* little configure.in fix for PPC
  (patch by Ebrahim Mayat)

1 persson 696 Version CVS HEAD (?)
2    
3 schoenebeck 697 * packaging changes:
4 capela 868 - 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 schoenebeck 697 - 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 schoenebeck 715 - 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 schoenebeck 829 - do not automatically pick optimized gcc flags if the user already
17     provided some on his own (as CXXFLAGS)
18 schoenebeck 849 - added compile time option to disable processing of All-Notes-Off MIDI
19     messages
20 schoenebeck 852 - added compile time options to allow disabling the various audio and
21     MIDI drivers
22 schoenebeck 909 - fixed automatic GCC CPU switch detection on PPC
23     (patch by Ebrahim Mayat)
24 schoenebeck 697
25 persson 696 * Gigasampler format engine:
26 schoenebeck 738 - extensive synthesis optimization
27     (reimplementation of EGs and LFO(s), removed synthesis parameter
28     prerendering and the synthesis parameter matrix in general, splitting
29     each audio fragment into subfragments now where each subfragment uses
30 persson 830 constant pitch and filter coefficients. The volume coefficient is
31     linearly interpolated inside a subfragment, unless
32     --disable-interpolate-volume is set.)
33 persson 696 - fine tuning of the EG modulation parameters
34 persson 729 - improved filter cutoff calculation by adding support for the
35     following gig parameters: Cutoff freq (used when no cutoff
36     controller is defined), Control invert, Minimum cutoff, Velocity
37 persson 791 curve and Velocity range. The keyboard tracking now scales
38     cutoff frequency instead of resonance.
39 persson 877 - added support for gig parameter Resonance.
40 schoenebeck 775 - fixed bug in sysex handling (patch by Juan Linietsky)
41 schoenebeck 781 - added global volume attenuation of -9 dB (0.35f) to prevent clipping
42     which can be overridden with --enable-global-attenuation
43 persson 783 - EG fixes: made the length of "attack hold" stage more
44     accurate. Release stage can now start before attack stage
45 persson 797 ends. Cancel release didn't work when sustain was zero. Attack
46     time now has a minimal value to prevent clicks.
47 persson 799 - fixed pitch changes larger than one octave
48 schoenebeck 829 - fixed EG3 (pitch envelope) synthesis which was neutral all the time
49     - implemented portamento mode and solo mode (a.k.a 'mono mode'):
50     all modes can be altered via standard GM messages, that is CC5 for
51     altering portamento time, CC65 for enabling / disabling portamento
52     mode, CC126 for enabling solo mode and CC127 for disabling solo mode
53 persson 832 - fine tuning of the curves for volume (CC7), pan (CC10 and gig
54     parameter) and crossfade
55 persson 831 - added support for the "attenuation controller threshold" gig
56     parameter
57 persson 832 - added smoothing of volume changes caused by control change
58     messages
59 persson 865 - sample loop parameters are now taken from the DimensionRegion
60     instead of the wave chunk
61     - fixed keyswitching for v3 gigs with a number of keyswitch splits
62     not equal to a power of two
63 persson 877 - reimplementation of the filter algorithm. The new filter is more
64     accurate and supports all gig filter types, including bandreject
65     and lowpass turbo.
