3    * packaging changes:    * 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    
31      * LSCP server:
32        - fixed application exit on broken pipe error (fixes bug #20)
33    
34      * MIDI driver:
35        - fixed legacy sysex code which caused dispatching of MIDI SysEx
36          messages several times instead of once
37    
38      * general changes:
39        - support for muting sampler channels and solo mode of the same, two new
40          LSCP commands ("SET CHANNEL MUTE" and "SET CHANNEL SOLO") and two new
41          fields ("MUTE" and "SOLO") for command "GET CHANNEL INFO" were
42          introduced for this, the behavior is the same like on a mixer console
43          (patch by Grigor Iliev, a bit adjusted). Also added configure option
44          --enable-process-muted-channels which can be used to enable the
45          processing of muted channels.
46        - support for sostenuto pedal
47        - support for monitoring the total number of active voices
48          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
49          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
50    
51    Version 0.3.3 (15 July 2005)
52    
53      * packaging changes:
54        - fixed compilation with gcc 4.0
55    
56      * Gigasampler format engine:
57        - LFO preprocessing was performed even though the respective LFO was
58          disabled by the instrument patch (minor efficiency fix)
59        - if period time of chosen audio device is too small (< MIN_RELEASE_TIME)
60          for volume ramp downs in the same fragment (needed for current voice
61          stealing implementation) then simply inform the user with a warning
62          about possible click sounds and reduce the volume ramp down
63          appropriately instead of cancelling the audio device connection
64    
65    Version 0.3.2 (24 June 2005)
66    
67      * packaging changes:
68      - updated autotools build files to compile on OS X      - updated autotools build files to compile on OS X

92        - don't reset volume, pan, pitch and MIDI controller values on
93          instrument or audio output device change
