* preparations for release 0.4.0

1 schoenebeck 937 Version 0.4.0 (24 November 2006)
2 persson 696
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 909 - fixed automatic GCC CPU switch detection on PPC
23     (patch by Ebrahim Mayat)
24 schoenebeck 697
25 persson 696 * Gigasampler format engine:
26 schoenebeck 738 - extensive synthesis optimization
27     (reimplementation of EGs and LFO(s), removed synthesis parameter
28     prerendering and the synthesis parameter matrix in general, splitting
29     each audio fragment into subfragments now where each subfragment uses
30 persson 830 constant pitch and filter coefficients. The volume coefficient is
31     linearly interpolated inside a subfragment, unless
32     --disable-interpolate-volume is set.)
33 persson 696 - fine tuning of the EG modulation parameters
34 persson 729 - improved filter cutoff calculation by adding support for the
35     following gig parameters: Cutoff freq (used when no cutoff
36     controller is defined), Control invert, Minimum cutoff, Velocity
37 persson 791 curve and Velocity range. The keyboard tracking now scales
38     cutoff frequency instead of resonance.
39 persson 877 - added support for gig parameter Resonance.
40 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
41 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
42     which can be overridden with --enable-global-attenuation
43 persson 783 - EG fixes: made the length of "attack hold" stage more
44     accurate. Release stage can now start before attack stage
45 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
46     time now has a minimal value to prevent clicks.
47 persson 799 - fixed pitch changes larger than one octave
48 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
49     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
50     all modes can be altered via standard GM messages, that is CC5 for
51     altering portamento time, CC65 for enabling / disabling portamento
52     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
53 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
54     parameter) and crossfade
55 persson 831 - added support for the "attenuation controller threshold" gig
56     parameter
57 persson 832 - added smoothing of volume changes caused by control change
58     messages
59 persson 865 - sample loop parameters are now taken from the DimensionRegion
60     instead of the wave chunk
61     - fixed keyswitching for v3 gigs with a number of keyswitch splits
62     not equal to a power of two
63 persson 877 - reimplementation of the filter algorithm. The new filter is more
64     accurate and supports all gig filter types, including bandreject
65     and lowpass turbo.
66 persson 903 - real support for 24 bit samples - samples are not truncated to
67     16 bits anymore
68     - support for aftertouch (channel pressure, not polyphonic
69     aftertouch)
70 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
71     amplifying from 0)
72 persson 696
73 schoenebeck 711 * LSCP server:
74     - fixed application exit on broken pipe error (fixes bug #20)
75 iliev 793 - fixed the notification messages delay due to lack of
76     network activity (fixes bug #26)
77 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
78     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
79 schoenebeck 711
80 schoenebeck 838 * audio driver:
81     - added aRts audio output driver (by no means RT safe)
82    
83 schoenebeck 775 * MIDI driver:
84     - fixed legacy sysex code which caused dispatching of MIDI SysEx
85     messages several times instead of once
86 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
87     for events (i.e. for offline rendering based MIDI drivers)
88 persson 922 - added checks for bad MIDI data
89 schoenebeck 775
90 schoenebeck 900 * linuxsampler application:
91     - show available sampler engine types on startup
92    
93 schoenebeck 705 * general changes:
94     - support for muting sampler channels and solo mode of the same, two new
95     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
96     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
97     introduced for this, the behavior is the same like on a mixer console
98 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
99     --enable-process-muted-channels which can be used to enable the
100     processing of muted channels.
101 iliev 777 - support for sostenuto pedal
102 iliev 779 - support for monitoring the total number of active voices
103 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
104     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
105 persson 835 - fixed some memory management errors
106 persson 841 - fixed some concurrency problems that could lead to crashes when
107     LSCP commands were executed
108 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
109     sampler channel (fixes bug #36)
110 schoenebeck 705
111 schoenebeck 692 Version 0.3.3 (15 July 2005)
112 schoenebeck 686
113     * packaging changes:
114     - fixed compilation with gcc 4.0
115    
116 schoenebeck 687 * Gigasampler format engine:
117     - LFO preprocessing was performed even though the respective LFO was
118     disabled by the instrument patch (minor efficiency fix)
119 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
120     for volume ramp downs in the same fragment (needed for current voice
121     stealing implementation) then simply inform the user with a warning
122     about possible click sounds and reduce the volume ramp down
123     appropriately instead of cancelling the audio device connection
124 schoenebeck 687
125 schoenebeck 677 Version 0.3.2 (24 June 2005)
126 schoenebeck 609
127     * packaging changes:
128     - updated autotools build files to compile on OS X
129     (conditional compilation of CoreMIDI and MidiShare drivers)
130 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
131     './configure --disable-asm' (definitely not recommended)
132 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
133     - require automake (>= 1.5) for 'make -f Makefile.cvs'
134     (due to 'dist-bzip2' automake option)
135 schoenebeck 649
136     * Gigasampler format engine:
137     - support for the gig parameters for "release velocity response" curves
138     - fine tuning of the EGADSR envelope
139     - volume of release triggered samples now depends on note-on velocity,
140     note length and gig parameter "release trigger decay" instead of
141     note-off velocity.
142 schoenebeck 663 - revised voice stealing
143     (fixes crash and endless loop caused by voice stealing)
144 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
145 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
146     instead of when the respective voice is actually launched
147     (fixes undefined behavior if stolen voices belonged to a key group -
148     this case was followed by a "killed voice survived" error message)
149 schoenebeck 669 - fixed minor issue with null/silence samples
150     (those stole voices even though they don't need a voice at all which
151     resulted in "voice stealing didn't work out" messages)
152 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
153     instrument or audio output device change
154 schoenebeck 654
155 schoenebeck 620 * LSCP server:
156 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
157 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
158 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
159 schoenebeck 609
160 schoenebeck 668 * linuxsampler application:
161     - added command line parameters --lscp-addr and --lscp-port to override
162     default IP address and port of LSCP server
163    
164 schoenebeck 579 Version 0.3.1 (24 May 2005)
165    
166     * initial release
