2    
3    * packaging changes:    * packaging changes:
4        - autoconf bugfix: the PKG_CONFIG variable wasn't initialized properly,
5          causing e.g. the libgig test to fail when
6          "./configure --disable-jack-driver" was used
7          (patch by Alexis Ballier)
8        - fixed compilation with gcc 4.3
9        - fixes for building on OS X (thanks to Ebrahim Mayat for testing)
10        - fixed configure so it detects x86_64 (#107)
11    
12      * general changes:
13        - bugfix: on some POSIX systems instrument editor plugins refused to
14          load as we used a non-portable Linux specific struct field
15          (fixes bug #70, patch by Ronald Baljeu)
16        - fixed endless loop which occured when loading an instrument editor
17          plugin DLL on Windows systems failed
18        - fixed memory leaks that occurred when liblinuxsampler was unloaded
19        - optimized the SynchronizedConfig class so it doesn't wait
20          unnecessarily long after an update
21        - added support for notifying instrument editors on note-on / note-off
22          events (e.g. to highlight the pressed keys on the virtual keyboard
23          of gigedit)
24        - added support for triggering notes by instrument editors (see above)
25        - be verbose on DLL load errors (on Linux)
26        - fixed di-harmonic triangle LFO implementation (this LFO implementation
27          is only used by very few systems, most pick the int math
28          implementation, which is usually faster)
29        - fixes for audio drivers with varying buffer sizes
30        - experimental support for running LinuxSampler as a DSSI, LV2 and
31          VST plugin
32        - notification events for stream/voice count statistics are now sent
33          only when there are actual changes
34        - added memory ordering constraints to improve stability on
35          multi-core and multi-cpu systems
36        - maximum voices and disk streams can now be altered at runtime
37    
38      * audio driver:
39        - removed the nonsense audio channel constraint (which was hard coded to
40          max. 100 audio channels) for most audio drivers
41        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
42          opposed to the LSCP specs
43        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
44          reflected the wrong value
45        - fixed a memory management bug in ASIO driver
46        - Makefile fix: JACK_CFLAGS wasn't used
47        - JACK: use jack_client_open instead of the deprecated
48          jack_client_new
49    
50      * MIDI driver:
51        - added JACK MIDI driver
52        - dispatch bank select as ordinary CC as well, the user might seriously
53          want to (mis)use it for some purpose ("fixed" in all current MIDI
54          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
55    
56      * instruments database:
57        - avoid time consuming samples scanning when adding instruments
58          to the instruments database
59        - added support for handling lost files in the instruments database
60        - Implemented option for adding instruments in separate directories
61          in the instruments database
62          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
63    
64      * Gigasampler format engine:
65        - fixed a memory leak that could happen when a channel was deleted
66          while notes were playing
67        - made it possible to load an instrument even if the audio thread
68          isn't running
69        - added partial support for the "Controller Triggered" MIDI rule,
70          enough for piano gigs with pedal noise samples
71        - minor fix: only mark FX sends as being modified if really the
72          respective FX send MIDI controller was used
73        - added support for GM global device volume SysEx message
74          (can be selected at compile time to either apply globally to the
75          whole sampler [default] or only to the sampler channels that are
76          connected to the respective MIDI input port the SysEx message arrived
77          on)
78        - bugfix: notes triggered at position 0 in the audio buffer were
79          sometimes wrongly killed in the same buffer, causing no sound to
80          be played
81        - added support for chromatic / drumkit mode Roland GS Sysex message
82          which is usally used to switch a part between chromatic sounds and
83          drumkit sounds (as opposed to their common default setting of MIDI
84          part 10 being a drumkit part and all other ones chromatic parts), in
85          LS however one can switch between the first 16 MIDI instrument maps
86          defined for the sampler
87        - made it possible to create multiple sample channels even if the
88          audio thread isn't running
89    
90      * LSCP server:
91        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
92          react on MIDI data arriving on certain sampler channels (so far only
93          Note-On and Note-Off events are sent via this LSCP event)
94        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
95          react on MIDI data arriving on certain MIDI input devices (so far only
96          Note-On and Note-Off events are sent via this LSCP event)
97        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
98          SET DB_INSTRUMENT FILE_PATH
99        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
100          frontends to send MIDI messages to specific sampler channel
101        - added two additional fields to GET FILE INSTRUMENT INFO command -
102          KEY_BINDINGS and KEYSWITCH_BINDINGS
103        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
104          was incorrect
105        - Optimized the retrieval of the MIDI instrument mappings
106        - added new LSCP command "SET VOICES" to globally alter the maximum
107          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
108          be triggered respectively
109        - added new LSCP command "SET STREAMS" to globally alter the maximum
110          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
111          which will be triggered respectively
112    
113      * Bug fixes:
114        - fixed a crash which occurs when removing a sampler channel waiting
115          to start instrument loading after another channel
116    
117    
118    Version 0.5.1 (6 December 2007)
119    
120      * packaging changes:
121        - added autoconf checks for pthread library
122        - added autoconf check for pthread bug found on certain NPTL-enabled
123          glibc versions (see Gentoo bug report #194076)
124        - added autoconf checks for MS Windows
125    
126      * general changes:
127        - bugfix: the thread used by an editor plugin didn't die when the
128          editor closed
129        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
130          out all the space. operator--() did not apply size_mask after
131          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
132          order to avoid problems with the _NonVolatileReader functions.
133        - bugfix: Stream.h: added a missing divide by BytesPerSample in
134          GetWriteSpace(). Since this function is currently only used in
135          the stream's qsort() compare function, it didn't trigger any
136          bugs.
137        - Resampler.h, Synthesizer.h: cubic interpolation now works in
138          24bit mode too. Faster method to read 24bit words on little
139          endian machines (x86): replaced 3 byte reads + shifts with a 1
140          unaligned 32bit read and shift
141        - experimental support for MS Windows (MIDI input via MME, AUDIO
142          output via ASIO)
143        - made handling of SIGINT signal (Ctrl-C) a bit more robust
144        - support for monitoring the total number of active disk streams
145          (new LSCP commands: GET TOTAL_STREAM_COUNT,
146          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
147    
148      * AUDIO driver:
149        - added Windows ASIO low latency audio driver
150    
151      * MIDI driver:
152        - added MME Windows MIDI driver
153    
154      * LSCP server:
155        - added support for Windows style path / filenames, however with
156          forward slash path separators instead of backslash
157          (i.e. "C:/foo/bar.gig")
158        - allow naughty liblscp to send non-string device parameters within
159          apostrophes as well
160        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
161          "LIST FILE INSTRUMENTS <file>" and
162          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
163          about an arbitrary instrument file on the system where the sampler is
164          running on
165
