* added compile time option to disable processing of All-Notes-Off
  MIDI messages

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 849 - added compile time option to disable processing of All-Notes-Off MIDI
16     messages
17 schoenebeck 697
18 persson 696 * Gigasampler format engine:
19 schoenebeck 738 - extensive synthesis optimization
20     (reimplementation of EGs and LFO(s), removed synthesis parameter
21     prerendering and the synthesis parameter matrix in general, splitting
22     each audio fragment into subfragments now where each subfragment uses
23 persson 830 constant pitch and filter coefficients. The volume coefficient is
24     linearly interpolated inside a subfragment, unless
25     --disable-interpolate-volume is set.)
26 persson 696 - fine tuning of the EG modulation parameters
27 persson 729 - improved filter cutoff calculation by adding support for the
28     following gig parameters: Cutoff freq (used when no cutoff
29     controller is defined), Control invert, Minimum cutoff, Velocity
30 persson 791 curve and Velocity range. The keyboard tracking now scales
31     cutoff frequency instead of resonance.
32     - filter fine tuning: calculation of cutoff frequency and
33     bandwidth improved. Removed use of "BasicBPFilter". Changed
34     bandpass filter from constant peak to constant skirt. Added
35     support for gig parameter Resonance.
36 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
37 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
38     which can be overridden with --enable-global-attenuation
39 persson 783 - EG fixes: made the length of "attack hold" stage more
40     accurate. Release stage can now start before attack stage
41 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
42     time now has a minimal value to prevent clicks.
43 persson 799 - fixed pitch changes larger than one octave
44 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
45     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
46     all modes can be altered via standard GM messages, that is CC5 for
47     altering portamento time, CC65 for enabling / disabling portamento
48     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
49 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
50     parameter) and crossfade
51 persson 831 - added support for the "attenuation controller threshold" gig
52     parameter
53 persson 832 - added smoothing of volume changes caused by control change
54     messages
55 persson 696
56 schoenebeck 711 * LSCP server:
57     - fixed application exit on broken pipe error (fixes bug #20)
58 iliev 793 - fixed the notification messages delay due to lack of
59     network activity (fixes bug #26)
60 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
61     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
62 schoenebeck 711
63 schoenebeck 838 * audio driver:
64     - added aRts audio output driver (by no means RT safe)
65    
66 schoenebeck 775 * MIDI driver:
67     - fixed legacy sysex code which caused dispatching of MIDI SysEx
68     messages several times instead of once
69    
70 schoenebeck 705 * general changes:
71     - support for muting sampler channels and solo mode of the same, two new
72     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
73     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
74     introduced for this, the behavior is the same like on a mixer console
75 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
76     --enable-process-muted-channels which can be used to enable the
77     processing of muted channels.
78 iliev 777 - support for sostenuto pedal
79 iliev 779 - support for monitoring the total number of active voices
80 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
81     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
82 persson 835 - fixed some memory management errors
83 persson 841 - fixed some concurrency problems that could lead to crashes when
84     LSCP commands were executed
85 schoenebeck 705
86 schoenebeck 692 Version 0.3.3 (15 July 2005)
87 schoenebeck 686
88     * packaging changes:
89     - fixed compilation with gcc 4.0
90    
91 schoenebeck 687 * Gigasampler format engine:
92     - LFO preprocessing was performed even though the respective LFO was
93     disabled by the instrument patch (minor efficiency fix)
94 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
95     for volume ramp downs in the same fragment (needed for current voice
96     stealing implementation) then simply inform the user with a warning
97     about possible click sounds and reduce the volume ramp down
98     appropriately instead of cancelling the audio device connection
99 schoenebeck 687
100 schoenebeck 677 Version 0.3.2 (24 June 2005)
101 schoenebeck 609
102     * packaging changes:
103     - updated autotools build files to compile on OS X
104     (conditional compilation of CoreMIDI and MidiShare drivers)
105 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
106     './configure --disable-asm' (definitely not recommended)
107 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
108     - require automake (>= 1.5) for 'make -f Makefile.cvs'
109     (due to 'dist-bzip2' automake option)
110 schoenebeck 649
111     * Gigasampler format engine:
112     - support for the gig parameters for "release velocity response" curves
113     - fine tuning of the EGADSR envelope
114     - volume of release triggered samples now depends on note-on velocity,
115     note length and gig parameter "release trigger decay" instead of
116     note-off velocity.
117 schoenebeck 663 - revised voice stealing
118     (fixes crash and endless loop caused by voice stealing)
119 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
120 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
121     instead of when the respective voice is actually launched
122     (fixes undefined behavior if stolen voices belonged to a key group -
123     this case was followed by a "killed voice survived" error message)
124 schoenebeck 669 - fixed minor issue with null/silence samples
125     (those stole voices even though they don't need a voice at all which
126     resulted in "voice stealing didn't work out" messages)
127 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
128     instrument or audio output device change
129 schoenebeck 654
130 schoenebeck 620 * LSCP server:
131 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
132 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
133 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
134 schoenebeck 609
135 schoenebeck 668 * linuxsampler application:
136     - added command line parameters --lscp-addr and --lscp-port to override
137     default IP address and port of LSCP server
138    
139 schoenebeck 579 Version 0.3.1 (24 May 2005)
140    
141     * initial release
