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        - fixes for building with newer MinGW versions
12        - fix for building with bison 2.4 (#111)
13    
14      * general changes:
15        - bugfix: on some POSIX systems instrument editor plugins refused to
16          load as we used a non-portable Linux specific struct field
17          (fixes bug #70, patch by Ronald Baljeu)
18        - fixed endless loop which occured when loading an instrument editor
19          plugin DLL on Windows systems failed
20        - fixed memory leaks that occurred when liblinuxsampler was unloaded
21        - optimized the SynchronizedConfig class so it doesn't wait
22          unnecessarily long after an update
23        - added support for notifying instrument editors on note-on / note-off
24          events (e.g. to highlight the pressed keys on the virtual keyboard
25          of gigedit)
26        - added support for triggering notes by instrument editors (see above)
27        - be verbose on DLL load errors (on Linux)
28        - fixed di-harmonic triangle LFO implementation (this LFO implementation
29          is only used by very few systems, most pick the int math
30          implementation, which is usually faster)
31        - fixes for audio drivers with varying buffer sizes
32        - experimental support for running LinuxSampler as a DSSI, LV2 and
33          VST plugin
34        - notification events for stream/voice count statistics are now sent
35          only when there are actual changes
36        - added memory ordering constraints to improve stability on
37          multi-core and multi-cpu systems
38        - maximum voices and disk streams can now be altered at runtime
39    
40      * audio driver:
41        - removed the nonsense audio channel constraint (which was hard coded to
42          max. 100 audio channels) for most audio drivers
43        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
44          opposed to the LSCP specs
45        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
46          reflected the wrong value
47        - fixed a memory management bug in ASIO driver
48        - Makefile fix: JACK_CFLAGS wasn't used
49        - JACK: use jack_client_open instead of the deprecated
50          jack_client_new
51    
52      * MIDI driver:
53        - added JACK MIDI driver
54        - dispatch bank select as ordinary CC as well, the user might seriously
55          want to (mis)use it for some purpose ("fixed" in all current MIDI
56          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
57    
58      * instruments database:
59        - avoid time consuming samples scanning when adding instruments
60          to the instruments database
61        - added support for handling lost files in the instruments database
62        - Implemented option for adding instruments in separate directories
63          in the instruments database
64          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
65    
66      * Gigasampler format engine:
67        - fixed a memory leak that could happen when a channel was deleted
68          while notes were playing
69        - made it possible to load an instrument even if the audio thread
70          isn't running
71        - added partial support for the "Controller Triggered" MIDI rule,
72          enough for piano gigs with pedal noise samples
73        - minor fix: only mark FX sends as being modified if really the
74          respective FX send MIDI controller was used
75        - added support for GM global device volume SysEx message
76          (can be selected at compile time to either apply globally to the
77          whole sampler [default] or only to the sampler channels that are
78          connected to the respective MIDI input port the SysEx message arrived
79          on)
80        - bugfix: notes triggered at position 0 in the audio buffer were
81          sometimes wrongly killed in the same buffer, causing no sound to
82          be played
83        - added support for chromatic / drumkit mode Roland GS Sysex message
84          which is usally used to switch a part between chromatic sounds and
85          drumkit sounds (as opposed to their common default setting of MIDI
86          part 10 being a drumkit part and all other ones chromatic parts), in
87          LS however one can switch between the first 16 MIDI instrument maps
88          defined for the sampler
89        - made it possible to create multiple sample channels even if the
90          audio thread isn't running
91    
92      * LSCP server:
93        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
94          react on MIDI data arriving on certain sampler channels (so far only
95          Note-On and Note-Off events are sent via this LSCP event)
96        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
97          react on MIDI data arriving on certain MIDI input devices (so far only
98          Note-On and Note-Off events are sent via this LSCP event)
99        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
100          SET DB_INSTRUMENT FILE_PATH
101        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
102          frontends to send MIDI messages to specific sampler channel
103        - added two additional fields to GET FILE INSTRUMENT INFO command -
104          KEY_BINDINGS and KEYSWITCH_BINDINGS
105        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
106          was incorrect
107        - Optimized the retrieval of the MIDI instrument mappings
108        - added new LSCP command "SET VOICES" to globally alter the maximum
109          amount of voices, added new LSCP event "GLOBAL_INFO:VOICES" which will
110          be triggered respectively
111        - added new LSCP command "SET STREAMS" to globally alter the maximum
112          amount of disk streams, added new LSCP event "GLOBAL_INFO:STREAMS"
113          which will be triggered respectively
114        - bugfix: retry if "select" returns EINTR (this fixes a crash when
115          a gigedit file dialog is opened)
116    
117      * Bug fixes:
118        - fixed a crash which occurs when removing a sampler channel waiting
119          to start instrument loading after another channel
120    
121    
122    Version 0.5.1 (6 December 2007)
123    
124      * packaging changes:
125        - added autoconf checks for pthread library
126        - added autoconf check for pthread bug found on certain NPTL-enabled
127          glibc versions (see Gentoo bug report #194076)
128        - added autoconf checks for MS Windows
129    
130      * general changes:
131        - bugfix: the thread used by an editor plugin didn't die when the
132          editor closed
133        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
134          out all the space. operator--() did not apply size_mask after
135          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
136          order to avoid problems with the _NonVolatileReader functions.
137        - bugfix: Stream.h: added a missing divide by BytesPerSample in
138          GetWriteSpace(). Since this function is currently only used in
139          the stream's qsort() compare function, it didn't trigger any
140          bugs.
141        - Resampler.h, Synthesizer.h: cubic interpolation now works in
142          24bit mode too. Faster method to read 24bit words on little
143          endian machines (x86): replaced 3 byte reads + shifts with a 1
144          unaligned 32bit read and shift
145        - experimental support for MS Windows (MIDI input via MME, AUDIO
146          output via ASIO)
147        - made handling of SIGINT signal (Ctrl-C) a bit more robust
148        - support for monitoring the total number of active disk streams
149          (new LSCP commands: GET TOTAL_STREAM_COUNT,
150          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
151    
152      * AUDIO driver:
153        - added Windows ASIO low latency audio driver
154    
155      * MIDI driver:
156        - added MME Windows MIDI driver
157    
158      * LSCP server:
159        - added support for Windows style path / filenames, however with
160          forward slash path separators instead of backslash
161          (i.e. "C:/foo/bar.gig")
162        - allow naughty liblscp to send non-string device parameters within
163          apostrophes as well
164        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
165          "LIST FILE INSTRUMENTS <file>" and
166          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
167          about an arbitrary instrument file on the system where the sampler is
168          running on
169

284        - parser now supports extended ASCII character set
285          (up to ASCII code 255, i.e. includes now umlauts and accents)
286        - filename arguments in LSCP commands now allow to use escape
287          sequences, that is directly literal as one of: \', \", \\, \n, \r,
288          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
289          code value like \xf2) (fixes bug #24)
290        - the following LSCP commands now also support escape sequences for at
291          least one of their text-based parameters (i.e. name, description):

299          occured, the unexpected character and the actually expected, possible
300          character(s), the latter only if less than 5 possibilities)
301        - made sure that LSCP syntax is not affected by gigedit locale
302          settings
303        - bugfix regarding strings parameter lists: all comma separated lists
304          of strings were treated as being one string containing commas
305          (fixes #57)

315          to the index of the port to which the sampler channel is connected.
316        - The previous bindings were not been disconnected when altering
317          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
318          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
319        - The active stream/voice count statistic was incorrect.
320        - notification events were not been sent for some sampler
321          channel changes
