3    * packaging changes:    * packaging changes:
4        - fixed building with newer MinGW-w64
5    
6      * general changes:
7        - Refactoring: moved the independent code from
8          the Gigasampler format engine to base classes
9        - command line option '--profile' is currently disabled, since the
10          respective profiling code is currently broken
11        - Introduced support for optional environment variable
12          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
13          where the sampler shall look for instrument editor plugins
14          (patch by Luis Garrido, slightly modified).
15    
16      * Gigasampler format engine:
17        - implemented the "round robin keyboard" dimension
18        - fixed round robin and random dimensions for cases when number of
19          dimension zones is not a power of two
20        - made round robin use a counter for each region instead of each
21          key
22    
23      * SFZ format engine:
24        - Initial implementation (not usable yet)
25        - added support for v2 multiple stage envelope generators
26        - added a fine-tuned v1 envelope generator instead of using the
27          one from the gig engine
28        - fixed memory leak and memory handling errors
29        - added support for trigger=first, trigger=legato and sw_previous
30        - allow non-numerical key values ("C#4" for example)
31        - "key" opcode now sets pitch_keycenter too
32        - fixed error when unloading instrument with same sample used by
33          multiple regions
34        - added some opcode aliases, like loopmode for loop_mode, to be
35          more compatible
36        - added support for trigger=release and rt_decay
37        - added support for off_mode=normal
38        - added support for random, seq_position, seq_length and volume
39        - added v1 LFO opcodes to parser (no support in engine yet)
40        - added support for amp_veltrack and amp_velcurve_N
41        - fine-tuned the default velocity curve
42        - added support for transpose
43        - fixed crash when using sw_down/up
44        - improved logic for sw_lokey/hikey/up/down/last
45        - added more v1 aliases to parser
46        - reduced memory usage for sfz data
47        - RT-safeness: avoid malloc in audio thread
48        - fixed a bug that could cause voice stealing to fail
49    
50      * SoundFont format engine:
51        - Initial implementation (not usable yet)
52        - RT-safeness: avoid malloc in audio thread
53        - fixed a bug that could cause voice stealing to fail
54    
55      * Host plugins:
56        - AU bugfix: failed to destroy its audio/MIDI devices
57        - Listen to all interfaces on Mac OS X (INADDR_ANY)
58        - VST bugfix: If the host called resume() before and after
59          changing sample rate or block size, the number of channels was
60          incorrectly set to two. This caused silence in Cubase 5.
61    
62      * MIDI driver:
63        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
64          the ALSA sequencer client name
65    
66      * LSCP server:
67        - added support for sending MIDI CC messages via LSCP command
68          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

70      * Bug fixes:
71        - Fixed crash which may occur when MIDI key + transpose is out of range
72    
73    Version 1.0.0 (31 July 2009)
