* real support for 24 bit samples - samples are not truncated to 16
  bits anymore
* support for aftertouch (channel pressure, not polyphonic aftertouch)

1 persson 696 Version CVS HEAD (?)
2    
3 schoenebeck 697 * packaging changes:
4 capela 868 - changed deprecated copyright attribute to license; added ldconfig
5     to post-(un)install steps; added devel package for liblinuxsampler;
6     to linuxsampler.spec (RPM)
7 schoenebeck 697 - install necessary development header files for allowing 3rd party
8     applications to link against liblinuxsampler
9     - liblinuxsampler's API documentation can be generated with 'make docs'
10     (Doxygen required)
11 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
12     implementation (currently either an integer math solution or a
13     di-harmonic approximation), automatic detection can be overriden
14     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
15     configure script argument though (mandatory for cross-compilation)
16 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
17     provided some on his own (as CXXFLAGS)
18 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
19     messages
20 schoenebeck 852 - added compile time options to allow disabling the various audio and
21     MIDI drivers
22 schoenebeck 697
23 persson 696 * Gigasampler format engine:
24 schoenebeck 738 - extensive synthesis optimization
25     (reimplementation of EGs and LFO(s), removed synthesis parameter
26     prerendering and the synthesis parameter matrix in general, splitting
27     each audio fragment into subfragments now where each subfragment uses
28 persson 830 constant pitch and filter coefficients. The volume coefficient is
29     linearly interpolated inside a subfragment, unless
30     --disable-interpolate-volume is set.)
31 persson 696 - fine tuning of the EG modulation parameters
32 persson 729 - improved filter cutoff calculation by adding support for the
33     following gig parameters: Cutoff freq (used when no cutoff
34     controller is defined), Control invert, Minimum cutoff, Velocity
35 persson 791 curve and Velocity range. The keyboard tracking now scales
36     cutoff frequency instead of resonance.
37 persson 877 - added 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 865 - sample loop parameters are now taken from the DimensionRegion
58     instead of the wave chunk
59     - fixed keyswitching for v3 gigs with a number of keyswitch splits
60     not equal to a power of two
61 persson 877 - reimplementation of the filter algorithm. The new filter is more
62     accurate and supports all gig filter types, including bandreject
63     and lowpass turbo.
64 persson 903 - real support for 24 bit samples - samples are not truncated to
65     16 bits anymore
66     - support for aftertouch (channel pressure, not polyphonic
67     aftertouch)
68 persson 696
69 schoenebeck 711 * LSCP server:
70     - fixed application exit on broken pipe error (fixes bug #20)
71 iliev 793 - fixed the notification messages delay due to lack of
72     network activity (fixes bug #26)
73 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
74     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
75 schoenebeck 711
76 schoenebeck 838 * audio driver:
77     - added aRts audio output driver (by no means RT safe)
78    
79 schoenebeck 775 * MIDI driver:
80     - fixed legacy sysex code which caused dispatching of MIDI SysEx
81     messages several times instead of once
82    
83 schoenebeck 900 * linuxsampler application:
84     - show available sampler engine types on startup
85    
86 schoenebeck 705 * general changes:
87     - support for muting sampler channels and solo mode of the same, two new
88     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
89     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
90     introduced for this, the behavior is the same like on a mixer console
91 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
92     --enable-process-muted-channels which can be used to enable the
93     processing of muted channels.
94 iliev 777 - support for sostenuto pedal
95 iliev 779 - support for monitoring the total number of active voices
96 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
97     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
98 persson 835 - fixed some memory management errors
99 persson 841 - fixed some concurrency problems that could lead to crashes when
100     LSCP commands were executed
101 schoenebeck 705
102 schoenebeck 692 Version 0.3.3 (15 July 2005)
103 schoenebeck 686
104     * packaging changes:
105     - fixed compilation with gcc 4.0
106    
107 schoenebeck 687 * Gigasampler format engine:
108     - LFO preprocessing was performed even though the respective LFO was
109     disabled by the instrument patch (minor efficiency fix)
110 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
111     for volume ramp downs in the same fragment (needed for current voice
112     stealing implementation) then simply inform the user with a warning
113     about possible click sounds and reduce the volume ramp down
114     appropriately instead of cancelling the audio device connection
115 schoenebeck 687
116 schoenebeck 677 Version 0.3.2 (24 June 2005)
117 schoenebeck 609
118     * packaging changes:
119     - updated autotools build files to compile on OS X
120     (conditional compilation of CoreMIDI and MidiShare drivers)
121 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
122     './configure --disable-asm' (definitely not recommended)
123 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
124     - require automake (>= 1.5) for 'make -f Makefile.cvs'
125     (due to 'dist-bzip2' automake option)
126 schoenebeck 649
127     * Gigasampler format engine:
128     - support for the gig parameters for "release velocity response" curves
129     - fine tuning of the EGADSR envelope
130     - volume of release triggered samples now depends on note-on velocity,
131     note length and gig parameter "release trigger decay" instead of
132     note-off velocity.
133 schoenebeck 663 - revised voice stealing
134     (fixes crash and endless loop caused by voice stealing)
135 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
136 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
137     instead of when the respective voice is actually launched
138     (fixes undefined behavior if stolen voices belonged to a key group -
139     this case was followed by a "killed voice survived" error message)
140 schoenebeck 669 - fixed minor issue with null/silence samples
141     (those stole voices even though they don't need a voice at all which
142     resulted in "voice stealing didn't work out" messages)
143 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
144     instrument or audio output device change
145 schoenebeck 654
146 schoenebeck 620 * LSCP server:
147 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
148 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
149 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
150 schoenebeck 609
151 schoenebeck 668 * linuxsampler application:
152     - added command line parameters --lscp-addr and --lscp-port to override
153     default IP address and port of LSCP server
154    
155 schoenebeck 579 Version 0.3.1 (24 May 2005)
156    
157     * initial release
