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

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

22        - modernized configure script
23        - fixed linkage error when building with
24          LDFLAGS="-Wl,--no-undefined" (#190)

31        - fix for building with bison 3.0 (#202)
32        - Mac OS X: added temporary hack allowing to spawn gigedit as callback
33          on the process's main thread
34        - fixed build error on newer MinGW
35        - support building with older jack versions
36        - support building with spaces in vst sdk path
37        - enabled automake 'subdir-objects' option and moved external
38          source references (vst, au, asio) from makefiles to cpp files,
39          in order to get rid of warnings from automake 1.14
40    
41      * general changes:
42        - Refactoring: moved the independent code from
43          the Gigasampler format engine to base classes
44        - command line option '--profile' is currently disabled, since the
45          respective profiling code is currently broken
46        - Introduced support for optional environment variable
47          "LINUXSAMPLER_PLUGIN_DIR" which allows to override the directory
48          where the sampler shall look for instrument editor plugins
49          (patch by Luis Garrido, slightly modified).
50        - implemented Roland GS NRPN 1ArrH which allows to set volume per note
51        - implemented Roland GS NRPN 1CrrH which allows to set pan per note
52        - implemented Roland GS NRPN 1DrrH which allows to set reverb send per
53          note (in this implementation of the sampler its simply hard routed to
54          the 1st effect send of the sampler channel, no matter what the actual
55          effect type is)
56        - implemented Roland GS NRPN 1ErrH which allows to set chorus send per
57          note (in this implementation of the sampler its simply hard routed to
58          the 2nd effect send of the sampler channel, no matter what the actual
59          effect type is)
60        - implemented support for internal LADSPA effects
61        - raised limit of program change queue from 100 to 512
62          (as suggested by Alex Stone)
63        - implemented sine LFO, pulse LFO and saw LFO
64        - experimental support for per voice equalization
65        - added command line option --exec-after-init
66        - Introduced new C++ API method:
67          EngineChannel::InstrumentFileName(int index)
68          allowing to retrieve the whole list of files used for the loaded
69          instrument on an engine channel (a.k.a. part). Some GigaStudio
70          instruments for example are splitted over several files like
71          "Foo.gig", "Foo.gx01", "Foo.gx02", ...
72        - Added new C++ API method Sampler::GetGlobalMaxVoices().
73        - Added new C++ API method Sampler::GetGlobalMaxStreams().
74        - Added new C++ API method Sampler::SetGlobalMaxVoices().
75        - Added new C++ API method Sampler::SetGlobalMaxStreams().
76        - Various "const" and "restrict" optimizations.
77        - all engines: add pan CC value to instrument pan parameter before
78          applying panning, instead of using two separate pan functions in
79          series (#182)
80        - added a lock guard class for exception safe mutex handling and
81          used it everywhere appropriate
82        - Immediately apply scale tuning changes to active voices.
83        - Exposed scale tuning to C++ API (along to the already existing standard
84          SysEx way).
85        - lsatomic.h fixes: seq_cst load and store were suboptimal for x86
86          and broken for ppc64. (Seq_cst loads and stores are actually not
87          used in LS, so the bug wasn't noticable.)
88        - lsatomic.h: added ARMv7 support
89        - Added support for multiple MIDI input ports per sampler channel (and
90          added various new C++ methods for this new feature / design change, old
91          C++ API methods for managing SamplerChannel's MIDI inputs are now marked
92          as deprecated but are still there and should provide full behavior
93          backward compatibility).
94        - AbstractEngine::GSChecksum(): don't allocate memory on the stack (was
95          unsafe and caused compilation error with clang 2.x).
96        - Bugfix: only process the latest MIDI program change event.
97        - Introducing the LSCP shell, which provides convenient control of the
98          sampler from the command line by providing LSCP aware features.
99        - VirtualMidiDevice: Added support for program change.
100        - VirtualMidiDevice: Added support for bank select (MSB & LSB).
101        - VirtualMidiDevice: Added support for pitch bend.
102        - Aftertouch: extended API to explicitly handle channel pressure and
103          polyphonic key pressure events (so far polyphonic pressure was not
104          supported at all, and channel pressure was rerouted as CC128 but not
105          used so far).
106        - Added initial support for real-time instrument scripts. The script VM
107          code is shared by all sampler engine implemementations, however only the
108          gig file format currently provides support for storing instrument scripts
109          (as LinuxSampler extension to the original GigaStudio 4 format).
110    
111      * Gigasampler format engine:
112        - implemented the "round robin keyboard" dimension
113        - fixed round robin and random dimensions for cases when number of
114          dimension zones is not a power of two
115        - made round robin use a counter for each region instead of each
116          key
117        - bugfix: pitch LFO controller "internal+aftertouch" was broken
118        - bugfix: filter keyboard tracking was broken
119        - filter performance fix (an unnecessary copy was made of the
120          filter parameters in each sub fragment)
121        - handle special case when pan parameter in gig file has max or
122          min value
123        - Exclusive Groups: don't ever stop voices of the same note,
124          doesn't sound naturally with a drumkit
125        - fixed EG1 modulation when attack or release is zero
126        - Fixed support for 'aftertouch' attenuation controller.
127        - Fixed crash that happened with velocity split sounds under certain
128          conditions (see also previous commit on libgig).

