2    
3    * packaging changes:    * packaging changes:
4        - fixed building with newer MinGW-w64
5        - Mac OS X: support the new dir for Core Audio SDK
6        - Mac OS X: fixed building outside source directory
7        - made sure all source files for hostplugins are included when
8          doing "make dist"
9        - removed empty directories left from the cvs to svn migration
10        - fixed compilation with gcc 4.6.1
11        - another "make dist" fix, for the LV2 plugin
12        - made --enable-pthread-testcancel default on Mac OS X
13        - minor Makefile fix for building lscpparser when build and source
14          directories are separate
15        - Mac OS X: made it possible to specify plugin installation dir to
16          configure
17        - Mac OS X: Makefile fix for the install-strip target
18        - fixed compilation with gcc 4.7
19        - fixed configure script error with old autoconf versions
20        - lsatomic.h: use gcc provided atomic functions if building with
21          gcc 4.7 and C++11
22        - modernized configure script
23        - fixed linkage error when building with
24          LDFLAGS="-Wl,--no-undefined" (#190)
25        - fixed compilation with Clang 3.2
26        - removed usage of deprecated Automake variable INCLUDES
27        - fixed building with C++11
28        - build fix: ChangeFlagRelaxed.h was missing in makefile

30          makefiles
31        - fix for building with bison 3.0 (#202)
32    
33      * general changes:
34        - Refactoring: moved the independent code from
35          the Gigasampler format engine to base classes
36        - command line option '--profile' is currently disabled, since the
37          respective profiling code is currently broken
38        - Introduced support for optional environment variable
39          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
40          where the sampler shall look for instrument editor plugins
41          (patch by Luis Garrido, slightly modified).
42        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
43        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
44        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
45          note (in this implementation of the sampler its simply hard routed to
46          the 1st effect send of the sampler channel, no matter what the actual
47          effect type is)
48        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
49          note (in this implementation of the sampler its simply hard routed to
50          the 2nd effect send of the sampler channel, no matter what the actual
51          effect type is)
52        - implemented support for internal LADSPA effects
53        - raised limit of program change queue from 100 to 512
54          (as suggested by Alex Stone)
55        - implemented sine LFO, pulse LFO and saw LFO
56        - experimental support for per voice equalization
57        - added command line option --exec-after-init
58        - Introduced new C++ API method:
59          EngineChannel::InstrumentFileName(int index)
60          allowing to retrieve the whole list of files used for the loaded
61          instrument on an engine channel (a.k.a. part). Some GigaStudio
62          instruments for example are splitted over several files like
63          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
64        - Added new C++ API method Sampler::GetGlobalMaxVoices().
65        - Added new C++ API method Sampler::GetGlobalMaxStreams().
66        - Added new C++ API method Sampler::SetGlobalMaxVoices().
67        - Added new C++ API method Sampler::SetGlobalMaxStreams().
68        - Various "const" and "restrict" optimizations.
69        - all engines: add pan CC value to instrument pan parameter before
70          applying panning, instead of using two separate pan functions in
71          series (#182)
72        - added a lock guard class for exception safe mutex handling and
73          used it everywhere appropriate
74        - Immediately apply scale tuning changes to active voices.
75        - Exposed scale tuning to C++ API (along to the already existing standard
76          SysEx way).
77        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
78          and broken for ppc64. (Seq_cst loads and stores are actually not
79          used in LS, so the bug wasn't noticable.)
80        - lsatomic.h: added ARMv7 support
81    
82      * Gigasampler format engine:
83        - implemented the "round robin keyboard" dimension
84        - fixed round robin and random dimensions for cases when number of
85          dimension zones is not a power of two
86        - made round robin use a counter for each region instead of each
87          key
88        - bugfix: pitch LFO controller "internal+aftertouch" was broken
89        - bugfix: filter keyboard tracking was broken
90        - filter performance fix (an unnecessary copy was made of the
91          filter parameters in each sub fragment)
92        - handle special case when pan parameter in gig file has max or
93          min value
94        - Exclusive Groups: don't ever stop voices of the same note,
95          doesn't sound naturally with a drumkit
96        - fixed EG1 modulation when attack or release is zero
97    
98      * SFZ format engine:
99        - Initial implementation (not usable yet)
100        - added support for v2 multiple stage envelope generators
101        - added a fine-tuned v1 envelope generator instead of using the
102          one from the gig engine
103        - fixed memory leak and memory handling errors
104        - added support for trigger=first, trigger=legato and sw_previous
105        - allow non-numerical key values ("C#4" for example)
106        - "key" opcode now sets pitch_keycenter too
107        - fixed error when unloading instrument with same sample used by
108          multiple regions
109        - added some opcode aliases, like loopmode for loop_mode, to be
110          more compatible
111        - added support for trigger=release and rt_decay

268        - Listen to all interfaces on Mac OS X (INADDR_ANY)
269        - VST bugfix: If the host called resume() before and after
270          changing sample rate or block size, the number of channels was
271          incorrectly set to two. This caused silence in Cubase 5.
272        - save engine type (gig, sfz or sf2) in plugin state
273        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
274          64 bit Windows
275        - AU: changed number of output channels from one stereo to 16
276          stereo

284          loaded a second time (this time it's for Linux and Mac, previous
285          similar fix was for Windows)
286        - thread safety fixes for the instrument loading thread
287        - LV2: use the new lv2 package if present
288        - VST: try to open Fantasia automatically on Linux and Mac too (on
289          Linux, the Fantasia jar should be placed in <prefix>/share/java)
290        - VST: fixed crashes on Linux Ardour and EnergyXT
291        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
292          port and audio channel routing for DSSI plugins are now visible.
293        - LV2: use urid and atom extensions instead of deprecated uri-map
294          and event
295        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
296        - LV2: changed number of output channels to 16 stereo, just like
297          the VST and AU plugins
298        - LV2: fixed save/restore of SFZ state (patch by David Robillard)

305          the ALSA sequencer client name
306        - removed limit of maximum amount of MIDI ports per MIDI device, since
307          there is no reason for this limit
308        - MME: fixed memory handling bug found with cppcheck
309        - MME: removed compiler warning
310        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
311          which allows to retrieve the list of CoreMIDI clients / ports and to connect
312          to them a la JACK, via the usual sampler APIs
313        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
314          the driver will automatically connect to other CoreMIDI clients' ports
315          (e.g. external MIDI devices being attached to the Mac)
316        - added support for MIDI note on velocity filter
317        - CoreMIDI: fixed memory deallocation error
318        - Fixed variable underflow in VirtualMidiDevice, which caused graphical

321        - Implemented missing handling of MIDI "running status".
322        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
323        - MME bugfix: driver wasn't closed properly
324    
325      * audio driver:
326        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
327        - JACK audio: react on sample rate changes.
328        - JACK audio: react on buffer size changes.
329        - JACK audio: jack_port_get_buffer() was cached and called outside
330          RT context.
331        - ASIO driver: removed compiler warnings
332
