* fixed crash occurring on certain LSCP scripts (Bug 39)

1 schoenebeck 947 Version CVS HEAD (?)
2    
3     * general changes:
4     - replaced the old, confusing MIDI program change mechanism by a
5     flexible MIDI instrument mapper which allows to map arbitrary
6     (MIDI bank MSB, MIDI bank LSB, MIDI program) triplets with arbitrary
7     (engine type, instrument file, file index) triplets which will be
8     loaded on the respective channel when such MIDI program change
9     messages arrive, beside that, each entry allows to define a life-time
10     strategy for the instrument, so the user can define whether the
11     instrument should i.e. be permanently loaded (to be able to switch
12     quickly among sounds) or i.e. loaded just on demand when the
13     respective program change arrives (to safe RAM space), as well as a
14     global volume factor for each entry, so the user can adjust the volume
15     dynamic of his mapped instrument collection without having to modify
16     the instrument files
17    
18     * MIDI driver:
19     - dispatch bank select (MSB and LSB) messages
20    
21 persson 951 * Gigasampler format engine:
22     - if a filter is used and EG2 finishes before EG1, let the voice
23     die when EG2 has finished (this fixes a problem with clicks and
24     voice starvation for some gigs)
25    
26 iliev 959 * Bug fixes:
27     - fixed crash occurring on certain LSCP scripts (Bug 39)
28    
29 schoenebeck 937 Version 0.4.0 (24 November 2006)
30 persson 696
31 schoenebeck 697 * packaging changes:
32 capela 868 - changed deprecated copyright attribute to license; added ldconfig
33     to post-(un)install steps; added devel package for liblinuxsampler;
34     to linuxsampler.spec (RPM)
35 schoenebeck 697 - install necessary development header files for allowing 3rd party
36     applications to link against liblinuxsampler
37     - liblinuxsampler's API documentation can be generated with 'make docs'
38     (Doxygen required)
39 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
40     implementation (currently either an integer math solution or a
41     di-harmonic approximation), automatic detection can be overriden
42     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
43     configure script argument though (mandatory for cross-compilation)
44 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
45     provided some on his own (as CXXFLAGS)
46 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
47     messages
48 schoenebeck 852 - added compile time options to allow disabling the various audio and
49     MIDI drivers
50 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
51     (patch by Ebrahim Mayat)
52 schoenebeck 697
53 persson 696 * Gigasampler format engine:
54 schoenebeck 738 - extensive synthesis optimization
55     (reimplementation of EGs and LFO(s), removed synthesis parameter
56     prerendering and the synthesis parameter matrix in general, splitting
57     each audio fragment into subfragments now where each subfragment uses
58 persson 830 constant pitch and filter coefficients. The volume coefficient is
59     linearly interpolated inside a subfragment, unless
60     --disable-interpolate-volume is set.)
61 persson 696 - fine tuning of the EG modulation parameters
62 persson 729 - improved filter cutoff calculation by adding support for the
63     following gig parameters: Cutoff freq (used when no cutoff
64     controller is defined), Control invert, Minimum cutoff, Velocity
65 persson 791 curve and Velocity range. The keyboard tracking now scales
66     cutoff frequency instead of resonance.
67 persson 877 - added support for gig parameter Resonance.
68 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
69 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
70     which can be overridden with --enable-global-attenuation
71 persson 783 - EG fixes: made the length of "attack hold" stage more
72     accurate. Release stage can now start before attack stage
73 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
74     time now has a minimal value to prevent clicks.
75 persson 799 - fixed pitch changes larger than one octave
76 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
77     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
78     all modes can be altered via standard GM messages, that is CC5 for
79     altering portamento time, CC65 for enabling / disabling portamento
80     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
81 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
82     parameter) and crossfade
83 persson 831 - added support for the "attenuation controller threshold" gig
84     parameter
85 persson 832 - added smoothing of volume changes caused by control change
86     messages
87 persson 865 - sample loop parameters are now taken from the DimensionRegion
88     instead of the wave chunk
89     - fixed keyswitching for v3 gigs with a number of keyswitch splits
90     not equal to a power of two
91 persson 877 - reimplementation of the filter algorithm. The new filter is more
92     accurate and supports all gig filter types, including bandreject
93     and lowpass turbo.
