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