3    * packaging changes:    * packaging changes:
4        - changed deprecated copyright attribute to license; added ldconfig
5          to post-(un)install steps; added devel package for liblinuxsampler;
6          to linuxsampler.spec (RPM)
7        - install necessary development header files for allowing 3rd party
8          applications to link against liblinuxsampler
9        - liblinuxsampler's API documentation can be generated with 'make docs'
10          (Doxygen required)
11        - added benchmark to automatically detect the best triangle LFO
12          implementation (currently either an integer math solution or a
13          di-harmonic approximation), automatic detection can be overriden
14          with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
15          configure script argument though (mandatory for cross-compilation)
16        - do not automatically pick optimized gcc flags if the user already
17          provided some on his own (as CXXFLAGS)
18        - added compile time option to disable processing of All-Notes-Off MIDI
19          messages
20        - added compile time options to allow disabling the various audio and
21          MIDI drivers
22    
23      * Gigasampler format engine:
24        - extensive synthesis optimization
25          (reimplementation of EGs and LFO(s), removed synthesis parameter
26          prerendering and the synthesis parameter matrix in general, splitting
27          each audio fragment into subfragments now where each subfragment uses
28          constant pitch and filter coefficients. The volume coefficient is
29          linearly interpolated inside a subfragment, unless
30          --disable-interpolate-volume is set.)
31        - fine tuning of the EG modulation parameters
32        - improved filter cutoff calculation by adding support for the
33          following gig parameters: Cutoff freq (used when no cutoff
34          controller is defined), Control invert, Minimum cutoff, Velocity
35          curve and Velocity range. The keyboard tracking now scales
36          cutoff frequency instead of resonance.
37        - added support for gig parameter Resonance.
38        - fixed bug in sysex handling (patch by Juan Linietsky)
39        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
40          which can be overridden with --enable-global-attenuation
41        - EG fixes: made the length of "attack hold" stage more
42          accurate. Release stage can now start before attack stage
43          ends. Cancel release didn't work when sustain was zero. Attack
44          time now has a minimal value to prevent clicks.
45        - fixed pitch changes larger than one octave
46        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
47        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
48          all modes can be altered via standard GM messages, that is CC5 for
49          altering portamento time, CC65 for enabling / disabling portamento
50          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
51        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
52          parameter) and crossfade
53        - added support for the "attenuation controller threshold" gig
54          parameter
55        - added smoothing of volume changes caused by control change
56          messages
57        - sample loop parameters are now taken from the DimensionRegion
58          instead of the wave chunk
59        - fixed keyswitching for v3 gigs with a number of keyswitch splits
60          not equal to a power of two
61        - reimplementation of the filter algorithm. The new filter is more
62          accurate and supports all gig filter types, including bandreject
63          and lowpass turbo.
64        - real support for 24 bit samples - samples are not truncated to
65          16 bits anymore
66        - support for aftertouch (channel pressure, not polyphonic
67          aftertouch)
68    
69      * LSCP server:
70        - fixed application exit on broken pipe error (fixes bug #20)
71        - fixed the notification messages delay due to lack of
72          network activity (fixes bug #26)
73        - fixed parser bug which occured on space(s) within device parameters
74          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
75    
76      * audio driver:
77        - added aRts audio output driver (by no means RT safe)
78    
79      * MIDI driver:
80        - fixed legacy sysex code which caused dispatching of MIDI SysEx
81          messages several times instead of once
82        - API extension for MIDI drivers which already supply exact time stamps
83          for events (i.e. for offline rendering based MIDI drivers)
84    
85      * linuxsampler application:
86        - show available sampler engine types on startup
87    
88      * general changes:
89        - support for muting sampler channels and solo mode of the same, two new
90          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
91          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
92          introduced for this, the behavior is the same like on a mixer console
93          (patch by Grigor Iliev, a bit adjusted). Also added configure option
94          --enable-process-muted-channels which can be used to enable the
95          processing of muted channels.
96        - support for sostenuto pedal
97        - support for monitoring the total number of active voices
98          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
99          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
100        - fixed some memory management errors
101        - fixed some concurrency problems that could lead to crashes when
102          LSCP commands were executed
103    
104    Version 0.3.3 (15 July 2005)
105    
106      * packaging changes:
107        - fixed compilation with gcc 4.0
108    
109      * Gigasampler format engine:
110        - LFO preprocessing was performed even though the respective LFO was
111          disabled by the instrument patch (minor efficiency fix)
112        - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
113          for volume ramp downs in the same fragment (needed for current voice
114          stealing implementation) then simply inform the user with a warning
115          about possible click sounds and reduce the volume ramp down
116          appropriately instead of cancelling the audio device connection
117    
118    Version 0.3.2 (24 June 2005)
119    
120      * packaging changes:
121      - updated autotools build files to compile on OS X      - updated autotools build files to compile on OS X
122        (conditional compilation of CoreMIDI and MidiShare drivers)        (conditional compilation of CoreMIDI and MidiShare drivers)
123      - hand-crafted assembly optimization code can be disabled with      - hand-crafted assembly optimization code can be disabled with
124        './configure --disable-asm' (definitely not recommended)        './configure --disable-asm' (definitely not recommended)
125        - fixed 'make dist' rule to include all necessary files
126        - require automake (>= 1.5) for 'make -f Makefile.cvs'
127          (due to 'dist-bzip2' automake option)
128    
129    * Gigasampler format engine:    * Gigasampler format engine:
130      - support for the gig parameters for "release velocity response" curves      - support for the gig parameters for "release velocity response" curves
# Line 12  Version CVS HEAD (?) Line 132  Version CVS HEAD (?)
132      - volume of release triggered samples now depends on note-on velocity,      - volume of release triggered samples now depends on note-on velocity,
133        note length and gig parameter "release trigger decay" instead of        note length and gig parameter "release trigger decay" instead of
134        note-off velocity.        note-off velocity.
135      - revised voice stealing (fixes crash caused by voice stealing)      - revised voice stealing
136              (fixes crash and endless loop caused by voice stealing)
137        - don't reset scale tuning on instrument or audio output device change
138        - handle key group conflicts right at the beginning of each fragment
139          instead of when the respective voice is actually launched
140          (fixes undefined behavior if stolen voices belonged to a key group -
141          this case was followed by a "killed voice survived" error message)
142        - fixed minor issue with null/silence samples
143          (those stole voices even though they don't need a voice at all which
144          resulted in "voice stealing didn't work out" messages)
145        - don't reset volume, pan, pitch and MIDI controller values on
146          instrument or audio output device change
147

150        - fixed LSCP event "CHANNEL_INFO" notification
151          (e.g. did not notify on volume changes or MIDI program change events)
152    
153      * linuxsampler application:
154        - added command line parameters --lscp-addr and --lscp-port to override
155          default IP address and port of LSCP server
