* src/drivers/MidiInputPort.cpp: fixed legacy SysEx code which caused
  dispatching of MIDI SysEx messages several times instead of once
* src/engines/gig/Engine.cpp: fixed bug in SysEx handling
  (patch by Juan Linietsky)

1 persson 696 Version CVS HEAD (?)
2    
3 schoenebeck 697 * packaging changes:
4     - install necessary development header files for allowing 3rd party
5     applications to link against liblinuxsampler
6     - liblinuxsampler's API documentation can be generated with 'make docs'
7     (Doxygen required)
8 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
9     implementation (currently either an integer math solution or a
10     di-harmonic approximation), automatic detection can be overriden
11     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
12     configure script argument though (mandatory for cross-compilation)
13 schoenebeck 697
14 persson 696 * Gigasampler format engine:
15 schoenebeck 738 - extensive synthesis optimization
16     (reimplementation of EGs and LFO(s), removed synthesis parameter
17     prerendering and the synthesis parameter matrix in general, splitting
18     each audio fragment into subfragments now where each subfragment uses
19     constant synthesis parameters - that is volume, pitch and filter
20     coefficients)
21 persson 696 - fine tuning of the EG modulation parameters
22 persson 729 - improved filter cutoff calculation by adding support for the
23     following gig parameters: Cutoff freq (used when no cutoff
24     controller is defined), Control invert, Minimum cutoff, Velocity
25     curve and Velocity range. The keyboard tracking now also scales
26     cutoff frequency, not just resonance.
27 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
28 persson 696
29 schoenebeck 711 * LSCP server:
30     - fixed application exit on broken pipe error (fixes bug #20)
31    
32 schoenebeck 775 * MIDI driver:
33     - fixed legacy sysex code which caused dispatching of MIDI SysEx
34     messages several times instead of once
35    
36 schoenebeck 705 * general changes:
37     - support for muting sampler channels and solo mode of the same, two new
38     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
39     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
40     introduced for this, the behavior is the same like on a mixer console
41 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
42     --enable-process-muted-channels which can be used to enable the
43     processing of muted channels.
44 schoenebeck 705
45 schoenebeck 692 Version 0.3.3 (15 July 2005)
46 schoenebeck 686
47     * packaging changes:
48     - fixed compilation with gcc 4.0
49    
50 schoenebeck 687 * Gigasampler format engine:
51     - LFO preprocessing was performed even though the respective LFO was
52     disabled by the instrument patch (minor efficiency fix)
53 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
54     for volume ramp downs in the same fragment (needed for current voice
55     stealing implementation) then simply inform the user with a warning
56     about possible click sounds and reduce the volume ramp down
57     appropriately instead of cancelling the audio device connection
58 schoenebeck 687
59 schoenebeck 677 Version 0.3.2 (24 June 2005)
60 schoenebeck 609
61     * packaging changes:
62     - updated autotools build files to compile on OS X
63     (conditional compilation of CoreMIDI and MidiShare drivers)
64 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
65     './configure --disable-asm' (definitely not recommended)
66 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
67     - require automake (>= 1.5) for 'make -f Makefile.cvs'
68     (due to 'dist-bzip2' automake option)
69 schoenebeck 649
70     * Gigasampler format engine:
71     - support for the gig parameters for "release velocity response" curves
72     - fine tuning of the EGADSR envelope
73     - volume of release triggered samples now depends on note-on velocity,
74     note length and gig parameter "release trigger decay" instead of
75     note-off velocity.
76 schoenebeck 663 - revised voice stealing
77     (fixes crash and endless loop caused by voice stealing)
78 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
79 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
80     instead of when the respective voice is actually launched
81     (fixes undefined behavior if stolen voices belonged to a key group -
82     this case was followed by a "killed voice survived" error message)
83 schoenebeck 669 - fixed minor issue with null/silence samples
84     (those stole voices even though they don't need a voice at all which
85     resulted in "voice stealing didn't work out" messages)
86 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
87     instrument or audio output device change
88 schoenebeck 654
89 schoenebeck 620 * LSCP server:
90 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
91 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
92 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
93 schoenebeck 609
94 schoenebeck 668 * linuxsampler application:
95     - added command line parameters --lscp-addr and --lscp-port to override
96     default IP address and port of LSCP server
97    
98 schoenebeck 579 Version 0.3.1 (24 May 2005)
99    
100     * initial release
