      to post-(un)install steps; added devel package for liblinuxsampler;
      to linuxsampler.spec (RPM)

1 Version CVS HEAD (?)
2
3 * 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 - filter fine tuning: calculation of cutoff frequency and
38 bandwidth improved. Removed use of "BasicBPFilter". Changed
39 bandpass filter from constant peak to constant skirt. Added
40 support for gig parameter Resonance.
41 - fixed bug in sysex handling (patch by Juan Linietsky)
42 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
43 which can be overridden with --enable-global-attenuation
44 - EG fixes: made the length of "attack hold" stage more
45 accurate. Release stage can now start before attack stage
46 ends. Cancel release didn't work when sustain was zero. Attack
47 time now has a minimal value to prevent clicks.
48 - fixed pitch changes larger than one octave
49 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
50 - implemented portamento mode and solo mode (a.k.a 'mono mode'):
51 all modes can be altered via standard GM messages, that is CC5 for
52 altering portamento time, CC65 for enabling / disabling portamento
53 mode, CC126 for enabling solo mode and CC127 for disabling solo mode
54 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
55 parameter) and crossfade
56 - added support for the "attenuation controller threshold" gig
57 parameter
58 - added smoothing of volume changes caused by control change
59 messages
60 - sample loop parameters are now taken from the DimensionRegion
61 instead of the wave chunk
62 - fixed keyswitching for v3 gigs with a number of keyswitch splits
63 not equal to a power of two
64
65 * LSCP server:
66 - fixed application exit on broken pipe error (fixes bug #20)
67 - fixed the notification messages delay due to lack of
68 network activity (fixes bug #26)
69 - fixed parser bug which occured on space(s) within device parameters
70 (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
71
72 * audio driver:
73 - added aRts audio output driver (by no means RT safe)
74
75 * MIDI driver:
76 - fixed legacy sysex code which caused dispatching of MIDI SysEx
77 messages several times instead of once
78
79 * general changes:
80 - support for muting sampler channels and solo mode of the same, two new
81 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
82 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
83 introduced for this, the behavior is the same like on a mixer console
84 (patch by Grigor Iliev, a bit adjusted). Also added configure option
85 --enable-process-muted-channels which can be used to enable the
86 processing of muted channels.
87 - support for sostenuto pedal
88 - support for monitoring the total number of active voices
89 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
90 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
91 - fixed some memory management errors
92 - fixed some concurrency problems that could lead to crashes when
93 LSCP commands were executed
94
95 Version 0.3.3 (15 July 2005)
96
97 * packaging changes:
98 - fixed compilation with gcc 4.0
99
100 * Gigasampler format engine:
101 - LFO preprocessing was performed even though the respective LFO was
102 disabled by the instrument patch (minor efficiency fix)
103 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
104 for volume ramp downs in the same fragment (needed for current voice
105 stealing implementation) then simply inform the user with a warning
106 about possible click sounds and reduce the volume ramp down
107 appropriately instead of cancelling the audio device connection
108
109 Version 0.3.2 (24 June 2005)
110
111 * packaging changes:
112 - updated autotools build files to compile on OS X
113 (conditional compilation of CoreMIDI and MidiShare drivers)
114 - hand-crafted assembly optimization code can be disabled with
115 './configure --disable-asm' (definitely not recommended)
116 - fixed 'make dist' rule to include all necessary files
117 - require automake (>= 1.5) for 'make -f Makefile.cvs'
118 (due to 'dist-bzip2' automake option)
119
120 * Gigasampler format engine:
121 - support for the gig parameters for "release velocity response" curves
122 - fine tuning of the EGADSR envelope
123 - volume of release triggered samples now depends on note-on velocity,
124 note length and gig parameter "release trigger decay" instead of
125 note-off velocity.
126 - revised voice stealing
127 (fixes crash and endless loop caused by voice stealing)
128 - don't reset scale tuning on instrument or audio output device change
129 - handle key group conflicts right at the beginning of each fragment
130 instead of when the respective voice is actually launched
131 (fixes undefined behavior if stolen voices belonged to a key group -
132 this case was followed by a "killed voice survived" error message)
133 - fixed minor issue with null/silence samples
134 (those stole voices even though they don't need a voice at all which
135 resulted in "voice stealing didn't work out" messages)
136 - don't reset volume, pan, pitch and MIDI controller values on
137 instrument or audio output device change
138
139 * LSCP server:
140 - fixed some crashes (patch by Grigor Iliev, fixes #19)
141 - fixed LSCP event "CHANNEL_INFO" notification
142 (e.g. did not notify on volume changes or MIDI program change events)
143
144 * linuxsampler application:
145 - added command line parameters --lscp-addr and --lscp-port to override
146 default IP address and port of LSCP server
147
148 Version 0.3.1 (24 May 2005)
149
150 * initial release
