2    
3      * plugin changes:
4        - LV2 Persist + Files support (patch by David Robillard)
5    
6      * packaging changes:
7        - fixed building with newer MinGW-w64
8    
9      * general changes:
10        - Refactoring: moved the independent code from
11          the Gigasampler format engine to base classes
12        - command line option '--profile' is currently disabled, since the
13          respective profiling code is currently broken
14        - Introduced support for optional environment variable
15          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
16          where the sampler shall look for instrument editor plugins
17          (patch by Luis Garrido, slightly modified).
18        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
19        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
20        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
21          note (in this implementation of the sampler its simply hard routed to
22          the 1st effect send of the sampler channel, no matter what the actual
23          effect type is)
24        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
25          note (in this implementation of the sampler its simply hard routed to
26          the 2nd effect send of the sampler channel, no matter what the actual
27          effect type is)
28        - implemented support for internal LADSPA effects
29        - raised limit of program change queue from 100 to 512
30          (as suggested by Alex Stone)
31    
32      * Gigasampler format engine:
33        - implemented the "round robin keyboard" dimension
34        - fixed round robin and random dimensions for cases when number of
35          dimension zones is not a power of two
36        - made round robin use a counter for each region instead of each
37          key
38    
39      * SFZ format engine:
40        - Initial implementation (not usable yet)
41        - added support for v2 multiple stage envelope generators
42        - added a fine-tuned v1 envelope generator instead of using the
43          one from the gig engine
44        - fixed memory leak and memory handling errors
45        - added support for trigger=first, trigger=legato and sw_previous
46        - allow non-numerical key values ("C#4" for example)
47        - "key" opcode now sets pitch_keycenter too
48        - fixed error when unloading instrument with same sample used by
49          multiple regions
50        - added some opcode aliases, like loopmode for loop_mode, to be
51          more compatible
52        - added support for trigger=release and rt_decay
53        - added support for off_mode=normal
54        - added support for random, seq_position, seq_length and volume
55        - added v1 LFO opcodes to parser (no support in engine yet)
56        - added support for amp_veltrack and amp_velcurve_N
57        - fine-tuned the default velocity curve
58        - added support for transpose
59        - fixed crash when using sw_down/up
60        - improved logic for sw_lokey/hikey/up/down/last
61        - added more v1 aliases to parser
62        - reduced memory usage for sfz data
63        - RT-safeness: avoid malloc in audio thread
64        - fixed a bug that could cause voice stealing to fail
65        - optimized sample lookup
66        - improved support for exclusive groups (group, off_by and
67          off_mode)
68        - added support for controller triggered regions (on_locc/on_hicc)
69        - added support for loop_mode=one_shot
70        - fixed playback of 16 bit wav files on big endian CPUs
71        - added support for Ogg Vorbis sample files
72        - use loop markers from sample file if loop_start and loop_end are
73          not set in sfz file
74    
75      * SoundFont format engine:
76        - Initial implementation (not usable yet)
77        - RT-safeness: avoid malloc in audio thread
78        - fixed a bug that could cause voice stealing to fail
79    
80      * Host plugins:
81        - AU bugfix: failed to destroy its audio/MIDI devices
82        - Listen to all interfaces on Mac OS X (INADDR_ANY)
83        - VST bugfix: If the host called resume() before and after
84          changing sample rate or block size, the number of channels was
85          incorrectly set to two. This caused silence in Cubase 5.
86        - save engine type (gig, sfz or sf2) in plugin state
87        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
88          64 bit Windows
89    
90      * MIDI driver:
91        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
92          the ALSA sequencer client name
93        - removed limit of maximum amount of MIDI ports per MIDI device, since
94          there is no reason for this limit
95

97        - added support for sending MIDI CC messages via LSCP command
98          "SEND CHANNEL MIDI_DATA CC <sampler-chan> <ctrl> <val>"

125          <effect-chain> <chain-pos>"
126        - added LSCP command "SET FX_SEND EFFECT <sampler_channel>
127          <fx_send_id> <effect_chain> <chain_pos>"
128        - added LSCP command "REMOVE FX_SEND EFFECT <sampler_channel> <fx_send_id>"
129    
130      * Bug fixes:

139        - bugfix: calling SET VOICES (which Fantasia does on start and
140          refresh) could cause instruments to be unloaded

261          the instruments DB file is located in
262          %USERPROFILE%\.linuxsampler\instruments.db which allows different
263          databases for each windows user
