1  Version CVS HEAD (?)  Version CVS HEAD (?)
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          (can be selected at compile time to either apply globally to the
63          whole sampler [default] or only to the sampler channels that are
64          connected to the respective MIDI input port the SysEx message arrived
65          on)
66        - bugfix: notes triggered at position 0 in the audio buffer were
67          sometimes wrongly killed in the same buffer, causing no sound to
68          be played
69        - added support for chromatic / drumkit mode Roland GS Sysex message
70          which is usally used to switch a part between chromatic sounds and
71          drumkit sounds (as opposed to their common default setting of MIDI
72          part 10 being a drumkit part and all other ones chromatic parts), in
73          LS however one can switch between the first 16 MIDI instrument maps
74          defined for the sampler
75    
76      * LSCP server:
77        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
78          react on MIDI data arriving on certain sampler channels (so far only
79          Note-On and Note-Off events are sent via this LSCP event)
80        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
81          react on MIDI data arriving on certain MIDI input devices (so far only
82          Note-On and Note-Off events are sent via this LSCP event)
83        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
84          SET DB_INSTRUMENT FILE_PATH
85        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
86          was incorrect
87        - Optimized the retrieval of the MIDI instrument mappings
88    
89      * Bug fixes:
90        - fixed a crash which occurs when removing a sampler channel waiting
91          to start instrument loading after another channel
92    
93    
94    Version 0.5.1 (6 December 2007)
95    
96      * packaging changes:
97        - added autoconf checks for pthread library
98        - added autoconf check for pthread bug found on certain NPTL-enabled
99          glibc versions (see Gentoo bug report #194076)
100        - added autoconf checks for MS Windows
101    
102      * general changes:
103        - bugfix: the thread used by an editor plugin didn't die when the
104          editor closed
105        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
106          out all the space. operator--() did not apply size_mask after
107          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
108          order to avoid problems with the _NonVolatileReader functions.
109        - bugfix: Stream.h: added a missing divide by BytesPerSample in
110          GetWriteSpace(). Since this function is currently only used in
111          the stream's qsort() compare function, it didn't trigger any
112          bugs.
113        - Resampler.h, Synthesizer.h: cubic interpolation now works in
114          24bit mode too. Faster method to read 24bit words on little
115          endian machines (x86): replaced 3 byte reads + shifts with a 1
116          unaligned 32bit read and shift
117        - experimental support for MS Windows (MIDI input via MME, AUDIO
118          output via ASIO)
119        - made handling of SIGINT signal (Ctrl-C) a bit more robust
120        - support for monitoring the total number of active disk streams
121          (new LSCP commands: GET TOTAL_STREAM_COUNT,
122          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
123    
124      * AUDIO driver:
125        - added Windows ASIO low latency audio driver
126    
127      * MIDI driver:
128        - added MME Windows MIDI driver
129    
130      * LSCP server:
131        - added support for Windows style path / filenames, however with
132          forward slash path separators instead of backslash
133          (i.e. "C:/foo/bar.gig")
134        - allow naughty liblscp to send non-string device parameters within
135          apostrophes as well
136        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
137          "LIST FILE INSTRUMENTS <file>" and
138          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
139          about an arbitrary instrument file on the system where the sampler is
140          running on
141    
142    Version 0.5.0 (15 October 2007)
