* 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 persson 696 Version CVS HEAD (?)
2    
3 schoenebeck 697 * 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 schoenebeck 715 - 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 schoenebeck 697
14 persson 696 * Gigasampler format engine:
15 schoenebeck 738 - 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 persson 696 - fine tuning of the EG modulation parameters
22 persson 729 - 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 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
28 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
29     which can be overridden with --enable-global-attenuation
30 persson 783 - 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 persson 696
34 persson 783
35 schoenebeck 711 * LSCP server:
36     - fixed application exit on broken pipe error (fixes bug #20)
37    
38 schoenebeck 775 * MIDI driver:
39     - fixed legacy sysex code which caused dispatching of MIDI SysEx
40     messages several times instead of once
41    
42 schoenebeck 705 * 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 iliev 716 (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 iliev 777 - support for sostenuto pedal
51 iliev 779 - support for monitoring the total number of active voices
52 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
53     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
54 schoenebeck 705
55 schoenebeck 692 Version 0.3.3 (15 July 2005)
56 schoenebeck 686
57     * packaging changes:
58     - fixed compilation with gcc 4.0
59    
60 schoenebeck 687 * Gigasampler format engine:
61     - LFO preprocessing was performed even though the respective LFO was
62     disabled by the instrument patch (minor efficiency fix)
63 schoenebeck 688 - 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 schoenebeck 687
69 schoenebeck 677 Version 0.3.2 (24 June 2005)
70 schoenebeck 609
71     * packaging changes:
72     - updated autotools build files to compile on OS X
73     (conditional compilation of CoreMIDI and MidiShare drivers)
74 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
75     './configure --disable-asm' (definitely not recommended)
76 schoenebeck 654 - 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 schoenebeck 649
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 schoenebeck 663 - revised voice stealing
87     (fixes crash and endless loop caused by voice stealing)
88 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
89 schoenebeck 668 - 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 schoenebeck 669 - 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 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
97     instrument or audio output device change
98 schoenebeck 654
99 schoenebeck 620 * LSCP server:
100 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
101 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
102 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
103 schoenebeck 609
104 schoenebeck 668 * 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 schoenebeck 579 Version 0.3.1 (24 May 2005)
109    
110     * initial release
