* fixed global pan (CC10) which hasn't been working for a while
* fine tuning of the curves for volume (CC7) and pan (CC10 and gig
  parameter)
* added support for the "attenuation controller threshold" gig
  parameter

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 831 - fine tuning of the curves for volume (CC7) and pan (CC10 and gig
48     parameter)
49     - added support for the "attenuation controller threshold" gig
50     parameter
51 persson 696
52 schoenebeck 711 * LSCP server:
53     - fixed application exit on broken pipe error (fixes bug #20)
54 iliev 793 - fixed the notification messages delay due to lack of
55     network activity (fixes bug #26)
56 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
57     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
58 schoenebeck 711
59 schoenebeck 775 * MIDI driver:
60     - fixed legacy sysex code which caused dispatching of MIDI SysEx
61     messages several times instead of once
62    
63 schoenebeck 705 * general changes:
64     - support for muting sampler channels and solo mode of the same, two new
65     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
66     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
67     introduced for this, the behavior is the same like on a mixer console
68 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
69     --enable-process-muted-channels which can be used to enable the
70     processing of muted channels.
71 iliev 777 - support for sostenuto pedal
72 iliev 779 - support for monitoring the total number of active voices
73 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
74     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
75 schoenebeck 705
76 schoenebeck 692 Version 0.3.3 (15 July 2005)
77 schoenebeck 686
78     * packaging changes:
79     - fixed compilation with gcc 4.0
80    
81 schoenebeck 687 * Gigasampler format engine:
82     - LFO preprocessing was performed even though the respective LFO was
83     disabled by the instrument patch (minor efficiency fix)
84 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
85     for volume ramp downs in the same fragment (needed for current voice
86     stealing implementation) then simply inform the user with a warning
87     about possible click sounds and reduce the volume ramp down
88     appropriately instead of cancelling the audio device connection
89 schoenebeck 687
90 schoenebeck 677 Version 0.3.2 (24 June 2005)
91 schoenebeck 609
92     * packaging changes:
93     - updated autotools build files to compile on OS X
94     (conditional compilation of CoreMIDI and MidiShare drivers)
95 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
96     './configure --disable-asm' (definitely not recommended)
97 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
98     - require automake (>= 1.5) for 'make -f Makefile.cvs'
99     (due to 'dist-bzip2' automake option)
100 schoenebeck 649
101     * Gigasampler format engine:
102     - support for the gig parameters for "release velocity response" curves
103     - fine tuning of the EGADSR envelope
104     - volume of release triggered samples now depends on note-on velocity,
105     note length and gig parameter "release trigger decay" instead of
106     note-off velocity.
107 schoenebeck 663 - revised voice stealing
108     (fixes crash and endless loop caused by voice stealing)
109 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
110 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
111     instead of when the respective voice is actually launched
112     (fixes undefined behavior if stolen voices belonged to a key group -
113     this case was followed by a "killed voice survived" error message)
114 schoenebeck 669 - fixed minor issue with null/silence samples
115     (those stole voices even though they don't need a voice at all which
116     resulted in "voice stealing didn't work out" messages)
117 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
118     instrument or audio output device change
119 schoenebeck 654
120 schoenebeck 620 * LSCP server:
121 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
122 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
123 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
124 schoenebeck 609
125 schoenebeck 668 * linuxsampler application:
126     - added command line parameters --lscp-addr and --lscp-port to override
127     default IP address and port of LSCP server
128    
129 schoenebeck 579 Version 0.3.1 (24 May 2005)
130    
131     * initial release
