* implemented portamento mode and solo mode (a.k.a 'mono mode'):
  all modes can be altered via standard GM messages, that is CC5 for
  altering portamento time, CC65 for enabling / disabling portamento
  mode, CC126 for enabling solo mode and CC127 for disabling solo mode
* fixed EG3 (pitch envelope) synthesis which was neutral all the time
* configure.in: do not automatically pick optimized gcc flags if the user
  already provided some on his own (as CXXFLAGS)

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 829 - do not automatically pick optimized gcc flags if the user already
14     provided some on his own (as CXXFLAGS)
15 schoenebeck 697
16 persson 696 * Gigasampler format engine:
17 schoenebeck 738 - extensive synthesis optimization
18     (reimplementation of EGs and LFO(s), removed synthesis parameter
19     prerendering and the synthesis parameter matrix in general, splitting
20     each audio fragment into subfragments now where each subfragment uses
21     constant synthesis parameters - that is volume, pitch and filter
22     coefficients)
23 persson 696 - fine tuning of the EG modulation parameters
24 persson 729 - improved filter cutoff calculation by adding support for the
25     following gig parameters: Cutoff freq (used when no cutoff
26     controller is defined), Control invert, Minimum cutoff, Velocity
27 persson 791 curve and Velocity range. The keyboard tracking now scales
28     cutoff frequency instead of resonance.
29     - filter fine tuning: calculation of cutoff frequency and
30     bandwidth improved. Removed use of "BasicBPFilter". Changed
31     bandpass filter from constant peak to constant skirt. Added
32     support for gig parameter Resonance.
33 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
34 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
35     which can be overridden with --enable-global-attenuation
36 persson 783 - EG fixes: made the length of "attack hold" stage more
37     accurate. Release stage can now start before attack stage
38 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
39     time now has a minimal value to prevent clicks.
40 persson 799 - fixed pitch changes larger than one octave
41 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
42     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
43     all modes can be altered via standard GM messages, that is CC5 for
44     altering portamento time, CC65 for enabling / disabling portamento
45     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
46 persson 696
47 schoenebeck 711 * LSCP server:
48     - fixed application exit on broken pipe error (fixes bug #20)
49 iliev 793 - fixed the notification messages delay due to lack of
50     network activity (fixes bug #26)
51 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
52     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
53 schoenebeck 711
54 schoenebeck 775 * MIDI driver:
55     - fixed legacy sysex code which caused dispatching of MIDI SysEx
56     messages several times instead of once
57    
58 schoenebeck 705 * general changes:
59     - support for muting sampler channels and solo mode of the same, two new
60     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
61     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
62     introduced for this, the behavior is the same like on a mixer console
63 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
64     --enable-process-muted-channels which can be used to enable the
65     processing of muted channels.
66 iliev 777 - support for sostenuto pedal
67 iliev 779 - support for monitoring the total number of active voices
68 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
69     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
70 schoenebeck 705
71 schoenebeck 692 Version 0.3.3 (15 July 2005)
72 schoenebeck 686
73     * packaging changes:
74     - fixed compilation with gcc 4.0
75    
76 schoenebeck 687 * Gigasampler format engine:
77     - LFO preprocessing was performed even though the respective LFO was
78     disabled by the instrument patch (minor efficiency fix)
79 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
80     for volume ramp downs in the same fragment (needed for current voice
81     stealing implementation) then simply inform the user with a warning
82     about possible click sounds and reduce the volume ramp down
83     appropriately instead of cancelling the audio device connection
84 schoenebeck 687
85 schoenebeck 677 Version 0.3.2 (24 June 2005)
86 schoenebeck 609
87     * packaging changes:
88     - updated autotools build files to compile on OS X
89     (conditional compilation of CoreMIDI and MidiShare drivers)
90 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
91     './configure --disable-asm' (definitely not recommended)
92 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
93     - require automake (>= 1.5) for 'make -f Makefile.cvs'
94     (due to 'dist-bzip2' automake option)
95 schoenebeck 649
96     * Gigasampler format engine:
97     - support for the gig parameters for "release velocity response" curves
98     - fine tuning of the EGADSR envelope
99     - volume of release triggered samples now depends on note-on velocity,
100     note length and gig parameter "release trigger decay" instead of
101     note-off velocity.
102 schoenebeck 663 - revised voice stealing
103     (fixes crash and endless loop caused by voice stealing)
104 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
105 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
106     instead of when the respective voice is actually launched
107     (fixes undefined behavior if stolen voices belonged to a key group -
108     this case was followed by a "killed voice survived" error message)
109 schoenebeck 669 - fixed minor issue with null/silence samples
110     (those stole voices even though they don't need a voice at all which
111     resulted in "voice stealing didn't work out" messages)
112 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
113     instrument or audio output device change
114 schoenebeck 654
115 schoenebeck 620 * LSCP server:
116 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
117 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
118 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
119 schoenebeck 609
120 schoenebeck 668 * linuxsampler application:
121     - added command line parameters --lscp-addr and --lscp-port to override
122     default IP address and port of LSCP server
123    
124 schoenebeck 579 Version 0.3.1 (24 May 2005)
125    
126     * initial release
