1  Version CVS HEAD (?)  Version CVS HEAD (?)
2    
3      * general changes:
4        - bugfix: on some POSIX systems instrument editor plugins refused to
5          load as we used a non-portable Linux specific struct field
6          (fixes bug #70, patch by Ronald Baljeu)
7        - fixed endless loop which occured when loading an instrument editor
8          plugin DLL on Windows systems failed
9    
10      * audio driver:
11        - removed the nonsense audio channel constraint (which was hard coded to
12          max. 100 audio channels) for most audio drivers
13        - JACK audio driver did not offer a device parameter "SAMPLERATE" as
14          opposed to the LSCP specs
15    
16      * instruments database:
17        - avoid time consuming samples scanning when adding instruments
18          to the instruments database
19    
20    Version 0.5.1 (6 December 2007)
21    
22      * packaging changes:
23        - added autoconf checks for pthread library
24        - added autoconf check for pthread bug found on certain NPTL-enabled
25          glibc versions (see Gentoo bug report #194076)
26        - added autoconf checks for MS Windows
27    
28      * general changes:
29        - bugfix: the thread used by an editor plugin didn't die when the
30          editor closed
31        - bugfix: Ringbuffer.h: fill_write_space_with_null() did not zero
32          out all the space. operator--() did not apply size_mask after
33          decrementing the read_ptr. DEFAULT_WRAP_ELEMENTS set to 0 in
34          order to avoid problems with the _NonVolatileReader functions.
35        - bugfix: Stream.h: added a missing divide by BytesPerSample in
36          GetWriteSpace(). Since this function is currently only used in
37          the stream's qsort() compare function, it didn't trigger any
38          bugs.
39        - Resampler.h, Synthesizer.h: cubic interpolation now works in
40          24bit mode too. Faster method to read 24bit words on little
41          endian machines (x86): replaced 3 byte reads + shifts with a 1
42          unaligned 32bit read and shift
43        - experimental support for MS Windows (MIDI input via MME, AUDIO
44          output via ASIO)
45        - made handling of SIGINT signal (Ctrl-C) a bit more robust
46        - support for monitoring the total number of active disk streams
47          (new LSCP commands: GET TOTAL_STREAM_COUNT,
48          SUBSCRIBE TOTAL_STREAM_COUNT, UNSUBSCRIBE TOTAL_STREAM_COUNT)
49    
50      * AUDIO driver:
51        - added Windows ASIO low latency audio driver
52    
53      * MIDI driver:
54        - added MME Windows MIDI driver
55    
56      * LSCP server:
57        - added support for Windows style path / filenames, however with
58          forward slash path separators instead of backslash
59          (i.e. "C:/foo/bar.gig")
60        - allow naughty liblscp to send non-string device parameters within
61          apostrophes as well
62        - added new LSCP commands: "GET FILE INSTRUMENTS <file>",
63          "LIST FILE INSTRUMENTS <file>" and
64          "GET FILE INSTRUMENT INFO <file> <index>" for retrieving informations
65          about an arbitrary instrument file on the system where the sampler is
66          running on

83          are now in global_private.h

128        - added experimental code for synchronizing instrument editors hosted

143        - minor assembly fix in x86 features detection (don't use the PIC
144          register, to avoid relocations in the text segment at runtime)
145        - POSIX callback functions of Thread.h are hidden

176          127 (solo mode) only kill voices if the respective mode really
177          changed
178    
179      * LSCP server:
180        - fixed compile time error for old Bison versions
181          (i.e. v1.28 found on MacOS 10.4, patch by Toshi Nagata)
182        - parser now supports extended ASCII character set
183          (up to ASCII code 255, i.e. includes now umlauts and accents)
184        - filename arguments in LSCP commands now allow to use escape
185          sequences, that is directly literal as one of: \', \", \\, \n, \r,
186          \f, \t, \v, or as octal ASCII code value like \132, or as hex ASCII
187          code value like \xf2) (fixes bug #24)
188        - the following LSCP commands now also support escape sequences for at
189          least one of their text-based parameters (i.e. name, description):

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

210          on a sampler channel with connected MIDI device
211        - fixed a crash which occurs when changing the number of ports of a MIDI
212          device connected to a sampler channel to number less then or equal
213          to the index of the port to which the sampler channel is connected.
214        - The previous bindings were not been disconnected when altering
215          the ALSA_SEQ_BINDINGS parameter. Introduced a NONE keyword for
216          unsubscribing from all bindings (e.g. ALSA_SEQ_BINDINGS=NONE).
217        - The active stream/voice count statistic was incorrect.
218        - notification events were not been sent for some sampler
219          channel changes
