16        - do not automatically pick optimized gcc flags if the user already
17          provided some on his own (as CXXFLAGS)
18        - added compile time option to disable processing of All-Notes-Off MIDI
19          messages
20        - added compile time options to allow disabling the various audio and
21          MIDI drivers
22    
23    * Gigasampler format engine:    * Gigasampler format engine:
24        - extensive synthesis optimization
25          (reimplementation of EGs and LFO(s), removed synthesis parameter
26          prerendering and the synthesis parameter matrix in general, splitting
27          each audio fragment into subfragments now where each subfragment uses
28          constant pitch and filter coefficients. The volume coefficient is
29          linearly interpolated inside a subfragment, unless
30          --disable-interpolate-volume is set.)
31      - fine tuning of the EG modulation parameters      - fine tuning of the EG modulation parameters
32        - improved filter cutoff calculation by adding support for the
33          following gig parameters: Cutoff freq (used when no cutoff
34          controller is defined), Control invert, Minimum cutoff, Velocity
35          curve and Velocity range. The keyboard tracking now scales
36          cutoff frequency instead of resonance.
37        - added support for gig parameter Resonance.
38        - fixed bug in sysex handling (patch by Juan Linietsky)
39        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
40          which can be overridden with --enable-global-attenuation
41        - EG fixes: made the length of "attack hold" stage more
42          accurate. Release stage can now start before attack stage
43          ends. Cancel release didn't work when sustain was zero. Attack
44          time now has a minimal value to prevent clicks.
45        - fixed pitch changes larger than one octave
46        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
47        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
48          all modes can be altered via standard GM messages, that is CC5 for
49          altering portamento time, CC65 for enabling / disabling portamento
50          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
51        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
52          parameter) and crossfade
53        - added support for the "attenuation controller threshold" gig
54          parameter
55        - added smoothing of volume changes caused by control change
56          messages
57        - sample loop parameters are now taken from the DimensionRegion
58          instead of the wave chunk
59        - fixed keyswitching for v3 gigs with a number of keyswitch splits
60          not equal to a power of two
61        - reimplementation of the filter algorithm. The new filter is more
62          accurate and supports all gig filter types, including bandreject
63          and lowpass turbo.
64        - real support for 24 bit samples - samples are not truncated to
65          16 bits anymore
66        - support for aftertouch (channel pressure, not polyphonic
67          aftertouch)
68    
69    * LSCP server:    * LSCP server:
70      - fixed application exit on broken pipe error (fixes bug #20)      - fixed application exit on broken pipe error (fixes bug #20)
71        - fixed the notification messages delay due to lack of
72          network activity (fixes bug #26)
73        - fixed parser bug which occured on space(s) within device parameters
74          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
75    
76      * audio driver:
77        - added aRts audio output driver (by no means RT safe)
78    
79      * MIDI driver:
80        - fixed legacy sysex code which caused dispatching of MIDI SysEx
81          messages several times instead of once
82        - API extension for MIDI drivers which already supply exact time stamps
83          for events (i.e. for offline rendering based MIDI drivers)
84    
85      * linuxsampler application:
86        - show available sampler engine types on startup
87    
88    * general changes:    * general changes:
89      - support for muting sampler channels and solo mode of the same, two new      - support for muting sampler channels and solo mode of the same, two new

93        (patch by Grigor Iliev, a bit adjusted). Also added configure option        (patch by Grigor Iliev, a bit adjusted). Also added configure option
94        --enable-process-muted-channels which can be used to enable the        --enable-process-muted-channels which can be used to enable the
95        processing of muted channels.        processing of muted channels.
96        - support for sostenuto pedal
97        - support for monitoring the total number of active voices
98          (new LSCP commands: GET TOTAL_VOICE_COUNT, GET TOTAL_VOICE_COUNT_MAX,
99          SUBSCRIBE TOTAL_VOICE_COUNT, UNSUBSCRIBE TOTAL_VOICE_COUNT)
100        - fixed some memory management errors
101        - fixed some concurrency problems that could lead to crashes when
102          LSCP commands were executed
