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        - experimental support for running LinuxSampler as a DSSI, LV2 and
29          VST plugin
30    
31      * audio driver:
32        - removed the nonsense audio channel constraint (which was hard coded to
33          max. 100 audio channels) for most audio drivers
34        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
35          opposed to the LSCP specs
36        - bugfix: the SAMPLERATE parameter of some drivers (e.g. JACK)
37          reflected the wrong value
38        - fixed a memory management bug in ASIO driver
39        - Makefile fix: JACK_CFLAGS wasn't used
40        - JACK: use jack_client_open instead of the deprecated
41          jack_client_new
42    
43      * MIDI driver:
44        - added JACK MIDI driver
45        - dispatch bank select as ordinary CC as well, the user might seriously
46          want to (mis)use it for some purpose ("fixed" in all current MIDI
47          input drivers: ALSA, CoreMIDI, JACK, MidiShare, MME)
48    
49      * instruments database:
50        - avoid time consuming samples scanning when adding instruments
51          to the instruments database
52        - added support for handling lost files in the instruments database
53        - Implemented option for adding instruments in separate directories
54          in the instruments database
55          (patch by Chris Cherrett & Andrew Williams, a bit adjusted)
56    
57      * Gigasampler format engine:
58        - fixed a memory leak that could happen when a channel was deleted
59          while notes were playing
60        - made it possible to load an instrument even if the audio thread
61          isn't running
62        - added partial support for the "Controller Triggered" MIDI rule,
63          enough for piano gigs with pedal noise samples
64        - minor fix: only mark FX sends as being modified if really the
65          respective FX send MIDI controller was used
66        - added support for GM global device volume SysEx message
67          (can be selected at compile time to either apply globally to the
68          whole sampler [default] or only to the sampler channels that are
69          connected to the respective MIDI input port the SysEx message arrived
70          on)
71        - bugfix: notes triggered at position 0 in the audio buffer were
72          sometimes wrongly killed in the same buffer, causing no sound to
73          be played
74        - added support for chromatic / drumkit mode Roland GS Sysex message
75          which is usally used to switch a part between chromatic sounds and
76          drumkit sounds (as opposed to their common default setting of MIDI
77          part 10 being a drumkit part and all other ones chromatic parts), in
78          LS however one can switch between the first 16 MIDI instrument maps
79          defined for the sampler
80        - made it possible to create multiple sample channels even if the
81          audio thread isn't running
82    
83      * LSCP server:
84        - added new LSCP event "CHANNEL_MIDI" which can be used by frontends to
85          react on MIDI data arriving on certain sampler channels (so far only
86          Note-On and Note-Off events are sent via this LSCP event)
87        - added new LSCP event "DEVICE_MIDI" which can be used by frontends to
88          react on MIDI data arriving on certain MIDI input devices (so far only
89          Note-On and Note-Off events are sent via this LSCP event)
90        - added new LSCP commands: FIND LOST DB_INSTRUMENT_FILES and
91          SET DB_INSTRUMENT FILE_PATH
92        - added new LSCP command: SEND CHANNEL MIDI_DATA which can be used by
93          frontends to send MIDI messages to specific sampler channel
94        - added two additional fields to GET FILE INSTRUMENT INFO command -
95          KEY_BINDINGS and KEYSWITCH_BINDINGS
96        - bugfix: the bank number provided by MIDI_INSTRUMENT_INFO notifications
97          was incorrect
98        - Optimized the retrieval of the MIDI instrument mappings
99    
100      * Bug fixes:
101        - fixed a crash which occurs when removing a sampler channel waiting
102          to start instrument loading after another channel
103    
104    
105    Version 0.5.1 (6 December 2007)
106    
107      * packaging changes:
108        - added autoconf checks for pthread library
109        - added autoconf check for pthread bug found on certain NPTL-enabled
110          glibc versions (see Gentoo bug report #194076)
111        - added autoconf checks for MS Windows
112    
113      * general changes:
114        - bugfix: the thread used by an editor plugin didn't die when the
115          editor closed
116        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
117          out all the space. operator--() did not apply size_mask after
118          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
119          order to avoid problems with the _NonVolatileReader functions.
120        - bugfix: Stream.h: added a missing divide by BytesPerSample in
121          GetWriteSpace(). Since this function is currently only used in
122          the stream's qsort() compare function, it didn't trigger any
123          bugs.
124        - Resampler.h, Synthesizer.h: cubic interpolation now works in
125          24bit mode too. Faster method to read 24bit words on little
126          endian machines (x86): replaced 3 byte reads + shifts with a 1
127          unaligned 32bit read and shift
128        - experimental support for MS Windows (MIDI input via MME, AUDIO
129          output via ASIO)
130        - made handling of SIGINT signal (Ctrl-C) a bit more robust
131        - support for monitoring the total number of active disk streams
132          (new LSCP commands: GET TOTAL_STREAM_COUNT,
133          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
134    
135      * AUDIO driver:
136        - added Windows ASIO low latency audio driver
137    
138      * MIDI driver:
139        - added MME Windows MIDI driver
140    
141      * LSCP server:
142        - added support for Windows style path / filenames, however with
143          forward slash path separators instead of backslash
144          (i.e. "C:/foo/bar.gig")
145        - allow naughty liblscp to send non-string device parameters within
146          apostrophes as well
147        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
148          "LIST FILE INSTRUMENTS <file>" and
149          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
150          about an arbitrary instrument file on the system where the sampler is
151          running on
152    
153    Version 0.5.0 (15 October 2007)
