- added forgotten notice in ChangeLog
- fixed LIST MIDI_INSTRUMENTS

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 schoenebeck 937 Version 0.4.0 (24 November 2006)
27 persson 696
28 schoenebeck 697 * packaging changes:
29 capela 868 - changed deprecated copyright attribute to license; added ldconfig
30     to post-(un)install steps; added devel package for liblinuxsampler;
31     to linuxsampler.spec (RPM)
32 schoenebeck 697 - install necessary development header files for allowing 3rd party
33     applications to link against liblinuxsampler
34     - liblinuxsampler's API documentation can be generated with 'make docs'
35     (Doxygen required)
36 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
37     implementation (currently either an integer math solution or a
38     di-harmonic approximation), automatic detection can be overriden
39     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
40     configure script argument though (mandatory for cross-compilation)
41 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
42     provided some on his own (as CXXFLAGS)
43 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
44     messages
45 schoenebeck 852 - added compile time options to allow disabling the various audio and
46     MIDI drivers
47 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
48     (patch by Ebrahim Mayat)
49 schoenebeck 697
50 persson 696 * Gigasampler format engine:
51 schoenebeck 738 - extensive synthesis optimization
52     (reimplementation of EGs and LFO(s), removed synthesis parameter
53     prerendering and the synthesis parameter matrix in general, splitting
54     each audio fragment into subfragments now where each subfragment uses
55 persson 830 constant pitch and filter coefficients. The volume coefficient is
56     linearly interpolated inside a subfragment, unless
57     --disable-interpolate-volume is set.)
58 persson 696 - fine tuning of the EG modulation parameters
59 persson 729 - improved filter cutoff calculation by adding support for the
60     following gig parameters: Cutoff freq (used when no cutoff
61     controller is defined), Control invert, Minimum cutoff, Velocity
62 persson 791 curve and Velocity range. The keyboard tracking now scales
63     cutoff frequency instead of resonance.
64 persson 877 - added support for gig parameter Resonance.
65 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
66 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
67     which can be overridden with --enable-global-attenuation
68 persson 783 - EG fixes: made the length of "attack hold" stage more
69     accurate. Release stage can now start before attack stage
70 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
71     time now has a minimal value to prevent clicks.
72 persson 799 - fixed pitch changes larger than one octave
73 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
74     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
75     all modes can be altered via standard GM messages, that is CC5 for
76     altering portamento time, CC65 for enabling / disabling portamento
77     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
78 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
79     parameter) and crossfade
80 persson 831 - added support for the "attenuation controller threshold" gig
81     parameter
82 persson 832 - added smoothing of volume changes caused by control change
83     messages
84 persson 865 - sample loop parameters are now taken from the DimensionRegion
85     instead of the wave chunk
86     - fixed keyswitching for v3 gigs with a number of keyswitch splits
87     not equal to a power of two
88 persson 877 - reimplementation of the filter algorithm. The new filter is more
89     accurate and supports all gig filter types, including bandreject
90     and lowpass turbo.
91 persson 903 - real support for 24 bit samples - samples are not truncated to
92     16 bits anymore
93     - support for aftertouch (channel pressure, not polyphonic
94     aftertouch)
95 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
96     amplifying from 0)
97 persson 696
98 schoenebeck 711 * LSCP server:
99     - fixed application exit on broken pipe error (fixes bug #20)
100 iliev 793 - fixed the notification messages delay due to lack of
101     network activity (fixes bug #26)
102 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
103     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
104 schoenebeck 711
105 schoenebeck 838 * audio driver:
106     - added aRts audio output driver (by no means RT safe)
107    
108 schoenebeck 775 * MIDI driver:
109     - fixed legacy sysex code which caused dispatching of MIDI SysEx
110     messages several times instead of once
111 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
112     for events (i.e. for offline rendering based MIDI drivers)
113 persson 922 - added checks for bad MIDI data
114 schoenebeck 775
115 schoenebeck 900 * linuxsampler application:
116     - show available sampler engine types on startup
117    
118 schoenebeck 705 * general changes:
119     - support for muting sampler channels and solo mode of the same, two new
120     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
121     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
122     introduced for this, the behavior is the same like on a mixer console
123 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
124     --enable-process-muted-channels which can be used to enable the
125     processing of muted channels.
126 iliev 777 - support for sostenuto pedal
127 iliev 779 - support for monitoring the total number of active voices
128 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
129     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
130 persson 835 - fixed some memory management errors
131 persson 841 - fixed some concurrency problems that could lead to crashes when
132     LSCP commands were executed
133 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
134     sampler channel (fixes bug #36)
135 schoenebeck 705
136 schoenebeck 692 Version 0.3.3 (15 July 2005)
137 schoenebeck 686
138     * packaging changes:
139     - fixed compilation with gcc 4.0
140    
141 schoenebeck 687 * Gigasampler format engine:
142     - LFO preprocessing was performed even though the respective LFO was
143     disabled by the instrument patch (minor efficiency fix)
144 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
145     for volume ramp downs in the same fragment (needed for current voice
146     stealing implementation) then simply inform the user with a warning
147     about possible click sounds and reduce the volume ramp down
148     appropriately instead of cancelling the audio device connection
149 schoenebeck 687
150 schoenebeck 677 Version 0.3.2 (24 June 2005)
151 schoenebeck 609
152     * packaging changes:
153     - updated autotools build files to compile on OS X
154     (conditional compilation of CoreMIDI and MidiShare drivers)
155 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
156     './configure --disable-asm' (definitely not recommended)
157 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
158     - require automake (>= 1.5) for 'make -f Makefile.cvs'
159     (due to 'dist-bzip2' automake option)
160 schoenebeck 649
161     * Gigasampler format engine:
162     - support for the gig parameters for "release velocity response" curves
163     - fine tuning of the EGADSR envelope
164     - volume of release triggered samples now depends on note-on velocity,
165     note length and gig parameter "release trigger decay" instead of
166     note-off velocity.
167 schoenebeck 663 - revised voice stealing
168     (fixes crash and endless loop caused by voice stealing)
169 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
170 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
171     instead of when the respective voice is actually launched
172     (fixes undefined behavior if stolen voices belonged to a key group -
173     this case was followed by a "killed voice survived" error message)
174 schoenebeck 669 - fixed minor issue with null/silence samples
175     (those stole voices even though they don't need a voice at all which
176     resulted in "voice stealing didn't work out" messages)
177 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
178     instrument or audio output device change
179 schoenebeck 654
180 schoenebeck 620 * LSCP server:
181 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
182 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
183 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
184 schoenebeck 609
185 schoenebeck 668 * linuxsampler application:
186     - added command line parameters --lscp-addr and --lscp-port to override
187     default IP address and port of LSCP server
188    
189 schoenebeck 579 Version 0.3.1 (24 May 2005)
190    
191     * initial release
