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    
37      * audio driver:
38        - removed the nonsense audio channel constraint (which was hard coded to
39          max. 100 audio channels) for most audio drivers
40        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
41          opposed to the LSCP specs
42        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
43          reflected the wrong value
44        - fixed a memory management bug in ASIO driver
45        - Makefile fix: JACK_CFLAGS wasn't used
46        - JACK: use jack_client_open instead of the deprecated
47          jack_client_new
48    
49      * MIDI driver:
50        - added JACK MIDI driver
51        - dispatch bank select as ordinary CC as well, the user might seriously
52          want to (mis)use it for some purpose ("fixed" in all current MIDI
53          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
54    
55      * instruments database:
56        - avoid time consuming samples scanning when adding instruments
57          to the instruments database
58        - added support for handling lost files in the instruments database
59        - Implemented option for adding instruments in separate directories
60          in the instruments database
61          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
62    
63      * Gigasampler format engine:
64        - fixed a memory leak that could happen when a channel was deleted
65          while notes were playing
66        - made it possible to load an instrument even if the audio thread
67          isn't running
68        - added partial support for the "Controller Triggered" MIDI rule,
69          enough for piano gigs with pedal noise samples
70        - minor fix: only mark FX sends as being modified if really the
71          respective FX send MIDI controller was used
72        - added support for GM global device volume SysEx message
73          (can be selected at compile time to either apply globally to the
74          whole sampler [default] or only to the sampler channels that are
75          connected to the respective MIDI input port the SysEx message arrived
76          on)
77        - bugfix: notes triggered at position 0 in the audio buffer were
78          sometimes wrongly killed in the same buffer, causing no sound to
79          be played
80        - added support for chromatic / drumkit mode Roland GS Sysex message
81          which is usally used to switch a part between chromatic sounds and
82          drumkit sounds (as opposed to their common default setting of MIDI
83          part 10 being a drumkit part and all other ones chromatic parts), in
84          LS however one can switch between the first 16 MIDI instrument maps
85          defined for the sampler
86        - made it possible to create multiple sample channels even if the
87          audio thread isn't running
88    
89      * LSCP server:
90        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
91          react on MIDI data arriving on certain sampler channels (so far only
92          Note-On and Note-Off events are sent via this LSCP event)
93        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
94          react on MIDI data arriving on certain MIDI input devices (so far only
95          Note-On and Note-Off events are sent via this LSCP event)
96        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
97          SET DB_INSTRUMENT FILE_PATH
98        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
99          frontends to send MIDI messages to specific sampler channel
100        - added two additional fields to GET FILE INSTRUMENT INFO command -
101          KEY_BINDINGS and KEYSWITCH_BINDINGS
102        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
103          was incorrect
104        - Optimized the retrieval of the MIDI instrument mappings
105    
106      * Bug fixes:
107        - fixed a crash which occurs when removing a sampler channel waiting
108          to start instrument loading after another channel
109    
110    
111    Version 0.5.1 (6 December 2007)
112    
113      * packaging changes:
114        - added autoconf checks for pthread library
115        - added autoconf check for pthread bug found on certain NPTL-enabled
116          glibc versions (see Gentoo bug report #194076)
117        - added autoconf checks for MS Windows
118    
119      * general changes:
120        - bugfix: the thread used by an editor plugin didn't die when the
121          editor closed
122        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
123          out all the space. operator--() did not apply size_mask after
124          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
125          order to avoid problems with the _NonVolatileReader functions.
126        - bugfix: Stream.h: added a missing divide by BytesPerSample in
127          GetWriteSpace(). Since this function is currently only used in
128          the stream's qsort() compare function, it didn't trigger any
129          bugs.
130        - Resampler.h, Synthesizer.h: cubic interpolation now works in
131          24bit mode too. Faster method to read 24bit words on little
132          endian machines (x86): replaced 3 byte reads + shifts with a 1
133          unaligned 32bit read and shift
134        - experimental support for MS Windows (MIDI input via MME, AUDIO
135          output via ASIO)
136        - made handling of SIGINT signal (Ctrl-C) a bit more robust
137        - support for monitoring the total number of active disk streams
138          (new LSCP commands: GET TOTAL_STREAM_COUNT,
139          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
140    
141      * AUDIO driver:
142        - added Windows ASIO low latency audio driver
143    
144      * MIDI driver:
145        - added MME Windows MIDI driver
146    
147      * LSCP server:
148        - added support for Windows style path / filenames, however with
149          forward slash path separators instead of backslash
150          (i.e. "C:/foo/bar.gig")
151        - allow naughty liblscp to send non-string device parameters within
152          apostrophes as well
153        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
154          "LIST FILE INSTRUMENTS <file>" and
155          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
156          about an arbitrary instrument file on the system where the sampler is
157          running on
158

291          settings
292        - bugfix regarding strings parameter lists: all comma separated lists
293          of strings were treated as being one string containing commas

304          to the index of the port to which the sampler channel is connected.
305        - The previous bindings were not been disconnected when altering
306          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
