* added compile time options to allow disabling the various audio and MIDI
  drivers (./configure --disable-foo-driver)

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 852 - added compile time options to allow disabling the various audio and
18     MIDI drivers
19 schoenebeck 697
20 persson 696 * Gigasampler format engine:
21 schoenebeck 738 - extensive synthesis optimization
22     (reimplementation of EGs and LFO(s), removed synthesis parameter
23     prerendering and the synthesis parameter matrix in general, splitting
24     each audio fragment into subfragments now where each subfragment uses
25 persson 830 constant pitch and filter coefficients. The volume coefficient is
26     linearly interpolated inside a subfragment, unless
27     --disable-interpolate-volume is set.)
28 persson 696 - fine tuning of the EG modulation parameters
29 persson 729 - improved filter cutoff calculation by adding support for the
30     following gig parameters: Cutoff freq (used when no cutoff
31     controller is defined), Control invert, Minimum cutoff, Velocity
32 persson 791 curve and Velocity range. The keyboard tracking now scales
33     cutoff frequency instead of resonance.
34     - filter fine tuning: calculation of cutoff frequency and
35     bandwidth improved. Removed use of "BasicBPFilter". Changed
36     bandpass filter from constant peak to constant skirt. Added
37     support for gig parameter Resonance.
38 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
39 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
40     which can be overridden with --enable-global-attenuation
41 persson 783 - EG fixes: made the length of "attack hold" stage more
42     accurate. Release stage can now start before attack stage
43 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
44     time now has a minimal value to prevent clicks.
45 persson 799 - fixed pitch changes larger than one octave
46 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
47     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
48     all modes can be altered via standard GM messages, that is CC5 for
49     altering portamento time, CC65 for enabling / disabling portamento
50     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
51 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
52     parameter) and crossfade
53 persson 831 - added support for the "attenuation controller threshold" gig
54     parameter
55 persson 832 - added smoothing of volume changes caused by control change
56     messages
57 persson 696
58 schoenebeck 711 * LSCP server:
59     - fixed application exit on broken pipe error (fixes bug #20)
60 iliev 793 - fixed the notification messages delay due to lack of
61     network activity (fixes bug #26)
62 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
63     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
64 schoenebeck 711
65 schoenebeck 838 * audio driver:
66     - added aRts audio output driver (by no means RT safe)
67    
68 schoenebeck 775 * MIDI driver:
69     - fixed legacy sysex code which caused dispatching of MIDI SysEx
70     messages several times instead of once
71    
72 schoenebeck 705 * general changes:
73     - support for muting sampler channels and solo mode of the same, two new
74     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
75     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
76     introduced for this, the behavior is the same like on a mixer console
77 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
78     --enable-process-muted-channels which can be used to enable the
79     processing of muted channels.
80 iliev 777 - support for sostenuto pedal
81 iliev 779 - support for monitoring the total number of active voices
82 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
83     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
84 persson 835 - fixed some memory management errors
85 persson 841 - fixed some concurrency problems that could lead to crashes when
86     LSCP commands were executed
87 schoenebeck 705
88 schoenebeck 692 Version 0.3.3 (15 July 2005)
89 schoenebeck 686
90     * packaging changes:
91     - fixed compilation with gcc 4.0
92    
93 schoenebeck 687 * Gigasampler format engine:
94     - LFO preprocessing was performed even though the respective LFO was
95     disabled by the instrument patch (minor efficiency fix)
96 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
97     for volume ramp downs in the same fragment (needed for current voice
98     stealing implementation) then simply inform the user with a warning
99     about possible click sounds and reduce the volume ramp down
100     appropriately instead of cancelling the audio device connection
101 schoenebeck 687
102 schoenebeck 677 Version 0.3.2 (24 June 2005)
103 schoenebeck 609
104     * packaging changes:
105     - updated autotools build files to compile on OS X
106     (conditional compilation of CoreMIDI and MidiShare drivers)
107 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
108     './configure --disable-asm' (definitely not recommended)
109 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
110     - require automake (>= 1.5) for 'make -f Makefile.cvs'
111     (due to 'dist-bzip2' automake option)
112 schoenebeck 649
113     * Gigasampler format engine:
114     - support for the gig parameters for "release velocity response" curves
115     - fine tuning of the EGADSR envelope
116     - volume of release triggered samples now depends on note-on velocity,
117     note length and gig parameter "release trigger decay" instead of
118     note-off velocity.
119 schoenebeck 663 - revised voice stealing
120     (fixes crash and endless loop caused by voice stealing)
121 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
122 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
123     instead of when the respective voice is actually launched
124     (fixes undefined behavior if stolen voices belonged to a key group -
125     this case was followed by a "killed voice survived" error message)
126 schoenebeck 669 - fixed minor issue with null/silence samples
127     (those stole voices even though they don't need a voice at all which
128     resulted in "voice stealing didn't work out" messages)
129 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
130     instrument or audio output device change
131 schoenebeck 654
132 schoenebeck 620 * LSCP server:
133 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
134 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
135 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
136 schoenebeck 609
137 schoenebeck 668 * linuxsampler application:
138     - added command line parameters --lscp-addr and --lscp-port to override
139     default IP address and port of LSCP server
140    
141 schoenebeck 579 Version 0.3.1 (24 May 2005)
142    
143     * initial release
