* Added new LSCP commands: GET TOTAL_VOICE_COUNT,
GET TOTAL_VOICE_COUNT_MAX, SUBSCRIBE/UNSUBSCRIBE TOTAL_VOICE_COUNT

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
29 * LSCP server:
30 - fixed application exit on broken pipe error (fixes bug #20)
31
32 * MIDI driver:
33 - fixed legacy sysex code which caused dispatching of MIDI SysEx
34 messages several times instead of once
35
36 * general changes:
37 - support for muting sampler channels and solo mode of the same, two new
38 LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
39 fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
40 introduced for this, the behavior is the same like on a mixer console
41 (patch by Grigor Iliev, a bit adjusted). Also added configure option
42 --enable-process-muted-channels which can be used to enable the
43 processing of muted channels.
44 - support for sostenuto pedal
45 - support for monitoring the total number of active voices
46 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
47 SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
48
49 Version 0.3.3 (15 July 2005)
50
51 * packaging changes:
52 - fixed compilation with gcc 4.0
53
54 * Gigasampler format engine:
55 - LFO preprocessing was performed even though the respective LFO was
56 disabled by the instrument patch (minor efficiency fix)
57 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
58 for volume ramp downs in the same fragment (needed for current voice
59 stealing implementation) then simply inform the user with a warning
60 about possible click sounds and reduce the volume ramp down
61 appropriately instead of cancelling the audio device connection
62
63 Version 0.3.2 (24 June 2005)
64
65 * packaging changes:
66 - updated autotools build files to compile on OS X
67 (conditional compilation of CoreMIDI and MidiShare drivers)
68 - hand-crafted assembly optimization code can be disabled with
69 './configure --disable-asm' (definitely not recommended)
70 - fixed 'make dist' rule to include all necessary files
71 - require automake (>= 1.5) for 'make -f Makefile.cvs'
72 (due to 'dist-bzip2' automake option)
73
74 * Gigasampler format engine:
75 - support for the gig parameters for "release velocity response" curves
76 - fine tuning of the EGADSR envelope
77 - volume of release triggered samples now depends on note-on velocity,
78 note length and gig parameter "release trigger decay" instead of
79 note-off velocity.
80 - revised voice stealing
81 (fixes crash and endless loop caused by voice stealing)
82 - don't reset scale tuning on instrument or audio output device change
83 - handle key group conflicts right at the beginning of each fragment
84 instead of when the respective voice is actually launched
85 (fixes undefined behavior if stolen voices belonged to a key group -
86 this case was followed by a "killed voice survived" error message)
87 - fixed minor issue with null/silence samples
88 (those stole voices even though they don't need a voice at all which
89 resulted in "voice stealing didn't work out" messages)
90 - don't reset volume, pan, pitch and MIDI controller values on
91 instrument or audio output device change
92
93 * LSCP server:
94 - fixed some crashes (patch by Grigor Iliev, fixes #19)
95 - fixed LSCP event "CHANNEL_INFO" notification
96 (e.g. did not notify on volume changes or MIDI program change events)
97
98 * linuxsampler application:
99 - added command line parameters --lscp-addr and --lscp-port to override
100 default IP address and port of LSCP server
101
102 Version 0.3.1 (24 May 2005)
103
104 * initial release
