* EG fixes: the length of "attack hold" stage was wrong. Release stage
  can now start before attack stage ends. Cancel release didn't work
  when sustain was zero.

1 Version CVS HEAD (?)
2
3 * packaging changes:
4 - install necessary development header files for allowing 3rd party
5 applications to link against liblinuxsampler
6 - liblinuxsampler's API documentation can be generated with 'make docs'
7 (Doxygen required)
8 - added benchmark to automatically detect the best triangle LFO
9 implementation (currently either an integer math solution or a
10 di-harmonic approximation), automatic detection can be overriden
11 with --enable-signed-triang-algo=x and --enable-unsigned-triang-algo=x
12 configure script argument though (mandatory for cross-compilation)
13
14 * Gigasampler format engine:
15 - extensive synthesis optimization
16 (reimplementation of EGs and LFO(s), removed synthesis parameter
17 prerendering and the synthesis parameter matrix in general, splitting
18 each audio fragment into subfragments now where each subfragment uses
19 constant synthesis parameters - that is volume, pitch and filter
20 coefficients)
21 - fine tuning of the EG modulation parameters
22 - improved filter cutoff calculation by adding support for the
23 following gig parameters: Cutoff freq (used when no cutoff
24 controller is defined), Control invert, Minimum cutoff, Velocity
25 curve and Velocity range. The keyboard tracking now also scales
26 cutoff frequency, not just resonance.
27 - fixed bug in sysex handling (patch by Juan Linietsky)
28 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
29 which can be overridden with --enable-global-attenuation
30 - EG fixes: made the length of "attack hold" stage more
31 accurate. Release stage can now start before attack stage
32 ends. Cancel release didn't work when sustain was zero.
33
34
35 * LSCP server:
36 - fixed application exit on broken pipe error (fixes bug #20)
37
38 * MIDI driver:
39 - fixed legacy sysex code which caused dispatching of MIDI SysEx
40 messages several times instead of once
41
42 * general changes:
43 - support for muting sampler channels and solo mode of the same, two new
44 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
45 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
46 introduced for this, the behavior is the same like on a mixer console
47 (patch by Grigor Iliev, a bit adjusted). Also added configure option
48 --enable-process-muted-channels which can be used to enable the
49 processing of muted channels.
50 - support for sostenuto pedal
51 - support for monitoring the total number of active voices
52 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
53 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
54
55 Version 0.3.3 (15 July 2005)
56
57 * packaging changes:
58 - fixed compilation with gcc 4.0
59
60 * Gigasampler format engine:
61 - LFO preprocessing was performed even though the respective LFO was
62 disabled by the instrument patch (minor efficiency fix)
63 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
64 for volume ramp downs in the same fragment (needed for current voice
65 stealing implementation) then simply inform the user with a warning
66 about possible click sounds and reduce the volume ramp down
67 appropriately instead of cancelling the audio device connection
68
69 Version 0.3.2 (24 June 2005)
70
71 * packaging changes:
72 - updated autotools build files to compile on OS X
73 (conditional compilation of CoreMIDI and MidiShare drivers)
74 - hand-crafted assembly optimization code can be disabled with
75 './configure --disable-asm' (definitely not recommended)
76 - fixed 'make dist' rule to include all necessary files
77 - require automake (>= 1.5) for 'make -f Makefile.cvs'
78 (due to 'dist-bzip2' automake option)
79
80 * Gigasampler format engine:
81 - support for the gig parameters for "release velocity response" curves
82 - fine tuning of the EGADSR envelope
83 - volume of release triggered samples now depends on note-on velocity,
84 note length and gig parameter "release trigger decay" instead of
85 note-off velocity.
86 - revised voice stealing
87 (fixes crash and endless loop caused by voice stealing)
88 - don't reset scale tuning on instrument or audio output device change
89 - handle key group conflicts right at the beginning of each fragment
90 instead of when the respective voice is actually launched
91 (fixes undefined behavior if stolen voices belonged to a key group -
92 this case was followed by a "killed voice survived" error message)
93 - fixed minor issue with null/silence samples
94 (those stole voices even though they don't need a voice at all which
95 resulted in "voice stealing didn't work out" messages)
96 - don't reset volume, pan, pitch and MIDI controller values on
97 instrument or audio output device change
98
99 * LSCP server:
100 - fixed some crashes (patch by Grigor Iliev, fixes #19)
101 - fixed LSCP event "CHANNEL_INFO" notification
102 (e.g. did not notify on volume changes or MIDI program change events)
103
104 * linuxsampler application:
105 - added command line parameters --lscp-addr and --lscp-port to override
106 default IP address and port of LSCP server
107
108 Version 0.3.1 (24 May 2005)
109
110 * initial release
