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

240    
241      * LSCP server:
242        - fixed compile time error for old Bison versions
243          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
244        - parser now supports extended ASCII character set
245          (up to ASCII code 255, i.e. includes now umlauts and accents)
246        - filename arguments in LSCP commands now allow to use escape
247          sequences, that is directly literal as one of: \', \", \\, \n, \r,
248          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
249          code value like \xf2) (fixes bug #24)
250        - the following LSCP commands now also support escape sequences for at
251          least one of their text-based parameters (i.e. name, description):

259          occured, the unexpected character and the actually expected, possible
260          character(s), the latter only if less than 5 possibilities)
261        - made sure that LSCP syntax is not affected by gigedit locale
262          settings
263        - bugfix regarding strings parameter lists: all comma separated lists
264          of strings were treated as being one string containing commas

275          to the index of the port to which the sampler channel is connected.
276        - The previous bindings were not been disconnected when altering
277          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
278          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
279        - The active stream/voice count statistic was incorrect.
280        - notification events were not been sent for some sampler
