* Added new notification events for tracking audio/MIDI device changes,
MIDI instrument map changes and MIDI instrument changes

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