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 schoenebeck 973 (MIDI bank, MIDI program) pairs with arbitrary
7 schoenebeck 947 (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 schoenebeck 973 the instrument files, also one can manage arbitrary amount of such
17     MIDI instrument maps and assign each sampler channel individually
18     a certain map, so that i.e. separation of normal instruments and
19     drumkits is possible
20 iliev 981 - new notification events for tracking audio/MIDI device changes,
21     MIDI instrument map changes and MIDI instrument changes
22 schoenebeck 990 - sampler was limited to load max. 200 instruments in the background
23     due to a constant size RingBuffer FIFO which is now replaced by a
24     dynamic (unlimited) size std::list FIFO
25 schoenebeck 947
26     * MIDI driver:
27     - dispatch bank select (MSB and LSB) messages
28    
29 persson 951 * Gigasampler format engine:
30     - if a filter is used and EG2 finishes before EG1, let the voice
31     die when EG2 has finished (this fixes a problem with clicks and
32     voice starvation for some gigs)
33    
34 iliev 959 * Bug fixes:
35     - fixed crash occurring on certain LSCP scripts (Bug 39)
36    
37 schoenebeck 937 Version 0.4.0 (24 November 2006)
38 persson 696
39 schoenebeck 697 * packaging changes:
40 capela 868 - changed deprecated copyright attribute to license; added ldconfig
41     to post-(un)install steps; added devel package for liblinuxsampler;
42     to linuxsampler.spec (RPM)
43 schoenebeck 697 - install necessary development header files for allowing 3rd party
44     applications to link against liblinuxsampler
45     - liblinuxsampler's API documentation can be generated with 'make docs'
46     (Doxygen required)
47 schoenebeck 715 - added benchmark to automatically detect the best triangle LFO
48     implementation (currently either an integer math solution or a
49     di-harmonic approximation), automatic detection can be overriden
50     with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
51     configure script argument though (mandatory for cross-compilation)
52 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
53     provided some on his own (as CXXFLAGS)
54 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
55     messages
56 schoenebeck 852 - added compile time options to allow disabling the various audio and
57     MIDI drivers
58 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
59     (patch by Ebrahim Mayat)
60 schoenebeck 697
61 persson 696 * Gigasampler format engine:
62 schoenebeck 738 - extensive synthesis optimization
63     (reimplementation of EGs and LFO(s), removed synthesis parameter
64     prerendering and the synthesis parameter matrix in general, splitting
65     each audio fragment into subfragments now where each subfragment uses
66 persson 830 constant pitch and filter coefficients. The volume coefficient is
67     linearly interpolated inside a subfragment, unless
68     --disable-interpolate-volume is set.)
69 persson 696 - fine tuning of the EG modulation parameters
70 persson 729 - improved filter cutoff calculation by adding support for the
71     following gig parameters: Cutoff freq (used when no cutoff
72     controller is defined), Control invert, Minimum cutoff, Velocity
73 persson 791 curve and Velocity range. The keyboard tracking now scales
74     cutoff frequency instead of resonance.
75 persson 877 - added support for gig parameter Resonance.
76 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
77 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
78     which can be overridden with --enable-global-attenuation
79 persson 783 - EG fixes: made the length of "attack hold" stage more
80     accurate. Release stage can now start before attack stage
81 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
82     time now has a minimal value to prevent clicks.
83 persson 799 - fixed pitch changes larger than one octave
84 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
85     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
86     all modes can be altered via standard GM messages, that is CC5 for
87     altering portamento time, CC65 for enabling / disabling portamento
88     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
89 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
90     parameter) and crossfade
91 persson 831 - added support for the "attenuation controller threshold" gig
92     parameter
93 persson 832 - added smoothing of volume changes caused by control change
94     messages
95 persson 865 - sample loop parameters are now taken from the DimensionRegion
96     instead of the wave chunk
97     - fixed keyswitching for v3 gigs with a number of keyswitch splits
98     not equal to a power of two
99 persson 877 - reimplementation of the filter algorithm. The new filter is more
100     accurate and supports all gig filter types, including bandreject
101     and lowpass turbo.
