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