94 persson 903 - real support for 24 bit samples - samples are not truncated to
95     16 bits anymore
96     - support for aftertouch (channel pressure, not polyphonic
97     aftertouch)
98 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
99     amplifying from 0)
100 persson 696
101 schoenebeck 711 * LSCP server:
102     - fixed application exit on broken pipe error (fixes bug #20)
103 iliev 793 - fixed the notification messages delay due to lack of
104     network activity (fixes bug #26)
105 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
106     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
107 schoenebeck 711
108 schoenebeck 838 * audio driver:
109     - added aRts audio output driver (by no means RT safe)
110    
111 schoenebeck 775 * MIDI driver:
112     - fixed legacy sysex code which caused dispatching of MIDI SysEx
113     messages several times instead of once
114 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
115     for events (i.e. for offline rendering based MIDI drivers)
116 persson 922 - added checks for bad MIDI data
117 schoenebeck 775
118 schoenebeck 900 * linuxsampler application:
119     - show available sampler engine types on startup
120    
121 schoenebeck 705 * general changes:
122     - support for muting sampler channels and solo mode of the same, two new
123     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
124     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
125     introduced for this, the behavior is the same like on a mixer console
126 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
127     --enable-process-muted-channels which can be used to enable the
128     processing of muted channels.
129 iliev 777 - support for sostenuto pedal
130 iliev 779 - support for monitoring the total number of active voices
131 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
132     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
133 persson 835 - fixed some memory management errors
134 persson 841 - fixed some concurrency problems that could lead to crashes when
135     LSCP commands were executed
136 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
137     sampler channel (fixes bug #36)
138 schoenebeck 705
139 schoenebeck 692 Version 0.3.3 (15 July 2005)
140 schoenebeck 686
141     * packaging changes:
142     - fixed compilation with gcc 4.0
143    
144 schoenebeck 687 * Gigasampler format engine:
145     - LFO preprocessing was performed even though the respective LFO was
146     disabled by the instrument patch (minor efficiency fix)
147 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
148     for volume ramp downs in the same fragment (needed for current voice
149     stealing implementation) then simply inform the user with a warning
150     about possible click sounds and reduce the volume ramp down
151     appropriately instead of cancelling the audio device connection
152 schoenebeck 687
153 schoenebeck 677 Version 0.3.2 (24 June 2005)
154 schoenebeck 609
155     * packaging changes:
156     - updated autotools build files to compile on OS X
157     (conditional compilation of CoreMIDI and MidiShare drivers)
158 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
159     './configure --disable-asm' (definitely not recommended)
160 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
161     - require automake (>= 1.5) for 'make -f Makefile.cvs'
162     (due to 'dist-bzip2' automake option)
163 schoenebeck 649
164     * Gigasampler format engine:
165     - support for the gig parameters for "release velocity response" curves
166     - fine tuning of the EGADSR envelope
167     - volume of release triggered samples now depends on note-on velocity,
168     note length and gig parameter "release trigger decay" instead of
169     note-off velocity.
170 schoenebeck 663 - revised voice stealing
171     (fixes crash and endless loop caused by voice stealing)
172 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
173 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
174     instead of when the respective voice is actually launched
175     (fixes undefined behavior if stolen voices belonged to a key group -
176     this case was followed by a "killed voice survived" error message)
177 schoenebeck 669 - fixed minor issue with null/silence samples
178     (those stole voices even though they don't need a voice at all which
179     resulted in "voice stealing didn't work out" messages)
180 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
181     instrument or audio output device change
182 schoenebeck 654
183 schoenebeck 620 * LSCP server:
184 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
185 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
186 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
187 schoenebeck 609
188 schoenebeck 668 * linuxsampler application:
189     - added command line parameters --lscp-addr and --lscp-port to override
190     default IP address and port of LSCP server
191    
192 schoenebeck 579 Version 0.3.1 (24 May 2005)
193    
194     * initial release