149        - fine-tuned the default velocity curve
150        - added support for transpose
151        - fixed crash when using sw_down/up
152        - improved logic for sw_lokey/hikey/up/down/last
153        - added more v1 aliases to parser
154        - reduced memory usage for sfz data
155        - RT-safeness: avoid malloc in audio thread
156        - fixed a bug that could cause voice stealing to fail

290          (modified patch which was originally posted by Sergey on LS mailing list)
291        - bugfix: generation of velocity curves etc should not be done
292          after each "#include", only after the main file is parsed
293        - bugfix: line numbers in error messages were wrong after "#include"
294        - added support for float and 32 bit sample files
295    
296      * SoundFont format engine:
297        - Initial implementation (not usable yet)

301        - initial implementation of Vibrato LFO and Modulation LFO
302        - initial implementation of cutoff filter
303        - use linear decay and release for filter and pitch EG

305      * Host plugins (VST, AU, LV2, DSSI):
306        - AU bugfix: failed to destroy its audio/MIDI devices
307        - Listen to all interfaces on Mac OS X (INADDR_ANY)
308        - VST bugfix: If the host called resume() before and after
309          changing sample rate or block size, the number of channels was
310          incorrectly set to two. This caused silence in Cubase 5.
311        - save engine type (gig, sfz or sf2) in plugin state
312        - VST: when opening Fantasia, look for both 32 and 64 bit Java on
313          64 bit Windows
314        - AU: changed number of output channels from one stereo to 16
315          stereo
316        - VST: made it possible to build the VST plugin for Mac

318          specified
319        - LV2 "state" extension support (patch by David Robillard)
320        - VST bugfix: instrument loading hang and crashed the host when
321          the plugin was loaded a second time (#174)
322        - plugin bugfix: instrument loading hang when the plugin was
323          loaded a second time (this time it's for Linux and Mac, previous
324          similar fix was for Windows)
325        - thread safety fixes for the instrument loading thread
326        - LV2: use the new lv2 package if present
327        - VST: try to open Fantasia automatically on Linux and Mac too (on
328          Linux, the Fantasia jar should be placed in <prefix>/share/java)
329        - VST: fixed crashes on Linux Ardour and EnergyXT
330        - DSSI bugfix: it wasn't possible to change engine type. The MIDI
331          port and audio channel routing for DSSI plugins are now visible.
332        - LV2: use urid and atom extensions instead of deprecated uri-map
333          and event
334        - LV2: lv2 package 1.0 is now required to build the LV2 plugin
335        - LV2: changed number of output channels to 16 stereo, just like
336          the VST and AU plugins
337        - LV2: fixed save/restore of SFZ state (patch by David Robillard)

343        - Changed instrument editor plugin interface, providing additional
344          informations like the EngineChannel for which the instrument editor was
345          spawned for. This allows the instrument editors to interact more actively
346          with the sampler.
347    
348      * MIDI driver:
349        - ALSA MIDI driver supports now "NAME" device parameter, for overriding
350          the ALSA sequencer client name

354        - MME: removed compiler warning
355        - CoreMIDI: implemented driver specific port parameter "CORE_MIDI_BINDINGS",
356          which allows to retrieve the list of CoreMIDI clients / ports and to connect
357          to them a la JACK, via the usual sampler APIs
358        - CoreMIDI: added driver specific port parameter "AUTO_BIND", if enabled
359          the driver will automatically connect to other CoreMIDI clients' ports
360          (e.g. external MIDI devices being attached to the Mac)
361        - added support for MIDI note on velocity filter
362        - CoreMIDI: fixed memory deallocation error
363        - Fixed variable underflow in VirtualMidiDevice, which caused graphical
364          virtual keyboards in frontends / instrument editors being stuck.
365        - Bugfix in VirtualMidiDevice: process note on with velocity 0 as note off.
366        - Implemented missing handling of MIDI "running status".
367        - CoreMIDI fix: a MIDIPacket can contain more than one event per packet.
368        - MME bugfix: driver wasn't closed properly
369        - CoreMIDI: automatically connect to all input sources by default (driver
370          parameter "AUTO_BIND").
371        - CoreMIDI: fixed auto bind feature to CoreMIDI ports that go online
372        - CoreMIDI: fixed minor memory leak
373    
374      * audio driver:
375        - ASIO driver fixes for newer gcc versions (fix from PortAudio)
376        - JACK audio: react on sample rate changes.
377        - JACK audio: react on buffer size changes.
378        - JACK audio: jack_port_get_buffer() was cached and called outside
379          RT context.
380        - ASIO driver: removed compiler warnings
381        - CoreAudio: fixed minor error handling bug
382        - ASIO driver: be more verbose when no ASIO card could be found (fixes #203)
383        - JACK audio: return the JACK server's current sample rate as default value
384          for audio device parameter "SAMPLERATE" (fixes #166).
385    
386      * LSCP server:
387        - added support for sending MIDI CC messages via LSCP command

505          after MIDI/audio device creation failure
506        - When creating MIDI instrument map entries with "PERSISTENT" type, the
507          instruments were uselessly precached with zero samples, however it still
508          took the full preloading time and on 1st program change the respective
509          instrument was completely reloaded again.
510        - fixed handling of rapid bank select and program change messages
511          sent to the same sampler channel (patch from the Open Octave

525          introduced in previous fix)
526        - fixed crash when a channel received a program change while
527          playing a note in a key group
528        - fixed erroneous error message piping in VoiceBase.h
529          (labelled "Disk stream not available in time")
530        - Update effects on sample rate & period size changes (to avoid
531          crashes and noise on such transitions).
532        - ignore missing LADSPA paths without ignoring valid LADSPA paths
533          (fixes #208)
534        - Fixed bug in LSCP grammar definition which caused a statement like
535          "GET SERVER INFOasdf\n" to be accepted as valid statement (was so far
536          practically irrelevant, however it caused problems with the new LSCP
537          shell's auto completion feature).
538        - Fixed MIDI program change messages being ignored if quickly executed
539          after each other (fixes #231).
