3      * general changes:
4        - replaced the old, confusing MIDI program change mechanism by a
5          flexible MIDI instrument mapper which allows to map arbitrary
6          (MIDI bank, MIDI program) pairs with arbitrary
7          (engine type, instrument file, file index) triplets which will be
8          loaded on the respective channel when such MIDI program change
9          messages arrive, beside that, each entry allows to define a life-time
10          strategy for the instrument, so the user can define whether the
11          instrument should i.e. be permanently loaded (to be able to switch
12          quickly among sounds) or i.e. loaded just on demand when the
13          respective program change arrives (to safe RAM space), as well as a
14          global volume factor for each entry, so the user can adjust the volume
15          dynamic of his mapped instrument collection without having to modify
16          the instrument files, also one can manage arbitrary amount of such
17          MIDI instrument maps and assign each sampler channel individually
18          a certain map, so that i.e. separation of normal instruments and
19          drumkits is possible
20        - new notification events for tracking audio/MIDI device changes,
21          MIDI instrument map changes and MIDI instrument changes
22        - sampler was limited to load max. 200 instruments in the background
23          due to a constant size RingBuffer FIFO which is now replaced by a
24          dynamic (unlimited) size std::list FIFO
25        - added FX sends, these allow to route audio signals to arbitrary audio
26          output channels for being processed by external effect processors
27          (i.e. jack-rack), the send levels are controllable via arbitrary MIDI
28          controllers
29        - global (sampler wide) volume can now be controlled at runtime
30    
31      * MIDI driver:
32        - dispatch bank select (MSB and LSB) messages
33    
34      * Gigasampler format engine:
35        - if a filter is used and EG2 finishes before EG1, let the voice
36          die when EG2 has finished (this fixes a problem with clicks and
37          voice starvation for some gigs)
38        - playback is no longer disabled during instrument loading
39        - all notes playing on a channel that changes its instrument keep
40          playing with the old instrument until they get a note off
41          command
42    
43      * Bug fixes:
44        - fixed crash occurring on certain LSCP scripts (Bug 39)
45        - another thread safety fix for lscp "load engine" and "set
46          channel audio output device"

51        - changed deprecated copyright attribute to license; added ldconfig
52          to post-(un)install steps; added devel package for liblinuxsampler;
53          to linuxsampler.spec (RPM)

63        - do not automatically pick optimized gcc flags if the user already

66          messages
67        - added compile time options to allow disabling the various audio and
68          MIDI drivers
69        - fixed automatic GCC CPU switch detection on PPC

85        cutoff frequency, not just resonance.        cutoff frequency instead of resonance.
86        - added support for gig parameter Resonance.
87      - fixed bug in sysex handling (patch by Juan Linietsky)      - fixed bug in sysex handling (patch by Juan Linietsky)
88        - added global volume attenuation of -9 dB (0.35f) to prevent clipping
89          which can be overridden with --enable-global-attenuation
90        - EG fixes: made the length of "attack hold" stage more
91          accurate. Release stage can now start before attack stage
92          ends. Cancel release didn't work when sustain was zero. Attack
93          time now has a minimal value to prevent clicks.
94        - fixed pitch changes larger than one octave
95        - fixed EG3 (pitch envelope) synthesis which was neutral all the time
96        - implemented portamento mode and solo mode (a.k.a 'mono mode'):
97          all modes can be altered via standard GM messages, that is CC5 for
98          altering portamento time, CC65 for enabling / disabling portamento
99          mode, CC126 for enabling solo mode and CC127 for disabling solo mode
100        - fine tuning of the curves for volume (CC7), pan (CC10 and gig
101          parameter) and crossfade
102        - added support for the "attenuation controller threshold" gig
103          parameter
104        - added smoothing of volume changes caused by control change
105          messages
106        - sample loop parameters are now taken from the DimensionRegion
107          instead of the wave chunk
108        - fixed keyswitching for v3 gigs with a number of keyswitch splits
109          not equal to a power of two
110        - reimplementation of the filter algorithm. The new filter is more
111          accurate and supports all gig filter types, including bandreject
112          and lowpass turbo.
113        - real support for 24 bit samples - samples are not truncated to
114          16 bits anymore
115        - support for aftertouch (channel pressure, not polyphonic
116          aftertouch)
117        - LFO1 behaviour fixed (dampening from max volume instead of
118          amplifying from 0)
119    
120    * LSCP server:    * LSCP server:
121      - fixed application exit on broken pipe error (fixes bug #20)      - fixed application exit on broken pipe error (fixes bug #20)
122        - fixed the notification messages delay due to lack of
123          network activity (fixes bug #26)
124        - fixed parser bug which occured on space(s) within device parameters
125          (e.g. "SET AUDIO_OUTPUT_CHANNEL_PARAMETER 0 0 SOMEPARAM='foo bar'")
126    
127      * audio driver:
128        - added aRts audio output driver (by no means RT safe)
129    
130    * MIDI driver:    * MIDI driver:

133        - API extension for MIDI drivers which already supply exact time stamps
134          for events (i.e. for offline rendering based MIDI drivers)
135        - added checks for bad MIDI data
136    
137      * linuxsampler application:
138        - show available sampler engine types on startup
139

152        - fixed some memory management errors
153        - fixed some concurrency problems that could lead to crashes when
154          LSCP commands were executed
155        - fixed crash when instrument loading failed previously on the same
