor for each entry, so the user can adjust the volume
19          dynamic of his mapped instrument collection without having to modify
20          the instrument files, also one can manage arbitrary amount of such
21          MIDI instrument maps and assign each sampler channel individually
22          a certain map, so that i.e. separation of normal instruments and
23          drumkits is possible
24        - new notification events for tracking audio/MIDI device changes,
25          MIDI instrument map changes and MIDI instrument changes
26        - sampler was limited to load max. 200 instruments in the background
27          due to a constant size RingBuffer FIFO which is now replaced by a
28          dynamic (unlimited) size std::list FIFO
29        - added FX sends, these allow to route audio signals to arbitrary audio
30          output channels for being processed by external effect processors
31          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
32          controllers
33        - global (sampler wide) volume can now be controlled at runtime
34    
35      * MIDI driver:
36        - dispatch bank select (MSB and LSB) messages
37    
38      * audio driver:
39        - the ALSA audio output driver parameters now reflect the correct
40          parameter value ranges for the respective selected sound card
41          (patch by Till Wimmer, a bit fixed and extended)
42    
43      * Gigasampler format engine:
44        - if a filter is used and EG2 finishes before EG1, let the voice
45          die when EG2 has finished (this fixes a problem with clicks and
46          voice starvation for some gigs)
47        - playback is no longer disabled during instrument loading
48        - all notes playing on a channel that changes its instrument keep
49          playing with the old instrument until they get a note off
50          command
51        - EG fix: a release value of zero could cause noises or crash
52        - handle MIDI coarse tuning messages (MIDI RPN #0 MSB #2 LSB)
53        - EG fine tuning: when attack is zero the EG starts at a level
54          above max sustain level, which means that there is a decay phase
55          even if sustain is 100%
56    
57      * Bug fixes:
58        - fixed crash occurring on certain LSCP scripts (Bug 39)
59        - another thread safety fix for lscp "load engine" and "set
60          channel audio output device"
61    
62    Version 0.4.0 (24 November 2006)
63    
64      * packaging changes:
65        - changed deprecated copyright attribute to license; added ldconfig
66          to post-(un)install steps; added devel package for liblinuxsampler;
67          to linuxsampler.spec (RPM)