66 persson 903 - real support for 24 bit samples - samples are not truncated to
67     16 bits anymore
68     - support for aftertouch (channel pressure, not polyphonic
69     aftertouch)
70 persson 696
71 schoenebeck 711 * LSCP server:
72     - fixed application exit on broken pipe error (fixes bug #20)
73 iliev 793 - fixed the notification messages delay due to lack of
74     network activity (fixes bug #26)
75 schoenebeck 826 - fixed parser bug which occured on space(s) within device parameters
76     (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
77 schoenebeck 711
78 schoenebeck 838 * audio driver:
79     - added aRts audio output driver (by no means RT safe)
80    
81 schoenebeck 775 * MIDI driver:
82     - fixed legacy sysex code which caused dispatching of MIDI SysEx
83     messages several times instead of once
84 schoenebeck 906 - API extension for MIDI drivers which already supply exact time stamps
85     for events (i.e. for offline rendering based MIDI drivers)
86 schoenebeck 775
87 schoenebeck 900 * linuxsampler application:
88     - show available sampler engine types on startup
89    
90 schoenebeck 705 * general changes:
91     - support for muting sampler channels and solo mode of the same, two new
92     LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
93     fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
94     introduced for this, the behavior is the same like on a mixer console
95 iliev 716 (patch by Grigor Iliev, a bit adjusted). Also added configure option
96     --enable-process-muted-channels which can be used to enable the
97     processing of muted channels.
98 iliev 777 - support for sostenuto pedal
99 iliev 779 - support for monitoring the total number of active voices
100 iliev 778 (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
101     SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
102 persson 835 - fixed some memory management errors
103 persson 841 - fixed some concurrency problems that could lead to crashes when
104     LSCP commands were executed
105 schoenebeck 705
106 schoenebeck 692 Version 0.3.3 (15 July 2005)
107 schoenebeck 686
108     * packaging changes:
109     - fixed compilation with gcc 4.0
110    
111 schoenebeck 687 * Gigasampler format engine:
112     - LFO preprocessing was performed even though the respective LFO was
113     disabled by the instrument patch (minor efficiency fix)
114 schoenebeck 688 - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
115     for volume ramp downs in the same fragment (needed for current voice
116     stealing implementation) then simply inform the user with a warning
117     about possible click sounds and reduce the volume ramp down
118     appropriately instead of cancelling the audio device connection
119 schoenebeck 687
120 schoenebeck 677 Version 0.3.2 (24 June 2005)
121 schoenebeck 609
122     * packaging changes:
123     - updated autotools build files to compile on OS X
124     (conditional compilation of CoreMIDI and MidiShare drivers)
125 schoenebeck 617 - hand-crafted assembly optimization code can be disabled with
126     './configure --disable-asm' (definitely not recommended)
127 schoenebeck 654 - fixed 'make dist' rule to include all necessary files
128     - require automake (>= 1.5) for 'make -f Makefile.cvs'
129     (due to 'dist-bzip2' automake option)
130 schoenebeck 649
131     * Gigasampler format engine:
132     - support for the gig parameters for "release velocity response" curves
133     - fine tuning of the EGADSR envelope
134     - volume of release triggered samples now depends on note-on velocity,
135     note length and gig parameter "release trigger decay" instead of
136     note-off velocity.
137 schoenebeck 663 - revised voice stealing
138     (fixes crash and endless loop caused by voice stealing)
139 schoenebeck 659 - don't reset scale tuning on instrument or audio output device change
140 schoenebeck 668 - handle key group conflicts right at the beginning of each fragment
141     instead of when the respective voice is actually launched
142     (fixes undefined behavior if stolen voices belonged to a key group -
143     this case was followed by a "killed voice survived" error message)
144 schoenebeck 669 - fixed minor issue with null/silence samples
145     (those stole voices even though they don't need a voice at all which
146     resulted in "voice stealing didn't work out" messages)
147 schoenebeck 670 - don't reset volume, pan, pitch and MIDI controller values on
148     instrument or audio output device change
149 schoenebeck 654
150 schoenebeck 620 * LSCP server:
151 schoenebeck 654 - fixed some crashes (patch by Grigor Iliev, fixes #19)
152 schoenebeck 660 - fixed LSCP event "CHANNEL_INFO" notification
153 schoenebeck 670 (e.g. did not notify on volume changes or MIDI program change events)
154 schoenebeck 609
155 schoenebeck 668 * linuxsampler application:
156     - added command line parameters --lscp-addr and --lscp-port to override
157     default IP address and port of LSCP server
158    
159 schoenebeck 579 Version 0.3.1 (24 May 2005)
160    
161     * initial release
