* fixed some memory management errors

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 829 - do not automatically pick optimized gcc flags if the user already
14     provided some on his own (as CXXFLAGS)
15 schoenebeck 697
16 persson 696 * Gigasampler format engine:
17 schoenebeck 738 - extensive synthesis optimization
18     (reimplementation of EGs and LFO(s), removed synthesis parameter
19     prerendering and the synthesis parameter matrix in general, splitting
20     each audio fragment into subfragments now where each subfragment uses
21 persson 830 constant pitch and filter coefficients. The volume coefficient is
22     linearly interpolated inside a subfragment, unless
23     --disable-interpolate-volume is set.)
24 persson 696 - fine tuning of the EG modulation parameters
25 persson 729 - improved filter cutoff calculation by adding support for the
26     following gig parameters: Cutoff freq (used when no cutoff
27     controller is defined), Control invert, Minimum cutoff, Velocity
28 persson 791 curve and Velocity range. The keyboard tracking now scales
29     cutoff frequency instead of resonance.
30     - filter fine tuning: calculation of cutoff frequency and
31     bandwidth improved. Removed use of "BasicBPFilter". Changed
32     bandpass filter from constant peak to constant skirt. Added
33     support for gig parameter Resonance.
34 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
35 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
36     which can be overridden with --enable-global-attenuation
37 persson 783 - EG fixes: made the length of "attack hold" stage more
38     accurate. Release stage can now start before attack stage
39 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
40     time now has a minimal value to prevent clicks.
41 persson 799 - fixed pitch changes larger than one octave
42 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
43     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
44     all modes can be altered via standard GM messages, that is CC5 for
45     altering portamento time, CC65 for enabling / disabling portamento
46     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
47 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
48     parameter) and crossfade
49 persson 831 - added support for the "attenuation controller threshold" gig
50     parameter
51 persson 832 - added smoothing of volume changes caused by control change
52     messages
53 persson 696
54 schoenebeck 711 * LSCP server:
55     - fixed application exit on broken pipe error (fixes bug #20)
56 iliev 793 - fixed the notification messages delay due to lack of
57     network activity (fixes bug #26)
58 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
59     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
60 schoenebeck 711
61 schoenebeck 775 * MIDI driver:
62     - fixed legacy sysex code which caused dispatching of MIDI SysEx
63     messages several times instead of once
64    
65 schoenebeck 705 * general changes:
66     - support for muting sampler channels and solo mode of the same, two new
67     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
68     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
69     introduced for this, the behavior is the same like on a mixer console
70 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
71     --enable-process-muted-channels which can be used to enable the
72     processing of muted channels.
73 iliev 777 - support for sostenuto pedal
74 iliev 779 - support for monitoring the total number of active voices
75 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
76     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
77 persson 835 - fixed some memory management errors
78 schoenebeck 705
79 schoenebeck 692 Version 0.3.3 (15 July 2005)
80 schoenebeck 686
81     * packaging changes:
82     - fixed compilation with gcc 4.0
83    
84 schoenebeck 687 * Gigasampler format engine:
85     - LFO preprocessing was performed even though the respective LFO was
86     disabled by the instrument patch (minor efficiency fix)
87 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
88     for volume ramp downs in the same fragment (needed for current voice
89     stealing implementation) then simply inform the user with a warning
90     about possible click sounds and reduce the volume ramp down
91     appropriately instead of cancelling the audio device connection
92 schoenebeck 687
93 schoenebeck 677 Version 0.3.2 (24 June 2005)
94 schoenebeck 609
95     * packaging changes:
96     - updated autotools build files to compile on OS X
97     (conditional compilation of CoreMIDI and MidiShare drivers)
98 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
99     './configure --disable-asm' (definitely not recommended)
100 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
101     - require automake (>= 1.5) for 'make -f Makefile.cvs'
102     (due to 'dist-bzip2' automake option)
103 schoenebeck 649
104     * Gigasampler format engine:
105     - support for the gig parameters for "release velocity response" curves
106     - fine tuning of the EGADSR envelope
107     - volume of release triggered samples now depends on note-on velocity,
108     note length and gig parameter "release trigger decay" instead of
109     note-off velocity.
110 schoenebeck 663 - revised voice stealing
111     (fixes crash and endless loop caused by voice stealing)
112 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
113 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
114     instead of when the respective voice is actually launched
115     (fixes undefined behavior if stolen voices belonged to a key group -
116     this case was followed by a "killed voice survived" error message)
117 schoenebeck 669 - fixed minor issue with null/silence samples
118     (those stole voices even though they don't need a voice at all which
119     resulted in "voice stealing didn't work out" messages)
120 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
121     instrument or audio output device change
122 schoenebeck 654
123 schoenebeck 620 * LSCP server:
124 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
125 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
126 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
127 schoenebeck 609
128 schoenebeck 668 * linuxsampler application:
129     - added command line parameters --lscp-addr and --lscp-port to override
130     default IP address and port of LSCP server
131    
132 schoenebeck 579 Version 0.3.1 (24 May 2005)
133    
134     * initial release