102 persson 903 - real support for 24 bit samples - samples are not truncated to
103     16 bits anymore
104     - support for aftertouch (channel pressure, not polyphonic
105     aftertouch)
106 persson 922 - LFO1 behaviour fixed (dampening from max volume instead of
107     amplifying from 0)
108 persson 696
109 schoenebeck 711 * LSCP server:
110     - fixed application exit on broken pipe error (fixes bug #20)
111 iliev 793 - fixed the notification messages delay due to lack of
112     network activity (fixes bug #26)
113 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
114     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
115 schoenebeck 711
116 schoenebeck 838 * audio driver:
117     - added aRts audio output driver (by no means RT safe)
118    
119 schoenebeck 775 * MIDI driver:
120     - fixed legacy sysex code which caused dispatching of MIDI SysEx
121     messages several times instead of once
122 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
123     for events (i.e. for offline rendering based MIDI drivers)
124 persson 922 - added checks for bad MIDI data
125 schoenebeck 775
126 schoenebeck 900 * linuxsampler application:
127     - show available sampler engine types on startup
128    
129 schoenebeck 705 * general changes:
130     - support for muting sampler channels and solo mode of the same, two new
131     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
132     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
133     introduced for this, the behavior is the same like on a mixer console
134 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
135     --enable-process-muted-channels which can be used to enable the
136     processing of muted channels.
137 iliev 777 - support for sostenuto pedal
138 iliev 779 - support for monitoring the total number of active voices
139 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
140     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
141 persson 835 - fixed some memory management errors
142 persson 841 - fixed some concurrency problems that could lead to crashes when
143     LSCP commands were executed
144 schoenebeck 925 - fixed crash when instrument loading failed previously on the same
145     sampler channel (fixes bug #36)
146 schoenebeck 705
147 schoenebeck 692 Version 0.3.3 (15 July 2005)
148 schoenebeck 686
149     * packaging changes:
150     - fixed compilation with gcc 4.0
151    
152 schoenebeck 687 * Gigasampler format engine:
153     - LFO preprocessing was performed even though the respective LFO was
154     disabled by the instrument patch (minor efficiency fix)
155 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
156     for volume ramp downs in the same fragment (needed for current voice
157     stealing implementation) then simply inform the user with a warning
158     about possible click sounds and reduce the volume ramp down
159     appropriately instead of cancelling the audio device connection
160 schoenebeck 687
161 schoenebeck 677 Version 0.3.2 (24 June 2005)
162 schoenebeck 609
163     * packaging changes:
164     - updated autotools build files to compile on OS X
165     (conditional compilation of CoreMIDI and MidiShare drivers)
166 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
167     './configure --disable-asm' (definitely not recommended)
168 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
169     - require automake (>= 1.5) for 'make -f Makefile.cvs'
170     (due to 'dist-bzip2' automake option)
171 schoenebeck 649
172     * Gigasampler format engine:
173     - support for the gig parameters for "release velocity response" curves
174     - fine tuning of the EGADSR envelope
175     - volume of release triggered samples now depends on note-on velocity,
176     note length and gig parameter "release trigger decay" instead of
177     note-off velocity.
178 schoenebeck 663 - revised voice stealing
179     (fixes crash and endless loop caused by voice stealing)
180 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
181 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
182     instead of when the respective voice is actually launched
183     (fixes undefined behavior if stolen voices belonged to a key group -
184     this case was followed by a "killed voice survived" error message)
185 schoenebeck 669 - fixed minor issue with null/silence samples
186     (those stole voices even though they don't need a voice at all which
187     resulted in "voice stealing didn't work out" messages)
188 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
189     instrument or audio output device change
190 schoenebeck 654
191 schoenebeck 620 * LSCP server:
192 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
193 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
194 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
195 schoenebeck 609
196 schoenebeck 668 * linuxsampler application:
197     - added command line parameters --lscp-addr and --lscp-port to override
198     default IP address and port of LSCP server
199    
200 schoenebeck 579 Version 0.3.1 (24 May 2005)
201    
202     * initial release
