* implemented MIDI instrument mapping according to latest LSCP draft

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